8x19W Steel Wire Rope for Elevator traction High Speed and Safety

Product Description

Specification and structural uses of elevator wire rope (traction rope, speed limiter wire rope)

Installation and replacement of specifications for 8 x 19W+NF elevator wire rope

1, the elevator wire rope should be placed on the bracket in the installation and the fixed length cutting, and the clockwise rope is carried out in accordance with the rolling direction identified on the side of the round circle to avoid the internal stress produced by the steel rope.
2, installation and construction should avoid wear, scraping and dirt on the surface of the elevator wire rope, otherwise it will damage the traction wheel and wire rope.
8 x 19W+NF elevator wire rope specification model
3, the common model of the elevator wire rope is mainly 8 x 19W+NF-8.0MM/10MM/11MM/12MM/13MM/16MM, which is called the sisal core elevator steel rope with better toughness. It is to shorten the free draping time as far as possible when installing the wire rope. Otherwise, the wire rope will produce free rotation and even destroy the wire rope because of its own gravity. The twisting parameters cause the local relaxation of the wire rope. When the wire rope is working, the rope core is replaced by the steel wire force, which causes the core to be damaged first, and then the service life of the wire rope of the elevator is seriously reduced.
4, when installing the wire rope 8*19W+NF, the internal stress of the wire rope should be fully eliminated, that is, the full "release", and then the ends of the wire rope should be fixed. In order to avoid the rotation or deformation of the local force in the operation of the wire rope, the operation of the elevator is not stable, and the service life of the traction wheel and the wire rope is shortened.
5. After installing the wire rope, the tension of the wire rope must be carefully adjusted. The tension of the wire rope should be checked at any time and adjusted in time.
6. The wire rope is a very important safety part in the elevator. The elevator company designed and made the elevator according to its specifications. The wire rope with different technical requirements must be used in the replacement. When changing the traction wheel, it is necessary to select products that conform to the original design requirements, so as to avoid unnecessary losses.
7. When the elevator steel rope is replaced by the old ladder, the traction wheel should be replaced at the same time, or the traction wheel grooves are processed. Otherwise, the friction between the traction wheel and the wire rope will be caused by the difference between the original wheel groove of the traction wheel and the wire rope. When replacing wire rope, every elevator wire rope must be replaced at the same time.​
