Reverse Circulation Drill Rig ET642

Reverse Circulation Drill Rig ET642
High performance Reverse Circulation (RC) exploration drill rigs models ET642-RC and EWT642-RC.
The self-propelled ET642 exploration drill rig features a flat track (steel or rubber) Caterpillar system, while the self-propelled EWT642 RC 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.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 exploration RC 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)
