Sub Frame: The drill rig's seperate mono-constructed frame is integrated with the trailer chassis. The rig is supported by 4 hydraulic operated jacks, with double check valve. Overall width of frame: 2.550m Overall height incl. trailer app. 3.950m overall length in transport app. 5.200m
Guide Mast: Max. pull down with rotary head 140kN. Max. hold back with rotary head 260kN.Rotary head: The rotary head has two hydraulic motors working in parallel hydraulic connection. The rotary is mounted with KNEBEL BREAK-O-MATIC system, and hydraulic chuck for quick replacement of drill tools.Hydraulic System: The hydraulic circuit works with the following maximum flow / pressure at 1800 engine RPM 330 litre / min and 280 bar from the pump.Rig & Compressor Diesel Engine: Make of engine is Deutz, type BF 8 M 1015C, water cooled V-build, 4 stroke diesel with direct injection.Mud Pump: Gardner Denver 5 x 6High Pressure Air Compressors: The drill is equipped with one rotary screw air compressor dual stage compression. Make of compressor: ATLAS COPCO Type of Compressor: XRV9-229-PTOEC. The capacity on above compressor is max. 25 bar pressure and 455 litre per second +/- 4% or (950 CFM/350psi) free air delivery. The compressor is driven from the diesel engine flywheel end, through flexible drive using max. 295kW at 1,800 engine RPM.Drill Pipe Storage Facility: The rig has storage facilities for 55 unit 6m 4 3/4" drill pipe, weight app. 8,250 kg place in containers at left side of the loading rail. This allows for a 330 metre depth to be reached without reloading.Low Bed Semi-Trailer for Above Rig: To carry the above drill equipment on narrow roads and difficult terrain the Rig is mounted on a low bed semi-trailer with steering of the four rear wheels.This trailer has capacities to load max. 31 ton in CVW divided with 11 ton on tractor and 20 ton on two axles. The axels at the trailer are with automatic hydraulic control for steering, and it will follow the tractors track around corners.
For driving on close space the rear wheels has remote seperate steering with connection for the cable at either front or rear end of trailer. The wheels suspension are with hydraulic load and wheel control to give maximum stability and load control to each wheel. |
