CONTROL SYSTEM IN WORKING MACHINE

PROBLEM TO BE SOLVED: To cope with a case of desiring to increase power in a working machine, while preventing an increase in consumption torque as the whole working machine, in the working machine provided with main pumps supplied with torque from an engine and an exclusive pump supplied with torque from an accumulator. SOLUTION: This control system is constituted for performing both controls of torque limiting control for limiting so that torque of totaling supply torque to the first and second main pumps and supply torque to the exclusive pump, does not exceed a value of allowable torque TA preset as torque suppliable to the first and second main pumps from the engine, and power-up control supplying torque suppliable to the first and second main pumps and the exclusive pump without limiting.
