Buffer Stops consists of a main frame and two pairs of boosters. The total length is 2800mm.

The elastic pressurizing device is composed of leaf spring, spring seat, wedge iron and bearing seat. It is installed in the brake rail of the main body frame and the brake rail of the booster. Its role is to form a pre-stress when the Buffer Stops is static, increasing Frictional resistance during braking, and when dynamic, the braking force can continue to function until parking.

The impact force of the cushion rubber sheet vehicle is transmitted from the buffer rubber sheet and the right and left support arms to the brake rail. Brake rails, spring seats. Frictional resistance with the base rail prevents the vehicle from sliding.
