Homemade overpass for repairs. Do-it-yourself overpass: features of manufacturing different options. overpass designed for partial entry of cars

If you don’t have an inspection hole for your car, you can replace it with a flyover you made yourself in the garage or at your dacha. To do this you will need a couple of sleepers and a few thick boards or some scrap metal, a welding machine and a grinder. Of course, a pit in a garage is more convenient, but for various reasons not every garage can be equipped with one. The proximity of underground communications or groundwater, and then, if you want to repair your personal car, the solution for you will be to build an overpass with your own hands.

Types of overpasses

Depending on the size, there are two types of overpasses for cars:

For access to one vehicle axle.
For entry of the entire car.

Mini overpass The first category is usually collapsible and requires a small amount of material to make it yourself. It is mobile, but not as convenient for do-it-yourself car repairs as a full-size one. The inconvenience of a mini overpass is that due to its small height, repairing a car with your own hands with its help is far from being possible at full height.

There are two types of devices that provide access to both the front and rear of the machine:

Installed on level ground. Entry to their site for repairs occurs at best at an angle of about 30° to the horizontal.
Located on a slope. Entry to them occurs without climbing up (horizontally).

For those who want to make a mini overpass for car repairs with their own hands, we present the simplest design, which does not require drawings to repeat.

So, to make the simplest mini overpass for a car with your own hands, you need to lay two pairs of sleepers in pairs with their side surfaces facing each other and connect the sleepers of each pair to each other using steel brackets. Turn them over with the staples facing down and cut one end of each pair at an angle of about 30° to the horizontal for ease of entry. Lay the pairs parallel to each other, in accordance with the track width of your car, with the cut ends facing the same direction. The portable mini overpass is ready. The height of such a structure is adjusted by placing scraps of boards of suitable thickness under the rectangular ends of the sleepers. To prevent the car from rolling off the overpass, make shoes from scraps of boards and place them under the wheels during repairs. In order to avoid falling from the structure when entering it, attach two pieces of board to the ends of the sleepers so that they stick out slightly upward.

To work under the car on such an overpass, be sure to get a piece of thick felt or at least an old cotton blanket. Don't leave your health on the concrete floor.

To those who say that the car can be raised to such a height, I will object that if you put thick blocks under it, then not every jack can lift it that much, and secondly, it’s much safer than using a jack.

Full size design

For those who do not want to endure the inconvenience of repairing their car, we suggest making a full-size version with your own hands. It will be more convenient for you to drive onto it if you build it on a slope. And it will take less boards. So it makes sense to look for a place for her on the slope. Of course, it is better to make the overpass from metal: it is stronger, does not absorb oil and does not rust as quickly as wood rots. But if you have wood in stock, then the choice of material is obvious; don’t buy rental material.

Metal installation

Two can be used as supports steel pipes with a diameter of at least 150 mm. They should be buried in the ground below its freezing level, otherwise the height of the overpass with the onset of winter will increase and decrease in the spring. After installing the supports, the pits should be compacted with broken bricks, or better yet, concreted. If the depth of soil freezing in your area is small, bury the supports into the ground at least a meter. The height of the supports above the ground depends on your height, but should not be lower than 1.5 meters.

They should be installed at a distance of about 5 meters from the intended entrance to the overpass, and at a distance from each other equal to the track of your car. Place a piece of channel about 150 mm wide on top of the supports, edges down; its length should be 50 cm greater than the track width of your car. Weld the channel to the supports. After this, for lateral stability of the structure, connect the supports crosswise with two corners. Place four corners with ribs of at least 7.5 cm and a length of about 5 m in pairs parallel with the ribs facing each other, and fill the space between each pair with pieces of reinforcement 50 cm long and weld them to each, maintaining a right angle. Lay the resulting ladders so that one side of each is on the edge of the channel, and the other on the ground. Check their horizontalness using a level. And also set the width between the centers of the edges lying on the ground, which should be equal to the track of your car. Weld them to the channel, and to them stops to prevent falling vehicle, and congratulations, you have welded a steel overpass with your own hands.

Features of a wooden structure

Instead of a pipe, two pieces of timber with a cross-section of at least 15 × 15 cm are used as supports.
Parts of supports dug into the ground must be impregnated with creosote or at least mining for durability.
Each ladder should be assembled from two boards 5 cm thick, one of them 10 to 15 cm wide should be placed on its edge. Place the other one, about 40 cm wide, flat on top and nail it to the first one with nails or screw it with screws.
In each beam it is necessary to make one cut 5 cm wide and deep in accordance with the width of the boards placed on edge. The cuts are made in order to insert the lower boards of the ladders into them. The crossbar should be attached to the supports not from the top at the ends, but from the front, just below the ladder board coming out of the cut.
The supports can be made by screwing two pieces of block wood onto the supports with self-tapping screws, so that they stick out above the ladders.
To reduce the likelihood of wheels slipping from the edges of the ramps, it is advisable to make ribs. One option is to attach a board about 2 cm thick and 10 cm wide to the end of the top board of the ladder. Attach better with self-tapping screws with flat caps 50 mm long.
Below the crossbar, for lateral stability of the structure, the supports must be fastened together crosswise with two boards.

The car periodically requires inspection of the chassis. An overpass is used for this. The design is used at maintenance points. If the car owner does not want to spend money on the work of auto repairmen, he can inspect the car himself by raising it above the ground on an overpass. This is an alternative way to the inspection hole to gain access to the bottom. Assembling the overpass yourself will save money.

Based on the type of construction, there are two types of overpasses for cars:

Full-size ones allow you to repair a machine that is completely raised above ground level by 1 meter. They are bulky and require a lot of space. Suitable for both passenger cars and trucks.
Mini overpass. It consists of two small, independent from each other, beveled on one side of the podium. The auto overpass allows you to lift the car from the front or rear wheels. Used for partial inspection of the bottom. The disadvantage of this design was the need for the driver to have pinpoint precision when driving on it.

Stationary

Full-size overpasses are of the stationary type. They are installed along highways, on roadsides, and at service stations. The platform is raised high above the ground and allows for a detailed inspection of the car from the bottom and for carrying out repair work. Designed to support the weight of cars and trucks.

The strongest and most durable structure is made of metal. To create an observation deck, brick, wood, pipes and channel are used.

Advice! If the garage is built for 2 cars, but there is only one there, then the free space can be allocated for your own overpass.

Collapsible

The collapsible overpass has smaller dimensions. It fits easily in the garage and, if necessary, is quickly assembled. Designed for inspection of a passenger car.

The design includes:

4 stands for supports;
2 pairs of platforms with a stopper to prevent the car from rolling away;
2 pairs of horizontal ramps for inclined access;
several stiffening ribs for fixing parts relative to each other.

They are built from metal. The thicker and more durable the material chosen, the longer the structure will last.

General requirements

Making an overpass is not a complicated process, but you need to remember a few nuances:

The height of the full-size version is up to 1 meter, and the mini version allows you to raise the car by 0.3-0.7 meters.
The width of the structures is determined by the width of the vehicle. To make it easy to access, the ramps and platforms are made 0.4 meters wide. These dimensions are sufficient for most wheels.
The safety margin determines the service life. In the mini model it is not so critical, and when building a stationary overpass they do not skimp on materials.

The overpass, assembled independently, should fit in ordinary garages. When creating a drawing, take into account how much there is free space for storing it.

Stages of preparatory work

Carrying out the work yourself, from the design stage to final assembly, is not difficult. To do this, you need to decide on the type of design that you prefer and available material, make a drawing, calculate the dimensions and number of parts, make an estimate for the purchase of materials, rental of equipment.

Calculation of dimensions and drawing up drawings

Start creating a drawing by selecting the type (stationary or portable) and material. Each person will have their own preferred shape of the product. General dimensions:

height – up to 1 meter;
width – about 0.4 meters;
lifting length – about 1 meter;
the length of the flat platform is from 0.3 meters.

An overpass is a pair of identical structures. On the side of the diagram, its shape resembles rectangular trapezoid. A pair of slides can be additionally fixed between each other to avoid displacement while the machine is being lifted onto it.

Preparation of materials and tools

Depending on the material, tools are selected for the overpass. A structure made of sleepers or metal is assembled using:

welding machine;
Bulgarians;
bolts, nuts.

The main material is reinforcement and a 40 mm corner. The finished structure is coated with anti-corrosion paint on top.

A wooden overpass is created from:

wooden blocks with a square cross-section with a side of 0.2 meters;
wooden blocks or boards;
nails, screws;
saws;
screwdrivers.

DIY metal structure

The most popular is a mini overpass made of metal. This product has a number of advantages:

easy to move;
ease of assembly - does not require special skills;
reliability and durability.

Although a do-it-yourself overpass can last for decades, over time any structure wears out. If you properly care for it and treat it against rust, its service life will increase significantly.

Welding of the structure proceeds as follows:

a corner is cut and two rectangular trapezoids are assembled;
connect them together with a corner;
using scraps and remnants of the corner on the sides, additional stiffening ribs are formed;
the reinforcement is cut and welded onto the upper base and inclined plane;
clearing out wire brush, painted with metal paint.

The procedure is repeated for the second part of the trestle pair. You can make a limiting side on the upper platform to prevent the car from passing further. It is convenient to store it vertically.

Instructions for making a wooden mini trestle

Wooden construction is characterized by low cost of materials. The advantages also include:

simplicity of design. It does not require special tools and equipment; it can be made using available materials;
the mobile overpass has a relatively light weight;
mobility - easy to set up and remove.

The disadvantages include a small margin of safety. Over time, the timber overpass will rot and be undermined by insects. Special treatment will help increase service life.

There are two types of portable wooden overpass:

One piece. Take a beam with a cross-sectional side of at least 0.2 meters. Connect it with nails to another cut. A bevel is cut off from one edge. The height of such an overpass is small, but it is lightweight and can be stored in the trunk of a car.
Stepped. It is created from blocks and 50 mm boards. The pads are cut into pieces. Depending on the height, some are cut off from one edge. The structure is assembled in layers: a board, on it, with a certain step, several blocks are nailed, and again the board. Each tier is shorter than the previous one. Stops at the required height. A motion limiter block must be placed on top. The smaller the angle of inclination, the easier it is for the car to drive. But this lengthens the overpass and makes it heavier.

Technology for creating a brick structure

A type of stationary structure is a brick product. For construction it is necessary to allocate a plot of land. A homemade overpass is no different in shape from metal or wood. All parts are built from brick.

The construction method includes the creation of a classic brickwork on cement mortar. The advantage of this automotive alternative to the inspection pit is its strength. It can withstand the weight of even a truck.

The disadvantages include:

the need to allocate a sufficiently large plot of land for it;
installation, as well as dismantling, requires a lot of time;
Over time, the masonry collapses and requires its hollow demolition.

Such a structure is more suitable for garages in villages and outside the city, where there is a lot of free space. The brick is chosen to be as durable as possible. Construction work better to spend in warm time year.

Landscaping of a personal plot can be considered complete if, for the “complete set,” an overpass for car repairs is independently constructed. The dizzying designs of overpasses amaze with their brevity and the ability to use the simplest metal products. Do you dream of making a flyover with your own hands? What could be more exciting!

“Personal car service” services

Almost every homeowner dreams of having their own personal plot attractive, practical and functional. And if the homeowner is also a passionate car enthusiast, then it’s simply impossible to do without an overpass designed for on-site car repairs.

Even if you do not plan to service the car yourself, periodic inspection will help you identify problems in a timely manner and contact a professional workshop. To access the car, use special lifts, an inspection pit and an overpass. However, expensive special equipment and an inspection pit equipped according to all the rules are strictly the prerogative of service centers, which require significant material costs.

An overpass for a car, on the contrary, can be installed anywhere on the site, almost next to the potato beds, and mind you, with your own hands. You can make a car overpass for cars and trucks. The scope of use and application of such an overpass can be expanded and it will be possible to use the services of a “personal car service” at any time of the day or year.

Overpass structures

Structurally distinguish the following types overpasses:
for partial car check-in
full-size overpass.

Naturally, depending on the size of the overpass structure and bearing capacity to withstand the load, these types of overpasses are used for a certain weight of cars. The only condition will be to limit the size of the overpass for your existing passenger car or two.
The classic design of an overpass (practically from the words of a driving instructor) has a certain height, width and length of the working part, limited by a bevel, as well as on the sides of the walkway.

overpass designed for partial entry of cars

The overpass for partial entry of cars (portable and mini) is a lightweight portable structure consisting of separate parts that are not welded together. Portable and mini overpasses are installed without a foundation. Access to this overpass for subsequent vehicle inspection is possible with front or rear wheels.

This type of overpass for cars is easy to install and also easy to remove, allowing you to save space on the site. However, for a successful ride on the structure, the driver’s dexterity and dexterity will be required.
Main parameters of the overpass:
height – at least 1 m.
width – 2.5 m.
bevel length – 4.2 m.
Structurally, a portable or mini overpass consists of four parts.

The overpass is easily assembled and disassembled, and also transported to the required location, so for the sudden diagnosis of a capricious car, such an overpass is indispensable, especially in “field conditions”. In practice, sometimes it is necessary to make two overpasses to raise the front or rear of the car to required height(clearance plus overpass height).

This is what a self-made overpass looks like, used for a partial drive-in.

full-size overpass

Of course, a full-size overpass is a more convenient and reliable structure, the construction of which requires workspace. But a full-size overpass will more than recoup the costs of its construction in the future.

The main parameters of a full-size overpass are similar to the parameters of portable and mini overpasses:
height – 1 m or more
width up to 2.5 m.
length of the working part – 4-6 m.
the length of the bevels on both sides is 4.2 m.
Let’s make a reservation right away that the dimensions of a full-size overpass for passenger cars are not a constant value.

Therefore, a full-size overpass is made taking into account the safety margin and additional allowances, which will serve well in the future. In addition, a full-size overpass can be successfully used as an inspection overpass for a car by equipping an inspection hole.

How to make a car overpass with your own hands

Theoretically, you can make an overpass for a car from any available material. The materials used are boards, bricks and used tires. But such temporary measures can only be justified in extreme cases.

Therefore, for the main load-bearing elements and overpass tracks use rolled metal that can withstand significant daily loads. This is a metal channel, corners and a profile pipe. These types of rolled metal can withstand significant bending loads.

how to make a mini overpass

To make a mini overpass you will need the following materials:
steel corner, thickness not less than 10 mm
metal rod.
as well as electrodes for welding and a welding machine. We choose the shape of the mini overpass supports as a “trapezoid”, with the base 15-20 cm larger than the top. The access ladder is made of steel corners, onto which pieces of rod are evenly welded on both sides.

It is preferable to choose a corrugated surface of the rod so that the car wheels do not slip when going up and down the overpass.

The load-bearing elements of the overpass on which the ladder is attached must have a width of 45-50 cm. The car is secured with special gaskets that prevent the car from unintentionally moving out. After welding, the overpass structure is painted with anti-corrosion paint.

A mini overpass for car repairs is presented in this video.

how to make a full-size overpass

Initially, a site is selected on the site where there is no swelling of the soil, groundwater and soils do not have a water-saturated layer. Prepare holes for the base of the overpass - pillars or steel pipes with a diameter of up to 10 cm.

The number of pipes for the base of a full-size overpass is calculated based on a preliminary working sketch. Pits with installed pipes are cemented. A channel is welded to the installed pipes or poles to enhance the load-bearing capacity.
It is also recommended to use rolled metal (channels, angles and profile pipes) as load-bearing elements for walkways. Then the rolling plane is made: reinforcement and cut rods are welded across the load-bearing elements on both sides.

The width of the rolling plane path must be at least 0.5 m. The resulting welded structure is placed on special supports of the required height (1 meter). To make the drive-in platform and stairs, use an L 50 corner welded with reinforcement. It is preferable to protect the edges of the paths with a corner, preventing the car from slipping.

Every car enthusiast should ideally have an overpass. This structure is necessary because a car is not always a means of transportation - in some cases it may require repairs. That is, the driver will have to perform many different actions: lie down on the floor, inspect the bottom of the car, etc. When performing this work, you will have to be under the vehicle, which is not very convenient. To simplify the task, it is worth thinking about building an overpass.

How to make an overpass

In order to construct such an important structure for repair on your own, you must first acquire necessary products: special bridges, supports for them. You will also need bricks, sleepers, and cement. It is no secret that an overpass is a structure that can be of various types.

First, let's look at a portable overpass. It is not difficult to build - you need to find unnecessary (possibly old) bridges for the overpass (two are needed). The height of these supports should be about 50 cm. The length of the bridge is usually equal to a meter (or a little more). You will need two of them. The length of the second should be 40 cm. These parts are connected by means of hinges - they are represented by a finger rod. This method is perfect for organizing an overpass - a practical and durable structure that is very easy to disassemble if necessary. When the car repair work is completely completed, it can be easily put aside.

Inspection pit - an alternative to an overpass

We are talking about a standard, well-known way to organize overpasses for car repairs. They make a hole, the size of which is approximately the same (they also take into account the additional distance in width so that the working conditions are comfortable). To put it simply: the length of the pit depends entirely on the dimensions of the machine. Its walls and bottom must be covered concrete mortar. This ensures protection from moisture and dirt. You can use modern waterproofing materials - this will also help avoid problems during operation.

Before constructing an inspection hole, you should definitely check how they are located and where they lie. If they still exist, it is better to refuse to build a pit - there are plenty of practical overpass structures without this. It is imperative to remember to strengthen the walls of the pit - otherwise, collapse may always occur. To make access to the pit convenient for inspecting the bottom of the machine, a ladder should be built. When no work is being done, everything is covered with slate (or some other material).

using a brick structure

Such an overpass is a structure for the manufacture of which the most ordinary bricks are used. They are connected into an arched single installation, the width and length of which must correspond to the parameters of the car. Then they cement what happened. There is one drawback that needs to be taken into account - after some time, the cement may begin to crumble. It is better to prevent this phenomenon in time. However, this overpass for a car is quite appropriate somewhere in the garden or on the territory of a summer cottage - anyway, a better solution usually cannot be found there. You can build something else in the courtyard of the house; a brick option is unlikely to be appropriate.

Construction of an overpass using sleepers

The most simple options we discussed above. The time has come to describe a serious means - an overpass made of sleepers. This design is highly durable. For its construction you only need one thing - railway sleepers. Before construction, this material is necessarily impregnated with creosote - a special substance that is necessary to prevent various negative phenomena: the appearance of fungi, the development of rotting processes. Thanks to impregnation, the car overpass will last much longer.

So, to carry out construction, you need to have several sleepers. They are usually laid out on some hill prepared in advance, or made directly from the elements. It is important that it be about 500 cm in length and at least 260 cm in width. Several people must participate in the construction at once - individual elements are quite heavy. The weight of the whole structure will be much greater - it will not be possible to lift it alone.

Types of overpasses

All car overpasses can be divided into two large categories - only for lifting some part of the car and for a full drive. It all depends on the ability to withstand the load, on the overall dimensions of the structure. A durable overpass is a device where a channel is used as load-bearing elements. These types of rolled metal can withstand very high bending loads - they are usually laid along the rolling direction. Before construction, the standard size of all load-bearing elements is determined. It is also important to make a certain margin of safety before erecting the structure.

If you don’t have an inspection hole for your car, you can replace it with a flyover you made yourself in the garage or at your dacha. To do this you will need a couple of sleepers and a few thick boards or some scrap metal, a welding machine and a grinder. Of course, a pit in a garage is more convenient, but for various reasons not every garage can be equipped with one. The proximity of underground communications or groundwater can interfere, and then, if you want to repair your personal car, the solution for you will be to build an overpass with your own hands.

Types of overpasses

Depending on the size, there are two types of overpasses for cars:

For access to one vehicle axle.
For entry of the entire car.

There are two types of devices that provide access to both the front and rear of the machine:

Installed on level ground. Entry to their site for repairs occurs at best at an angle of about 30° to the horizontal.
Located on a slope. Entry to them occurs without climbing up (horizontally).

For those wishing to make a mini overpass for car repairs with their own hands, we present a simple design that does not require drawings to replicate.

To work under the car on such an overpass, be sure to get a piece of thick felt or at least an old cotton blanket. Don't leave your health on the concrete floor.

Full size design

Metal installation

Two steel pipes with a diameter of at least 150 mm can be used as supports. They should be buried in the ground below its freezing level, otherwise the height of the overpass with the onset of winter will increase and decrease in the spring. After installing the supports, the pits should be compacted with broken bricks, or better yet, concreted. If the depth of soil freezing in your area is small, bury the supports into the ground at least a meter. The height of the supports above the ground depends on your height, but should not be lower than 1.5 meters.

They should be installed at a distance of about 5 meters from the intended entrance to the overpass, and at a distance from each other equal to the track of your car. Place a piece of channel about 150 mm wide on top of the supports, edges down; its length should be 50 cm greater than the track width of your car. Weld the channel to the supports. After this, for lateral stability of the structure, connect the supports crosswise with two corners. Place four corners with ribs of at least 7.5 cm and a length of about 5 m in pairs parallel with the ribs facing each other, and fill the space between each pair with pieces of reinforcement 50 cm long and weld them to each, maintaining a right angle. Lay the resulting ladders so that one side of each is on the edge of the channel, and the other on the ground. Check their horizontalness using a level. And also set the width between the centers of the edges lying on the ground, which should be equal to the track of your car. Weld them to the channel, and to them stops that prevent the vehicle from falling, and congratulations, you have welded a steel overpass with your own hands.

Features of a wooden structure

Instead of a pipe, two pieces of timber with a cross-section of at least 15 × 15 cm are used as supports.
Parts of supports dug into the ground must be impregnated with creosote or at least mining for durability.
Each ladder should be assembled from two boards 5 cm thick, one of them 10 to 15 cm wide should be placed on its edge. Place the other one, about 40 cm wide, flat on top and nail it to the first one with nails or screw it with screws.
In each beam it is necessary to make one cut 5 cm wide and deep in accordance with the width of the boards placed on edge. The cuts are made in order to insert the lower boards of the ladders into them. The crossbar should be attached to the supports not from the top at the ends, but from the front, just below the ladder board coming out of the cut.
The supports can be made by screwing two pieces of block wood onto the supports with self-tapping screws, so that they stick out above the ladders.
To reduce the likelihood of wheels slipping from the edges of the ramps, it is advisable to make ribs. One option is to attach a board about 2 cm thick and 10 cm wide to the end of the top board of the ladder. It is better to fasten it with self-tapping screws with flat heads 50 mm long.
Below the crossbar, for lateral stability of the structure, the supports must be fastened together crosswise with two boards.

The overpass is an indispensable tool for inspecting and repairing a passenger car. A small mini-structure is made at home with my own hands. It is important to observe all dimensions and focus on the dimensions of your car.

The need to install a mini-overpass. Device

A modern car is a technically complex device that requires periodic maintenance, replacement of components and consumables, minor repairs. Many inexperienced motorists prefer to carry out a routine inspection of the car exclusively at a service station and pay out of pocket even for an oil change.

More experienced drivers do most of the work themselves. To do this, a homemade overpass is often installed in the garage - a structure with which you can examine the bottom of the car.

There are two types of overpasses:

To a first approximation, the functions of the overpass are similar to the inspection pit. It provides access to the underside of the car. However, when high level Given the occurrence of groundwater at the site where the garage is being built, it is not advisable to equip an inspection hole: it will constantly be filled with water, which will require additional equipment drainage system, and on metal parts Cars will experience corrosion due to increased moisture.

A full-size overpass is a monolithic structure that can be found in auto repair shops and along busy highways. Its installation requires a lot of space - the length of the product is about six meters above the ground plus the driveway. The construction of such an option in your own private garage is justified if the building is designed for two parking spaces, one of which is empty.

Mini overpass - small portable design, designed for partial collision with a car. It is based on two independent parts that are not connected to each other. The car drives onto the prepared platform with its rear or front wheels, rises slightly above the floor or ground and allows the car owner to carry out an initial inspection or cosmetic repairs.

The advantage of a mini-overpass is the possibility of its use in limited space. After work it can be put aside. The main disadvantages of the design are as follows:

To enter the platform, pinpoint precision is required. Otherwise, the structure may overturn or the vehicle may be damaged.
Structural elements are installed in places where there is no possibility that they will diverge in different directions from the slightest push of the wheels.

General requirements

When manufacturing a standard overpass, a number of requirements must be met. This will help ensure comfortable and safe work with a car.

The height of the full-size repair structure is about a meter. This allows you to easily climb under the car and ensure sufficient inflow natural light to inspect the chassis, carry out the necessary manipulations with spare parts and tools. The height of the mini-overpass with partial access is about half a meter: it does not involve detailed disassembly of the car.
The width of the structure directly depends on the type and dimensions of the vehicle. You should not display the size down to the millimeter; when calculating the design, you need to make small allowances. The car must drive onto the platform without hindrance.
Mini-overpasses are used for inspection and repair of passenger cars. For a stationary structure, an additional margin of safety is provided. Thanks to this, the product does not deform over time. You can also roll fairly heavy vehicles onto it.

Material selection

There are many ways to make a do-it-yourself overpass or mini overpass for car repairs.

Brick construction

A brick overpass is a stationary structure, which is more often used in rural areas or outside the city. Construction is carried out using the bricklaying method using cement mortar. The width of the structure corresponds to the distance between the wheels of the car.

This method has a number of disadvantages:

It is necessary to allocate a plot of land for development. If the overpass subsequently needs to be removed, its dismantling will require considerable effort and time.
After some time, under the influence of overloads, the brickwork may collapse, which may require its dismantling.

Overpass made of sleepers

The structure is based on several railway sleepers. The sleepers laid one on top of the other in a “slide” style form two bases. Tracks are laid across to ensure access. To prevent the sleeper trestle from moving apart during operation, it is carefully secured with brackets.

This design also has certain disadvantages.

Sleepers are not so common in everyday life, and not every car owner has a few extra ones.
It is impossible to install and disassemble such an installation alone. The sleepers are too heavy.
Storage of railroad ties requires space.

The use of a trestle made of railway sleepers is justified in a country house or garden plot, when the structure is left outdoors all year round. To protect against rotting, the product is impregnated with creosote.

Made of metal

Most often, the overpass is made of metal and wooden planks. Advantages of a metal overpass:

Mobility. If desired, the structure can be made collapsible and assembled only before starting repairs. This saves space.
Simplicity of design. You can assemble a metal overpass with your own hands using a minimum of tools.
Durability. With proper care and timely inspection, a metal trestle can last about ten years or more.

There are also some disadvantages. The metal is initially susceptible to corrosion, so before work the material must be treated with special impregnations.

Among the main advantages of a wooden trestle are the ease of assembly and low cost of materials. It is easy to install and, if necessary, can be quickly dismantled and removed. You do not need complex specialized equipment; ordinary carpentry tools that are found in every home are sufficient. Among the disadvantages of wooden structures are low durability and poor resistance to rot and insects. These problems can be partially solved by treating with antiseptics, fire retardants and insecticides.

Tools and materials

Independent production of a wooden or metal overpass requires the availability certain materials and tools. There is no need to purchase complex specialized equipment; it is enough to purchase household power tools, which are sold in every store.

What is needed to build a metal overpass

To make a regular metal overpass, you will need the following materials and tools:

Rolled metal.
Welding machine with a set of electrodes.
Grinder equipped with several cutting wheels.
Pieces of reinforcement.
Fasteners: bolts, nuts.
Metal paint for finishing the structure.

Materials and tools for a wooden overpass

To make the simplest portable wooden trestle you will need a minimum of materials and tools:

Boards 45–50 millimeters thick. If thinner boards are used, additional vertical supports are installed in the center of the overpass.
Two wooden blocks.
Two pieces of carriage plank.
Screws (150), nails (300), screwdrivers, hammer, wood saw.

Preparing for work and drawing up a drawing

Before making the overpass, it is necessary to carry out a number of measuring works. The mini-overpass consists of two independent installations. The width of each of them corresponds to a car wheel with a small margin. The gap between installations is equal to the distance between the wheels of the car. At this stage, tools, materials and work site are prepared.

All dimensions are approximate and calculated for each car model

DIY metal structure

If a metal overpass is planned to be used in several places, or is needed only occasionally, the structure can be made in a collapsible version. This will allow you to quickly assemble it as needed within half an hour.

The assembly of a metal overpass occurs as follows:

The finished structure is cleaned with a metal brush, degreased and painted.

The finished design will look something like this

Making a wooden mini-overpass

The simplest wooden overpass assembled from two pairs wooden beams with a cross section of 20–20 cm. The beams are knocked together in pairs and cut at an oblique angle. The improvised overpass is ready.

An improved wooden overpass is assembled from scraps of boards, which are assembled into a wide “pyramid shield”. On one side there is a stepped slope for cars to drive in.

Another version of a mini-overpass is assembled from four 50-mm boards, two blocks, lining and fasteners.

A similar design is used for repairing passenger cars. For heavy transport it is worth installing a stationary overpass.

Every car owner can make a mini-overpass on his own. It is very important to check the strength of the structure before driving a car onto it and starting repair work.

A garage overpass is a very popular device. Many car enthusiasts periodically carry out technical inspections and repairs of their personal vehicles.

If visual inspection of the body or some car components can be performed without an overpass, then diagnosing the condition of the bottom and the components located under it is very difficult. This article will tell you how a garage overpass is made.

To carry out high-quality and comfortable repairs and maintenance of your car, it is necessary to properly organize the workplace, especially to ensure its safety for people. For this purpose, a variety of different ones are built, tippers or other devices are purchased.

An inspection hole for car repairs is made in the garage itself or simply in an area that can be:

On a dacha area.
On a personal plot.

When constructing such a structure, in order to strengthen the earthen base, you need to cover the inner layer of the device with bricks or sheath it with boards.

Advice: To make it easier for the driver to work, the descent into the pit should be laid out with steps and handrails should be attached.

A homemade overpass installed in the garage in the absence of an inspection hole also helps to improve the performance of work. Such designs may have different types, configurations and base.

An overpass, most often, is a special device that rises above the ground, serving for periodic inspection of the vehicle and, if necessary, repairs. The purpose of the device is the same as that of the inspection pit.

A homemade overpass is a necessary attribute of any garage. Very often there are circumstances when it is not possible to equip a pit.

This may be related:

With close proximity to groundwater.
Unfavorable soil characteristics.

In this case, making a car overpass will help you easily find a way out of your predicament.

The advantages of the design, compared to a conventional inspection hole, are:

Availability of a larger area for work.
Lots of light.
More convenient.
No dampness.
There is no darkness.
The bridge for cars is not flooded by melt and groundwater.
When performing work there is no need to stay in the ground for a long time.

For a garage, you can use the following options for overpasses:

Portable.
Having the appearance of a viewing hole.
Made of brick.
Constructed from sleepers.

For the manufacture of structures the following is selected:

Wood.
Metal.

Tip: The main feature of a homemade overpass is the presence of a solid base, which allows you to minimize the likelihood of a car falling. To make it, you should only choose quality materials high strength.

The overpass in the garage can be located:

In the corner.
Against the wall. The front of such a structure should be blocked by a fence that will prevent the machine from rolling away.
The overpass can be a kind of continuation of the unhindered movement of the car from the parapet, which requires increasing its length.

Features of overpasses for gates

Based on the listed advantages, car enthusiasts often prefer to use a homemade overpass over conventional inspection pits, which allows them to conveniently solve many problems and repair breakdowns that have occurred in the car.

Structures can be made with bases of varying complexity:

Welded products require special equipment and welding skills.
A simpler device is called a “ladder”, which consists of two small ladders made of wood. The car drives its wheels onto them, and the part needed for inspection rises to a certain height. On such an overpass it is possible to carry out the necessary amount of repair work.

The construction is not so difficult to do on your own. To do this, you will need to prepare boards approximately 50 millimeters thick and square bars 100 millimeters long on each side.

The optimal height of such devices is 15 centimeters, which is enough to complete repair work in full. The portable overpass allows all driver manipulations to be completely safe.

After driving onto the created plane, the car is located in a horizontal position, which ensures the stability of such a structure.

Advice: When on an overpass, the driver needs to be on the safe side: put the car on the handbrake, and put any stop under the wheels that will impede movement.

How to make a flyover from various materials

For car owners in rural areas or who spend a lot of time driving suitable for a dacha a variant of the construction made of brickwork with cement mortar. The design has the form of a trapezoid with a width equal to the distance between the wheels of the car.

Disadvantages of such an overpass:

We need a site for its construction.
Over time, the brick will begin to deteriorate.
To free the site, the structure will need to be dismantled, which will require significant effort and time from the owner.

Overpass made of railway sleepers

The overpass can be assembled from railway sleepers.

In this case, two bases are laid out by laying sleepers on top of each other in the form of a slide, as shown in the photo. Tracks for driving are laid across.

To ensure the reliability of the structure, it is fastened with staples.

Disadvantages of such an overpass:

Not everyone has the required supply of sleepers.
The sleepers are quite heavy, which makes it impossible for one person to assemble and disassemble such a structure.
After the completion of the repair work, you will need a lot of space to store sleepers.

When constructing this structure on your site, they can be left under open air. Wooden sleepers usually impregnated with creosote, which protects the wood from rotting.

Metal overpasses are more popular.

How to make a metal overpass

The metal overpass is universal. It can also be used in city garages.

To make the design you will need:

Rolled metal.
Welding machine.
Any fittings.
Grinder with a set of cutting wheels.
Hardware.
Metal paint

If desired, the overpass can be made collapsible, which will allow it to be quickly assembled if necessary.

The instructions are as follows:

Four base stands are assembled, approximately 50 centimeters high. To ensure stability, the sides should be assembled in the form of a trapezoid and connected to them of the same length with crossbars from an equal angle 63x5. Bridges can be made from a 40x4 corner and reinforcement with a diameter of 12 millimeters. The bridges are an ordinary metal ladder.
Two bridges for driving a car and two bridges for placing a car during repairs are made. The minimum length of the latter is calculated by measuring the distance between the centers of the car's wheels and adding a small allowance to it.
All elements are bolted together, which allows you to quickly assemble or disassemble the structure.

If there is very little space in the garage, you can make a mini-overpass that allows you to partially lift the car, and its price is minimal. To make the most basic version of a mini-overpass, you can use wood or metal.

To work you will need:

Board 50 millimeters thick.
Wooden slats with a cross section of 100x100 millimeters. The lifting height of the vehicle depends on the cross-sectional dimensions.

The order of assembly of the structure:

A block is fixed on the top of the board, which acts as a restriction on the movement of the wheels.
On the other side two are attached wooden bars: one a little further from the middle, the other from the edge of the board.

At least two of these devices are needed, and four elements are needed to lift the entire car off the ground. The operating principle of the overpass is as follows.

When installing the structure under a car wheel, it will rest on the ground at two points:

The front part of the board and a block fixed closer to the middle.
After the car wheel hits the board, the center of gravity will shift closer to the end of the board, its front edge will rise, and the rear part will lower.
Making bars of the same cross-section will allow the board to take a horizontal position.

Tip: The length of the board should be chosen so that it does not hit the bottom of the car.

The wheels remaining on the ground are fixed with special stop blocks.

The video shows in detail what types of overpasses there are and how to make them.

A good help in car repair for its owner will be a do-it-yourself overpass in the garage or next to it. But such a design is bulky and takes up a lot of space, and visiting a service station for minor repairs is not always cost-effective. In the absence of large areas for servicing a personal car, the overpass for car repairs can be made in another version.

How to make a mini-overpass with a partial collision?

The purpose of such a device is to facilitate access to the suspension and underbody of the car. In this case, only the front or rear pair of wheels is raised to a small height above the ground. During inspection and repair, stops must be placed under the other to prevent accidental rolling off an inclined surface.

The simplest option for making an overpass is ladders. To make them wood will do or metal thick enough to support the weight of the machine. You will need:

board at least 5 cm thick or metal corner 4x4 4-5 mm thick;
timber (thickness depends on the height to which it is convenient to raise the car);
grinder and welding machine for working with metal;
saw, nails for working with wood;
roulette.

To make it, you need to calculate the length of the board or metal bridge for the wheels to run over so that, when positioned horizontally, this part does not damage the bottom of the car. Making wooden ladders comes down to sawing off 4 pieces of timber for the base and a board for the bridge. The width of the bridge must be sufficient for the wheels to move freely (at least 30-35 cm). Nail the pieces of timber to the boards in the position shown in the figure: in the middle of the ladder and at its edge.

When making a bridge from metal, you need to cut off a corner with a length equal to the estimated length of the bridge (4 pcs.). Connect these parts in pairs with short sections of the same angle or reinforcing bar 15-17 mm in diameter. The resulting “ladders” are able to withstand the weight of a passenger car. On the lower side of the bridges, weld the base from the corner in the form of a U-shaped structure. The height of the base is selected individually. The base posts should be positioned in the same way as in wooden structure. When hitting the ramp up to the first support of the base, under the weight of the car, the automobile overpass comes to a horizontal position, and its rear part rests on the second support of the base.

There is another option for a mini-overpass. These are 2 small home-made welded structures from a 4x4 corner 5 mm thick in the form of a fixed bridge with inclined entries for lifting one pair of wheels. The length, height and width of each part can be calculated individually, depending on the make of the car. During manufacturing, it is necessary to weld 4 rectangular frames from a corner, connecting them in pairs with crossbars at the bottom. Weld onto the top part pieces of rod or angle along the width of the bridge.

The inclined entrances are welded in the form of “ladders” supported by the front part of the horizontal bridge. Relatively light metal structure Can be stored in the garage without taking up much space. If necessary, it can be quickly installed at any suitable site for inspecting the machine.

Full collision with an overpass

This portable design means that the car will be in a horizontal position at a certain height above the ground. This provides greater comfort during preventive and repair work the owner of the car.

The distance from the surface of the site to the bottom can reach 1 m or more. As an example of how to make an overpass, you can use the drawings in Fig. 3 or develop your own. You will need:

steel corner 5x5 cm, thickness 10 mm;
reinforcing bar with a diameter of 17 mm;
Bulgarian;
welding machine, electrodes;
roulette.

Cut the corner for the supporting structures according to the dimensions indicated in the diagram. Cuts for outside each support should be 10 cm longer than those that will be under the bottom of the machine when the collapsible mini overpass is installed in its working position. This will provide support for the bridges and wheels of the car, preventing their possible drift to the side. 2 supports must also be equipped with transverse stops for wheels at the point farthest from the entrance to the overpass.

Weld 2 trapezoidal structures for each support: with and without the ends of the corner extending above its upper edge. Connect the trapezoids with crossbars about 60 cm long, welding them in the corners of the structures. Having assembled 4 supports, make transverse supports on those that will be installed at the far ends of the overpass.

The length of the bridges and entry inclined parts is determined by personal needs, depending on the size of the car. Their width should be sufficient for convenient passage of the machine on an inclined and horizontal surfaces. The bridges need to be welded in the form of “ladders”, connecting the sections of the corner with crossbars of the required length from a rod.

To ensure the reliability of the prefabricated structure, it is necessary to provide holes for fastening with bolts and nuts at the intersections of the bridges with the upper parts of the supports and at the points of attachment of inclined entrances to them. To bring the overpass into working condition, it is enough to install 4 supports, lay horizontal bridges and install inclined ramps for lifting the car. After completing the inspection and repair, the homemade mini-overpass can just as easily be disassembled into its component parts and can be stored without taking up much space in or near the garage.

With little skill in working with welding machine and a metal overpass can be made with your own hands in about a week. The convenient and space-saving design will last for decades. With approximately the same parameters of passenger cars different models it will come in handy when the owner himself changes the car, and for helping a friend if necessary.
