The choice of the elevator rope

By the strand wire rope, steel wire and wire strand core composition. Elevator rope strand around the rope is a single spiral twisting from the core. Usually 50 to 65, or 60Si2Mn quality carbon steel wire. For security, elevator wire rope with a special number or 1 wire, the wire diameter limited to between 0.3 ~ 1.3mm. Traction elevator wire rope used with or West-style (X type) and W Ling swallow type (W type). Currently, the widespread use of the elevator made 8 or 6 or West-style wire rope shares, which 8X (19) used more often.

1. Examples rope mark recognition

1 000kg rated load of the passenger elevator, for example, the traction rope with 8X (19) -16-140 the right to pay, of which 8 is the number strand, X is or West-style, (19) for each strand in the wire root number, 16 is the nominal rope diameter (mm), 140 for the tensile strength of steel wire rope (kgf/mm2), the right to pay for the wire strands in the strand and cross the rope in the right direction of twisting. Traction rope made are the right cross.

2. Cord

Elevator wire rope are made of fiber with oil-soaked rope core, fixed rope strand core support and improvement of Shengsi position that contacts between the cushion the impact load, since the role of oil storage tank for long-term lubrication of wire rope oil source, so that well-oiled wire .

3. Or West-style (X-type) structure and characteristics of wire rope

Xilu elevator rope cross-section shares was 199 per share, plus the core plus the first layer second layer composed of a total of 19 wire: center wire 1, Ñ„1.2mm, the inner wire 9, Ñ„0.6mm the outer wire 9 Ñ„1.05mm. Outer wire diameter wire than the inner diameter large, so called rough-type wire rope outside. â‘  characterized the number of share the same inner and outer layers of steel wire, but the diameter range, the outer notch embedded in the inner layer, the layers from the same twisted wire, compact solid, easy to open-book. Increase in crude steel outer wear, inner steel wire increased flexibility will help each other when sliding bending, thus increasing the flexibility and service life of wire rope. â‘¡ wire parallel to the line of contact between layers, and good resistance to fatigue steel wire rope, steel wire inside the wear resistance between the good, the contact area increases, the contact stress decreases.
