The KG310/KG310H open-air DTH drill rig is new equipment upgraded in response to the country’s environmental protection requirements. Equipped with Yuchai’s two-cylinder National III engine to meet the country’s requirements for emissions and environmental protection. The flexible luffing mechanism can meet the function of drilling low-level horizontal holes.
At the same time, the hydraulic system is upgraded to increase its system flow and increase the rotation speed. Optimize the lifting cylinder to improve its reliability, strengthen the guide rail and increase the upper and lower wear plates of the sliding plate to extend the service life. Add hoisting rings (plates) to facilitate loading, unloading, and hoisting.
The KG310H type adds a dust collector and adopts double dust-catching cylinders, which are more environmentally friendly and reliable when working.
