ABSTRACT:
A hoisting machine includes a stationary part having a shank and a stationary frame integrally formed with the shank, and a motor stator provided to the stationary frame. A rotary part includes a rotary frame rotatably supported to the shank through a bearing and facing the stationary frame, a sheave integrally formed with the rotary frame on the side opposite to the stationary frame, a motor rotator arranged at the outer periphery of the rotary frame and facing the motor stator, and a brake wheel integrally formed with the rotary frame and having a larger diameter than that of the sheave. A braking device is mounted to the stationary frame and coming in contact with the brake wheel for braking operation.
