Excavator Silent Hydraulic Breaker
The enclosed-housing silent hydraulic breaker is a flagship attachment designed for urban environmental compliance. The entire machine adopts a one-piece sealed HARDOX wear-resistant steel plate enclosure. Its reinforced, wear-resistant casing and heat-treated piston design ensure a long service life, even in dusty and harsh operating conditions.
Specifically engineered for noise-reduction operations in urban areas, the product line covers the full range of excavators—from 0.8-ton mini-excavators to 50-ton large-scale mining models—and is the preferred choice worldwide for municipal demolition, urban renewal, and residential construction projects.
Quiet Demolition, Unstoppable Force.
