Title:
TRACTIVE DEVICE FOR AN ELEVATOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/069571
Kind Code:
A4
Abstract:
The invention relates to a tractive device (208) for an elevator system (103), which can be arranged in a shaft scaffold (102) or a lift shaft (100) and serves to accommodate a load-receiving means (200) which is moved up and down in the shaft scaffold (102) or the lift shaft (100) by means of at least one drive shaft (204) connected to a drive engine (126) and mounted to the shaft scaffold (102) or on the lift shaft (100) and by means of carrying means, especially a tractive device (208). The aim of the invention is to produce the shaft scaffold and the corresponding drive device for an elevator system in a simple and cost-effective manner while ensuring optimum use of space. According to the invention, this aim is achieved by the fact that the tractive device (208) is designed as a pulley block (209) and provided with two or more, particularly four, deflection disks (206, 212, 214, 219), the axes of which are arranged one beneath the other in a plane that extends approximately vertically, wherein at least one deflection disk (206) is mounted in the lift shaft or on the shaft scaffold (102) above the elevator system (103), another deflection disk (219) is arranged beneath the elevator system (103) in the lift shaft or on the shaft scaffold (102) and one or several, especially two, deflection disks (212, 214) are mounted on a side element (202) of the load-receiving means, essentially a drive platform (200).
