The NPK® X-Y-Z concept is designed to meet growing demand for renovation and refurbishing. X-Y-Z stands for relatively small attachments for all indoor removing, cutting and crushing activities. It provides improved safety in working conditions and makes hand labour redundant.

The X-Type Concrete crusher is standard equipped with the NPK® unique powerbooster and is remarkably silent. It has cast iron jaws, a rebar cutter and 360° free rotation.

The Y-Type Vibration scraper produces high vibration forces to a scrape plate, making it possible to remove carpets and other floor coverings, in forward and backward operation.

The Z-Type Pinch cutter tears down infrastructure, piping, electric wire or ceiling systems. It has cast iron jaws which cut away light metal structures.
