Variable-geometry rolling device which can be adapted for transporting all-terrain loads. It consists of the combination of a rolling member resembling, as closely as possible, a spherical 17, 18 or diamond shape and then in supporting it 22, 23 and finally in coupling it to a second element of the same diameter but which is independent. It is intended to equip lightweight trolleys and the like which move over non-supporting terrains or ones which are, sandy, submerged or the like, while reducing the towing force and avoiding tilting. <IMAGE>
