What is the safety commitment of the elevator after replacing the wire rope?

Main varieties of wire rope, 1. Phosphating coated steel wire rope is an invention patent of China. After phosphating treatment, the wear resistance, corrosion resistance and rust resistance of steel wire rope are improved in an all-round way, and its service life is 2-3 times that of smooth steel wire rope (pay attention to the difference with the production process of smooth steel wire rope). 2. Galvanized steel wire rope, 3. Stainless steel wire rope, 4. Plastic coated steel wire rope and 5. Smooth wire rope will be completely eliminated by phosphating coated wire rope. Manganese phosphating coated steel wire rope is preferred for atmospheric environment, and hot dip galvanized steel wire rope is preferred for corrosive environment.

Elevator wire rope is an important variety, which involves personal safety. Therefore, the purchase of elevator wire rope needs to identify enterprise qualifications. Production enterprises need to have production licenses issued by national government departments and provide quality certificates. Some small wire rope factories have no qualifications but seize the maintenance market at low prices. In the event of an accident, the maintenance unit must bear legal responsibility.

The replacement of elevator wire rope must strictly follow the original design of the elevator, and the structure, diameter and strength grade of the wire rope must follow the meta-design. If you need to change it, you must consult the elevator manufacturer first and get a positive answer before implementing it.

The process of replacing wire rope needs to strictly follow the industry norms of elevator installation and debugging.
