What factors should be considered when selecting hoisting wire rope for mine transportation and hoisting equipment?

1 phosphating coated steel wire rope (patented product), the steel wire is phosphatized by manganese series or zinc-manganese series, and the surface of the steel wire is very wear-resistant, effectively inhibiting the occurrence of fretting wear. It is an upgraded product of smooth steel wire rope, and its service life is far longer than that of smooth steel wire rope with the same structure, including steel wire rope imported from Germany, Japan and other developed countries (phosphating rope is about 3 times of smooth steel wire rope at present, and it may be improved in the future, and the phosphating film is 3-60g/m2. After phosphating, this innovative technology is suitable for almost all kinds of carbon steel wire rope, such as elevator wire rope and important wire rope.

2. Galvanized steel wire rope, including hot dip galvanizing and electro-galvanizing. The thicker the zinc layer, the longer the service time and the thinner the zinc electroplating. The thicker the zinc layer, the stronger the corrosion resistance. Because the phosphating film has certain corrosion resistance, manganese phosphating film steel wire rope can replace some varieties of thin galvanized steel wire rope, such as Grade B galvanized steel wire rope in GB89 18-2006.

3. Stainless steel wire rope, steel wire rope twisted with stainless steel wire, such as 304 or 3 16 stainless steel, is more expensive. Manganese phosphating film can also greatly prolong the service life of stainless steel wire (phosphating of stainless steel wire requires special phosphating formula).

4. Plastic coated steel wire rope: on the basis of carbon steel wire rope, the outer layer of steel wire rope or strand rope is coated with polyethylene or polypropylene.

5.1Smooth steel wire rope produced in England in 834, 1939 produced and used in Tianjin No.1 Steel Wire Rope Factory in China. With the phosphating coated wire rope entering the market, it will be completely replaced by phosphating coated wire rope.

The following factors should be considered when selecting wire rope: load weight (based on which the minimum breaking force of wire rope is calculated), the number of pulley blocks, whether the service environment is corrosive (galvanized wire rope is needed in corrosive environment) and whether it needs wear resistance (triangle wire rope or compression wire rope for mine), which is for reference only.
