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.
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:
- Exchangeable grip add-ons
- Skeleton version available

Typical jobs
The Mini-Excavator Clamp Bucket is used for:
- Pipe and pole handling
- Loading, unloading and sorting rocks, pipes and debris
- General excavation with the clamp holding the load
- Urban construction projects with space constraints
- Landscaping work where material is set down in place
- Debris removal and sorting in compact areas
- Light demolition tasks and clearing brush
- Utility installations in residential areas
- Work in confined spaces
- Jobs where the machine digs and also handles material
The Clamp Bucket lets your mini-excavator dig, then grip and sort what it has loosened. Contact us and we will help you find the right fit for your machine.
Which coupler is on your machine?
Pick the system on your machine and we put it in your enquiry. We check the bracket before we send the quote.
How to measure your coupler
Not sure which system it is? Three measurements tell us which bracket you need.
- Measure the diameter of both pins.
- Measure the distance between the pin centres.
- Measure the width between the inside faces of the ears.
If the coupler has a make or type printed on it, send that too.
