Rotary Blasthole Drilling Rig, KG430S/KG430SH
Surface down-the-hole drill rig for open-pit mining
The rotary blasthole drilling rig is equipped with disel engine of less emission and it is also equipped with an electrical motor, which means that a worker can operate the drilling rig between two modes. This kind of drill rig features a piston motor and reinforced continuous track, both of which help the rotary blasthole drilling rig work better in ramp climbing. Additionally, 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, this construction tool is made of reinforced materials strong enough for its transportation from site to site. A dry dust collector is included in this drilling machine which effectively reduces pollutants to the air.
