METHOD FOR MODERNIZING A HYDRAULIC ELEVATOR

摘要

A method for modernizing a hydraulic elevator, said hydraulic elevator having a pair of car guide rails (1, 2) on the same wall (4) of a shaft (3) and a hydraulic cylinder (5) placed between said car guide rails (1, 2). In the method, the hydraulic cylinder (5) is removed from the shaft (3). The hydraulic elevator is modernized into a traction sheave elevator provided with a rope- traction machine (6) by a technique whereby the old car guide rails (1, 2) are retained, the new rope-traction machine (6) is installed between the car guide rails in the space between the wall (3) and the path of the car, and the car (8) is suspended on the rope/ropes (7) of the rope- traction machine (6).
