Next, China Elevator Lifts Factory introduces the main varieties of wire ropes used in elevators:


1. Phosphating coated steel wire rope, the steel wire is treated with manganese or zinc manganese phosphating, and the surface of the steel wire is very wear-resistant, which effectively inhibits the occurrence of fretting wear. It is an upgraded product of the smooth steel wire rope and has a long service life in the atmospheric environment. Far beyond the smooth wire rope with the same structure, including imported smooth wire rope.


2. Galvanized steel wire rope, including hot-dip galvanized and electro-galvanized, the zinc layer of the hot-dip galvanized steel wire is thicker, the thicker the zinc layer, the stronger the anti-corrosion ability, the longer the use time, the thinner the electro-galvanized. Hot-dip galvanized steel wire rope should be used in fresh water or sea water. Because the phosphating coating has certain anti-corrosion performance, the manganese phosphating coating steel rope can replace some types of thin zinc layer galvanized steel rope, such as high temperature environment with atmospheric environment but humid air.


3. Stainless steel wire rope, using stainless steel wire twisted steel wire rope, such as 304 or 316 stainless steel, the price is relatively expensive, the manganese phosphate coating treatment of the stainless steel wire can also greatly extend the service life.


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

Elevator traction wire rope, generally composed of 6-8 wires, safety factor is 12, safety performance is guaranteed, including safety calculation in engineering design and actual operation test have proved its safety, so it will be used in large-scale engineering . The failure process of the wire rope is fretting fatigue. The wire breaks first, the strand breaks occur, and finally the rope breaks. This takes a long time. The maintenance staff needs to check the condition of the wire rope every month. The number of broken wires must be replaced with new ones. Wire rope.
