The Best Onshore and Offshore Drill Rig or Mineral Exploration Rigs GPS15 Hydraulic Drill Rig Equipped with Gravel Pump Sets for Deep Hole Drilling

R.C.D Machine is large bored pile equipment of soil foundation. Our model GPS-15 drilling rig is applied on large diameter cast-in-situ piling with reinforced-concrete for high-rise building, harbor, dam, bridge, and can also drill large diameter hole of water well and engineering hole.The main models include GPS10,GPS15,GPS18 and GPS20, etc.

Main features

1,The rotary table is equipped with six speeds, remarkably improving construction efficiency.

2,Rotary table drives drilling pipe through shifting rod, much more convenient for operation, higher safety and greatly reducing labor intensity.

3,Both main and auxiliary hoists adopt planetary gear structure, easy for operation and more reliable.

4, Adopt round drill pipe, reducing the auxiliary operation time.

5, Equipped with gravel pump set (pump-suction reverse circulation), can transfer to reverse circulation drilling if needed, and can also matched with air-lift reverse circulation drilling tools for deep hole drilling.
