JCB Attachments' range of crusher buckets — the CB60, CB70, and CB90 — are designed to work with the JCB line of tracked excavators, from the JS160 to the JS360. Powered by the standard hydraulic breaker circuit, the crusher buckets use a fixed jaw in the base, with a hydraulically activated hinged jaw in the roof of the bucket. The buckets are designed to reduce site waste, brick, demolition rubble or rock into usable material. They are particularly useful in demolition applications, providing an onsite recycling resource. The buckets have 30-hour greasing intervals with only two lubrication points.
