Kaishan ZT11 Integrated Surface DTH Drilling Rig — Premium High-Pressure Driller

Power management in the ZT11 is highly advanced. The Yuchai YCA08320-T300 engine uses its rear flywheel to drive the air compressor directly, while the front PTO (Power Take-Off) drives the hydraulic pumps. This configuration ensures that power is distributed exactly where it’s needed, resulting in a more responsive machine. With a built-in compressor delivering 18m³/min at 22 bar, the ZT11 has the “punch” required to drill 90-130mm holes to an economical depth of 32 meters, even in the toughest rock (f=6-20).

The ZT11 is packed with intelligent features designed to protect the equipment and the operator. The “floating joint” module protects the drill rod threads from excessive wear, while the automatic electro-hydraulic anti-jamming system monitors drilling parameters in real-time to prevent the bit from sticking. These systems, combined with the 7+1 automatic rod handling system, make the ZT11 one of the most productive rigs in its weight class.

Operator safety and comfort are paramount. The ZT11 features a luxury cab that is both ROPS (Roll-Over Protective Structure) and FOPS (Falling Object Protective Structure) certified. Inside, the operator enjoys a climate-controlled environment with standard AC, heating, and radio, all while noise levels are kept below 85dB(A). The use of hydraulic pilot controls ensures precise, effortless operation, reducing operator fatigue during long shifts.

With a massive 120KN of traction and 355mm of ground clearance, the ZT11 is incredibly mobile for a 15,000kg machine. It can navigate steep grades and rough terrain with ease, moving between holes without the need for auxiliary equipment. For mine owners who demand high reliability, advanced safety standards, and a low cost-per-meter, the Kaishan ZT11 is the ultimate integrated drilling solution.
