This invention provides a traveling system for an engineering machine, adapted to limit a maximum traveling speed of the machine without causing decreases in engineering work efficiency or in accelerating performance during a start of traveling, and to improve fuel efficiency by suppressing a loss of engine output horsepower under the limited state of the maximum traveling speed. During fourth-gear shift control process, capacities of first and second hydraulic motors 23, 24 are controlled in coordinative form and the second hydraulic motor 24 has its minimum tilting amount limited to a tilting amount limit q2cmin. In addition, when a tilting amount of the first hydraulic motor 23 reaches a minimum tilting amount q1min, the engine 10 has its maximum engine speed limited to a first engine speed limit Ncmax1 (e.g., 1,800 rpm).
