Equipment Focus: Drilling & Blasting

The Atlas Copco FlexiROC T45 top hammer surface drill rig gives users a flexible, efficient tool that is uncompromising in regard to fuel efficiency. According to Atlas Copco, field studies showed that the FlexiROC T45 with fixed boom uses half as much fuel as similar rigs using the same drill. Maurice Hunter, Atlas Copco business line manager of surface and exploration drilling equipment, says the FlexiROC T45 uses half as much fuel as its ROC F9 predecessor under similar conditions. In addition, the COP 3060 rock drill mounted on a fixed boom and aluminum feed manages large diameters using the T60 drill string for better performance and reliability. During operation, FlexiROC T45 operators can adjust the airflow and the dust collector fan speed according to actual work demands. The engine speed and compressor are then adjusted automatically. The FlexiROC T45 features a superior cabin environment. Atlas Copco adds the cost of ownership and operation on the drill rig is significantly lower than competitive drill rigs because the FlexiROC T45 has 50 percent fewer hoses and 70 percent fewer couplings than similar rigs of its class. The company positioned the drill rig’s hydraulics and electrical components close to their functions, which makes them easier to service and maintain. This feature also reduces the risk of a leakage. The FlexiROC T45’s hydraulic tank is about 60 percent smaller than what is featured on previous drill rig models, making it economical to use biological hydraulic oil without increasing total costs. As a result, no environmental cleanup is necessary if an accident occurs. The drill rig’s engine meets Tier 4 environmental standards. Sulfuric oxide has been reduced by 50 percent and particle emissions by 90 percent. Additionally, the drill rig can come with a Tier 3 engine, if desired.
