[0002] Gantry cranes are mainly composed of metal structures, including a portal frame, a load-bearing main beam and two supporting bases installed under the load-bearing main beam. A pulley is fixed at the lower end of the base, and the pulley slides on a ground rail set on the ground. There is a transversely movable crane on the load-bearing main beam, and the cargo is transported at the port terminal by the crane.

[0003] However, traditional gantry cranes move on the ground rails by pulleys during the movement process. Since the goods are transported at the port terminal, the environment at the terminal is relatively humid. The humid air will combine with oil and foreign matter to form a layer of dirt on the ground rails. When the pulley moves on the ground rails, it will stick to more and more dirt, which will affect the smoothness of the base movement and the service life of the gantry crane base and pulley.
