Introduction:
The HC726 is a tracked drilling rig between a light and heavy DTH rig. Walking hydraulic drill rig, rotation, and change the Angle of drilling. It can be used in combination with medium-pressure portable screw air compressor and medium-high DTH hammer. High performance, affordable, low cost.
 
Features:
 
1.High torque required low speed hydraulic motor drive torque device output drill rig.
2. More stable cylinder thrust and lower failure rate.
3. Double phase filtering device effectively ensures the safety of the diesel engine intake, prolong the service life of diesel engine.
4. Constantly monitor the hydraulic system pressure and propulsion pressure of drilling rigs to ensure the stable and efficient operation of drilling rigs.
5. Adopt domestic famous brand multi-way control valve, excellent performance and convenient operation.
6. Reliable crawler device, ensure the reliability of the drilling rig.
