Detailed Description
APPLICATIONS:    KDY-30H hydraulic drill rig is a multi-function drill rig developed facing drilling grouting  hole for hydro-power station. It also can be used for drilling the hole of support, penetration-proof, blasting; and treating dangerous rock and hillside. It is mainly suitable for drilling hard rock with diamond bit and PDC bit, and DTH drilling as well. MAIN FEATURES: Reasonable specification, assure more efficiently drilling; Fully hydraulic drive, top-drive head rotation, feed and hoist are all done by ration pump and ration motor which composite independent open hydraulic system, it is simple, advance, easy to use and maintain; The main hydraulic components are from world famous hydraulic manufacturers, two-step filtering, to assure the reliability of the hydraulic system; Newly-designed structure, three speeds, and can get different speeds through changing oil motor of top-drive head, to satisfy the needing of different drilling technology; Light weight, easy to move, re-assembly and maintain. Especially suitable for drilling in tunnel and on the frame. Technical Specifications SPECIFICATIONS: Drilling method: diamond drill bit, PDC bit, and DTH drilling Drilling capacity: 30 m(hole dia.: Φ75 mm); 20 m (hole dia.: Φ91 mm) Drill rod: Φ42 x 1000 mm or Φ50 x 1000 mm Top-drive head: stroke: 1200 mm; Max. push/pull force: 14 kN; feed and hoist speed: 0-0.3 m/s.
