ABSTRACT:
Provided are an engine111, a generator-motor113, a clutch112connecting/disconnecting power therebetween, a battery115, and a loading pump117for driving a fork118. The generator-motor113is set either in a generator mode or in a motor mode. When a cargo handling load (detected by a loading lever position sensor145and the like) is smaller than a predetermined value, the clutch112is set to a disconnection state, the engine111is stopped or idled, and the loading pump117is driven by the generator-motor113in the motor mode. When the load is increased to the predetermined value or more during cargo handling work in a state where the clutch112is released, an increase of the number of revolution of the engine is started while an output of the generator-motor113is being increased. When the number of revolution of the engine111is made equal to the number of revolution of the generator-motor113, the clutch112is set to a connected state, and the loading pump117is driven by the engine111.
