INSTALLATION MATERIAL OF WORKING VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide an installation material of a working vehicle which can selectively drive a hydraulic pump with an engine and an electric motor and further can select a power source automatically and precisely according to actual surrounding environmental circumstances on the basis of power source selection information set correspondingly to surrounding environmental circumstances of the working vehicle.SOLUTION: Control devices UK1 and UK2 include: a storage unit C1 which stores power source selection information preset correspondingly to surrounding environmental circumstances of a working vehicle; a power source selection unit C2 which selects a power source on the basis of power source selection information stored by the storage unit C1 and surrounding environmental circumferences of the working vehicle detected by detection means SE1 to SE4; and a switch control unit C3 which switches and controls a power source switching device X capable of selectively switching a power source of a working machine into either of an engine E or an electric motor M such that the power source selected by the power source selection unit C2 becomes the power source of the working machine.
