Problems solved by technology

If the compensating ropes are not fastened in the wrong way, there is a great risk of losing the friction on the traction sheave, in which case the whole elevator system will fall into an unbalanced state

Embodiment Construction

[0020] figure 1 A typical elevator roping arrangement used in high-rise buildings is presented in simplified and diagrammatic side view. For clarity only, the upper and lower ends of the elevator installation in the elevator shaft are presented. A typical elevator installation comprises an elevator car 1 and a counterweight 2 traveling up and down guided by its guide rails 16, 16a. For clarity, figure 1 with 10 Only the elevator car guide rail 16 and counterweight guide rail 16a on the side of the car and counterweight are shown in figure 1 In , only the guide rails 16, 16a at the upper part of the elevator shaft are shown. The elevator car 1 and the counterweight 2 are connected together by a bundle of parallel hoisting ropes 3, the first ends of which are fastened to the elevator car 1, or directly into the car 1 Or in the frame-like sling that supports the car 1. For clarity, figure 1 The sling is not shown in this nor in the other drawings. The hoisting ropes 3 are...

Abstract

The invention relates to a method for handling and modernizing ropes in an elevator, which elevator comprises at least an elevator car (1) arranged to run in an elevator shaft along the guide rails (16), a counterweight (2) connected to the elevator car (1) with hoisting ropes (3) from above, a hoisting machinery with a traction sheave (5) above the elevator car (1), and compensating ropes (4) connected between the elevator car (1) and the counterweight through a compensating mechanism (8) at a lower part of the elevator shaft. The old hoisting ropes (3) and compensating ropes (4) are dismantled when the elevator car has been run to the upper part of the elevator shaft without a risk of losing the friction on the traction sheave (5).

Description

technical field [0001] The invention relates to a method for processing ropes in an elevator as defined in the preamble of claim 1 and a method for modernizing ropes in an elevator as defined in the preamble of claim 9 and to a method as defined in the preamble of claim 17 Means for removing compensating ropes and / or hoisting ropes of lifts as defined in the preamble of . Background technique [0002] In tall buildings, elevator hoisting ropes comprising a set of parallel similar wire ropes are very long and substantially thick, and for this reason they are usually very heavy. In addition, in tall buildings, compensating ropes are also required to compensate for the weight of the hoisting ropes. The first ends of the compensating ropes are usually fastened under the elevator car, or directly into the car or into the frame-like car slings supporting the car. The compensating ropes are guided downwards from the car towards the bottom of the elevator shaft where they are pass...
