| Abstract;Hydraulic-excavators used widely on the construction site have continued to be improved by the necessity of improvement for controllability, energy conservation, speed-up of actuators, and safety. Nachi-Fujikoshi, corp. developed the new load sensing system for hydraulic-excavators of the next generation based on the above-mentioned improvement points. This report describes at first a transition of hydraulic systems on hydraulic-excavators. And there, the problems of the conventional systems are clarified. In addition, new load sensing system is explained comparing with these systems. (author abst.) |
