01
Use its single engine to drive the screw air compressor and hydraulic system. Compared with split drilling rigs, comprehensive fuel consumption is reduced by 35%, and maintenance costs are reduced by 50%;
02
The key hydraulic components are imported from Europe, and the reliable hydraulic system greatly reduces the workload of maintenance and improves availability;


03
The powerful two-speed hydraulic tramming mechanism, excellent off-road capability, the high-torque rotary motor can easily cope with complex formation drilling and drilling string jamming;
04
The configuration of the two-stage dry dust collector is environmentally friendly and also helps to increase productivity; the integrated configuration eliminates the difficulty of air compressor movement and compressed air pipeline handling on construction sites and mines.
