2. The main characters

- Use rack and pinion instead of cycle-chain, thus the power will not loose during push-pull. also rack and pinion system is high efficiency and convenient for maintain.

-The main componets are from American top brand. which ensure the rig quality and the performance in project site.

- The layout of the oil tube is reasonable and clear, which enhance the structure of the chassis;

- The moving of the power head makes the loading and unloading of driling pile more conviently and also can effectivly protect the screw thread of the dill rod ;

-The spindle rotation and push-pull of the power head adopts closed loop, which can reduce the oil temperature and the wear. Other assistant mechanical adopts open loop driven by high pressure gear pump;
