Kaishan Surface Drilling Rigs/Mid-size Crawler DTH Drill Rig Series
KG520
The KG520/KG520H surface DTH drilling rig is an improved device in compliance with national regulations on diesel-engine emissions. Equipped with the Yuchai four-cylinder engine, the drill rig meets national standards for emissions and environment. The folding frame track and four-wheel drive are adopted; track leveling and the plunger-piston walking motor improve the working pressure and climbing capacity. The expanded pitch and lifting-arm hydraulic cylinder enable it to meet the requirements of limiting position. The rotary torque and revolving speed are raised; the propulsion motor and chain are used to raise the lifting force and reliability. The dust collector is enlarged to produce a better effect on dust collection. The thickened profile folder is used for the housing, thus improving its level of intensity and rigidity; and the additional ring makes handling and lifting convenient.

Recommended packages
Air compressor match
This rig draws 15-22 m³/min at the hammer. Pair it with a KSCY-650/20-700/17T (18-19 m³/min dual-mode 2.0/1.7 MPa) or the next class up, keeping 10-15% flow margin.
DTH hammer & bits
K5/K50 class hammers (135-165 mm) suit the Φ105-152 mm range of this model — confirm the hammer pressure rating against your compressor before ordering.
