Underground mining wheel mounted drill
SBR-6 Robust MacLean Engineering

Taking the capability for breaking oversize rocks in the ore production cycle one step further. Integrating the patented Ro-Bust%u2122 hydro fracturing system and MacLean's PLC-controlled operating system, the Ro-Bust%u2122 Blockholer provides the tools to safely and effectively break rocks without high explosives.

- The MacLean Advantage:

* Oversize is fragmented at source, without damage to draw point infrastructure
* Greatly reduces fly rock and virtually eliminates blast-induced dust and noxious gases
* Significantly increases productivity of a stoping area by reducing ore flow interruptions
* Particularly effective in reducing LHD maintenance costs by eliminating overloading when carrying large boulders
* Increases stope value in NPV terms by allowing faster extraction of developed resources (blasted or caved ore)
* More effective than mechanical/hydraulic rock breaking, particularly boulders larger 2m in volume

- Features:

* Fully self-contained drilling system; no air or water services necessary
* Radio and optional video system designed for underground environment
* Hydraulic rock drilling
* Patented Ro-Bust%u2122 rock breaking technology
* Heavy duty frame construction
* High-powered, electronically controlled Caterpillar%u2122 engine option
* Reliable, proven power train components
* Four wheel drive carrier
