EXPLO Series
The Explo-Wheel EWT 635 RC / CoreMultipurpose RC / Coring Drilling Rig |
The Explo-Trac ET 635 RC / CoreMultipurpose RC / Core Drill Rig |
The Reverse Circulation Drilling Rig is using a dual tube rod system, which allows for a cost effective retrieval of the cuttings from the face of the borehead to the surface by transporting them through the inner tube, thus eliminating the need for sample retrieval by tripping out or by the use of a wire line core barrel system. Although, RC drilling samples provide slightly less information regarding the formation, this shortage is largely offset by significantly reduced cost of drilling and rapid penetration rates.
Drilling Supply’s Explo series multipurpose drilling rigs feature models ET635 and EWT635, which were specially designed for mineral exploration using Reverse Circulation (RC) drilling and reflects our philosophy of designing our equipment with the end user in mind.
Drillers all over the world will be able to benefit from the Explo series rig's unique features optimized for high performance, efficiency and reliability in any operational environment.
These versatile and high performance drilling rigs feature Dual (2) speed hollow spindle rotary drive which greatly improves efficiency in both Reverse Circulation (RC) and Diamond Core drilling techniques.
The self-propelled ET635 exploration drill rig features a flat track (steel or rubber) Caterpillar system, while the self-propelled EWT635 drilling rig features an multidirectional AWD Hydrostatic 4 wheel drive system, provoding great maneuverability in restricted areas. The EWT635’s AWD 4 wheel drive axles are extremely powerful, and can easily overcome crimps and climb slopes up to 35% with the same stability as the track chain.
The EXPLO series drilling platform configuration is also available. This lightweight drilling platform configuration is offered ready to be U-bolted to any vehicle chassis, including 6, 8 or 12 wheels trucks, tractors, outlanders, or can be custom fitted to specific truck chassis, as specified by the customer.
The drilling rig's specifications can be adapted to fit your particular needs upon request. For example, a customer can customize the mast structure in order to accommodate drill pipes of any size (3 m (10'), 4.5 m (15') or 6 m (20') etc).
