WellDrill - Model 3060 CR -Well Drilling Rig
Atlas copco Welldrill`s WellDrill 3060CR well drilling rig is designed for all down-the-hole (DTH) drilling applications. 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 work in restricted areas. Ten degrees of chain feeder tilt – forward, backward and sideways – make 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 rotator assembly is an Atlas Copco DHR 48H56, driven by two hydraulic motors, with drill bit sub coupling for 2 3/8” API Reg box thread. A control valve allows the hydraulic motors to be operated in series or in parallel. An ODEX 115/140 casing shoe is mounted on the sled and is equipped with hydraulic advance.
The entire drilling rig has been designed to give service technicians easy access to all components. All hoses are neatly and logically arranged on hose ladders and marked to give a clear overview of the hydraulic system. The direct-acting hydraulic system has radio control of movement functions. The drilling control panel is 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, as well as welding and water pump controls. The side panel also has duplicate controls for moving the machine.
