ATLAS COPCO POWERROC T45 DRILL 

The PowerROC T45 surface drill has a telescoping boom and drills holes from 3 to 5 inches in diameter. It has an RD 22S hydraulic drill and 370-cfm air compressor. Power Eco allows the operator to select engine speeds—2,000; 2,100; or 2,200 rpm.

A 20-foot lead rod plus a three-rod, carousel-style rod-handling system provides on-board depth capacity to 54 feet with single-pass capability of 18 feet. A hydraulic smooth drilling system controls the rock drill power level, feed force, and rotation torque in response to changing rock conditions.
