    Wire rope is the key to lifting in explosion-proof electric hoist operation


Description: Explosion-proof electric hoist is suitable for small lifting equipment, and has the advantages of light weight, small size and convenient operation. The device to be protected by the explosion-proof wire rope electric hoist is a wire rope, and some problems often occur during the use of the wire rope. So what are the reasons for the damage of the wire rope? Introduce to you:

Explosion-proof electric hoist is suitable for small lifting equipment, and has the advantages of light weight, small size and convenient operation. The device to be protected by the explosion-proof wire rope electric hoist is a wire rope, and some problems often occur during the use of the wire rope. So what are the reasons for the damage of the wire rope? Introduce to you:

1. Fracture phenomenon of steel wire rope

The reasons for this situation are generally divided into three cases: ① During the use, there are some excessively violent impacts, which cause the rope to run overload, damage or wear, and cause fracture; ② some places of the rope have severe corrosion caused Fracture; ③ Under the three conditions of fatigue, speeding and slipping, the steel wire rope may cause one or even a few strands to break.

2.Twisting and bending of steel wire rope

This situation of the wire rope is generally caused by improper use methods, such as improper pulling of the wire rope from the sheave, or incorrect winding of the wire rope in the drum, resulting in improper wire rope distortion and distortion. Bending phenomenon.

3.Fatigue and fracture of wire rope

There are two kinds of situations that cause fatigue fracture of steel wire ropes: ①Because the steel wire rope is used too frequently, the running beam causes the steel wire rope to bend in the rope card, which causes the fatigue and fracture of the steel wire rope; ② During lifting operations In the middle of the year, the wire rope was damaged, mainly due to the improper use of the wire rope in lifting operations, which caused the wire rope to break.

4, the wire rope twist length is extended or reduced

This situation generally occurs because during the lifting operation, the steel wire rope is often overloaded, the core twist distance in the steel wire rope is deformed due to extrusion, and the twist distance of the steel wire rope is extended or reduced.

In general, there are many reasons for the problems of wire ropes, some of which are due to the natural loss of the wire rope for a long time, but there are also many cases due to improper man-made operation or the influence of external forces. Wire ropes are one of the important parts of explosion-proof electric hoists . First, the safety of steel wire ropes without loss is the basis for ensuring the normal operation of cranes, so people must use the correct method in the use of steel wire ropes.
