摘要:
A lifting hook device which can, irrespective of the height of lifting, stably and quickly lift up a load with the load constantly oriented to a certain direction. A lifting hook device comprises a fixed hook (3) for lifting provided to a head section (2a) of a hollow body (2) having an inside maintained airtight, a rotatable hook (5) for suspending a load, the rotatable hook (5) having a shaft section (5a) rotatably supported supported in the body and vertically suspended from a bottom section (2c), a motor (8) for rotating the shaft section (5a) of the rotatable book about the axis of the shaft section through a rotating mechanism (7), an azimuth sensor (10) mounted to the rotatable hook and detecting the rotational azimuth of the rotatable hook, and a control section (11) for controlling rotation of the motor to restrict the orientation of the rotatable hook to a predetermined direction.
