The basic task of pulling for vehicle body correction is to restore the damaged vehicle body to its original shape, and in addition, to restore the metal to its original lattice state.

After the completion of the vehicle body calibration repair, the final inspection should be carried out in a timely manner. The inspection can be carried out in two situations: when the fixed device is not used for repair, the final measurement inspection should be carried out, and compared with the vehicle body and frame size manual to determine whether the vehicle body calibration requirements are met. When repairing on the fixed device, there is no need to measure, only to determine whether the vehicle body control points match the fixed device.
