PURPOSE:To improve work efficiency by automating the swing stop control of a suspension load. CONSTITUTION:A two-step acceleration timing inference section 1 outputs the optimum two-step acceleration timing for the rope length at a start point and an end point to an operating pattern generation section 2 based on the fuzzy theory. The operating pattern generation section 2 outputs the turn/tilt motion timing of a jib crane to a motor command section 3. The motor command section 3 outputs the time series turn motor control signal determining the operating speed pattern of the jib crane to a turn motor 4 and outputs the time series tilt motor control signal to a tilt motor 5.
