XR220A Rotary Drilling Rig

Performance Characteristics

  1.Adopting the imported tur-supercharged engine with European 3 effluent standard , it has Super-power. The complete machines have passed CE authentication, meet environmental protection and energy conservation as developing requirement.

  2.With the hydraulic pressure svstem adopted threshold power control and positive flow control,the system acquired high efficiency and higher energy conservation.

  3.Adopting intelligent control,CAN bus and PLC control with autonomic knowledge property right, include the automic/self verticality for the mast,depth auto-inspection of the dill hole, engine's'idle speed auto-cont rolled, reposition of auto-controlled, and fault diagnosis of intelligent control, etc.

  4.The special crawler undercarriage with the advanced integrated manufacturing system have super-stability and high structural strength. As adopting heavy hydraulic telescopic crawler, it meets high moving character and easy transportation.

  5.Main and auxiliary winch are easier operation with seted in the back-up flatform. The main winch is provided a freefall hydraulic system for automatic follow during the drill operation.

  6.The patented parallelogram articulated structure actualizes a wider wrok range. The highly strengthened box-type steel structure design makes the mast of highly-rigidity and anticontored, t herefore the drill accuracy is heightened. The lubrication-free bearing are equipped in the flexible articulation joints. So the regular maintenance is unnecessary. Upper structure can slew with 360 degree,and discharge slag at random angle.

  7.A variety of Kelly bars area vailable, six knot Kelly bars can be selected ,and maximum drill depth can reaches 80 m.
