Atlas Copco has boosted its breaker range with the addition of three new models. These breakers form part of the essential case-mounted (EC) range and are designed to fit 22- 49tonne carriers. The heavy range breakers are the EC 140 T, EC 150 T and EC 155 T. As with other models in this range, the new units are said to offer fast return on investment due to factors such as simplifed maintenance and operation.

The firm claims that these EC breakers generate powerful forces inside a compact body while being simple and durable, suiting them to use in rental and equipment fleets.
The EC breakers feature Atlas Copco’s box-style mounting design, which eliminates the need for removing external fasteners to access components, such as wear bushings and seals. This reduces service times and helps boost utilisation.
The heavy-duty attachments deliver impact rates as high as 800bpm and provide high breaking power to the working area. High power-to-weight ratios are said to ensure high productivity in a range of demolition, earthwork, quarrying and trenching duties.
The new EC breakers are also said to offer smooth operation and long service lives, with features such as nitrogen-gas assist and Atlas Copco’s novel 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 high-impact energy. The energy recovery system is said to minimise hydraulic pressure spikes and return reflected energy within the hydraulic accumulator to increase impact performance for the next blow.
The breakers also feature Atlas Copco’s VibroSilenced Plus technology to reduce working noise. This is said to isolate the percussion mechanism from the breaker box using polyurethane damping and seals at attachment openings.
