Inspection and adjustment methods for low flatbed semi-trailers

1. Park the vehicle on level ground without braking.
2. Take a point on the outer inner layer of the front axle wheel rim, one point on each side, with symmetrical positions.
3. Based on the core of the traction pin, accurately measure the distance to the above two points and specify "3mm of L1-L2i". If there is a deviation, adjust the movable pull rod of the rear axle until it reaches the specified error.
Before precise measurement, check the measurement standard value of the corresponding point on the rear wheel rim and specify the 2mm of the old 181-821. If there is any deviation, adjust the rear wheel tie rod so that the front and rear wheels are parallel to each other until the error meets the requirements.
5. Tighten the fastening screws on the front and rear movable pull rods.
After the adjustment is completed, stop in place without braking for about one kilometer and check the above specifications. If there is no change, the adjustment will be successful.
7. During the entire adjustment process, the pull rod should be in operation, that is, once the pull rod rotates, the elevator car bearings move, and the adjustment effect of the pull rod is normal.
