CB - heavy duty hydraulic clamp bucket
CB Hydraulic clamp / grab bucket
- 10–26 tons
- On request
- Carriers: Midi, Standard
The CB is a digging bucket with a hydraulic clamp arm on top. The bucket digs, the arm closes onto the load, and between them they pick up what a plain bucket drops: demolition rubble, stumps, pipes, awkward stone.
About this family
The CB Hydraulic Clamp Bucket. Grab, Sort & Transport with Ease. Double pilot check valve ensures work-holding & safety.
The CB hydraulic clamp bucket digs and can also grab, sort and carry material. It is used for laying pipes, moving tree trunks and handling large stones and debris.
A double pilot check valve holds the clamp shut if a hose fails, which is what keeps a held load from opening, and the bucket carries the CE mark. Three sizes: CBR-120 for 10 to 12 t machines at 1000 mm wide, 430 dm3 and 355 kg;
CBR-190 for 12 to 19 t at 1200 mm, 803 dm3 and 631 kg; CBR-260 for 19 to 26 t at 1200 mm, 1071 dm3 and 1100 kg.
Arms are built in several shapes, and the brackets run from S60, MS10, CW20, OQ60, M18 and SW33 on the smallest to S70, MS21, CW40, OQ70, M26, S2 and SW48 on the largest.
Feature highlights
- Hydraulic Clamp: Holds the material securely while it is grabbed and moved.
