Product Description

Top Brand High Quality XR220D Rotary Drilling Rig Machine

Feature

• XR220D is equipped with CAT336D chassis, which has strong stability. The chassis with high-intensity structure adopts heavy duty hydraulic retractable track, which is convenient to transport, and has excellent travel performance. Adopt C9 HHP 261KW@1800RPM,EPA Tier III emission standard, meeting the emission requirements of Europe and North America.
• The oil cooler and radiator are positioned behind the intercooler side by side, which has good heat dissipation. The fan is drove by the hydraulic motor, the fan speed is controlled by the piston pump, and the wind noise meets the noise control requirements, which is quieter and more environmental friendly. 
• The main hydraulic system adopts negative flow control. On that basis, add the total power control and limiting power control, which improves the system efficiency and makes full use of the engine power. The auxiliary system adopts the load sensing control system, realizing the optimal match of the pump output power and the load of each working condition and the supply on demand, which improves the transmission efficiency to the most.
• The drill unit is controlled by a pressurized or drawing hydraulic cylinder system, installed with drilling hydraulic motor, and top spring shock absorber, and equipped with the drive sleeve fit for the friction and internal lock drill rod and the drill rod guide frame with bearings.
• Apply with advanced intelligent control technology, CANBUS technology and virtual instrument technology and adopt
