SCOPE OF APPLICATION
* Tunneling
* Highway Tunneling
* Reservoir Rrigation Tunnel
* Pumped Storage Power Station
* Underground Cavern
MAIN FEATURES
* STRONG ADAPTABLITY OF SECTION: Pioneering curved arm bracket structure, with large operating range, can meet the upper, middle and lower bench operation of two-bench cut method and three-bench cut method;
* STRONG ADAPTABLITY OF WORKING METHOD: With curved arm structure, the arm could work below the level, which can achieve inverted arch excavation;
* HIGH EFFICIENCY AND ENERGY SAVING: The efficiency of single hole is 5-6 times that of manual pneumatic drill.
