Document Type and Number:
Japanese Patent JP2014122098
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent a working machine from operating unexpectedly due to switching of a driven state of a hydraulic pump by keeping the driven state before switching operation when power source selection switches are operated for switching while the hydraulic pump is either in an engine driven state or a motor driven state in a loaded article of a work vehicle in which the hydraulic pump can be selectively driven by an engine and an electric motor.SOLUTION: Control devices UK2 and UV capable of switching a state of a hydraulic pump P over between an engine driven state and a motor driven state invalidate operation inputs and keep the driven state before switching operation when power source selection switches M-SW1 and M-SW2 are operated for switching in whichever state the hydraulic pump P is the engine driven state or the motor driven state.
