FlexiROC T30 R radio remote-control tophammer surface drill rig comes with either a COP 1240 or 1640 drill for 2- to 3.5-inch holes. The standard hydraulic carousel-type rod handling system uses 12-foot rods. The carousel carries four rods for a maximum drilling depth of 57 feet. A Cummins QSB4.5 turbocharged engine meets Tier 4-Interim requirements. The drill has extended boom coverage of 14 feet through an 80-degree radius. Radio remote control comes standard, allowing the operator full control of drilling, tramming and boom controls from a safe working distance on confined sites or unstable terrain.
