The following are the key steps and considerations for choosing a lift support vehicle:

1. Before operation, be sure to turn on the power supply and verify that the motor power supply is correctly installed. At the same time, it is necessary to carefully check whether there is leakage or oil leakage of the lift machine to ensure the safety of operation.

2. Stop the car in the central position of the lift, so that the bracket arm of the lift can accurately support the predetermined support point of the vehicle chassis. Make sure the vehicle is in P or N gear and that the parking brake is activated. Adjust the vehicle so that the four support points (located at specific locations on the car's chassis, which usually have reinforced steel plates for increased load-bearing capacity) are aligned with the lift.

3. The process of lifting the vehicle shall be carried out in three stages. First, start the lift and pause when the support point approaches the bottom of the vehicle. At this point, you need to check the alignment of the support point with the vehicle. Then, start the lift again, and when the support point is in contact with the vehicle, the accuracy of the support point should be confirmed again. After confirmation, lift the vehicle to a height of about 300mm from the ground. Finally, push the vehicle from the side of the vehicle to test its stability, and after confirming stability, the vehicle can be lifted to the required working height.

4. Remove the fall safety device before lowering the vehicle.

In addition, regarding the car bumper, it is an important safety device used to absorb and reduce the external impact force, thereby protecting the front and rear parts of the body. Bumper manufacturing involves injection molding machine, bumper mold and spray painting equipment. It is worth mentioning that many years ago the front and rear bumpers of cars were channel steel made of stamped steel plates.

Various tools and devices, such as Phillips screwdrivers and sleeves, may be used during maintenance and repair. For example, when replacing the front bumper, it is usually necessary to remove the screws and nuts, which requires the corresponding tools to complete.

In general, whether it is the operation of the lift or the maintenance of the car bumper, it requires expertise and the appropriate tools to ensure the safety and efficiency of the job.
