Homemade overpasses for car repairs. Assembling a mini-overpass with your own hands: wooden and metal. Requirements for the overpass

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.

Types of garage overpass structures

For high-quality and comfortable repair and maintenance of your car, you need to properly organize workplace, especially to ensure its safety for humans. For this purpose, a variety of types 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 foundation, you need inner layer Cover the device with bricks or cover 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.

Advantages of the design compared to conventional inspection hole, are:

• Availability larger area for carrying out work.
• Lots of light.
• More comfortable.
• 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: Main Feature homemade overpass– the presence of a solid base, which allows you to minimize the likelihood of the car falling. To make it, you should only choose quality materials high strength.

The overpass in the garage can be located:

• In the corner.
• Near 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 a trestle it is possible to carry out the required volume 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 carry out repair work in 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 spending a lot of time on suitable for a dacha design option from brickwork on 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 are 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. From sizes cross section depends on how high the car is raised.

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.

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 run 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 necessary thing in the garage, now you don’t have to struggle and put the jack up every time, you just take it, drive it and you’re done. I think someone will like this idea and have a smooth road for everyone.

Simple do-it-yourself overpass – Crafts for cars

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 made from a corner 50 x 50 mm.

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 a support for the 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.

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:

• Pipe square cross-section 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 conduct Maintenance and repairs independently in various places depending on the 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, it is necessary to organize the overpass workplace for 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 household plots, country houses, 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 wooden steps 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 block 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 metalworking 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 some thick boards or some scrap metal, welding machine and Bulgarian. 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:

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

Mini overpass the first category is usually collapsible and requires small quantity 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 Carrying out car repairs 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 repair site takes place at best case scenario 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 is 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 find 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, about 5 m long, 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. Place 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. 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.

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 sound insulation of the car.

Make a flyover with your own hands

Photo source:

Almost every motorist needs an inspection hole. With its help, you can do a routine inspection of the car and its partial renovation. 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:

1. Welding (if a metal version is built).
2. Grinder (for cutting materials).
3. Shovel (if you want to make a hole or fix overhead posts).
4. Brick and sleepers.
5. 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 everything welding work will be completed, sharp corners must 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 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. To make it convenient to go down into the hole, 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 arrange 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.

“The presented material will show you how to independently make a mini-overpass for repairing your car in the garage. Car owners know very well that as they operate, they often have to repair the car and carry out an inspection; it is best to do this in a warm and well-lit garage with an inspection hole. But often modern garages they don’t have one, because there is a huge number of different car services and workshops. This is of course good, but you will have to pay for the services, and the cost of a car today is already affordable. So, in order to save money and repair the car yourself, you need to make a mini-overpass. The base will be a 50x50 mm corner, crossbars made of 12 mm reinforcement with a pitch of 75 mm.

This overpass is installed to the width of the vehicle track and is driven onto it by the front or rear wheels. Attention! When installing the car on an overpass, be sure to put the handbrake on and place a kickback or stop under the wheel.

What will you need to create a mini overpass for cars?

Materials

1. corner 50x50 mm
2. reinforcement 12 mm
3. dye

Tools

1. welding machine
2. grinder (angle grinder)
3. roulette
4. brush

Step-by-step instructions for making a mini-overpass.

And so, first of all, let's get acquainted with the detailed drawing that the author compiled. Next, according to the dimensions of the drawing, it was welded this design, for which a 50x50 mm corner and 12 mm reinforcement were used. The second part is made in exactly the same way.

The product is then painted bright yellow.

After the paint has dried you can test it 😉
This mini-overpass is very convenient to store in the garage.
It is so compact that you can even store it at home.

Transport periodically needs to have its chassis checked. For this it is convenient to use an overpass. Design used at service stations.

If the owner of the car does not want to spend money on the services of car mechanics, he can carry out the inspection on his own by lifting it using an overpass.

This method is worthy competition inspection hole for easy access to the bottom of the machine. Installing the overpass yourself will help save money.

Some types

Based on the type of device, there are two types of overpasses for road transport:

1. Full size.
2. Mini overpass.
3. Mobile - the design is discussed in detail in this article, this collapsible overpass having small dimensions. It can be easily located in the garage and, if necessary, can be quickly installed. Designed for inspection of passenger vehicles.

The device includes:

• four stands for supports;
• two pairs of track with a lock to prevent the car from rolling;
• two pairs of inclined ramps for entry;
• a sufficient number of stiffening beams to fasten the parts to each other.

They build a structure from steel.

Stages of preliminary work

Creation begins with a diagram and selection of the type of structure (stationary or portable) and the material from which the work will be performed.

General dimensions:

• height – up to one meter;
• width - about two meters;
• the length of the ride is one meter;
• the length of the horizontal platform is from a third of a meter.

The overpass is two symmetrical combined structures. From the side in the drawing it is a rectangular trapezoid. The tracks must be fixed between each other to resist displacement when a car drives onto it.

The steel structure is mounted using:

• Bulgarians;
• nuts, bolts.
• welding machine;

As a frame, reinforcement and a forty-millimeter corner are used. The assembled structure is painted on top.

Steel structure

The most common of the manual ones is a mini overpass made of metal.

This solution has some advantages:

• high mobility;
• ease of installation – does not require special skills;
• safety and durability.

Although a self-made overpass can last for decades, over time each structure wears out. If you maintain it properly and treat it against corrosion, its service life will increase significantly.

Welding of the overpass proceeds as follows:

• a corner is prepared and two rectangular trapezoids are mounted;
• combine them with each other using a corner;
• additional stiffening ribs are formed from the remains and trimmings of the corner from the sides;
• prepare the reinforcement and weld it to a horizontal base and onto an inclined plane;
• clean with a metal brush, open paint coating for metal.

The technique is repeated for the symmetrical part of a pair of tracks. On the main platform, you can make a limiter side so that it is impossible to cross the permitted mark.

It is convenient to store it in a vertical position.
