Optimally designed double swing arm luffing mechanism and optimized hinge point position take account of the construction stability and the transportation convenience at the same time;

It adopts H-type hydraulic retractable crawler chassis dedicated for rotary drillingrigs and large-diameter slewing bearing to ensure superior stability andconvenient transportation;

It adopts imported Volvo engine with strong power, which effectively reducesfuel consumption and use cost;

The hydraulic system adopts load sensing technology with total power controland limit power control, making the hydraulic system more efficient andenergy-saving, independent radiator system provides high heat dissipation efficiency;

The proprietary single-row rope main winch of effectively solves thetwine problem and greatly prolongs the service life of wire rope;

The rotary drive owns normal mode special for soil layers and rock-enteringmode special for rock formations, which improves construction efficiency, the autorotation of rotary drive can achieve continuous adjustments of speed innormal mode and rock-entering mode;

Standard centralized lubrication system makes the maintenance more convenientand improves working reliability.
