1. Since the galvanized steel wire rope is composed of multiple steel wires (for example, the 8*19S structure steel wire rope is composed of 152 steel wires), in the working state, the relative slippage of the steel wire caused by the bending of the steel wire rope will generate a large friction force. The special grease for wire rope can reduce the friction between the wire rope and the traction friction under the premise of ensuring the friction force between the wire rope and the traction, and effectively prolong the service life of the wire rope.
2. The galvanized steel wire ropes have been initially lubricated by a special spraying process, and all the steel wire surfaces are covered with a lubricating layer. If the surface of the steel wire ropes is cleaned after installation, the steel wire ropes must be post-lubricated in time.
3. The surface of the wire rope should be cleaned and maintained regularly (such as half a year or 100,000 times of operation, depending on the environment and frequency of use), and liquids such as cleaning agents should not be used to clean the wire rope during cleaning and maintenance, otherwise it will affect the rope. The oil content and oil content in the core will affect the normal use of the wire rope.
4. When cleaning and maintaining the wire rope, the surface of the wire rope should be cleaned with brush, cotton yarn, compressed air, etc. After the wire rope is cleaned, the surface of the wire rope should be oiled in time with the special grease for the wire rope.
5. Excessive lubrication will make the friction between the wire rope and the traction not guaranteed. The grease on the surface of the wire rope should be thin and uniform (according to the grease requirements of each company, the amount of coating varies).
Remember: steel wire ropes for elevators cannot be used without oil, and the unlubricated wire ropes will seriously affect the life of the wire ropes and traction.
Development direction of elevator wire rope technology: manganese wear-resistant phosphating coating elevator wire rope is an upgraded product of smooth elevator rope, which represents the development direction of high-performance galvanized wire rope manufacturing technology and has broad application prospects.
