- High slag discharge wind speed ensures clean hole bottom with no secondary crushing
- No liquid column pressure improves hole bottom crushing condition without groundwater interference
- High-frequency impact drilling method reduces influence of hole inclination on rock or inclined stratum
- Improves drilling hole verticality and reduces rock collapse of hole wall
- Requires significantly less WOB and torque compared to rotary well drilling rigs
- Reduces equipment mass and capacity requirements for large-diameter hard rock drilling
- Excellent adaptability to work under various complex rock strata including aquifers
- Simple structure with convenient use and maintenance
- Excavator crawler chassis for superior off-road performance
- Independent module design allows mounting on trucks for increased maneuverability
- Two-speed swing and propulsion speed to meet different piercing needs of stratum and rock formation
- Combined positioner adjusts and replaces positioning plate according to different drill pipe and impactor types
- Ensures accurate and reliable positioning and centering
- Hoisting mechanism facilitates lifting of drill pipe and impactor to reduce labor intensity
