The steel wire rope is one of the main load-bearing components of the electric hoist, and it plays a very important role. Steel wire rope is composed of steel wire, rope core, and lubricating grease. The core of steel wire rope can be divided into several categories according to the different materials.

1、 Organic core: made of hemp rope soaked in lubricating oil, which can provide lubrication during operation. Organic core steel wire rope has good flexibility but poor ability to withstand lateral pressure.

2、 Asbestos core: Made of asbestos rope, the performance of asbestos core steel wire rope is similar to that of steel wire rope with a core, but it can withstand high temperatures.

3、 Metal core, made of soft steel wire, can withstand high temperatures and large lateral pressures, but has poor lubrication. In recent years, spiral metal tubes stored with lubricating oil have also been used as rope cores.

The quality of the steel wire rope directly affects the safety of the use of the steel wire rope electric hoist, so it is necessary to choose high-quality steel wire rope in order to improve the safety of the operation of the steel wire rope electric hoist.
