Lifting unit

The lifting unit is recommended for the lifting of heavy submarine loads to the surface during refloating operations.

A standard range is available for load capacities from 100 kg to 8 tonnes. The RDF is manufactured from a high-strength PVC-coated fabric, and is equipped with inflation accessories and a quick-action overpressure relief valve, which is essential during the lifting of loads.

Pronal can also design and produce specific models which are tailored to your requirements.

RDFs are used for the flotation of loads in an underwater environment, the flotation of systems in the pool of a nuclear power plant, and for the raising and lowering of underwater loads.
