A load-sensitive pump is connected with a first safety valve, first to sixth three-position seven-way proportional valves and a fixed-value pressure reducing valve, and first to sixth pressure compensators are correspondingly connected with the first to sixth three-position seven-way proportional valves; the fixed value pressure reducing valve is respectively connected to the first to sixth pilot handle pressure reducing valves; the throttling small hole is connected with a load feedback pipeline and a main unloading pipeline; the first balance valve group is connected with the first three-position seven-way proportional valve and the first and second driving motors; the balance valve group II is connected with a three-position seven-way proportional valve II, a driving motor III and a driving motor IV; the four-position six-way manual reversing valve is connected with a three-position seven-way proportional valve III, a three-point suspension hydraulic cylinder I and a three-point suspension hydraulic cylinder II; the left span adjusting hydraulic cylinder I and the left span adjusting hydraulic cylinder II are connected with a three-position seven-way proportional valve IV; the third left span adjusting hydraulic cylinder and the fourth left span adjusting hydraulic cylinder are both connected with a fifth three-position seven-way proportional valve. And the three-position six-way hand-operated direction valve is respectively connected with the three-position seven-way proportional valve 6 and the landing leg hydraulic cylinders 1-4. The chassis can realize the stepless adjustment operation of the track gauge.
