Lubrication and anti-rust of elevator wire ropes

Lubrication and anti-rust of elevator wire ropes

In recent years, small machine rooms and machine room-less elevators have been widely used, which has significant effects in saving civil construction costs and reducing energy consumption. However, at the same time, the use of low-power permanent magnet synchronous traction machines has led to a reduction in the diameter of the traction sheave. The small rope diameter reduces the corrosion resistance of the steel wire rope to a certain extent, making the steel wire rope more susceptible to corrosion. Severe corrosion will reduce the cross-sectional area and mechanical properties of the steel wire rope, causing the fatigue life of the steel wire rope to be shortened; corrosion pits on the surface of the steel wire will form fatigue sources, causing broken wires and strands of the steel wire rope, causing brittle fractures of the steel wire rope and other safety issues. ACCIDENT.
