Two 200-hp G45 Rockwheels installed on CAT349 excavators have helped the contactor complete a challenging rock excavation project in New York state.  Geo technical data indicated rock to be in the 14,000 psi range.  Because they were excavating next to an operating treatment plant, hammers and explosives were too risky because of possible collateral damage.  In addition the rock excavation went right up to newly set caisson walls and concrete support pillars.  The G45 rockwheels were favored because of low disturbance to surrounding structures and becasue of their ability to cut continuously.  In additon to the two G45 Rockwheels a smaller AX20 and D10 were used where even more precision was required.  Excavator mounted rock cutting tools from Alpine Rockwheel are available world wide.  www.alpinecutters.com
