Crusher Buckets
Crusher buckets lower transport costs by crushing and screening material on site. They boost efficiency in recycling, mining and excavation work.
HKM crusher buckets turn your excavator into a powerful mobile crushing plant. Suited to 10-50 t carriers, the CB10, CB20, CB30 and CB40 offer heavy-duty steel construction, high-efficiency hydraulic drive and quick-change jaw plates for minimal downtime and continuous productivity.
Simple mounting and easy operation reduce haulage costs and eliminate waiting for fill material. From recycling demolition waste to crushing quarry stone, they let you crush and screen directly on site.

This tool performs a pre-selection based on catalogue values and is not a binding quotation. Attachments without a hydraulic supply, such as rippers, have no flow or pressure rows; those models are unaffected by the flow filter. The final choice is made together, based on material, workload and the hydraulic equipment of the carrier.
