The Amfirol was build to make tranches in a big lagoon for land reclamation.
To dewater the lagoon which consisted of dredged clay trenches needed to be made. The dredge clay could not support any other type of vehicle than the Amfirol. The two Archimedes screws providing buoyancy and traction in all kinds of soil. The twin screw Amfirol can be equipment with disc wheels and a ditch cutter to make dewatering channels in the mud. The mean advantage of the Amfirol is that it can move trough mud and similar types of soil and the Amfirol can adjust its traction depending on the soil type.
