Operational assistance system for obstacle collision avoidance and load sway suppression in overhead traveling crane

This paper discusses the development of an operational assistance system in an overhead traveling crane. In the crane operation, the skill with obstacle collision avoidance, suppression of the load sway, and transferring to the target position in a short time is required. However, it is difficult to acquire the skill in the practical field. Therefore, the operational assistance system for avoiding the obstacles collision and suppressing the load sway is proposed in this paper. The proposed system is realized by the system integration of the environment recognition system and joystick system with reaction force display. And, the load sway can be suppressed by the filtering approach. The effectiveness of the proposed system is verified by the experiments with the laboratory-type overhead traveling crane.
