CMJ17HT hydraulischen Bohr-Jumbo

drilling Jumbo,hydraulic crawler drilling jumbo CMJ17HT hydraulicdrilling Jumbo CMJ17HT hydraulic drilling Jumbo is mainly used to drill blastholes for tunneling construction in mines of metallurgical, nonferrous metal, coal etc, and also hydro-power station, railroad, highway engineering, etc. The jumbo is designed with two drilling booms, advanced hydraulic rock drill system and 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, and it also can drill anchor holes upward. With modular designed, this small compact jumbo has a low center of gravity, great mobility, remarkable stability and strong climb capability thus can improve working environment and get efficiency, quality development.
