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
Operates at 0.40–0.63 MPa working pressure, delivering 27–33 Hz impact frequency with 22J to 44.7J single-blow kinetic energy for rapid downward penetration in hard rock (f=8–18).
Functions as a standalone manual sinker drill for downward bench holes, or mounts onto an optional FT100 telescopic air leg for inclined and horizontal face drilling.
Precision-broached chuck sleeve fits standard Hex 22 mm × 108 mm shank integral drill steels and tapered rods (7°, 11°, 12°), ensuring wide tooling interchangeability globally.
Optimized cylinder clearances limit air consumption to 20–55 L/s (1.2–3.3 m³/min). Few moving parts and drop-forged alloy steel construction ensure low field maintenance costs.

A: The YO18 and YO20 (18–20 kg) are lightweight and consume minimal air (≤20–33 L/s), making them ideal for small quarries and shallow bench holes (1.5–4m) powered by small portable compressors. The Y24 (24 kg) delivers higher impact energy (44.7J) for deeper holes up to 6 meters in hard bedrock.
A: Yes. While designed for manual downward vertical drilling, models such as Y19A, YO18, and Y24 can be attached to an FT100 support air leg to facilitate horizontal and inclined face drilling with reduced operator fatigue.
