| 摘要 |
The invention relates to an elevator provided with a coated hoisting rope (9), in which elevator a hoisting machine engages a set of hoisting ropes by means of a traction sheave (5), said set of hoisting ropes comprising coated hoisting ropes (9) of substantially circular cross-section which have a load-bearing part twisted from strong steel wires (16). The cross-sectional area of the steel wires (16) of each hoisting rope is larger than about 0.015 mm<2 >and smaller than about 0.2 mm<2>, and the strength of the steel wires (16) is greater than about 2000 N/mm<2>. Moreover, the core of each hoisting rope (9) consisting of steel wires (16) is coated with a substantially thin sheath (17) softer than the core, forming the surface of the hoisting rope. |
