Correction method of automobile girder;
1, equipment preparation. First of all, you need to prepare the equipment used to correct the girder. Girder, several fixtures, a small hammer, a medium hammer and several tools, then check whether the girder is clean and free of sundries, and then drive the damaged vehicle to the girder.
2. Fixation of the vehicle. Fix the four tires of the vehicle with clamps to prevent the vehicle from being dragged in the process of stretching the main beam, rotate the straightening stretching arm to the position of the main beam, and then fix the next one with clamp pins to prevent the stretching arm from shaking in the stretching process, so as to fix the straightening stretching arm with the main beam.
3. Determine the deformation degree of the main girder. For slight stretching, it is only necessary to stretch in the opposite direction of deformation. While stretching, find a measuring point on the car body, measure the diagonal lines with a box ruler, and stop stretching when the two diagonal lines are the same length.
