A loading vehicle, comprising: an engine; a variable displacement traveling hydraulic pump driven by the engine; a variable displacement traveling hydraulic motor connected to the traveling hydraulic pump through a closed circuit to transmit driving force of the engine to wheels; an object handling device provided at a front portion of a vehicle body to be rotatable in a vertical direction; an object handling hydraulic pump driven by the engine to supply hydraulic oil to the object handling device; and an operation device for operating the object handling device, wherein the loading vehicle further comprises: a traveling state sensor configured to detect a traveling state of the vehicle body; an operation state sensor configured to detect an operation state of the object handling device by the operation device; and a controller configured to control the engine, the traveling hydraulic pump, and the traveling hydraulic motor, characterized in that the controller is configured to: based on the traveling state detected by the traveling state sensor and the operation state of the object handling device detected by the operation state sensor, determine whether a specific condition for specifying lifting operation of the object handling device during forward traveling of the vehicle body is satisfied, and in a case of having determined that the specific condition is satisfied, increase maximum rotational speed of the engine to a predetermined value which is greater than the maximum rotational speed of the engine during traveling of the vehicle body on a flat ground with the object handling device being in a non-operating state, and adjust displacement volume of the traveling hydraulic pump or displacement volume of the traveling hydraulic motor so as to limit maximum vehicle speed of the vehicle body to a predetermined value which is smaller than the maximum vehicle speed of the vehicle body prior to the lifting operation of the object handling device. an engine;
