KAISHAN KT7D integrated open-pit DTH drill rig is an upgraded automatic integrated drilling equipment optimized for medium and hard rock open-pit mining and quarry blasting projects. Integrating a high-pressure screw air compression system and professional down-the-hole drilling system, the whole machine cancels auxiliary external air supply equipment, realizing independent walking, fast positioning and one-stop automatic drilling construction.
Powered by a reliable 175KW Yuchai off-road diesel engine, matched with 18bar high working pressure and large air displacement, the KT7D provides strong and stable impact force. It effectively improves penetration efficiency for hard rock formations, perfectly adapting to high-intensity blasting drilling operations in medium and large quarries and open-pit mines.
Equipped with a standard automatic rod handling system and professional drill rod lubrication module, the equipment realizes semi-automatic drilling operation, greatly reducing manual intervention, lowering labor costs and construction risks. The upgraded high-strength aluminum alloy feeding beam features strong shock resistance and structural stability, avoiding deformation during long-term cyclic high-load drilling.
The heavy-duty crawler chassis supports 25° climbing capacity, with outstanding trafficability on rugged mountain slopes and complex construction sites. The built-in high-efficiency dust collection system effectively suppresses construction dust emissions, complying with international environmental protection specifications. Supporting vertical, inclined and horizontal multi-angle drilling, KAISHAN KT7D is a stable, energy-saving and cost-effective automatic integrated drilling solution for global mining contractors and rock engineering
