What are the preparations for checking the four-wheel alignment device

After driving for a while, the car may experience displacement, and there may also be abnormal damage to the tires, such as unilateral damage, uneven or feather shaped damage, heavy or light steering wheel, and continued shaking when driving fast. What is the preparation work for checking the four-wheel alignment device of a large vehicle?

1. Drive the car into the lift. Before driving in, use a locking pin to lock the angle brace to avoid rotation, and adjust the car to the elevator so that the front tire is located in the middle of the angle brace. When the car is stationary, apply the brake and place the tire wedge on the rear wheel to ensure that the car does not move.

2. Inspect the chassis components of the car, including rubber covers, bearings, shock absorbers, pull rod balls, etc., check the tire pressure and specifications, and check if the deep layers of the tread patterns are the same and if there are any gravel. If there are abnormal phenomena, effective measures should be taken to ensure the accuracy of the detection effect.

3. Open the computer and enter the main interface of the measurement software.

4. The purpose of installing monitoring. During installation, special attention should be paid to clamping the two small ones onto the front tire hub and the two large ones onto the rear wheel, ensuring that the fixtures point towards the camera.

5. After installing the 4 targets, click on the main interface "System Management - Target Monitoring" to enter the target monitoring interface. The ascending vehicle causes all four targets to occur within a reasonable area. Immediately press and hold the safety button for locking the elevator car after it is in place.
