In electric hoists, the wire rope is a key component, and its condition directly affects the safety, performance, and lifespan of the electric hoist. The following is a detailed analysis of the various states of steel wire ropes in electric hoists:

1、 Normal state

Under normal use and regular maintenance, the steel wire rope of the electric hoist should be kept in good condition, specifically manifested as:

Neat appearance: The surface of the steel wire rope has no obvious wear, corrosion, rust or oil stains.

Complete structure: The strands and wires of the steel wire rope are arranged neatly, without looseness, breakage, or deformation.

Good lubrication: The surface of the steel wire rope should be coated with an appropriate amount of lubricating oil to reduce friction and wear.

Normal bearing capacity: The bearing capacity of the steel wire rope meets the design requirements and can meet the lifting needs of the electric hoist.

2、 Wear state

As the usage time increases, the steel wire rope will gradually wear out, specifically manifested as:

Diameter reduction: Due to friction and wear, the diameter of the steel wire rope will gradually decrease, affecting its load-bearing capacity.

Surface wear: There are obvious wear marks on the surface of the steel wire rope, such as scratches, pits, etc.

Loose strands: Some strands may become loose due to wear and tear, causing the overall structure of the steel wire rope to become unstable.

3、 Corrosion state

Electric hoists working in humid and corrosive environments are prone to corrosion of their steel wire ropes, specifically manifested as:

Surface corrosion: Rust spots or layers appear on the surface of the steel wire rope, reducing its strength and wear resistance.

Strand breakage: Severe corrosion may cause strand breakage, affecting the overall strength and safety of the steel wire rope.

4、 Fracture state

When the steel wire rope is severely worn, corroded, or overloaded, it may break, specifically manifested as:

Sudden breakage: During the lifting process, the steel wire rope may suddenly break, causing heavy objects to fall and resulting in serious safety accidents.

Wire breakage phenomenon: Before breakage, the steel wire rope may experience local wire breakage, which is a precursor to breakage.

5、 Maintenance and upkeep

In order to maintain the good condition of the electric hoist wire rope and extend its service life, regular maintenance and upkeep are required, including:

Regular inspection: Regularly inspect the surface condition, diameter changes, wear level, and corrosion of the steel wire rope.

Timely replacement: When severe wear, corrosion or breakage of the steel wire rope is found, a new steel wire rope should be replaced in a timely manner.

Correct lubrication: Apply an appropriate amount of lubricating oil to reduce friction and wear, and pay attention to selecting lubricating oil that matches the material of the steel wire rope.

Avoid overload: Strictly carry out lifting operations according to the rated bearing capacity of the electric hoist to avoid damage to the steel wire rope caused by overload use.
