Module for making ambidromic crossover equipment (fam)

A module for making a modular ferry and/or a floating bridge comprising a floatation tank made in the form of two floatation half-tanks hinged together around a hinged line between an opening position in which the two half-tanks are substantially aligned and form the floatation tank, and a closing position in which a half-tank is folded back upon the other half-tank such as a lid thus forming a container box, wherein the module encloses all or part of the elements for making the ferry or floating bridge of which at least one treadway element movably mounted between a stowing position in a low part of the half-tank and along a direction that is substantially longitudinal to said half-tank, and a deployed position in which the treadway element comes substantially over the half-tank and is directed substantially along a direction transversal to the half-tank in the vicinity of a median line of the floatation tank.
