New Rock Drilling Rig with patented Prime Double Rod System

Prime Drilling’s newly innovative Rock Drilling Rig with Prime Double Rod System and ‘on board’ pump is equipped with double pipes and available in capacities ranging from 400 to 1,500 kN pull force.

The new rock drilling rig is the first of its kind on the market featuring power levels >50 t. The inner and outer drill pipes are independently driven by two sliding rotary heads. The drill bit that powers the inner pipe is available with torque from 9,000 up to 45,000 Nm, depending on the type of rig. This combination creates drilling results in the most difficult geological conditions.
The outstanding feature for this rig is the ability to use any common locating system with double rod operation, even use of a wire-line system is possible.
