Abstract
Provide is a loading vehicle capable of quickly operating an object handling device in the upward direction while traveling forward.A wheel loader 1 comprises an engine 3, an HST pump 41, an HST motor 42, a forward/reverse changeover switch 62, a step-on amount sensor 610, a pressure sensor 73, and a controller 5. In a case where a specific condition for specifying lifting operation of a lift arm 21 during forward traveling of the vehicle body is satisfied, the controller 5 increases maximum rotational speed of the engine to a predetermined value Nmax2 which is greater than maximum engine rotational speed Nmax1 during traveling on the flat ground, and limit maximum vehicle speed to a predetermined value Vmax2 which is smaller than maximum vehicle speed Vmax1 prior to the lifting operation of the lift arm 2.
