Document Type and Number:
Japanese Patent JP4270831
Kind Code:
B2
Abstract:
An elevator system having no machineroom is provided in which a height of a pit in a bottom of an elevator shaft can be reduced, a maintenance operation can be carried out at one on an upper part of the cage, and cage-side sheaves and cage-side guide rails can be disposed symmetrically with respect to the center of gravity of the cage. The elevator system having no machineroom includes a pair of right and left cage-side sheaves 16 L and 16 R disposed above a cage 10 , and a traction sheave 17 disposed behind a cage-side guide rail 11 L. The pair of right and left cage-side sheaves 16 L and 16 R are disposed such that each rotational angle of the pair of right and left cage-side sheaves 16 L and 16 R is extended parallel to a rotational axis of the traction sheave, or extended at a direction angle close to that of the rotational axis of the traction sheave.
