ABSTRACT:
A floatable apparatus provided with a lifting element for displacing it between the surface and bottom of a water basin has at least two jaws or grippers which are suitable for use as a clam-shell bucket or the like. The jaws are suspended from the lifting element and are articulated with respect to one another. The lifting element is constituted by a principal floatable buoyant caisson which permits the apparatus to be placed in a state of immersion or of floatation. At least one floatation chamber is associated with each of the jaws to achieve selectably a net density thereof equal to, less than or greater than that of water. The jaws are carried by the principal caisson.
