Atlas Copco adds new Boltec EC to bolting rig fleet
The newest addition to Atlas Copco’s fleet of rock bolting and reinforcement rigs is the Boltec EC, a fully mechanized rig that features the new BUT 45 heavy duty boom. The Boltec EC is also equipped with a new rock drill, the COP 1435, which delivers up to a 30 percent higher penetration rate than its predecessor, the COP 1132.
The Boltec EC installs rock bolts from 4.9 feet to 19.7 feet in length, and is designed for a hole range of 1.4 to 2.5 inches. The rig is built on a sturdy, articulated carrier with four-wheel drive.
“The Boltec EC is fast, accurate and stable, and designed for bolting in large mining and tunneling applications,” explained Ed Tanner, Atlas Copco business line manager. “We are also offering several levels of optional automation that save time and improve productivity, including features such as Bolt Angle Indication and Bolt Plan Navigation.”
“The new heavy-duty BUT 45 boom is an important addition as well,” said Tanner. “It’s very steady and allows for direct, fast and accurate positioning between holes.” The BHR 20 feed rotary unit has a double rotation unit for plus or minus 190-degree feed roll-over and plus or minus 135-degree feed rotation.
In the field, the first Boltec EC rigs have already achieved an installation rate of 120 to 130 bolts per shift, and have been used to drill holes for power lines and water pipes.
