Elevator with hoisting and governor ropes

摘要

An elevator may include: a hoisting machine; hoisting ropes; a traction sheave that includes grooves; and diverting pulleys. Each of the hoisting ropes may individually contact one of the grooves. Each hoisting rope may include steel wires of circular, non-circular, or circular and non-circular cross-section, twisted together to form strands. The strands of each hoisting rope may be twisted together to form the hoisting rope. A thickness of each of the hoisting ropes may be greater than or equal to 2.5 mm and less than or equal to 8 mm. A cross-sectional area of the steel wires of the hoisting ropes may be greater than 0.015 mm2 and less than 0.2 mm2. The strength of the steel wires may be greater than 2,700 N/mm2 and less than 3,000 N/mm2.
