Rotomite - Model 4000 -Self-Propelled Diesel Dredges
The Rotomite 4000 has the same pump, engine, and hydraulics as the SD-110, but it`s built with steel pontoons, and has a maximum dredge depth of 15`. The Rotomite 4000 is a good solution when the strength of steel is required due to frequent moves, but the production of the SD-110 is sufficient.

Crisafulli`s hydraulically powered propulsion and steering system for the Rotomites is unique in the dredge world. Providing both thrust and steering, the System provides adequate force to enable the horizontal auger on the cutterhead to engage, cut, and dislodge compacted solids.
Unlike propulsion systems on many competitors` dredges, that either crawl along the lagoon bottom thereby generating substantial turbidity, or drive one or more "spuds" into the lagoon bottom that must be removed and the dredge relocated repeatedly by a support vessel during the dredging process, the Crisafulli propulsion system generates little or no turbidity and enables the Rotomite to be self-sufficient and move easily around the lagoon, canal, or river without external support. The System provides both forward and reverse thrust. Rotomite propulsion systems are more flexible and versatile enabling Rotomites to be more productive and less costly to operate.
