Silent Operation for Urban Projects

The fully enclosed box-type housing provides 50%+ noise reduction compared to open-type breakers of the same class. This meets strict municipal noise regulations, allowing operation in residential areas, near hospitals, schools, and other noise-sensitive environments. Ideal for urban redevelopment, indoor demolition, road repair in city centers, and foundation work in confined spaces.

Compact Yet Powerful

Despite its small size, the SB30 delivers efficient breaking performance for concrete slabs, asphalt removal, light rock breaking, and trenching in hard soil. The box type enclosure also protects internal components from dust and debris, extending service life in harsh working environments. Nitrogen gas-charged system enhances impact efficiency.
