The Paving breaker model B47 is a professional-grade tool powered by compressed air. It is specifically designed to pave and break concrete foundations, and is highly effective in engineering installations for breaking other hard materials.

The compressed air is distributed alternatively through the distributing valve into either end of the cylinder assembly. This creates a reciprocal motion for the internal hammer, which impacts the shank of the steel chisel. Driven by the tappet, the chisel penetrates concrete foundations and hard structures, splitting them into manageable pieces efficiently.
