Abstract
An elevator may include: a hoisting machine; hoisting ropes; a traction sheave that includes grooves; a counterweight; an elevator car; counterweight guide rails; and elevator car guide rails. 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 hoisting rope may be greater than or equal to 2.5 mm and less than or equal to 8 mm. Each hoisting rope individually may contact one of the grooves. A cross-sectional area of the steel wires may be greater than 0.015 mm2 and less than 0.2 mm2. The strength of the steel wires may be greater than 2300 N/mm2 and less than 2700 N/mm2.
