What are the commonly used wire ropes for hoisting equipment? [answered]

The types of commonly used steel wire ropes for hoisting equipment are as follows:

1. Phosphating coated steel wire rope (Chinese patent). When the steel wire is phosphated by manganese series or zinc manganese series, the wear resistance and corrosion resistance of the steel wire surface rise comprehensively. It is not easy to wear and rust, which greatly improves the fatigue life of the steel wire rope. The fatigue life is three times that of the smooth steel wire rope with the same structure. The fatigue life can be verified through the fatigue test (it is credible to do the fatigue test in person). It is an upgraded product of the smooth steel wire rope, It can also replace the galvanized steel wire rope with thin zinc layer after plating (which can be tested by salt spray test or compared with corrosion resistance). It has long service life, lower unit use cost and better stability.

2. Galvanized steel wire rope includes hot-dip galvanizing and electro galvanizing. Generally speaking, the hot-dip galvanizing zinc layer is thick and the electro galvanizing zinc layer is thin

3. Stainless steel wire rope, mainly 304 or 316 stainless steel, has a very good anti-corrosion effect, but the price is expensive

4. Plastic coated steel wire rope. On the basis of carbon steel wire rope, the outer layer is coated with polyethylene, polypropylene or nylon

5. Smooth steel wire rope, with short service life and sharp reduction in market demand, will be completely eliminated by phosphating coated steel wire rope.

6. Steel wire rope for offshore engineering mooring

7. Cable and wire rope

For hoisting machinery used in atmospheric environment, manganese phosphating coated steel wire rope is preferred, hot-dip galvanized phosphating double coated steel wire rope is preferred in heavy corrosion environment, and marine steel wire rope is preferred in seawater. When purchasing, please note that the purchase invoice must indicate the name of the steel wire rope, such as phosphating coated steel wire rope or 316 stainless steel wire rope, in order to protect their legitimate rights and interests. In addition, the patent product is generally marked with the patent number on the outer package of the steel wire rope, and the warranty shall have main technical indicators, such as the type and weight of phosphating film, for reference only.
