Lookout pit is needed by almost any motorist. With its help you can make a scheduled inspection of the car and its partial repair. Especially important is the construction in the event that there are no TO stations nearby.
Why do we need a design?
As already mentioned, if you have a machine, then there may be some problems with the mechanisms. Not all faults can be eliminated right in the garage. Sometimes you have to climb up and under the car. Naturally, doing repairs lying is not very convenient. It was for this purpose that the overpass was invented.
It is not difficult to make such a construction with your own hands. You just need to decide on the design and collect all the necessary materials. It should be noted that to build a structure you can apply everything that is in your household. For example, the overpass for machine repair can be made of metal stairs (aboveground version), bricks or simply excavated in the form of a pit (underground version).
What tools may be needed?
It is quite easy to construct such a structure. You must first draw a diagram on paper, calculate its dimensions, and also pick up the necessary tool:
- Welding (if a metal version is built).
- Bulgarian (for cutting materials).
- A shovel (if you want to make a pit or fix overhead racks).
- Brick and sleepers.
- Cement (so that the product does not "ride", it should be fixed with concrete solution).
From this list you choose what you will need depending on the materials.
How to make the simplest version of the design?
It is a structure on which the car can only leave the rear or only the front wheels. Such an overpass for a car consists of identical structures, which 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.
Weld this design can be from the corners. In this case, the cross-section of the elements is about 2.5 cm. In order for the car not to slip off the trestle, limiters must be fixed on the posts. Their height is at least 7 cm. After all the welding work is completed, the sharp corners must be removed with the help of a Bulgarian. 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 enough weight.
How to make a structure of stairs?
Such an overpass is also done quickly enough. It is a more perfect option than the previous one. For work you will need two metal stairs with a length of at least 3 meters, a welding machine and corners.
To begin with, all components must be treated with an anticorrosive compound. Next, to the edges of the stairs, you need to weld 4 vertical supports, 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's convenient for you to stop by it. Racks in the ground must be fixed with a concrete solution. In order to allow the car to enter the structure, it is necessary to weld 4 more corners (on both sides) to the stairs at an angle. Between them it is better to combine cross-members.
Features of the arrangement of the inspection pit
The construction of a flyover of this type is the most common. However, it is possible under one condition: you have a lot of free space. Such an inspection pit should have a depth of at least 1 meter. This parameter depends on the growth of the person who will be engaged in repair or inspection of the car. To the ground does not crumble inside, the walls of the structure is better to cover with boards. To go down into the pit was convenient, you either need to dig up the steps, or put a ladder. Note that the steps should be equipped with anti-slip overlays.
Note that the edges of such a flyover should be slightly above ground level. The length of the pit must match the size of the machine. In this case, after the arrival car should not overlap the ladder for descent. As for the width of the ditch, it is about 1 meter. To this distance, you need to add safety flanges.
As you can see, the overpass is built quickly enough. You just need to draw a diagram and select the materials in advance.
Naturally, the workplace should be appropriately equipped. For example, a workbench with all the necessary tools should be next to it. All that will need to be repaired must be at arm's length.
You 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 the tools will be placed. Please note that they should be fixed as well as possible, and at the level, so that in case of falling of any products, they could not harm you.
Inside the pit it is possible to impose a brick. It is better to equip the foundation. The surface on which the car will stand is also to be fixed as much as possible. It is better to install it on pipes buried in the ground to a greater depth.
If you need an overpass, you can do it yourself with one's own hands in just one day.
