MULTI-PURPOSE DRILLING RIGS (RC/CORE)

ET642-RC/c and EWT642-RC/c Multi-Purpose Exploration Drill Rigs

High performance multipurpose (Reverse Circulation / Diamond Core) exploration drill rigs models ET642-RC/c and EWT642-RC/c.

Multipurpose (Reverse Circulation / Diamond Core) exploration drill rigs models ET642-RCc and EWT642-RCc

The main advantages of ET/EWT series drilling rigs are its extreme maneuverability; pullback capacity of 48000 lbs (21 770 kg); hydraulic power of 160 HP; rotary drives with variable/reversible hydraulic motor and automatic constant rotation power control; and a unique pipe handling system. These features enable ET/EWT series rigs to easily access almost any type of difficult terrain, and give it enough power to drill in any type of mixed hard formations. The drilling angle is 0-100 degree from horizontal, which is suitable according to your drilling requirements.

The self-propelled ET642 exploration drill rig features a flat track (steel or rubber) Caterpillar system, while the self-propelled EWT642 drilling rig features a multidirectional AWD Hydrostatic 4 wheel drive system, providing great maneuverability in restricted areas. The EWT642’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.

Our equipment has been having good reputation for its simplicity, efficiency, maneuverability, productivity and in particular on fuel consumption.
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.

If choosing both the RC and the Core drilling packages, there’s no significant time loss when switching from one drilling technique to another:

  1. Down-The-Hole to Reverse Circulation and vice versa –switches immediately, thanks to the 3 way valve;
  2. DTH/RC to Auger/Rotary and vice versa – about 10 min;
  3. DTH/RC/Auger/Rotary to Coring and vice versa – about 2 hours.

Other interesting feature is the possibility to install and adapt a Coring head very quick and easy due to the fact that the hydraulic system is conceived consequently.

Please note that below specifications can be adapted to your needs on request, for example, the must structure designed and can be build for drill pipe of 3 m (10’), 4.5 m (15’) or 6 m (20’).
ET/EWT series drill rigs are designed with the end user in mind. You will be able to benefit from its unique features optimized for high performance, efficiency and reliability in any operational environment.

Working temperatures: All our standard equipments are meant to operate CONSTANTLY at any temperature varying between - 45 to + 50 degrees Celsius (-49 F to 122F).
