Among port machinery, fixed cranes are more common, which can help us complete the lifting and loading and unloading of materials. However, there is a prominent problem in the equipment, that is, the friction problem of the spreader. In order to extend the service life of the device and ensure the safety of the operation, we must find a way to reduce its friction. Since the rolling friction coefficient is significantly smaller than the sliding friction coefficient, that is to say, the reason why rolling is more labor-saving is because the friction is relatively small. Therefore, when lifting heavy materials, you might as well try this method, which is also beneficial to fixed cranes. Secondly, if the lubricity of the contact surface of the object can be increased, the required tension can be reduced, so the best way is to apply lubricating oil. The crane wire rope generally fixes a section of the rope head first, then winds the drum, then passes around the movable pulley, fixed pulley, movable pulley, and finally fixes the other end of the wire rope. The commonly used wire rope varieties for cranes are manganese phosphating coated wire rope and galvanized wire rope.
