Title:
MACHINE-ROOMLESS ELEVATOR SYSTEM WITH AN ELEVATOR MACHINE MOUNTED ON AN ELEVATOR CAR
Document Type and Number:
WIPO Patent Application WO1999043595
Kind Code:
A3
Abstract:
A machine-roomless elevator system (10) includes an elevator car (16) propelled by an elevator machine (32) mounted thereon and at least one flat rope (22) for suspending the elevator car (16) and providing traction therefor. Use of flat ropes combined with various roping arrangements reduces the size of the elevator machine (32) required to propel the elevator car (16). Smaller size elevator machines are more practical and result in cost savings for the elevator system (10). Additionally, placement of the elevator machine (32) on the elevator car (16) provides a safer environment for the elevator maintenance crew.
