  • Patent number: 5816098
    Abstract: A lifting load attitude controlling system includes a lifting load pivoting clutch (20) provided between a gyro frame (1) and a gimbal frame (6) for connecting and disconnecting therebetween. Also, a resetting rotating clutch is provided between a resetting rotation driving portion constituted of a resetting oblique rotation driving motor (19) for rotating a gimbal (8) upon returning the gimbal (8) at an initial position and a worm gear, and the gimbal (8) for connecting and disconnecting therebetween. Upon obliquely rotating the gimbal for returning to the initial position, the resetting rotating clutch is placed in the engaged or connected state and the lifting load pivoting clutch is placed in the disengaged or disconnected state. When the resetting rotation driving motor (19) is driven at this condition, a gyro moment is generated upon obliquely driving the gimbal toward the gyro frame (1) (lifting jig 4) via a variable constant torque motor (19) between the gyro frame (1) and a gimbal frame (6).
