Abstract
Roping method and apparatus for replacing, installing and/or re-roping the hoisting rope of a traction sheave elevator, said elevator having an elevator car, which is at least partially suspended on a set of hoisting ropes, said set of ropes comprising one or more parallel ropes. The elevator car is moved by means of the ropes. In the method, a rope feed apparatus (1) acting on the hoisting rope is used to feed a new rope to the elevator and/or to pull out a possible old hoisting rope to make place for the new rope. The rope feed apparatus 1 (1) comprises at least a base (2) with at least one feed disc (30, 31) mounted on it, which feed disc (30, 31) engages the hoisting rope and to which feed disc (30, 31) the hoisting rope can be fitted, at least one guide roller (25) for keeping the hoisting rope in position on the feed disc (30, 31), a tightening element (19) for moving the feed disc (30, 31) relative to the guide roller (25) and tightening it in position on the base (2), and in addition at least one electric motor (27) fitted in the apparatus to rotate the feed disc (30, 31).
