Clamshells
Next to the backhoe bucket, the clamshell is one of the most important digging tools in the
utility business. The clamshell selection is based on the ground condition, the specific mate-
rial weight and the required production performance. The selection of the entire clamshell
attachment is significant in order to determine the required digging depth.
