KAISHAN KG420S and KG420SH are upgraded dual-power open-pit DTH drilling rigs optimized for complex mining and quarry working conditions. The optional diesel and electric dual drive modes support flexible power switching based on on-site power supply, which effectively reduces fuel consumption and construction costs while ensuring stable and continuous drilling performance. Equipped with dual rotary motors and upgraded hydraulic components, the rig outputs higher torque and stronger rock breaking capacity, perfectly adapting to hard rock stratum and high-intensity mining operations. The reinforced folded track frame and heavy-duty piston walking motor greatly improve climbing performance and terrain adaptability, ensuring stable traveling and drilling on mountain slopes, rugged ground and narrow construction sites. The upgraded enlarged pitching cylinder and lifting cylinder enhance operational stability and bearing capacity, supporting multi-angle limit drilling to meet diverse construction requirements. The whole machine adopts thickened steel structure and reinforced protective shell, effectively resisting vibration and external impact, prolonging service life and reducing equipment failure rate. The KG420SH model is equipped with an upgraded large-capacity dust removal system, which efficiently absorbs drilling dust and meets global environmental protection and green mining standards. With a drilling diameter of 90mm to 152mm and a maximum drilling depth of 25 meters, the rig covers most open-pit applications including quarry blasting, open pit mining, road slope trimming and infrastructure foundation drilling. With humanized operation design, simple structure and convenient daily maintenance, KAISHAN KG420S/KG420SH is a cost-effective dual-power drilling solution for global medium and large mining and engineering contractors.
