In this study, the analysis of the static and dynamic characteristics of the load-sensitive hydraulic pump control system used in the hydraulic excavator was performed by hydraulic circuit ananlysis program. Thess results was verified by the experimental data of the hydraulic excavtor system. The responses on effective parameters of system at the controllable region and the pressure variation of the pump used in hydraulic excavator system was studied to enhance the static performace of the system. the parameter enhance dynamic sharacteristics was considerd.
