    Under what circumstances does the explosion-proof electric hoist wire rope need to be replaced?


Description: Explosion-proof electric hoist is divided into explosion-proof electric chain hoist and explosion-proof wire rope electric hoist. In a certain sense, the chain of the explosion-proof electric chain hoist is more durable than the wire rope, because the wire rope of the wire rope electric hoist is wound by a strand of steel wire. It is completed, so if the wire rope may be worn, broken or knotted due to some reasons after a long period of use, under what circumstances do you need to replace the wire rope with a new one?

Explosion-proof electric hoist
The steel wire rope is one of the main components of the explosion-proof electric wire rope hoist. The quality of the wire rope directly determines the normal operation of the explosion-proof electric hoist. Therefore, in addition to the daily maintenance, it must be replaced in time to avoid affecting the normal operation of the explosion-proof electric hoist. To avoid safety accidents, then under what circumstances does the explosion-proof electric hoist wire rope need to be replaced?
Generally speaking, the wire ropes of explosion-proof wire rope electric hoists should be scrapped when the following conditions are met:
1. When the broken wire reaches more than 5 wires in one pitch, it should be scrapped.
2. During the use of explosion-proof electric hoist steel wire rope, if the whole strand of the wire rope breaks or the core of the wire rope is squeezed out, causing structural damage, the wire rope should also be scrapped.
3. Overloaded used steel wire ropes can no longer be used. When the appearance of the steel wire ropes is severely deformed, the rope core is extruded or there is obvious crimping, and the accumulation phenomenon should be discarded.
4. The explosion-proof electric hoist wire rope is worn and the diameter is reduced. If it exceeds 40% of the wire rope diameter, it needs to be replaced.
5. Wire ropes containing acid, flammable or toxic materials during transportation or hoisting of metal solutions are corroded by chemical media and should be scrapped.
