Abstract:
A cargo vehicle includes a hydraulic pump driven by an engine, a cargo handling apparatus operated by hydraulic oil from the hydraulic pump, a cargo operating unit for performing an instruction operation to operate the cargo handling apparatus, an electromagnetic proportional control valve disposed between the hydraulic pump and the cargo handling apparatus, a valve controller that controls the electromagnetic proportional control valve depending on an operation state of the cargo operating unit, and a revolution detector 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.
