METHOD FOR MANUFACTURING OR MODERNIZING A TRACTION SHEAVE ELEVATOR, AND TRACTION SHEAVE ELEVATOR

摘要

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).
