Main Technical Data of XR220A Multi-funtional Combined Rotary Drilling Rig |
|
■ Performance Characteristics(XR220A)
■ Adopting the imported tur-suppercharged engine with European III effluent standard, it has super-power. The complete machines have passed CE authentication, neet environmental protection and energy conservation as developing requirement.
■ With the hydraulic pressure system adopted threshold power control and positive flow control, the system acquired high efficiency and higher energy conservation.
■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-controlled, reposition of auto-controlled, and fault diagnosis of intelligent control, etc.
■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.
■Main and auxiliary winch are easier operation operation with seted in the back-up flatform,. The main winch is provided a freefall hydraulic system for automatic follow during the drill operation.
■The patented parallelogram articulated structure actualizes a wider work range. The highly strengthened box-type steel structure design makes the mast of highly-rigidity and anticontored,therefore bearings 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.
■A varirty of Kelly bars area vailable, six knot Kelly bars can be selected, and maximum drill depth can reachesw 80 m.
