Rotary Drilling Rig XR160
Product Description :
XR Series Rotary Dring Rig stands for our company’s achievement in many years devel opment and researches on piling machine,adopting the advanced technology, both at home and abroad.With our company’s powerful machinery manufacturing capacity, it is specially designed to drill the pile holr 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 construtions,featuring reasonable design, compact structure, conveniemt operation, high reliability, powerful performance and wide application. Retractable Undercarrige With telespoic crawler undercarriage,it meets high stability and easy transportaion. 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 130 rpm. Particular lubrication system guarantees the lubrication and radiation so as to extend rotary table’s service life. 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 erectinh and falling, easy and simple in system operation. Working Devices 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 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 international manufacturers: Rexroth A8VO constant power series with double pumps,motor,pilot proportional control valve, reducer, imported controller, which guarantees its reliability. 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. Rotating Mechanism Adoption the imported component,large back-up bearing as well as the auto-reposition mechanism make the operation ersy and save the time. The rotary table rotates 360 degree to release scrap at any angle. Main and Auxiliary winch The main winch is provided with a freefall hydraulic system for automatic follow during the drill operation. It also has a auto-tightenoing function in the quick freefall. Kelly bar and Drilling tool A variety of Kelly bars and drilling tools are available, catering for the different work conditions.
