A study on the development of the engine/hydraulic pump control system of excavator

굴삭기의 엔진 및 유압펌프 제어시스템의 개발에 관한 연구

According to the recent increase of demands for multi-function and economics on hydraulic excavator, it is required that excavator should have simple operation, higher and operational efficiency. However, it is difficulty for current hydraulic system to satisfy demands fully. This study shows that new control system improves power transmission efficiency, work capability of engine and hydraulic system of current excavator.
