Epiroc Launches New EC 122 Hydraulic Breaker

Epiroc has launched the new EC 122 hydraulic breaker, with improved handling, extended service life, and simplified maintenance. The new model follows the introduction of the EC 102 breaker at Bauma 2025.

The new EC 122 hydraulic breaker comes with a set of changes aimed at making maintenance faster and reducing wear-related downtime. One of the main updates is in the lower wear bush, which now uses a turnable wear insert. By rotating the insert during service, operators can spread wear across multiple surfaces instead of concentrating it in one area. The insert can be replaced in the field without special tools, a move intended to shorten service stops.

The company has also added a replaceable piston liner, designed to simplify repairs and avoid more extensive component replacement when wear accumulates.

Weight reduction targets mid-size carriers

The revised EC 122 is around 80 kg lighter than the previous model. Service weight is listed at 1,120 kg, and the breaker is intended for carriers in the 15 to 24-ton class. In this segment, attachment weight can affect machine balance, transport, and maneuverability, especially on confined jobsites.

Hybrid system and vibration measures

On the technical side, the EC 122 combines hybrid technology with a nitrogen piston accumulator. The configuration is intended to support more consistent impact output and smoother operation across varying hydraulic conditions.

Epiroc’s VibroSilenced Plus system remains part of the package, with the percussion mechanism isolated and openings sealed to limit noise and vibration transmission, which can be a factor in operator comfort and compliance on urban or restricted sites.

Hydraulic efficiency and internal wear control

The breaker includes an integrated control valve and Epiroc’s EnergyRecovery system to improve hydraulic efficiency and reduce vibration. Active percussion chamber ventilation is used to lower internal wear, supporting longer operating periods between service interventions.
