3. The chassis is mechanical gear shift type.It has high speed, low ground pressure, strong adaptabilityto groundsurface. It meets the demand of vegetation protectionand green construction. And reduces numbers of operator and the safety risk.
4. New model design of power swivel that circulation drilling fluid and bearing chamber are separate reduces damage probability of bearing. Clearance between seals is adjustable, so maintenance interval is long.
5. The drilling rig is equipped with the balance valve and relief valve to ensure steady going up & down with load, improves the reliability and safety of drilling rig.
6. It is also equipped with safety and warning mark to meet the requirement of H.S.E. and improves the level of security of the rig effectively and reduces accident rate.
