Kalshang KQ311 Underground Tunneling Scaling Drilling Rig Machine
KQ311 full-hydraulic hair-prizing drilling rig is powered by Guosan diesel engine, which is mainly suitable for hair-prizing operation in metal mines and various underground tunnels. The working arm of the rig is foldable and equipped with a hydraulic hammer driven by a rotary oil cylinder and a mechanical translation mechanism, which can operate the working face, roof, side wall and floor in all directions. At the same time, the hydraulic system of the rig adopts proportional pilot control, so it has the characteristics of flexible operation and smooth movement. Compact structure, good mobility, small turning radius and strong climbing ability, which can greatly improve the efficiency and safety of crowning operation.
