CARGO VEHICLE
A cargo vehicle includes a hydraulic pump (9) driven by an engine (8), a cargo handling apparatus (2) operated by hydraulic oil from the hydraulic pump, a cargo operating unit (12, 13) for performing an instruction operation to operate the cargo handling apparatus, an electromagnetic proportional control valve (14, 15) disposed between the hydraulic pump and the cargo handling apparatus, a valve controller (22) that controls the electromagnetic proportional control valve depending on an operation state of the cargo operating unit, and a revolution detector (20) that detects a revolution of the engine, wherein the valve controller controls the electromagnetic proportional control valve such that an opening degree of the electromagnetic proportional control valve is limited for a certain time when the revolution of the engine detected by the revolution detector is lower than a predetermined value.
