ZT11 Integrated Open-pit Down-the-Hole (DTH) Drill Rig

introduction and Parameter:

Here is the English translation of the new paragraph:

It can drill vertical, inclined, and horizontal holes, and is mainly used for drilling blast holes and pre-split holes in large open-pit mines and rock engineering. It uses a Yuchai off-road diesel engine as the single power source, with the rear flywheel of the diesel engine driving the screw compressor system and the PTO port driving the hydraulic transmission system. The drill rig is equipped with an automatic rod handling system, a drill rod floating slide module, a drill rod lubrication module, an anti-jamming system, a hydraulic dry dust collection system, and a cab with air conditioning for both cooling and heating, as well as optional drilling angle and depth indication functions. The drill rig features good structural integrity, a high degree of automation, excellent drilling performance, environmental protection and energy efficiency, convenient operation, high mobility, and safe travel.
