Abstract:
A hybrid industrial vehicle performs steering operation and the like during idling stop, without using a complicated mechanism. The hybrid industrial vehicle configured to transmit power of a first electric motor (23) and power of an engine (21) to a drive wheel (34) through a first gear train (32) comprises: a second electric motor (24) actuated when supplied with electric power from a battery (22); a first hydraulic pump (26) supplying pressure oil to a cargo handling hydraulic system; a second gear train (28) interposed among the engine and the second electric motor and the first hydraulic pump and capable of mutual power transmission among the engine, the second electric motor and the first hydraulic pump; a second hydraulic pump (27) supplying pressure oil to a steering hydraulic system; and a third electric motor (25) actuated to drive the second hydraulic pump when supplied with electric power from the battery.
