Atlas Copco released the FlexiROC T45 tophammer surface drill rig, which it says uses half as much fuel as its predecessor, the ROC F9, using the same rock drill.

“Field testing has proven and our customers confirm that the FlexiROC T45 uses half as much fuel as its ROC F9 predecessor, using the same rock drill in similar rock conditions,” said Maurice Hunter, business line manager for the company’s Surface & Exploration Drilling Equipment area. “Additionally, the new rock drill COP 3060 mounted on a fixed boom with aluminum feed produces larger diameter holes using the T60 drill string with outstanding performance, reliability and mind-blowing fuel economy.”

The company says it designed the new rig to minimize energy loss and boost productivity. Operators can adjust airflow and dust collector fan speed to match working conditions, and the engine and compressor automatically fall in line. The FlexiROC T45 has half the hoses and 70 percent fewer couplings than comparable rigs on the market. Hydraulics and electrical components are also laid out to facilitate service and maintenance. Its hydraulic tank is 60 percent smaller than previous models, making use of biological hydraulic oils more economical. The engine meets the strict Tier-4 environmental standards—though a Tier-3 engine is also available.

“It's an incredible accomplishment to increase productivity and drilling capacity while reducing fuel consumption so dramatically,” said Mario Santillan, product manager for Atlas Copco Surface Drilling. “Everybody wins when there's less environmental impact, a better working environment, and higher profitability.”

The FlexiROC T45 is designed for a variety of applications, including construction and quarrying.
