The CB mini is a hydraulic clamp bucket for mini-excavators. The bucket digs and the clamp holds, so one tool loads soil and then picks up a root, a kerbstone, a pipe or demolition waste.
About this family
The Clamp Bucket digs and grips material on a mini-excavator
The Clamp Bucket is a hydraulic bucket for mini-excavators. It digs and can also grab and sort material and take on light demolition work.
The clamp runs off the machine’s auxiliary circuit. A double pilot check valve holds the load if hydraulic pressure drops.
The body is S355JR2 steel and the cutting edge is HB500. The grip add-ons are exchangeable, and a skeleton version is available for separating soil from stone.
It fits tiltrotators and the usual mini-excavator couplers, so it turns and tilts with the tiltrotator.
Features
- Digging bucket and clamp in one: load soil, then pick up what a bucket cannot hold
- S355JR2 steel on body
- HB500 cutting edge
- Tiltrotator Compatible
- Double pilot check valve for work-holding: the load stays held if the pressure drops
Optional features:
