The necessity of elevator maintenance services

&The necessity of elevator maintenance services: Elevator failures usually occur on the elevator hall door and car door, so attention should be paid to the maintenance of the hall door and car door. First, add oil to the refueling place on the upper sill of the door to keep it well lubricated, so that the elevator will not make unpleasant sounds during operation and when the door is opened.
During regular inspections of elevators, inspectors often find that a layer of oil has accumulated on the surface of the traction wire rope. This is caused by the lubricating oil seeping out of the wire rope mixed with dust. If it is not cleaned in time, it will not only affect the quality of the wire rope The service life will also change the friction coefficient of the traction rope in the traction sheave groove, reducing the traction capacity. When the car is lightly or heavily loaded, it may cause the traction rope to slip and cause the car to rush to the top or squat to the bottom.
