  • Publication number: 20210299911
    Abstract: Described is a system and a method for moving a block of stone material, wherein the system comprises at least two devices comprising: a translation unit onfigured for translating a base of the block in a translation plane and a lifting unit configured for moving a base of the block in a direction substantially vertical to the translation plane; actuator means configured for allowing an independent actuation of the translation unit and of the lifting unit, the overall configuration of the movement device being such as to allow a progressive translation on the translation plane of the block of stone material with respect to a reference plane.
