I. MainConfiguration:
1. 3500×550 walking caterpillar;
2. Engineering machinery Engine(239KW) made by Dongfeng Cummins;
3. Closed hydraulic system- variable piston pump made by Am. Sauer, hydraulic motor and wash valve made by SAM(Italy) or Am. Sauer;
4. Planetary reducer made by DANAMIC (Italy) or KPM (Germany);
5. Large module alloy steel rack and pinion;
6. Electricity proportional control system made by Am. Sauer;
7. Wire-controlled walking system;
8. Mechanized rod-install system;
9. 2T crane.
II. Main Performance Characteristics:
1. Hydraulic system: closed push-pull, rotary and walking system, electricity proportional control;
2. Clamp separately floating;
3. Push-pull transmitted by rack and pinion;
4. Main axle is floating that is preferable for the rod thread;
5. Electricity controlled handle made by Am. Sauer, the circuit layout is plain, but reliable and sensitive;
6. Safe wire-control walking system;
7. Mechanic rod-install system, which is efficient but requires less manual work.
