This surface down-the-hole drill rig features both a diesel engine and an electric motor, which allows operators to work in different modes. Owing to a piston motor and reinforced continuous track, the drilling machine works better in ramp climbing. Moreover, the wide swing and tilt angles make the unit suitable for various drilling applications. Characterized by two rotational motors that can boost feed and pull out force and reliable operation of the machine, this rotary blasthole drilling rig is made of reinforced materials strong enough for it to be moved from site to site. This heavy land drilling machine is also equipped with a dry dust collector which can effectively reduce pollutants to the air.
