Abstract

In the hoist (23), a stator side housing (6a) to which a brake arm (7) is fixed opens around a shaft pin (9a) for the rotor side to which a sheave (8) and a brake drum (8g) are fixed. When the housing (6a) is opened, a fixing bolt (8d) is inserted into an engaging rod (8a) which moves upward to unlock the lock (13) of the housing (6a). In this regard, the brake drum (8g) is secured not to rotate by inserting the distal end of the engaging rod (8a) into the screw hole (8k) of the brake drum (8g). Furthermore, a sheave fixing confirmation switch (15) located above the engaging rod (8a) is pushed by inserting the fixing bolt (8d) and moving the engaging rod (8a) upward. Consequently, power supply to the hoist (23) is interrupted and the brake drum (8g) is stopped not to start rotation. Maintenance and inspection work of the hoist (23) is thereby facilitated and safety is enhanced.
