Rotary Drilling Rig, rotary drilling equipment, drilling rig manufacturers
Retractable Undercarriage: With telescopic crawl undercarriage, it meets high stability and easy transportation. Adopting 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: XR series is featured with unique slewing bearings double reducer transmission mechanism, powerful output torque, spinning off up to 130rpm. Particular lubrication system guarantees the lubrication and radiation so as to extend rotary table's service life.
Hydraulic parts: The main parts are imported from international manufacturers: Rexroth A8V0 constant power series with double pumps, motor, pilot proportional control valve, reducer, imported controller, which guarantees its reliability.
Main and Auxiliary winch: The main winch is provided with a freefall hydraulic system for automatic following the drill operation.
Rotating Mechanism: Adopting the imported components, large back-up bearing as well as the auto-reposition mechanism make the operation easily and saving time. The rotary table could rotate 360o to release scrap at any 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 realizes the automatic/self verticality for the 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.
