What is a crusher bucket and how does it work on an excavator or loader?

Expert Answer

A crusher bucket is a hydraulic attachment that mounts to an excavator, skid steer, or backhoe loader and crushes demolition waste or natural stone on site. It uses the carrier’s auxiliary hydraulic flow to drive internal crushing components that reduce material to reusable aggregate. In practical terms, you load concrete, brick, asphalt, or rock into the bucket, the material is compressed and broken down, and the crushed output exits at a controlled size range. This helps reduce hauling, tipping fees, and the need to bring in processed fill from elsewhere. Performance depends on the machine’s weight class, hydraulic flow, pressure, and the material being fed. VANROCK manufactures and supplies crusher buckets for these machine types and can help match the right size and hydraulic requirements to your carrier before quoting.
