Kaishan Surface Drilling Rigs/Mid-size Crawler DTH Drill Rig Series
KG430
The KG430/KG430H 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 tramming 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 double rotation motor increases the rotary torque and revolving speed; the lifting hydraulic cylinder and chain are expanded to promote the lifting force and reliability. 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.

Key highlights
- ✓Yuchai four-cylinder diesel engine meeting national emission and environmental standards.
- ✓Folding frame track with four-wheel drive for rough ground.
- ✓Track leveling and a plunger-piston tramming motor improve working pressure and climbing capacity.
- ✓Expanded pitch and lifting-arm hydraulic cylinder meet the requirements of limiting positions.
- ✓Double rotation motor increases rotary torque and revolving speed.
- ✓Enlarged lifting hydraulic cylinder and chain increase lifting force and reliability.
- ✓Thickened profile folded housing raises structural strength and rigidity; additional lifting ring eases handling.
Applications: Surface down-the-hole (DTH) drilling of holes from Φ90 mm to 152 mm. · Rock of hardness f = 6-20, at an economical drilling depth of 25 m. · Sites that pair the rig with a portable air compressor: selection depends on hole diameter and air-hose length, and the catalog recommends KSCY650/20-700/17T, KSCY310/22 and KSCY750/20-800/17T.

Recommended packages
Air compressor match
This rig draws 10-17 m³/min at the hammer (3" or 4"). The standard pairing is a KSCY mobile compressor in the 18-21 m³/min class — e.g. KSCY-310/22 (21 m³/min @ 2.2 MPa) or KSCY-650/20-700/17T (18-19 m³/min dual-mode).
DTH hammer & bits
3" and 4" DTH hammers cover the Φ90-130 mm range — K3/K30C class for 90-105 mm holes, moving up a size for 130 mm holes. Matching button bits order as a set.
