Electro-Hydraulic Clamshell Buckets
Hawco electro-hydraulic clams can be designed to handle the complete range of bulk commodities typically handled by stevedores. Advantages of the electro-hydraulic clam are that it can be easily hooked up to a single hook type crane and because it is hydraulic, it can be designed with enough closing force to handle any bulk commodity effectively.
