The REMU Big Float amphibious dredgers are engineered for challenging excavation jobs at seashores, shallow lakes, marshlands and industrial ponds. The Big Float can be driven autonomously without the need for extra transportation or cranes because of the tracked pontoons. Moreover, with additional pontoons and anchoring legs, the Big Float can excavate 9 m deep in open water. The pontoon structure is divided into 8 baffle sections to ensure safe floating. Also, the pontoons can be hydraulically narrowed to 3 m for transportation and produce just 160g/cm3 of surface pressure towards the ground. The Big Float excavators are optimal for cleaning industrial ponds, reclamation of mine tailings, dredging, pile driving, environmental works, waterways preparation and canal cleaning.
