The Flexifloat Construction System by Robishaw Engineering is a combination of portable, interlocking modular barges and ancillary attachments, designed for use in inland marine, heavy-construction applications. All components of the sectional barge system are portable and made for efficient road transport by conventional tractor/trailers. Flexifloats can be quickly connected into larger assemblies of various sizes and shapes by construction crews without the need for specialized tooling or equipment. The resulting platforms are capable of supporting heavy equipment loads in areas that are practically or economically inaccessible to conventional deck barges.
