Document Type and Number:
WIPO Patent Application WO/2023/084721
Kind Code:
A1
Abstract:
This construction elevator is provided with: a compensating-rope reel; a raising/lowering unit; a pulley; a first rope-clasping device; and a second rope-clasping device. The pulley is disposed between the compensating-rope reel and the raising/lowering unit along a compensating rope, and the compensating rope drawn out from the compensating-rope reel is wound around the pulley. The first rope-clasping device clasps, in an openable manner, the compensating rope on the compensating-rope-reel side with respect to the pulley. The second rope-clasping device clasps, in an openable manner, the compensating rope on the raising/lowering-unit side with respect to the pulley. Further, the pulley is supported so as to be able to shift along the raising/lowering course of the raising/lowering unit.
