Kaishan Surface Drilling Rigs/Compact Crawler DTH Drill Rig with Integrated Air Compressor Series
ZT12
The ZT12 integrated surface DTH drilling rig can drill vertical, inclined and horizontal holes, and is mainly used for open-pit mines and stonework blast holes and pre-splitting holes. It is driven by a Cummins non-road diesel engine, and the screw compression system and hydraulic transmission system are simultaneously driven by the back-end flywheel and PTO port output. The drill rig is equipped with an automatic rod handling system, a drilling rod floating slide module, a drill pipe lubrication module, a drill pipe sticking prevention system, a hydraulic dry dust collection system and an air-conditioning cab, with optional drilling-angle and depth indication function. The drill rig is characterized by excellent integrity, high automation, efficient drilling, environment-friendliness, energy conservation, simple operation, flexibility and travelling safety.

Key highlights
- ✓Single Cummins diesel engine drives both the on-board screw compressor (rear flywheel output) and the hydraulic transmission (PTO output).
- ✓Automatic rod handling system, drilling rod floating slide module and drill pipe lubrication module.
- ✓Drill pipe sticking prevention system.
- ✓Hydraulic dry dust collection system.
- ✓Air-conditioned cab with optional drilling-angle and depth indication.
- ✓Can drill vertical, inclined and horizontal holes.
- ✓Excellent integrity, high automation, efficient drilling, environment-friendliness, energy conservation and travelling safety.
- ✓Drill rod thread automatic oil-spraying lubrication.
- ✓Mechanical floating protection for rod threads.
Applications: Open-pit mines and stonework, for blast holes and pre-splitting holes. · Vertical, inclined and horizontal holes of 115-152 mm at an economical drilling depth of 32 m. · Integrated rig: on-board two-stage screw compressor supplies 20 m³/min at 22 bar, so no separate air compressor is needed.

Recommended packages
Air compressor match
Integrated rig — the screw air compressor is built into the machine, so no separate compressor unit is needed. Only confirm the onboard compressor rating (pressure and flow) matches your hammer size.
DTH hammer & bits
Match the DTH hammer class to your hole diameter: K3/K30C for 90-105 mm, K5/K50 for 135-165 mm — see the DTH hammer series page for the full ladder.
