Background

If the cart of a single crane accidentally rushes to the track stroke end, the buffer can interact with the end stop of the track at the same horizontal height; if two cranes on the same span track collide with each other, the buffer acts on the opposite surfaces of the metal structures of the two cranes. The buffer is deformed by itself, and the collision kinetic energy is quickly converted into elastic potential energy to be absorbed, so that the impact effect of collision force is reduced, and the damage to the crane is avoided.
