The Rock Drill Rigs are designed for geothermal and water well drilling. It is mounted on a versatile crawler track platform with high ground clearance and 360-degree rotation, which makes this unit exceptionally well suited for working in restricted spaces. The 360 degree ro-tation gives the driller an exceptional reach without reposition the drilling rig. The WellDrill has a direct hydraulic control system with all functions accessible via external control panel mounted on a hydraulic swinging arm, with duplicate controls for positioning. A side panel provides controls for the drilling machine chain feeder, pipe rack, stinger advance and other cylinder movements. The side panel also has duplicate controls for moving the machine.
Ten degrees of chain feeder tilt – forward, backward and sideways – makes the unit very useful on undulating ground. It is supplied as standard with wide, heavy-duty rubber tracks that minimize soil disturbance. The chain feeder has a stinger mounting that permits vertical movement of the feeder. The rotation unit is driven by two hydraulic motors and a control valve allows the hydraulic motors to be operated in series or in parallel, optimizing either torque or rotation speed.
The entire drilling rig has been designed to give service technicians easy access to all com-ponents. All hoses are neatly and logically arranged on hose ladders and marked to give a clear overview of the hydraulic system.
