2.  A ball mounted card blessing mechanism replaces the chuck which can carry out without stopping the lever, easy to operate, safe and reliable.

3. Handle concentration, easy operation.

4. It is compact.The drill, water pump and diesel engine are installed on the same base, which occupies a small area.

5. It is light in weight, strong in decomposition and easy to remove .And it can be used in plains and mountains

6. if with crawler mounted, rubber track is with lighter weight,and does not hurt urban road.

7. Electric-start diesel engine reduces the operator's labor intensity.
Mud pump:BW160 mud pump,with bigger flow displacement and pressure,easy maintenance.

8.Optional installation of hydraulic twist tube machine(75-168mm),improve work efficiency and reduce labor costs.

Application:

1. In the general survey and exploration of mineral deposits, especially those of nonferrous metals and rare metals, tunnel drilling is used to trace deposits, to explore geological structures, to delineate ore bodies, to sample and verify.

2. In mine excavation, tunnel drilling technology is commonly used to drill underground observation holes, ventilation holes, drainage holes, gas drainage holes, grouting holes, blasting holes, anchor holes and pilot holes for digging tunnels.

3. In other geotechnical engineering construction fields, the equipment and technology of tunnel drilling can be used for slope reinforcement of dam foundation, treatment of geological disasters, support of deep foundation pit, and underground engineering construction of industrial, commercial, traffic, and other aspects.

4. It is used for the construction of building foundation, workshop foundation, high-speed railway foundation, highway foundation and other rock foundation foundation.
