る荷役車両の油圧機構。 A hydraulic pump that is driven by an engine and sends hydraulic oil from a supply source, a hydraulic cylinder that is operated by hydraulic pressure, a first oil passage that supplies hydraulic oil from the hydraulic pump to the hydraulic cylinder, and a first oil passage that is provided on the first oil passage. the switching valve, and a second oil passage that returns hydraulic oil from the switching valve to the supply source, and the switching valve switches the flow of hydraulic oil sent from the hydraulic pump to either the hydraulic cylinder or the supply source. In the hydraulic mechanism of a cargo handling vehicle that drives and stops a hydraulic cylinder, a hydraulic pressure detecting means for detecting the hydraulic pressure in the first oil passage from the hydraulic pump to the switching valve is provided, and the hydraulic pressure is determined based on the detection information of the hydraulic pressure detecting means. A hydraulic mechanism for a cargo handling vehicle, characterized in that the rotation speed of the engine is increased in response to an increase in oil pressure in a first oil passage when a cylinder is driven.
