  • Method for replacing the hoisting roping of an elevator and a traction appliance arrangement used in the replacement
    Patent number: 8112861
    Abstract: The present invention relates to a method and a traction appliance arrangement for replacing the hoisting roping of an elevator, which elevator comprises at least guide rails (10) along which an elevator car (7) provided with safety gear (7a) travels in the elevator shaft in an essentially vertical direction, a hoisting machine (8), a traction sheave (9) and roping (1b). The ropes (1aa) of the new roping (1a) and the ropes (1bb) of the old roping (1b) are joined to each other by splicing the ropes (1aa and 1bb) together at one of their ends and by strengthening the joint by means of compressive sleeves (4, 4a), after which the new roping (1a) is pulled into position by means of the old roping (1b) and the hoisting machine (8) of the elevator.
