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
Combines the heavy DTH rock drilling system and an onboard two-stage screw compressor (18 m³/min @ 22 bar / 319 psi) onto a single crawler chassis. Powered by a single 235 kW Yuchai YCA08320 diesel engine driving both compressor and hydraulics via flywheel and PTO outputs, it eliminates trailing air hoses and cuts jobsite fuel burn by up to 25%.
Features a heavy-duty articulated drill boom with a 148° beam tilt angle, 1,500 mm compensation stroke, and 37 kN maximum propelling force. The automated 7+1 rod carousel, floating slide module, and electro-hydraulic anti-jamming system allow safe, single-operator deep drilling down to 32 meters.
Equipped with an ergonomic, climate-controlled safety cabin meeting international ROPS & FOPS certifications with low interior noise below 85 dB(A). The 15,000 kg heavy-duty chassis features ±10° track oscillation and 355 mm ground clearance, ensuring stable tramming across 25° quarry slopes.

A: The ZT11 upgrades the onboard two-stage screw compressor discharge pressure to 22 bar (versus 17 bar on ZT10), expands diesel engine power to 235 kW (versus 228 kW), increases maximum propelling force to 37 kN (versus 32 kN), extends rotation speed up to 173 rpm, and enlarges the carriage tilt angle to 148° for superior penetration efficiency in ultra-hard rock formations.
A: No. The ZT11 is completely self-contained. The 235 kW Yuchai diesel engine powers the hydraulic drilling and tramming systems while directly driving the onboard 22-bar two-stage screw air compressor, operating autonomously with zero trailing hoses.
