Make an overpass in the garage from a car. Assembling a mini-overpass with your own hands: wooden and metal. Main types of road overpasses

If you own your own car and garage, but prefer to at least occasionally look under your car yourself, then the following is for you. Typically, inexperienced drivers prefer to carry out inspections only at service stations and give their hard-earned money to “specialists”, but even carrying out minor work on changing oil, consumables, monitoring the condition of the units and mechanisms of your car can save your budget. A do-it-yourself overpass made in a garage is the best way out of this situation.

Let's look at the statistics of a survey on the topic of whether it is difficult to make an overpass in a garage with your own hands. 66% of respondents answered that it is quite simple; 14% believe that it is simple, but with minor problems; 16% said it is not easy and will require skills in this area; for 4% this is a very difficult task.

Depending on the size of the garage and the model of the car, you can choose an overpass option that will meet your needs.

Overpasses can be divided into 2 types:

for full vehicle entry;
for partial lifting of the vehicle.

The first type will provide more comfortable conditions car maintenance work than the second.

Overpass options for full vehicle entry

Such a statement will be correct from the point of view of the meaning of this word. But the function of the pit is the same as that of the overpass - to provide access to the bottom of the car.

The advantage of the pit is that it will not take up useful space in the garage.

If the level groundwater in the area where your garage is located, it is high, then it is not advisable to consider the issue of an inspection hole.

Otherwise, you will have to make an additional drainage system (which is very troublesome and expensive), and the bottom of your car will be subject to constant corrosion due to moisture that will collect in the hole.

As a result, you will have to fill it up and consider other options.

Brick overpass

This option is suitable for those who have a garage in a rural area or in the country. This design is made by conventional brick laying on cement mortar– along the width of the distance between the wheels of the car in the form of a trapezoid.

The disadvantages of this type of overpass are obvious: a site is required for its construction; brick may deteriorate over time; If you need to vacate the site, dismantling the structure will require significant effort and time from you.

Overpass made of railway sleepers

This overpass is assembled from several railway sleepers, like a children's construction set.

You can lay out 2 bases by stacking sleepers one on top of the other in the form of a slide. Lay tracks across for driving.

To prevent the structure from moving apart during the repair of your car, it must be secured with staples. The disadvantages of this overpass are obvious.

Firstly, not everyone has sleepers in stock. Secondly, sleepers are very heavy; it would be impossible for one person to assemble and disassemble such a structure. Thirdly, after performing automobile repair work you need a lot of space to store sleepers.

Of course, if you are building this design on garden plot, you can leave them under open air. Sleepers are usually impregnated with creosote, which protects the wood from rotting.

Metal version

If the previous options are possible subject to availability land plot, then the metal overpass can be considered as universal - it can also be used in urban environments.

To make it you will need the following tools and materials:

rolled metal;
welding machine;
fittings;
grinder with cutting wheels;
bolts with nuts;
metal paint.

If desired, you can make the overpass collapsible. This will save space by quickly assembling it when necessary.

Its design is quite simple. It is necessary to assemble 4 base posts with a height of approximately 50 cm. To ensure stability, it is better to assemble the sides in the shape of a trapezoid and connect them with crossbars of the same length.

A 63 corner (5 mm thick) is suitable for this. To make bridges, you can use 40 angles (4 mm thick) and reinforcement (12 mm is suitable).

The bridges are a metal ladder. It will be necessary to make 2 bridges for driving in and 2 bridges on which the car will stand during repairs. You can calculate the minimum length of the latter yourself by measuring the distance between the centers of the wheels of your car and adding a small allowance.

After the individual elements are ready, they need to be bolted together. In order to provide additional rigidity to the entire structure, the racks can be combined with each other. The bolted connection will allow short terms assemble or disassemble the entire structure.

Construction of an overpass for a garage

If there is a complete shortage of space, a way out of the situation can be found in the manufacture of mini-overpasses. They refer to overpasses for partial lifting of a car. Of course, working in this case will be less comfortable than with the options discussed above, but much more convenient than under a jacked-up car.

Several options for mini-overpasses

The most basic version of a mini-overpass can be made of wood.

To do this, you will need a board (you can take it 50 mm thick), which is wider than the wheels, and a square wooden strip (for example, 100x100 mm). From height cross section will depend on how high the car can rise. With the parameters recommended above wooden products the lifting height will be 150 mm.

The structure is assembled as follows.

A block is attached to the top of the back of the board, which will serve as a limiting wheel travel. 2 square-section slats are attached to the bottom: one is slightly further from the middle, the second is on the edge of the board. The structure is ready.
You need at least 2 such devices (or 4 if you need to lift the entire car off the ground). This mini-overpass works very simply. When you place the structure under the wheel of your car, it rests on the ground at 2 points: the front edge of the board and a block that is secured near the middle.
Once the car's wheels hit the board and the center of gravity moves closer to the rear edge of the board, the front edge will rise and the rear will lower. Since the supports were made of a block with the same cross-section, the board will take a horizontal position.
In this case, the length of the board should be such as to prevent it from hitting the bottom of your car. All that remains is to secure the wheels that remain on the ground with stops and blocks. As you can see, such a flyover is very easy to make with your own hands. You can make a mini-overpass from metal. Its design will resemble the metal overpass discussed above, only in a smaller version. It also consists of supports on which bridges are attached.
It is advisable to weld limiters along the edges of the bridges. This will protect your car from slipping.
One bridge is located at an angle from the ground for entry, the other is horizontal (if you look at the structure from the side, the outline will be a trapezoid). You can focus on the following dimensions: base length – 80 cm; the length for the drive is approximately 45 cm, the width of the bridges is about 40 cm. The entire structure can be assembled from a 25 mm corner (less than that is not recommended). The approximate weight of the structure will be 20-30 kg. A travel limiter for the wheel must be welded at the rear.

More complex, but effective option mini-overpasses can be made according to the swing-rocking principle. To assemble it you will need welding work. It will be necessary to make 2 frames according to the shape isosceles triangle. The width of the frames is selected depending on the width of the wheels of your car, and the length of the bridge is selected depending on the length of the car.

To ensure structural rigidity, the frames must be fastened together. To ensure stability of the structure, it is necessary to use spacer stands under the side that will be above the ground. It should be taken into account that for greater stability the center of gravity of the car should be closer to the apex of the isosceles triangle.

When working on overpasses, you should always remember to follow safety measures. The car must be put on the hand brake and the wheels must be secured with chocks.

Let's summarize. Have you considered various options and approaches to how you can make an overpass with your own hands. Depending on what you have at your disposal free space, materials, finances and desires, you can choose any option for your garage.

This can be either a solid structure or a collapsible version of a metal overpass. Perhaps it will be enough for you to make a wooden mini-overpass. In any case, the choice will be yours.

I decided to make a portable and simple overpass with my own hands. A little time and our overpass is ready, I won’t describe much, so everything is almost clear from the photos.

For work we will need:

Welding machine - 1 piece
Bulgarian - 1 piece
Roulette - 1 piece
Square - 1 piece
Marker (preferably white, great for drawing on rusty corners)) - 1 pc.
Clamp - 2 pcs
Electrodes - 2kg
Cutting discs - 4 pcs
Metal corner 50x50
Metal corner 25x25
Fittings 10″

Well, let's dive deeper:

The base is 165 cm long, 50 cm wide and 45 cm high. It consists of two 165 cm corners and three 40 cm lintels.

We connect this whole thing strictly perpendicularly at the distance we need: two jumpers at the edges, they form a complete support spot, and the middle one is at a distance of 50 cm from the extreme one, so we get the support of a horizontal parking spot.

Next, we need to place 2 more corners, already 40 cm long, perpendicularly, we form a “stopper”, the border of the overpass, so that the car does not pass the “point of no return”. At the same time, we immediately mark the parallel of the first 30 centimeter supports for subsequent horizontal connections.

Then, using a corner 117 cm long, we make a slope (115 cm long + 2 cm overlap on the nickel)

The first (concept) overpass on one side is ready. I made it without sketches or drawings, so to speak, out of my head, supplementing, redoing and working on it as I went along. We make the second one the same way... And that’s it, our overpass is ready.

So I decided to make a mini overpass from scrap wood, or rather from pieces of board that I had left. The thing is needed in the garage and can be done in a couple of hours.

So, I think there is no need to describe much, everything is practically clear from the photographs. The overpass turned out to be convenient, does not take up much space during storage, which is also important, and is made from a simple board.

The width of my board was 20 cm, so the overpass turned out to be of this size.

Accordingly, I first sawed pieces of this size, 6 pieces on each side, resulting in a total of 12 such blanks.

Then I drilled them all the way through and screwed them together with 12mm studs.

I did the first fitting, what distance will I have... it turned out to be 45 pure centimeters, I think not bad, just right for my needs.

Then it was necessary to make stops at the ends so as not to drive over the overpass :)

Here's what happened:

The storage of this craft is generally great; it takes up space purely symbolically.

This is how it turned out to be the right thing in the garage, now you don’t have to struggle and put the jack up every time, but just take it, drive it and you’re done. I think someone will like this idea and have a smooth road for everyone.

DIY mini overpass (17 photos)

Do-it-yourself mini overpass for a car: photo, as well as manufacturing description, a simple and practical overpass.

I decided to make myself a device for working under a car, a mini overpass with a height of 370 mm.

Materials for production:

Square pipe with a cross section of 50 x 50 mm, wall thickness - 4 mm.
Square pipe - 40 x 40 mm, wall thickness - 2 mm.
Round pipe - 25 mm.
Corner 65th 5 mm.

I made the middle paws shorter than the outer paws by about 8 millimeters, so that there would be no swing. When the entire mass of the machine presses on the structure, the difference is leveled out. The load is distributed evenly across the thrust feet and there is no wobbling.

The device has been tested.

The angle of entry is too blunt to drive in with a belly rub; it will be possible to weld an additional ladder that will lie on top of the main ladder.

How to make a flyover with your own hands, for a car, from wood and metal

How to make a flyover with your own hands

Individual owners in many cases carry out maintenance and repairs themselves in various places depending on existing conditions (in individual garages, in personal gardens, summer cottages, in open areas, along the route, etc.). In this article I will tell you how to make a do-it-yourself overpass for car repairs.

In any case, you need to organize workplace overpasses for carrying out work, taking into account the creation of the safest and most favorable conditions to carry them out. Inspection ditches and tippers serve these purposes. Overpass inspection ditches can be made in individual garages or open ground on personal, country, garden plots. To prevent the earth from crumbling, the inside of the ditch is reinforced with a brick wall or lined with boards. To enter the ditch, make brick steps or a wooden ladder. It is necessary to constantly ensure that the steps are not slippery to avoid falling into the ditch.

The overpass that you can make with your own hands can be metal or wood, but its strength and rigidity should prevent the car from falling. Depending on the wishes of the individual owner and local conditions, this platform for the car can be a dead-end, when the car drives in and out of it on one side, or have an independent exit on the other side, while the total length of the overpass must be increased. The end of the dead-end road must have a fence to prevent the machine from falling.

The edges of the ditch of the overpass for cars should rise slightly above the level of the floor, ground (for the ditch) or the plane of movement of the wheels in order to prevent the possibility of the car falling during installation or exit on them (safety flanges 10-15 cm high are provided).

The length of the ditch is chosen so that a car installed on the ditch in the overpass does not cover entrance staircase. The width of the overpass for cars is determined by the track of the car, taking into account the safety flanges (1.0-1.1 m). The length of the horizontal part of any type of overpass must be such that your entire unit can be installed on it.

Overpass ditch depth

The depth of the ditch and the height are determined depending on the height of the worker so that when performing work you do not reach for the bottom of the machine or constantly be under it in a bent position.

In addition to the ditch or overpass and regardless of their presence, a stable workbench or work table must be installed, strong and rigid enough so that a vice can be installed on it to perform metalwork work on repairing individual units and components.

The height of the workbench or work table should ensure a comfortable position for the worker. The width must be at least 0.75 m. The boards of the workbench or work table must be planed cleanly, and the nails must be recessed to avoid injury to the hands. A workbench or work table can be upholstered in iron. In this case, there should be no sharp edges or protrusions that could cause injury.

The vice must be firmly secured to the workbench or work table. This is one of the conditions for preventing injuries during work. hand tools. The jaws of the vice must have a notch and ensure reliable fastening of the part. The part must be secured in a vice so that it does not jump out during processing.

Lamps should be installed above the workbench or work table in the garage so that the light falls from the left side, and the illumination of the workplace using incandescent lamps with combined lighting (general and local) should be 400 lux. The actual illumination is measured with a portable lux meter. On the workbench, the tool must be laid out in an order that is convenient for work and in such a way that there is no possibility of it falling and causing injury. Tools can be placed on permanent shelves or hung on garage walls subject to the above conditions. We hope that our website useful tips for all occasions I helped you make the overpass yourself.

how and from what to make

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.

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 not to fall 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 a car can be raised to such a height with a jack, 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 be at least 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.

DIY portable overpass

Scheme of a homemade overpass (car):

The overpass drawings were made specifically for the VAZ car of the tenth family. Therefore, the dimensions of the overpass (distance between lanes and length) for other vehicles may differ.

To build an overpass you will need:

The structure of the overpass is quite simple, and if you have the necessary tools (angle grinder, welding machine), it will not cause any difficulties in manufacturing. The design of the overpass is collapsible, which allows it to be assembled for partial entry of a car:

For a full vehicle check-in:

And when disassembled, the overpass fits easily into the garage, on the side, without interfering with the car. The overpass is made of metal, so its reliability is beyond doubt. The overpass is installed using 12 M14 bolts. The overpass can be installed on almost any surface (flat and uneven).

By the way, despite the simplicity of the design, the manufacture of a mobile overpass will require about a week of working time.
By the way, during this time you can complete most of the car’s sound insulation.

Make a flyover with your own hands

Photo source:

The overpass is an indispensable tool for inspection and repair 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. For this purpose, it is often installed in the garage homemade overpass- a design with which you can examine the bottom of a 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 brickwork may collapse, which may require 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 an overpass made of railway sleepers is justified in a summer cottage 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 boards. 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 wooden structure One can note low durability, poor resistance to rotting 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 bases of the cabinets are assembled. The blanks are cut based on the size of the car wheels. The blanks can be laid out on a sheet of chipboard or other flat surface and fixed at an angle of 90 degrees (you can use a regular construction angle to determine the angle). After all measurements, the workpieces are welded together.
All parts are connected at right angles
The racks are being assembled. The height is about half a meter, the angle is about 120 degrees. Fixed, scalded.
Corners and side walls should be equal
The upper supports of the pedestals are welded. To do this, the upper corners are connected to the racks, set at an angle of 90 degrees, and scalded.
The finished supports are connected to the base, set at right angles and welded.
After assembly, you can additionally weld the main components
The dead end of the cabinet is welded. This is necessary to prevent the car from driving further and overturning. The part is made from a corner 63*63*5 mm.
Reinforcing bars are welded to the finished cabinet. To adjust the distance between them, you can use the same corner 63*63*5 mm. The reinforcement sections are laid so that their “herringbones” intersect.
A regular construction corner with a side of 63 millimeters is used as a template.
Assembly of gangways (bridges). The blanks are cut and fixed with clamps at the corners. Sections of reinforcement are welded to the corners, the distance can be determined using a template corner, the “herringbones” intersect. The corners are welded to the workpieces.
The car will drive onto the overpass using these bridges
The final stage is fitting. On level ground, both parts of the overpass are placed close to each other. The centers of the bollards are marked, the structure is adjusted to the width of the car. Holes are drilled in the ladders and cabinets, after which the elements are connected to each other using bolts. Thanks to the bolted connection, the overpass can be easily disassembled and reassembled later.

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 is 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.

Almost every motorist needs an inspection hole. With its help, you can perform a routine inspection of the car and its partial repair. Such a structure is especially important if there are no service stations nearby.

Why is the structure needed?

As already mentioned, if you have a car, then there may be certain problems with the mechanisms. Not all breakdowns can be fixed right in the garage. Sometimes you have to climb under the car. Naturally, doing repairs lying down is not very convenient. This is precisely why the overpass was invented.

It is not difficult to make such a structure with your own hands. You just need to decide on the design and assemble everything necessary materials. It should be noted that to build the structure you can use everything that is on your farm. For example, an overpass for car repairs can be made of metal stairs (above-ground version), bricks, or simply dug in the form of a hole (underground version).

What tools might you need?

It is quite simple to construct such a structure. You must first draw a diagram on paper, calculate its dimensions, and also select the necessary tool:

Welding (if a metal version is built).
Grinder (for cutting materials).
Shovel (if you want to make a hole or fix overhead posts).
Brick and sleepers.
Cement (to prevent the product from “driving”, it should be fixed concrete mortar).

From this list you choose what you will need depending on the materials.

How to make the simplest design option?

It is a structure on which a car can drive only with its rear wheels or only with its front wheels. This type of overpass for a car consists of identical structures that can be made of metal or wood. Please note that the width of such products should not be less than 40 cm. Otherwise, they may be unstable or too narrow.

This structure can be welded from corners. In this case, the cross-section of the elements is about 2.5 cm. To prevent the car from sliding off the overpass, limiters must be fixed on the racks. Their height is at least 7 cm. After all welding work is completed, sharp corners need to be removed using a grinder. In order for the product to last as long as possible, it must be coated with a special anti-corrosion compound or painted. Please note that one element of such a structure will have quite a lot of weight.

How to make a structure from stairs?

A similar overpass can also be done quite quickly with your own hands. It is a more advanced option than the previous one. To work you will need two metal stairs length of at least 3 meters, welding machine and angles.

First you need to treat all components with an anti-corrosion compound. Next, you need to weld 4 vertical supports to the edges of the stairs, on which they will stand (like benches). Their length should be sufficient so that it can be partially dug into the ground. Naturally, in this case it is better to choose corners or pipes. In any case, these elements must be strong enough to support the weight of the car.

After the main structure is assembled, it is necessary to fix it in the garage. Place the future overpass so that it is convenient for you to drive onto it. The posts in the ground must be fixed with concrete mortar. In order for the car to drive onto the structure, 4 more corners (on both sides) need to be welded to the stairs at an angle. It is better to unite them together with crossbars.

Features of the inspection pit arrangement

The construction of an overpass of this type is the most common. However, it is possible under one condition: you have a lot of free space. Such an inspection hole must have a depth of at least 1 meter. This parameter depends on the height of the person who will be repairing or inspecting the car. To prevent the earth from crumbling inside, it is better to cover the walls of the structure with boards. In order to get down into the hole comfortably, you need to either dig steps or install a ladder. Please note that the steps should be equipped with anti-slip pads.

Please note that the edges of such an overpass should be slightly above ground level. The length of the pit must correspond to the size of the machine. In this case, after driving in, the car should not block the descent stairs. As for the width of the ditch, it is about 1 meter. Safety flanges must be added to this distance.

As you can see, a do-it-yourself overpass can be built quite quickly. You just need to draw a diagram in advance and select materials.

Arrangement of the overpass

Naturally, the workplace must be arranged accordingly. For example, there should be a workbench nearby with all necessary tools. Everything you need for repairs should be within arm's reach.

You will also need to organize good lighting. It is better to use LED or fluorescent lamps. Inside the inspection pit, you can make additional shelves on which tools will be placed. Please note that they must be secured as well as possible, and at a level so that if any products fall, they cannot harm you.

The inside of the pit can be lined with bricks. It's better to build a foundation. The surface on which the car will stand must also be secured as much as possible. It is better to install it on pipes dug deep into the ground.

If you need a trestle, you can make it yourself in just one day.
