Tools for the construction industry

These screening buckets have been specially designed for the quick and effective screening of material. The HSB series screening buckets are ideal for sorting natural materials. This enables the material to be recovered for the desired processing and managed as effectively as possible. The HSB series covers a range of applications: primary sorting of waste and demolition material, screening of backfill material for excavations and material for the rehabilitation of stony areas, sorting of pebbles in watercourses, and beach cleaning. Simply indispensable in areas where fine material needs to be recovered or where materials need to be sorted into different sizes. Manufactured from sustainable steel grades with extremely low wear rates. This guarantees minimal maintenance and a long service life.Advantages of the HSB series screening buckets: Screening directly on site. Lower transport and landfill costs (less sand in the rubble). Useful, simple and quick to operate. Suitable for both large and small construction sites. Helps you recycle and save money. The size of the screen can be easily adjusted by changing the screen mats. These screening buckets are connected to the excavator’s hydraulic hammer function.
