13 Drill tools are manually connected to the rotary head from the back of the rig. A partnership for progress 1.04 HYDRAULIC PIPE KEYS and BREAK-OUT-CYLINDER: The lower end of the guide mast is equipped with a dual hydraulically operated pipe key for retaining rods, or other in hole tools. The keys consist of two sliding keys which close by a built-in hydraulic cylinder. When opened, the keys can be pulled away and open up for large diameter casing. To reduce the key sizes, inserts can be installed. Max. static load for the clamp is stated in technical data for stable mast on ground. A hydraulic break-out cylinder is also installed at the bottom of the mast ENGINE + HYRAULIC SYSTEM: The hydraulic system is powered from the liquid cooled diesel engine, with capacity to run the hydraulic pump. The engine is directly coupled to the hydraulic pump. Complete instrumentation at panel including a main electrical switch. Dry element combustion air element with safety cartridge. The hydraulic system is powered with oil pressure and flow from a variable displacement piston pump. PRINTED IN POLAND Boart Longyear is constantly striving to improve its products and must therefore reserve the right to change designs, materials, specifications and price without notice.

14 To secure a long trouble free run, the system is protected with high pressure filter at pump delivery line and return oil filter at tank line. All pressure filters have indicator for clogged up element. The hydraulic system is connected to oil cooler enabling the exchange of heat with the fresh air by means of thermostat control. The hydraulic flow is distributed from a central mounted proportional load sensing manoeuvre valve. The control of the valves is normally remote with electrical cable connection. The tank is equipped with air breather filter, thermometer, oil level gauge, and drain plug. A hand-pump is installed to push the hydraulic oil into return filter of the tank in order to ensure that new oil is filtered when refilling. The oil tank is pressurised. Hydraulic hoses conforms to CE. A partnership for progress 1.06 MAIN WINCH ON MAST TOP: The rig is equipped with a hydraulically powered winch, with automatic hydraulically opened brake. The rig is delivered with non rotating wire, completed with thimble, clamps and safety hook.

15 1.07 RIG FLAT PLATFORM: A partnership for progress The rig steel body is constructed as a box steel frame. In the body are mounted main valves and other equipment. Over the crawler left side is installed a frame to contain drill pipes. The frame can hydraulically be tipped over to the back of the rig and then hydraulically dumped. So all drill pipes / rods are in position near to rotary head. A small toolbox is placed on the main boom NIGHT LIGHT: The rig is completed with a light system, covering the drilling place, instrumentation and the rig CONTROL PANEL: The control panel is electrical and is to be placed on the ground during drilling. The panel has the remote control with instruments, gauges and switches to control the drilling and erection. The control panel is fully closed when not in use. To drive with the rig is installed a electrical control box located on the platform in the rear of the frame UNDERCARRIAGE: The above drill rig is mounted on a type undercarriage with rubber tracks. PRINTED IN POLAND Boart Longyear is constantly striving to improve its products and must therefore reserve the right to change designs, materials, specifications and price without notice.

16 Type of undercarriage - oscillating type. As standard it is equipped with a tow hitch for compressor and hydrostatic tension of belts. A partnership for progress 1.11 AIR CIRCUIT: At the back of the rig is mounted a connection for the air-hose for a compressor. The piping on the rig brings the air from the back of the rig to the drillhead. The rig is prepared with a remote controlled valve for opening and closing for air to the drill string. A lubrication pump is installed to inject oil into the airline. The lubrication flow is adjustable. The rig is painted in Boart Longyear white RAL ADDITIONAL EQUIPMENT 2.01 FLUID PUMP: A hydraulically driven fluid pump is installed below deck in the body of rig, the pump has capacity to supply water or foam to the air line. The pump installation is complete with safety valve, outlet with delivery hose to the airline.

17 2.02 WELDING GENERATOR: A partnership for progress A hydraulically driven welding generator is installed below deck in the body of rig, the welding generator has capacity to weld standard casing. The generator installation is complete. Welding cable and handle from generator to welding site is included GRINDING MACHINE: An electrically driven drill bit grinder is installed at the back of the rig. Because of its compact design, its ability to handle both threaded and DTH bits, this grinder is the most versatile grinder available. Some of the new features include *True Profile Centring Technology which grinds the gauge button to its near axial centre, and a powered tilt-able bit table with adjustable pre-set angle, for reduced set-up time. A new digital control panel now controls the grinding process from start to finish, and allows the operator to easily control grinding time, feed pressure, and view system information. The grinder installation is complete but must be connected to external voltage power supply source. The grinder cannot be installed if also a dust collector is installed.

18 2.04 ADDITIONAL ROD RACK: A partnership for progress Over the crawler right side is installed a frame to contain additional drill pipes or water-tank. The frame can hydraulically be tipped over to the back of the rig and then hydraulically dumped. So all drill pipes / rods are in position near to rotary head DUST COLLECTOR: The dust collector is hydraulically driven and covers the normal size of drilled holes. The collector is specially designed for the DTH rig to reduce dust in and around the working area, thus providing a clear, safer environment. The hydraulic dust collector is delivered with a new and more effective silenced fan-house. The dust collector is placed on the back of the rig and the installation is complete with mounting and hose to dust deflector house on mast. Water in the dust collector will cause damage to the filters. The dust collector cannot be installed if also a grinder is installed SLOPE WINCH: On the back of the rig is mounted a hydraulic slope winch to assist driving the rig in difficult terrain.
