A construction vehicle includes an engine, a hydraulic pump configured to be driven by the engine, a traveling hydraulic motor configured to be driven by pressured oil discharged by the hydraulic pump, a traveling wheel configured to be driven by driving force of the traveling hydraulic motor, and a control unit configured to control a vehicle velocity and a traction force by controlling rotation speed of the engine, capacity of the hydraulic pump, and capacity of the traveling hydraulic motor. In addition, the control unit is further configured to perform slip reduction control for reducing the maximum rotation speed of the engine as the vehicle velocity becomes slow in a low-velocity range in which the vehicle velocity is less than or equal to a predetermined velocity.
