Problems solved by technology

The result is good frictional traction, but one problem with these solutions is that the bending of the rope stresses the rope which wears the rope and thus shortens the life of the rope

Embodiment Construction

[0031] figure 1 Shows a schematic simplified view of a typical traction sheave elevator comprising an elevator car 1, a counterweight 2 and installed between them an elevator roping formed by elevator ropes 3 parallel to each other . The elevator rope 3 is guided around a traction sheave 4 which is rotated by the hoist of the elevator in a groove adapted to the size of the elevator rope 3 . When the traction sheave 4 rotates, the traction sheave 4 simultaneously moves the elevator car 1 and the counterweight 2 in an upward direction and a downward direction due to friction.

[0032] The rope force T exerted on the elevator rope 3 due to the difference between the counterweight 2 and the load in the elevator car 1 plus the elevator car at any given time CTW and T CAR There are different magnitudes on different sides of the traction sheave 4 . When the elevator car 1 contains a load of less than half the rated load, the counterweight is usually heavier than the elevator car ...

Abstract

The object of the invention is a method for modernizing an elevator, and a traction sheave elevator, which elevator comprises at least an elevator car (1) and a traction sheave (4) that moves the elevator car (1) by means of elevator ropes (3), the rim of which traction sheave comprises one or more rope grooves (8). In connection with modernization a traction sheave is installed as the traction sheave (4) of the elevator, the rope grooves (9) of which traction sheave (4) comprise a material, the frictive traction achieved by which is greater than the frictive traction between the parent material of the metallic traction sheave and the elevator ropes (3).

Description

technical field [0001] The object of the invention is a method for manufacturing or modernizing a traction sheave elevator as provided in the preamble of claim 1 and a traction sheave elevator as provided in the preamble of claim 15 . Background technique [0002] The modernization of prior art elevators generally focuses on elevators that no longer meet the requirements of the times, technically and / or otherwise. A modernization may focus on a few sub-functions or subsystems, or at its maximum may mean a complete or substantially complete renewal of the elevator. Things that may be modernized include, inter alia: the elevator's control system; the elevator's hoisting function by means of machinery and roping; the elevator doors; and the elevator car. On the other hand, the maintenance program of the elevator maintains the existing systems and functionality of the elevator. Thus, it is normal that when the hoisting ropes have worn out they are replaced by new hoisting rope...
