These clamshells are designed identically to mechanical clamshells, the only difference is the closing and opening of the two buckets are by a hydraulic system.

As per your request, we can fabricate the hydraulic clamshell with a 360-degree rotating or either non-rotating type.

In the hydraulic system, two Hydraulic cylinders are used for this operation to force the bucket to close and open effectively scooping the material in the bucket.
