Embodiment Construction

[0055] figure 1 A three-dimensional view is shown of a safety member according to the invention, which is designed to be installed in an elevator shaft. The safety member 1 comprises means 2 for preventing downward movement of the safety member 1 relative to the elevator shaft. The safety structure 1 also preferably comprises a stop element 3 for receiving shocks, such as a general buffer, and is preferably able to absorb shocks if for example a moving elevator car hits the safety structure. The safety member 1 also preferably comprises means 6 for connecting a rope or chain to the safety member, such as anchoring means and / or pulleys for guiding the rope and chain through the safety member. The safety member preferably also comprises guides 4 designed to be fitted against the elongated guide rails to guide the safety member in the elevator shaft. The safety means also preferably comprise clamping release means 5, preferably manual means, for moving the braking part pressed ...

Abstract

An elevator arrangement, comprising at least one elevator shaft, a working platform, elevator car or equivalent arranged to move in the elevator shaft, a power source for moving the said working platform or equivalent e.g. by means of ropes, chains, belts or equivalent, characterized in that the vertical range of movement of the said working platform or equivalent in the elevator shaft has been temporarily delimited in such manner that its movement can only take place in a section of the elevator shaft, by means of a structure (1), preferably a beam, which is mounted in the elevator shaft in the path of the said working platform, elevator car or equivalent, said structure (1) being fitted in the elevator shaft below the said working platform, elevator car or equivalent at a distance from the bottom of the elevator shaft.

Description

technical field [0001] The invention relates to an elevator installation as defined in the preamble of claim 1 , a method as defined in the preamble of claim 13 and a safety component as defined in the preamble of claim 19 . Background technique [0002] During the construction of the elevator, the installation work is carried out in the elevator shaft from a platform or equivalent provided in the elevator shaft. The installation work consists of installing the guide rails in the elevator shaft. The platform is usually movable to allow for changes in working height. In many cases this is done using so-called Tirak hoists, but other types of hoists can also be used. These hoists can move the platform by means of a cable chain (or equivalent, such as a rope) having a lift ratio of 1:1, for example, in a device where the hoist is fixed to the platform and exerts tension on the chain, where the One end of the cable chain is fastened to a beam arranged above the platform in th...
