Kaishan DTH Drilling Rigs
Heavy-duty surface crawlers and integrated rigs for open-pit mining, quarry blasting, and slope stabilization. High penetration rate and anti-jamming hydraulic system.
EQUIPMENT CATEGORIES
Equipped with a motor-driven heavy roller chain feed system providing an extended 4,150 mm stroke. Perfectly handles 3-meter drill rods (Φ76 mm or Φ89 mm) with generous tool clearance to accelerate rod-changing cycles.
Powered by a turbocharged Yuchai YC4DK100-T304 engine (73.5 kW / 100 HP @ 2200 rpm), satisfying national Tier 3 off-road emissions standards while providing substantial hydraulic power reserves for severe rock conditions.
Boasts an exceptional 440 mm ground clearance and dual plunger travel motors achieving tramming speeds up to 4.0 km/h. Combined with ±10° track leveling, it easily conquers 30° slopes and rough rock obstacles.
The KG520H configuration is equipped with an enlarged multi-element cyclone dust extraction system, providing superior dust collection capacity during high-speed production drilling in ⌀105–152 mm boreholes.
