Product Description
Underground mining machinery hydraulic fanhole drill
GP71 Hydraulic drilling jumbo is the first choice for no sill pillar and high sublevel caving technology in metal mine. The jumbo can meet the specific
drilling requirement with versatile positioning function. Reliable sliding stable and rotary boom positioning system ensure the jumbo high accurate
driling. Equipped with high power hydraulic drifter, and adopted advanced electrohydraulic control technology with hight mechanized operation
make the jumbo is of high productivity. The jumbo can drill parallel and fanshaped deep holes in big section tunnel at a time once stabilization.
So improves blast output per unit.
