The selection of wire rope for wire rope electric hoists is particular, and it is not a matter of using any wire rope casually. Usually, wire rope electric hoists use phosphating coated wire ropes. So, what are the main advantages of using this type of wire rope?

Firstly, we need to clarify that the reel of the wire rope electric hoist is its storage location. During the operation of the wire rope electric hoist, the loss of the wire rope is not only caused by the load of the lifting operation, but also by the friction between the wire ropes during the winding process of the reel. Frequent friction can cause loss to the wire rope. Therefore, it is necessary to choose a high-strength wire rope that is relatively wear-resistant, and phosphating coated wire rope has become an ideal choice.

Phosphating coated steel wire rope, also known as manganese based phosphating wear-resistant coating steel wire rope, is a type of steel wire rope that has undergone phosphating treatment. The phosphating film makes the surface of the steel wire more wear-resistant and improves its anti-corrosion ability. The porous structure of the phosphating film can increase the storage capacity of lubricating grease on the surface of the rope making steel wire, reduce the friction coefficient, promote sliding, delay the occurrence of micro motion wear damage on the steel wire surface, suppress the initiation of fatigue microcracks, and greatly extend the service life of the steel wire rope.

This is the true purpose of using phosphated coated steel wire rope for electric hoists, and it is precisely this type of steel wire rope that allows electric hoists to have a longer service life.
