coil transfer cars for tunnel construction

In the type 2 coil spring suspension, the coil spring also supports the weight of the vehicle. And the movement of the coil spring is controlled by the shock absorber. Notice that in both Type 1 and Type 2 designs, the weight of the vehicle is transmitted through the spring to the control arm at its bottom, and then through the control to the ball joint.
