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.
