Document Type and Number:
WIPO Patent Application WO/2008/032527
Kind Code:
A1
Abstract:
[PROBLEMS] A hoist for an elevator, adapted for installation in different orientations. [MEANS FOR SOLVING PROBLEMS] The hoist (5) has an electric motor (6), a sheave (8), and a brake (10) that are arranged in series. The brake (10) has a brake drum (14) coupled with the electric motor (6), brake arms (16a, 16b) rotatably supported and having brake members (15a, 15b) engaging the brake drum (14), brake springs (18a, 18b) for pressing the brake members (15a, 15b) against the brake drum (14), and brake release means (20a, 20b) for driving the brake arms (16a, 16b). A substantially L-shaped projection plane is formed by the electric motor (6) and the brake arms (16a, 16b). The brake release means (20a, 20b) are arranged side by side along the direction of extension of the brake arms (16a, 16b). The height of the brake (10) is set smaller than that of the electric motor (6). The construction enables the electric motor (6) and the brake (10) to be used with them rotated 180 degrees in any direction about the output shaft (9) of the electric motor (6).
