Underground core drill rig Explorac235

Explorac reverse circulation drilling rigs were developed in cooperation with exploration professionals. Every component has been carefully designed to provide excellent drilling results and to meet demands from contractors, miners and geologists – while ensuring operator safety and minimum environmental impact. 

The Explorac 235 rig meets all the challenges of exploration with reverse circulation. While designed specifically for reverse circulation drilling to depths of 300-400 meters, the rig can easily be adapted for other down-the-hole drilling.

All the power you need for medium-depth drilling

The Explorac 235 meets all the challenges of exploration with reverse circulation. While designed specifically for reverse circulation drilling to depths of 300–400 meters, the rig

can easily be adapted for other down-the-hole drilling. The Explorac 235 is available for assembly on a truck or crawler chassis.

Rod handling

The standard rod handling system provides safe transport of the rods back and forth from a rack, supply truck or off the ground to the drill center Other safety features include radiocontrolled

tramming and a safety cage preventing operators from being close to rotating items.

 

Breakout

A fully hydraulic slips table with top and lower spanners,guides, clamps, and holds any tool with a 305-mm opening.

A hydraulic wrench performs all breakout functions safely of any tool.

Power pack

The fully enclosed power pack and cooling fans reduce the noise level. Air power is supplied by the latest XRY12 compressor, providing a pressure of max 35 bars (510 psi). The

air system is prepared for external booster connection up to 70 bars.

Control panel

The user-friendly control panel can be positioned up to 10meters from the rig providing safety and visibility. The display shows all information parameters and warnings for the

power pack, compressor and hydraulic system.

Cyclone

It features an integrated cyclone and sample collection system, allowing continuous, sampling with little or no pause in the drilling process. A three-tier splitter is fitted as standard

under the cyclone for efficient sample collection. Other splitter options are also available.
