• Part 2 of 2: Using Overpasses
• Warnings

1 Check the rated maximum load capacity. This is the most important parameter for the strength of a flyover. The higher this value, the more secure you will be. The rated carrying capacity characterizes the maximum possible gross vehicle mass (GVW) that this overpass can withstand. This weight can be found on a sticker in the driver's door opening or in the vehicle manual. The loading capacity of the overpass should be significantly higher than the RMS of your vehicle in order to eliminate possible errors and to support the weight of the heavy front of the vehicle.

• This usually implies that two overpasses are used simultaneously. For example, a pair of 2.7 tonne flyovers securely hold the front of a 2,700 kg vehicle while using both overpasses at the same time.

2 Take into account the country of origin of this device. Overpasses made in the United States and the European Union are generally subject to stricter quality controls than devices from other countries. While there are also safe and well-made third-party flyovers available, care must be taken to get other people's opinions about such products before deciding to buy them.

3 Read reviews. Some car owners tell scary stories about how overpasses collapse under significantly less than nominal load. The risk of this is small, but it can be fatal, so it's worth looking online for reviews from other users.

4 Decide on the possibility of purchasing low ramps. Such overpasses have a gentler slope, so even a sports car can be driven onto them without scratching the elements of its chassis. As a rule, such devices are quite expensive, so they should only be purchased if a regular ramp cannot be used.

5 Check for rubber stops that prevent slipping on the floor. The underside of many ramps has anti-slip rubber elements that prevent the device from sliding back when the vehicle starts to run over them. This is especially important if the service is planned to be carried out on a smooth surface, because as the car hits the ramps, they will not drive forward.

6 Look for signs of damage. Throw away ramps if you find clear signs of corrosion, cracks or other defects on their surface.

7 Buy anti-rollbacks if necessary. A minimum of two wheel chocks are recommended whenever you drive your vehicle onto overpasses.During the operation of anti-rollbacks, problems very rarely arise, but if there is a smooth or slippery floor in the garage, it is better to purchase soft rubber stops.

Part 2 of 2: Using Overpasses

1. 1 Move the ramps directly under the front wheels of the vehicle. Install the tool with the narrow end right in the center of the tire. Check with a glance that the device is located as parallel to the car body as possible. Carry out a similar procedure with the second overpass on the opposite side of the vehicle.
   • If the wheels are turned to the side, align them and try again.
   • Always work on a sturdy, horizontal platform or solid surface. Do not carry out repairs on wet or slippery surfaces, as this may cause problems when the vehicle is lifted up the overpass.
2. 2 Climb exactly the center of the ramp. Get in the car and go up the flyover. Get out of the car and make sure the front tires are flat on the front. If not, roll back and try again.
   • Most overpasses have a small ledge at the end, which will allow the driver to feel that he has already arrived at the edge. If this protrusion is too small, then you will need an assistant who must guide you and prevent the car from falling off the overpass.
   • Drive slightly faster if overpasses slide forward as the vehicle moves, but do so gently and carefully. If it is not possible to climb up the ramps in this way, it is necessary to fix them in place by placing the board in the gap between the garage wall and the rear side of the overpass.
3. 3 Apply the parking brake. Use the handbrake to prevent the vehicle from rolling down the ramp accidentally as soon as you make sure its wheels are centered. Stand on the side and gently rock the machine to make sure it is stable.
4. 4 Support the rear wheel with two chocks. Place one shoe at the front of the rear wheel and the other at the back. This is an additional safety measure that will prevent the vehicle from rolling in any direction. Safe access to the underside of the vehicle is now ensured.
   • If you want extra safety, you can jack the car.

Warnings

• While under the bottom of the car, do not carry out manipulations that can lead to unlocking the parking brake or transmission mechanism.
• Do not try to make your own flyover. At first glance, this is very simple, but commercial fixtures are much stronger than those that can be made in artisanal conditions.
