1. A movement system for moving a block of stone material, comprising:
at least two movement devices, which are positioned spaced from and parallel to each other, for supporting a portion of a base of the same block of stone material and configured for moving said portion of the base of the same block of stone material, the at least two movement devices comprising:
at least one frame shared between said at least two movement devices, said at least one frame shaped for supporting a portion of the base of the same block of stone material, said at least one frame having a substantially planar supporting surface,
wherein each movement device comprises:
means for moving the same block of stone material, at least partially fixed to said at least one frame and configured for being positioned between said at least one frame and the same block of stone material, said movement means comprising at least one translation unit configured for moving a portion of the base of the same block of stone material in a translation plane, and a lifting unit configured for supporting and moving said portion of the base of the same block of stone material in a direction substantially perpendicular to said translation plane; and
actuator means configured for actuating said movement means in such a way as to allow an independent actuation of each of said at least one translation unit and of said lifting unit,
wherein each of said at least one translation unit comprises a rail fixed to said at least one frame and a slide slidably mounted on said rail, said slide being coupled to an actuator and said slide comprising a supporting surface for the same block, substantially coplanar with said translation plane.
