。The rotor axis of the gyro rotor is held in a horizontal position by setting a plurality of hanging wires to have the same hanging length, and in this state, when the gyro rotor is rotated by a driving source,
The direction of the rotor axis of the gyro rotor does not change, and the work machine is held in a constant working direction. When the gyro rotor is rotated and any of the suspension wires is pulled up, the rotor axis of the gyro rotor is tilted, the holding case rotates in a predetermined direction around the suspension axis, and the work machine is rotated. Turn in a predetermined direction. When the working machine reaches a desired turning position, the lifted suspension wire is returned to its original position to maintain the rotor shaft of the gyro rotor in a horizontal position. Then, the direction of the rotor axis becomes constant, and the working machine is held in the desired working direction.

。(Effects of the Invention) According to the present invention, the working direction of the working machine cannot be determined by simply hanging the working machine with a wire, and the working direction cannot be easily changed. This allows you to keep the working direction constant.
The working posture of the working machine can be changed easily and quickly by simply manipulating any wire among the plurality of wires. Moreover, since the structure is simple and the device can be miniaturized, it is extremely easy to transport it to a construction site. Further, the device of the present invention can be widely used in demolition work of high-rise buildings and low-rise buildings by suspending it by a wire of a derrick crane or a crane truck, for example.
