On the left and right sides of the center of the beam body (see figure), there are 3 mounting holes for the auxiliary suspension. According to the needs, the auxiliary suspension can be in different positions to lift different specifications of the car body, reflecting a good versatility. Each end is also equipped with a set of hanging ears for the overall lifting of the car body.

According to the tonnage of the car body, different types of lifting belts and special lifting hooks are configured under the beam to lift different car bodies.
