WORKING CONTROL DEVICE IN WORKING VEHICLE
A working control device comprises an operation lever for making a boom cylinder (36), an arm cylinder (37) and others work to drive a shovel apparatus (30), and a delivered oil amount control device (a controller (150)). A working oil supply source includes a first electric motor (M1) and a first hydraulic pump (P1). When the operation lever is subjected to a single operation, a number of the motor revolution based on the lever operation is set to control the first electric motor. When the number of motor revolution is less than a necessary minimum number of revolutions, the necessary minimum number is set to control the first electric motor (M1). When the operation lever is subjected to a composite operation, a total number of motor revolutions based on the lever operations is set. When the total number is less than a necessary minimum number of revolutions, the necessary minimum number is set to control the first electric motor (M1).
