XR Series Rotary Drilling Rig Technical Features:
XR Series Rotary Drilling Rig stands for our company's achievement in many years' development and
researches on piling machine , adopting the advanced technoloty, both at home and abroad. With our company's powerful machinery manufacturing capacity , it is specially designed to drill the pile hole with the big diameter and into hard-layers, fitting for layer conditions in most areas. XR series is an ideal equipment widely applied in piling constructions, featuring reasonable design, compact structure, convenient operation , high reliability, powerful performance and wide application.
Retractable Undercarrige

Retractable Undercarrige: With telecopic crawler undercarriage, it meets high stability and easy transportation. Adoping the imported Cummins turbine-charged engine,make it competent for operating on plateau. Noise emission meets with the national standard. Constant power output assures an excellent working performance.




Rotary Drive
Rotary Drive: XR Series is featured with unique slewing bearings double reducer transmission mechanism, powerful output torque , spinning off up to 130 rpm. Particular lubrication system guarantees the lubri-cation and radiation so as to extend rotary table's service life.
Working Devices:
Rotary Drive
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.
Internationalized Configuration

Main and Auxiliary winch: The main winch is provided with a freefall hydraulic
Main and Auxiliary winch
system for automatic follow during the drill operation . It also has a auto-tightening function in the quick freefall.
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.
