The patented parallelogram articulated structure actualizes a wider working range. The highly strengthened boxtype steel structure design makes the mast of highly-rig-idity and anticontorted, therefore the drill accuracy is heightened. The lubrication-free 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.
■Internationalized Configuration: The main parts are imported from imternational manufacturers:Rexroth
A8VO constant power series with double pumps, motor , pilot proportional control valve, reducer , imported controller , which guarantees its reliability.

Rotating Mechanism |
Rotating Mechanism: Adoption
the imported comported component , large back-up bearing as well the auto-reposition mechanism make the operation easy and save the time. the rotary table rotates 360 degree to release scrap angle.
■ Engine: Equipped with world famous engine , with high efficiency by easy operation . The turbocharged, direct injection engine maximize the power at a optimum fuel consumption. The combination of the high horsepower and the potent hydraulic system guarantees the powerful torque output.
■ Control System: PLC control system realozes the automatic/self verticality for mast. XR Series has automatic pressure inspection and alarm, depth inspection of the drill hole, dynamic and digital display , mast automatic/self erecting and falling , easy and simple in system operation.
