Hydraulic Breaker Optimization for Carriers in the 15–24-Ton Range
Epiroc introduces the EC 122 hydraulic breaker to improve maintenance cycles and reduce carrier load through a modular bushing system and hybrid technology. www.epiroc.com The EC 122 hydraulic breaker is a medium-duty attachment designed for demolition, rock excavation, and quarrying, optimized for carrier vehicles weighing between 15 and 24 tons. This model update follows the release of the EC 102 at Bauma 2025 in Munich, focusing on reducing the digital supply chain friction of replacement parts by extending component longevity. Modular Engineering and Maintenance Efficiency Maintenance requirements for the EC 122 are addressed through a redesigned lower wear bush that incorporates a turnable insert. This mechanism allows operators to rotate the component to redistribute frictional wear across its surface area, which extends the service life of the bushing without requiring specialized tools for field adjustments. To further enhance repairability, the unit features a replaceable piston liner. This design choice allows for the restoration of the percussion mechanism without replacing the entire cylinder block, targeting a reduction in long-term total cost of ownership. Internal wear is further mitigated by an active percussion chamber ventilation system, which prevents the ingress of dust and debris during the piston's stroke. Weight Reduction and Hydraulic Performance The EC 122 features a service weight of 1,120 kg, representing a mass reduction of 80 kg compared to its predecessor. This reduction decreases the stress on the carrier’s boom and hydraulic system, which improves maneuverability and fuel efficiency during sustained operations. The breaker utilizes hybrid technology, combining a nitrogen piston accumulator with hydraulic pressure to maintain consistent impact energy. This is paired with an EnergyRecovery system that captures the recoil energy of the piston to increase blow frequency without requiring additional hydraulic input from the carrier. Vibration Damping and Noise Suppression For environmental and operator safety compliance, the breaker integrates the VibroSilenced Plus system. This technical framework isolates the percussion mechanism from the external breaker box through damping elements and seals all frame openings. This configuration reduces both acoustic emissions and high-frequency vibrations transmitted to the carrier's arm. Control is managed via an integrated valve that regulates hydraulic flow to ensure the breaker operates within specified parameters regardless of fluctuations in the carrier's hydraulic output. This regulation helps prevent internal overheating and seal failure in high-duty cycle applications such as secondary breaking in quarries.
