Abstract (en)
[origin: EP1873111A1] An objective is to provide an elevator hoist apparatus that can resolve a problem in which acceleration for stopping a car increases when the braking characteristics of a brake decrease or malfunction occurs that the brake itself does not effectively drive, and can also prevent the increase of an installing space and the increase of the number of parts. The elevator hoist apparatus includes a hoist 1; a sheave 2 fixed to the output axis of the hoist 1; a speed detector 3 for detecting the output-axis rotation speed of the hoist 1; a rope-guard braking means 6 that functions as a rope guard of the sheave 2 or a deviation sheave 5 in the normal operation, and functions as a breaking means in an emergency; and a control means 14 for detecting abnormality, due to over speed, from the rotation speed detected by the speed detector 3, and for operating the rope-guard braking means 6.
