Elevator Wire Rope

Elevator rope as the name suggests, is used in the elevator of the steel wire rope, with the largest small manned elevator in the residential area, the elevator wire rope specifications generally use 8*19S+FC-8mm, 8*19S+FC-10mm.
In general, most of the new steel wire rope in production has been lubricated, but in the use of the process, the loss of lubricating oils and fats will be reduced. In view of the lubrication can not only for wire rope in transportation and storage period to the corrosion protection effect, but also can reduce the use of wire rope between the wire and between the strands and the wire rope and sheave grooves between wear and extend the service life of wire rope is also very useful. Therefore, in order to reduce the damage to the corrosion, wear and tear on the wire rope to the minimum degree, the lubrication inspection is very necessary. Must first choose the appropriate wire rope grease, elevator wire rope grease should be with a coefficient of friction of special friction oil, high performance wire rope grease is to maintain and extend the service life of the rope is the fundamental guarantee of wire rope. Wire rope at work and internal rendering 3D fretting friction, which requires lubricating grease for wire rope must have strong permeability to oil and grease lubrication oil molecular anti-wear agent ingredients can penetrate into the top of each wire. In addition, the wire rope grease must also have a strong adhesion performance. To ensure that their uniform adhesion to each wire rope. Usually the lubrication and maintenance of wire rope has several method a is will remove rope down and put them into the temperature in 80 ~ 100 degrees of lubricating oil soak about 2 ~ 4 hours. Another is lubricant brush directly on the steel wire rope, the key is brushing method and interval to master, generally about 12mm in diameter of wire rope, every 40 meters about brushing 1 kg of lubricating grease, brushing interval in two weeks or so; another is using special steel wire rope lubrication equipment lubrication of the steel wire rope with a brush to, this method is the most easy, but equipment cost is higher. What kind of lubricant and lubrication methods should be used in accordance with the requirements of the steel wire rope manufacturing plant. At present elevator maintenance unit really pay attention to the maintenance of steel wire rope is not many, many units have been used to replace the new wire rope, and do not pay attention to lubrication management. This is only one aspect of the safety requirements of the wire rope. In addition, it is also necessary to use of wire rope in the external conditions of such as: traction sheave groove surface wear, a wheel groove geometry are examined, to ensure the rope in the running process of make it always in good contact state to reduce the friction force to ensure the safe operation of the elevator.
