ELEVATOR-ROPE REEL, ELEVATOR SYSTEM, AND METHOD FOR INITIATING A ROPE-LIKE COMPENSATION WEIGHT WHEN EXTENDING A CLIMBING ELEVATOR

摘要

An elevator-rope reel (1) is described, as can be used in particular for initiating a rope-like compensation weight when extending an extendable elevator system in the form of a climbing elevator. The elevator-rope reel (1) comprises a reel (3) and an elevator rope (5) wound up on the reel (3). The reel (3) also has a reel core (9) extending in an axial direction (7). Furthermore, the reel (3) has, at opposite ends, in the axial direction (7), of the reel core (9), in each case one smaller lateral boundary (11) extending in a plane transverse to the axial direction. The reel (3) also has, at opposite ends, in the axial direction (7), of the reel core (9), and located for example further out in the axial direction (7) with respect to the smaller lateral boundaries (11), in each case one larger lateral boundary (13) extending in a plane transverse to the axial direction (7). The larger lateral boundaries (13) have a larger diameter (D2) than the smaller lateral boundaries (11). The larger lateral boundaries (13) are in the form of separable components on the elevator-rope reel (1). In order to extend the climbing elevator, a previously employed weight compensation chain (39) can be replaced by the elevator rope (5) acting as a weight compensation part (31). Here, a first part-length of the weight compensation rope (31) can be unwound from the elevator-rope reel (1) and suspended on the elevator car (23) and the counterweight (25). Subsequently, the elevator-rope reel (1), following removal of the larger lateral boundary (13), together with a part of the weight compensation rope (31) remaining thereon, can be fastened to the counterweight (25) in a space-saving manner.
