Problems solved by technology

The disadvantage of an elevator equipped with a counterweight is the cost of the counterweight and the space it requires in the shaft
Roller elevators, rarely used today, have the drawback of being heavy and large complex lifting machines requiring high energy consumption

Embodiment Construction

[0064] figure 1 A schematic diagram representing the structure of an elevator. The elevator is preferably an elevator without a machine room, the drive machine 10 being installed in the elevator shaft. The elevator shown in the figure is a traction sheave elevator without counterweight and with the machine above. The running of the elevator hoisting rope 3 is as follows: one end of the rope is immovably fixed to the anchor seat 16 on the upper part of the shaft, so that the rope 3 goes further to the diverting pulley 15 placed on the upper part of the shaft and thus the diverting pulley 15 goes further to be placed on the elevator car The diverting pulley 13 above the car, from which it goes further upwards towards the traction sheave 11 of the drive machine 10, passing around the traction sheave along its grooves. From the traction sheave 11, the rope 3 further passes down the elevator car 1 that moves along each guide rail 2 of the elevator and moves toward the diverting p...

Abstract

An elevator, without counterweight and preferably without machine room, in which the hoisting machine (10) engages hoisting ropes (3) by means of a traction sheave (1), the elevator car (1) being at least partly The ground is supported by the hoisting ropes used as means for moving the elevator car (1). The elevator car is suspended on the On the hoisting ropes (3), and in this elevator, each guide rail (2) is arranged on one side of the elevator car (1).

Description

technical field [0001] The invention relates to an elevator as defined in the preamble of claim 1 . Background technique [0002] One of the purposes of elevator development work is to obtain efficient and economical utilization of building space. In recent years, this development work has produced, among other things, a wide variety of elevator solutions without a machine room. Good examples of elevators without a machine room are described in technical specifications elevator EP0631967 (A1) and elevator EP0631968. The elevators described in these 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 elevators set forth in these technical specifications, the machine is compact in at least one direction, but may have much larger dimensions than usual elevator machines in other directions. [0003] Among thes...
