ApplicationThe GL-3000,Website:http://www.rejeedrilling.com, is mainly applied for core drilling of geological exploration in tunnel(gallery). This tunnel exploration drilling machine can also be used for exploration and reinforcement constructions(including core drilling and standard penetration) of foundation works, such as road, railway, bridge, dam foundation and industrial & civil projects, etc. Features1.High efficient and low power consumption since the power changes with load with direct-acting hydraulic system of load 2.feedback turning variables;3.Quick and precise in hole defining and positioning with accurate vertical rig,power head rotation and speedup display device;4.Convenient and fast in traveling with crawler walking function;5.Easy regulation, wide speed range with high efficient fully hydraulic power head transmission and infinitely variable speed;Compact, ideal for tunnel(gallery) drilling.Technical DataMax torque2900N.mwith the high-speed power head5000N.mRotation speed of top-drive head0-500r/minwith the high-speed power head0-610r/minStroke of top-drive head1800mmRated pull force of top-drive head94kNRated thrust force of top-drive head 48kNRod dia ɸ 50mm; ɸ73mm;ɸ89mmDrilling angle rangeleft and right ±3° ;front and back 0-90° Power unit 45kWOverall dimensionsworking:3390*1600*3150(mm)Moving:3110*1600*1800(mm)Total weight 3600kgSystem pressure 26MPaCylinder extension1000mmMaximum grade-ability 20°Moving speed1.5km/h
