Abstract:
In an elevator, preferably one without machine room, a hoisting machine engages a set of hoisting ropes via a traction sheave, said set of hoisting ropes comprising hoisting ropes of substantially circular cross-section. The ropes have a load-bearing part twisted from steel wires of circular and/or non-circular cross-section. The steel wires of the hoisting ropes have a cross-sectional area larger than about 0.015 mm and smaller than about 0.2 mm and a strength exceeding about 2000 N/mm . The elevator preferably has a hoisting machine of substantially light weight relative to the nominal load.

Abstract:
In an elevator, preferably one without machine room, a hoisting machine engages a set of hoisting ropes via a traction sheave, said set of hoisting ropes having a load-bearing part twisted from steel wires of circular and/or non-circular cross-section, and in which elevator the hoisting ropes support a counterweight and an elevator car moving on their tracks. The weight of the hoisting machine of the elevator is at most about 1/5 of the weight of the nominal load of the elevator.
Abstract:
In an elevator, preferably one without machine room, a hoisting machine (6) engages a set of hoisting ropes (3) via a traction sheave, said set of hoisting ropes having a load-bearing part twisted from steel wires of circular and/or non-circular crosssection, and in which elevator there is diverting pulleys (9, 4) of which some is made larger than traction sheave. The weight of the hoisting machine of the elevator is at most about 1/5 of the weight of the nominal load of the elevator.

Abstract:
Elevator rope arrangement in which the elevator car (1) and counterweight (2), travelling along guide rails in an elevator shaft, are supported by suspension ropes (3), which are attached to the top part of the elevator car (1) and passed via at least one diverting pulley (4) to the counterweight (2). Separate hoisting ropes (5) are attached to the lower part of the elevator car (1) and passed to lower part of the counterweight (2) via at least one diverting pulley (8). The hoisting rope (5) is a substantially thin rope made of synthetic fibre and having a sheath of plastic material.
