XCMG XR280C Rotary Drilling Rig

XCMG XR280C Rotary Drilling Rig XR280C rotary drilling rig is equipped with CAT336D elongated chassis with super stability. The chassis has high structural strength and heavy-duty hydraulic retractable tracks for easy transport and superior travelling performance. It adopts special extra large horsepower C9HHPRPM, EPATierIII emission standard, which meets the emission requirements of Europe, North America and other countries. The oil cooler and radiator are placed side by side behind the intercooler for good heat dissipation, the fan is driven by hydraulic motor and the fan speed is controlled by piston pump, the wind noise meets the noise control requirements. It is quieter and more environmentally friendly.

XR280C is equipped with CAT336D extended chassis with superb stability. The chassis has high structural strength and heavy duty hydraulic retractable tracks for easy transport and superior travelling performance. Adopting (special extra large horsepower) C9 HHP RPM, EPA Tier III emission standard, meeting the emission requirements of Europe, North America and other countries.

-Oil cooler and radiator are placed side by side behind the intercooler for good heat dissipation, fan is driven by hydraulic motor, fan speed is controlled by piston pump, wind noise meets the noise control requirements. It is quieter and more environmentally friendly.

The main coil wire rope adopts single-layer winding, which is easy and comfortable to operate and improves the mission of wire rope use.

-The hydraulic main system adopts negative flow control, on the basis of which total power control and limit power control are superimposed, which improves the system efficiency and fully utilises the engine power. The auxiliary system adopts load sensitive control system. To achieve the best match between the pump output power and the load of each working condition, the flow is supplied on demand, and the transmission efficiency of the system is improved to the extreme.

-The power head is operated by a pressurised or lifting hydraulic cylinder system, fitted with a drilling hydraulic motor, a top spring shock absorber, and a flange to top off the rotary bucket. Equipped with a drive sleeve suitable for friction and internal locking drill pipes, and a drill pipe guide frame with bearings.

Applying advanced intelligent control technology, CANBUS technology and virtual instrumentation technology, it adopts highly reliable controller and colour LCD monitor, the Chinese human-machine interface of the monitor is easy to operate and easy to observe, and it can directly display the verticality of the mast and the depth of the hole, and automatically detect and display the record in real time, and record the faults of the operation process automatically, and the on-line debugging and diagnosis of the input/output signals, as well as the drilling mast limiting position, amplitude limiting position, main and auxiliary winch limiting position, and the drilling mast limiting position. limit, amplitude change limit, main and auxiliary winch limit, filter alarm, maintenance reminder and other alarm information.

-Standardly equipped with centralised lubrication system, more convenient maintenance.
