Nitrogen Charged Technology

The advanced nitrogen gas-charged accumulator system stores and releases energy during each impact cycle, amplifying the striking force while reducing peak hydraulic demand. This results in more efficient breaking with lower fuel consumption and reduced hydraulic system stress, extending the service life of both the breaker and carrier excavator.

Extended Service Life Design

Main body cylinder forged from high-grade alloy steel with full heat treatment. Replaceable front head bushings protect the main cylinder body. Auto lube system available for continuous greasing. All internal components manufactured to tight tolerances for consistent long-term performance with minimal maintenance requirements.
