Title:
MACHINE ROOM-LESS ELEVATOR
Document Type and Number:
WIPO Patent Application WO/2005/118451
Kind Code:
A1
Abstract:
A machine room-less elevator, wherein a balance weight is lifted at the rear of a car and the car and the balance weight are suspended in a hang bottle shape through first and second deflector sheaves. The lifting stroke of the balance weight is secured sufficiently, the durability of a hoist rope is increased, and a difference in tension is not produced between the portions of the hoist rope to prevent the vertical vibration from occurring on the car when the lifting of the car is re-started. A traction sheave is disposed on either of the right and left side-wall sides of a hoistway, the first reflector sheave is disposed on the lower side of the traction sheave apart sufficiently from each other, and the second reflector sheave is disposed at the top of the rear wall of the hoistway. The traction sheave is disposed aslant relative to the side wall so that its rotating axis extends, as viewed from the vertical upper side, from the side wall toward the rear wall of the hoistway.
