Abstract:

Skilled rough terrain crane operators say that they take many sensory information for getting more precise movements of a machine. The first experiment in this paper reveals which sense is the most important factor for crane operation. By using a 25ton crane simulator, (visual, acoustical and tactile) information of an actuator speed was given to operators so as to assist their operation of stopping the load oscillation. The best result, both the task performance and the sensory evaluation of the operating feeling, is got by using the visual information feedback method. Then a new multi- display system is proposed that enables a crane operator to lessen the load oscillating amplitude very easily by adjusting the actuator operation lever position to the oscillating load position. (Patent pending) The second experiment demonstrates the effectiveness of this new multi-display system.
