Marine Rotary Hoe

A new tool to our product range soon to undergo sub sea evaluation, designed specifically for dredging in difficult soils that may be hard or very 'sticky' where water jetting has up till now been the only option.

The principle here is to mechanically break up the soil composition and fluidize it in the same motion so it can be sucked away through the mouth of the tool. This tool retrofits to the suction inlet hose of our existing 3, 4 and 6 inch dredges with simple cam locks and adapter as shown.
