Problems solved by technology

Such a solution is peculiar and the ropes thus obtained are lighter than steel wire ropes, but, at least in the case of elevators designed for the most common lifting heights, man-made fiber ropes do not constitute any substantial advantage, especially since they Significantly expensive compared to steel wire rope

Embodiment Construction

[0064] Figure 1 is a schematic diagram of an elevator structure. The elevator is preferably a machine-room-less elevator, wherein the drive machine 6 is accommodated in the elevator shaft. The elevator shown is a traction sheave elevator with the machine above. The passing of each hoisting rope 3 of the elevator is as follows: one end of each rope is fixed fixedly to the anchor point 13, which is located at the top of the shaft, above the path of the counterweight 2 moving along the counterweight guide rail 11. From the anchor point each rope runs downwards and around a diverting pulley 9 which is suspended from the counterweight, which is rotatably mounted on the counterweight 2 and from which each rope 3 runs further upwards to the traction rope of the driving machine 6 Wheel 7 walks around the traction sheave along each rope groove of the sheave. From the traction sheave 7, the ropes further extend downwards to the elevator car 1 moving along the guide rails 10 of the ele...

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 there is diverting pulleys 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.

Description

technical field [0001] The present invention relates to an elevator. Background technique [0002] One of the purposes of elevator development work is to obtain effective and economical use of building space. In recent years, this compulsion to work has, among other things, resulted in a variety of elevator solutions without machine rooms. Some good examples of elevators without a machine room are disclosed in technical specifications EP0631967(A1) and EP0631968. The elevators described in these technical specifications are quite efficient in terms of space utilization, since they make it possible to dispense with the space required for the elevator machine room in the building without enlarging the elevator shaft. In the various elevators disclosed in these technical specifications, the machine is compact in at least one direction, but in other directions it may have much larger dimensions than usual elevator machines. [0003] In these basically good elevator solutions,...
