CB-mini hydraulic clamp digging bucket
- 1.2–10 tons

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 gives your mini-excavator more jobs to do
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, so you can carry a load and set it down where you want it.
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 machine you already run.
