By using this system, an operator can safely keep hovering loads level at prominent spots or on sites where visual operation is impossible. This system consists of a microcomputer-based controller, sensors (boom angle, rope length, boom lever pressure, engine speed and hydraulic actuator. The control algorithm is the combination of criticism and feed backs control. Nonlinear compensation and gain scheduling by engine speed are also additional. The effect of this algorithm was verified by mathematical simulation and investigation trials. We could keep the suspended load level in the accuracy by boom operation and the system has been set to practical use.
