CMJ17S twin powered crawler drilling Jumbo is mainly used to drill blastholes for tunneling constructions in coal mine, metal mine, non-ferrous metal mine, hydro-power station, railroad, highway engineering etc. The jumbo is designed with two drilling booms, advanced hydraulic rock drill system, anti-jamming mechanism for making it has rapid drilling speed and high efficiency. Flexible mechanism can make the jumbo drilling on face, slope, roof, side wall and floor in underground mine or tunnels. With modular designed, this small compact jumbo has a low center of gravity, great mobility, remarkable stability and strong gradeability. Because of a diesel engine pewered for travelling, it has a good maneuverabililty and no need pulling a cable, thus can be improve working environment and get efficiency, quality development.
