Elevator
First Claim
1. An elevator without a machine room, comprising:
- a hoisting machine;
a set of hoisting ropes;
a traction sheave that comprises a plurality of grooves; and
diverting pulleys;
wherein the hoisting machine engages the set of hoisting ropes via the traction sheave,wherein each of the grooves has an opening for receiving an individual hoisting rope from among the hoisting ropes,wherein each respective hoisting rope of the hoisting ropes comprises steel wires of circular, non-circular, or circular and non-circular cross-section, twisted together to form strands,wherein the strands of each respective hoisting rope are twisted together to form the respective hoisting rope,wherein a thickness of each of the hoisting ropes is greater than or equal to about 2.5 mm and less than or equal to about 8 mm, andwherein an average of wire thicknesses of the steel wires of the hoisting ropes is greater than or equal to 0.1 mm and less than or equal to 0.4 mm, andwherein the strength of the steel wires of the hoisting ropes is greater than 2,300 N/mm2 and less than 3,000 N/mm2.

Abstract
An elevator may include: a hoisting machine; a set of hoisting ropes; a traction sheave that comprises a plurality of grooves; and diverting pulleys. The hoisting machine may engage the set of ropes via the traction sheave. Each groove may have an opening for receiving an individual rope. Each 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 rope may be twisted together to form the respective rope. A thickness of each rope may be greater than or equal to about 2.5 mm and less than or equal to about 8 mm. An average of wire thicknesses of the steel wires may be greater than or equal to 0.1 mm and less than or equal to 0.4 mm. The strength of the steel wires may be greater than 2,300 N/mm2 and less than 3,000 N/mm2.
