Abstract:
1. A traveling system for an engineering machine comprising: an engine; an accelerator pedal that indicates a basic target speed of the engine; a travel device driven by the engine; a multi-speed motive power transmission provided on the travel device; gear selection means for selecting a gear of the motive power transmission; a front work device provided at a vehicle front of the engineering machine for implementing work by using an output horsepower of the engine; vehicle speed detection means; and engine control means for limiting a maximum engine speed to a preset first engine speed limit (Ncmax1) lower than a maximum rated engine speed, while the gear selection means is selecting a required gear that is either the highest gear or the next highest gear, when an actual vehicle speed detected by the vehicle speed detection means approaches a preset vehicle speed limit (Scmax).
