AI Technical Summary

Problems solved by technology

Such a solution is unstable 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 offer any significant advantages, especially since they are used in conjunction with Very expensive compared to steel wire rope

Embodiment Construction

[0049] figure 1 It is a schematic diagram of the structure of an elevator. This elevator is preferably a machine-room-less elevator in which the drive machine 6 is placed in the elevator shaft. The elevator shown in the figure is a traction sheave elevator with the machine above. The running of the elevator hoisting rope 3 is as follows: one end of the rope is immovably fixed to an anchorage 13 arranged in the upper part of the shaft above the path of the counterweight 2 moving along the counterweight guide rails 11 . From this anchorage, the rope goes down and around the deflection pulleys 9 on which the counterweight is suspended, these deflection pulleys 9 are rotatably mounted on the counterweight 2, and the rope 3 then goes up to the traction sheave 7 of the driving machine 6 , bypass the traction sheave along each rope groove on the sheave. From the traction sheave 7, the rope 3 goes down to the elevator car 1 moving along the car guide rails 10, passes under the car ...

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.

Description

technical field [0001] The invention relates to an elevator as defined in the preamble of claim 1 . Background technique [0002] One of the goals of elevator research and development work is to achieve efficient and economical use of building space. In recent years, this research and development work has, among other things, resulted in a variety of machine room-less elevator solutions. Some good examples of machine room-less elevators are disclosed in the specifications EP 0 631 967 (A1 ) and EP 0 631 968 . The various elevators described in these technical specifications are quite efficient in terms of space utilization, since they already make it possible to dispense in buildings with the space required for the elevator machine room without enlarging the elevator shaft. In the various elevators disclosed in these specifications, the machine is compact in at least one direction, but in other directions it may have much larger dimensions than conventional elevator machin...
