Climbing elevator with mechanism for extending ropes

(Contributing to shortening of construction period and resource conservation by reducing rope waste)

Abstract

Recently, efforts to reduce construction costs and improve work efficiency have been accelerating. As one solution to shorten construction periods, various elevator companies have adopted the "climbing elevator" system. As our conventional system needs to replace the suspension ropes during the climbing operation, reducing the downtime of the elevator during the climbing operation is a key issue to solve. Therefore, to address this issue, we developed a compact machine room unit which contains climbing equipments and rope feeding devices. This paper particularly focuses on a rope tension balance mechanism while feeding multiple ropes and suspension balance evaluation to suppress the guide reaction force of the machine room unit during the climbing operation.
