About the clamshell bucket
A hydraulic grab bucket with two closing shells for digging and transferring suitable loose material. Compare capacity, opening dimensions, attachment weight and the hydraulic supply for the intended excavator.
Features & benefits
Hydraulic opening and closure
Hydraulic actuation controls material pickup and release.
Enclosed material space
The shell form contains suitable loose material during movement within the rated capacity and lifting limits.
Typical applications
- Loose material loadingGrab and transfer sand, gravel and other suitable loose material.
- Restricted excavationWork in accessible narrow excavation areas with the appropriate carrier arrangement.
- Bulk material handlingLoad and unload suitable bulk material within the carrier lifting limit.

Product questions
Clamshell bucket questions
What material can a clamshell bucket handle?
It is intended for suitable loose material contained between two closing shells. Compare material density, moisture and particle size with the selected shell design.
Is a clamshell bucket the same as an orange-peel grapple?
No. A clamshell uses two shells to contain loose material; an orange-peel grapple uses several tines to grip irregular loads.
Does every clamshell bucket rotate?
No. Rotation depends on the selected configuration. Check whether powered rotation is included and confirm its hydraulic requirements separately.
How should capacity be selected?
Compare shell volume and attachment weight with material density and the excavator’s lifting chart at the working radius.
