ELEVATOR
Document Type and Number:
WIPO Patent Application WO/2004/113218
Kind Code:
A1
Abstract:
An elevator having a machine room where a sufficient workspace required for maintenance and inspection of a hoisting winch, a control board, a speed governor, etc. is secured and not requiring addition of a receiving beam to the building side in order to install the hoisting winch. A drive device (42), a traction sheave (41), and a weight-side rope engagement portion (46) are arranged above one (21L) of a left and right pair of cage-side guide rails. A cage-side rope engagement portion (44) and a speed governor (47) are arranged above the other cage-side guide rail (21R). A control board (48) is positioned along the central part of an inner wall surface (34) behind a machine room (30), and this enables a wide workspace to be obtained in the central part of a floor surface (31) of the machine room (30). Further, a machine beam (53) can be extended across the front/back direction inside the machine room (30), so that additional installation of a building-side beam is not required.
