Product Description
 Application and feature
GP71 Mining jumbo suits for various underground non-coal mines, of which cross section is 3.5mX3.5m-4.5mX4.5m, and is the first choice for no sill pillar and high-sublevel caving. It can meet the specific drilling requirement of versatile positioning with reliable sliding table and rotary boom positioning system, high accuracy drilling, high-power HC109PR drifter, mechanized and high performance, and advanced electric hydraulic controlling technology. Stopping in front of a large cross section at a time, it can greatly improve blasting output per unit by drilling parallel and medium-length blast holes. 
1Hydraulic components feature of superior performance, high reliable and good versatility. Main hydraulic parts (hydraulic oil pump, multiple directional valves and control spools) are imported with original packaging.
2Hydraulic system has perfect protection device: auto stopping after finishing drilling; anti-jamming mechanism, low oil alarm and other protection devices. 
3Hydraulic drifter is imported from MONTABERT France, of which hydraulic system is energy-saving, high effective and reliable. 
4Equipped with water system and air system, and could blow holes.
5The machine is modular designed, which makes convenient space for assembling and maintenance
