Underwater Digging Buckets Application: Hawco electro-hydraulic underwater digging buckets are intended for use on automated floating dredges commonly used in the sand and gravel industry. These buckets offer a superior option to those being supplied out of Europe due to Hawco's heavier duty design and roundnose bowl design. The roundnose bowl design offers greater digging capabilities and therefore, consistent full loads even in harder digging materials. Sizes: 6 to 16 cubic yards Specifications: Reversing motor, submerged pump hydraulic system Commonly used, readily available hydraulic components All alloy steel construction. Pins and bushings made of heat treated 4140 and 4150 alloy stock. All pins and bushings are lubricated through recessed grease fittings. Lip material is T-1 alloy Weld-on replaceable manganese alloy tooth points and adapters Offset bowl design prevents upper housing from catching on trench walls.
