CARGO HANDLING WORK VEHICLE
Provide is a loading vehicle capable of improving work efficiency by adjusting engine rotational speed with high accuracy in accordance with an operation state of the working device.An HST traveling driven wheel loader 1 including an electrically controlled HST pump 31, comprising: a controller 5 configured to control input torque of the HST pump 31; and a solenoid proportional pressure reducing valve 36 configured to generate control pressure for controlling displacement volume of the HST pump 31 based on a control signal output from the controller 5. The controller 5 is configured to calculate the displacement volume q of the HST pump 31 based on discharge pressure Pf of a loading hydraulic pump 32 so that maximum input torque Thst of the HST pump 31 decreases as the discharge pressure Pf or input torque of the loading hydraulic pump 32 increases, and output a control signal corresponding to the calculated displacement volume q to the solenoid proportional pressure reducing valve 36.
