FINE23X

Special Feature

Silenced Box type breaker is advanced Design with ANTI BLANK firing feature (AUTO STOP).

The percussion chamber is inserted in outer box body, with Polyurethane dampers in between, for more effective shock absorption.

This enhances not only the life of breaker components, but also increases the life of Base excavator super structure, swing components and Boom & stick.
