"The Heavy Range EC breakers generate powerful breaking power inside a streamlined body," said Kevin Loomis, construction tool business line manager. "Their simplicity also makes them a perfect addition to rental and equipment fleets because they're easy to maintain and handle."
The EC breaker attachments feature Atlas Copco's box-style mounting systems, which eliminate the need for removing external fasteners to access components, such as wear bushings and seals. This translates to expedited turnaround times for maintenance and, as a result, higher utilization rates.
The heavy-duty attachments are as light as 4,000 pounds and generate impact rates as high as 800 bpm to deliver effective impact energy to the breaking surface. With their high power-to-weight ratios, they're highly effective in demanding applications such as demolition, earthwork, quarrying and trenching.
Atlas Copco measures the power of its breakers using the Association of Equipment Manufacturers' foot-pound rating. The rating, which was developed by the Mounted Breaker Manufacturers Bureau, makes it easy for rental centers and contractors to compare breaker models by reviewing true figures collected after a certified test procedure.
The Heavy Range EC breakers also ensure smooth operation and long service lives with integrated features such as nitrogen-gas assist and Atlas Copco's exclusive Energy Recovery system. The nitrogen piston accumulator works with the hydraulic oil to accelerate the piston, which decreases the hydraulic oil demand from the carrier's hydraulic systems and delivers consistently high-impact energy. The Energy Recovery system minimizes hydraulic pressure spikes and captures reflected energy within the hydraulic accumulator to increase the impact performance of the next blow.
Finally, the breakers feature Atlas Copco's VibroSilenced Plus systems. They isolate percussion mechanisms from breaker boxes with polyurethane damping and seal all attachment openings to minimize noise and vibrations.
