LOADED ARTICLE OF WORK VEHICLE

摘要

PROBLEM TO BE SOLVED: To reduce development cost and development time while enabling a hydraulic pump to be selectively driven by an engine and an electric motor in a loaded article of a work vehicle.SOLUTION: A loaded article-side control device UK includes a second control device UK2 provided between the loaded article-side control device UK and a vehicle-side control device UV in addition to a first control device UK1 for working machine control. The second control device UK2, cooperating with the vehicle-side control device UV, can control a state of a hydraulic pump P to be switched over between an engine driven state and a motor driven state depending on operation inputs to power source selection switches M-SW1 and M-SW2. For switching control of both of the driven states, signal input/output units are provided in the second control device UK2 for inputting/outputting all signals to be transmitted/received between the loaded article-side control device UK and the vehicle-side control device UV to/from the loaded article-side control device UK.
