The Cable Arm clamshell works on a two-cable system. One cable is attached to four spreader cables, which control the opening and closing of the bucket. The second cable draws the clams together and lifts. Creating a level-cut in the sediment, which is essential for precision dredging.

Unlike conventional clamshells, our Level-Cut® clamshells swing open under their own weight. This eliminates the need for counterweights, which:

- Lowers overall weight
- Increases payload
