Yes, the girder, also called the frame, is the foundation of the car. Generally, it consists of two longitudinal beams and several transverse beams. It is supported on wheels through suspension device, front axle and rear axle. It has enough strength and rigidity to bear the load of the car and the impact of the wheels.

It usually takes about 5 days to repair the deformation of the front cross beam head of an automobile. These methods are as follows:

1. It is necessary to prepare the equipment needed to correct the girder. Some beam shapers and fixtures, a small hammer, a middle hammer and some tools drive the damaged vehicle to the beam shaper;

2. Fix the four tires of the vehicle with clips to prevent the vehicle from dragging in the process of tensioning the main beam, rotate the straightening arm to the position of the main beam, and fix the next one with clips to prevent the tensioning arm from shaking during tensioning, thus fixing the straightening arm and the main beam together;

3. For the slight, it only needs to be stretched in the opposite direction of deformation. While stretching, you need to find a measuring point on the car body and measure the diagonal lines with a box ruler until the two diagonal lines are equal in length.

4. For the main girder with serious deformation, it is necessary to fix the tensioning position with a suitable fixture. Straighten the deformed girder first, and then pull it in the opposite direction of girder deformation. For severely deformed beams, pull them several times, not once.
