<p>Device for supporting a platform that is used to lift loads or persons the height of a structure. Together with a platform, the inventive device includes winch-type platform-lifting elements and modular assemblable mast-forming elements. Each mast element is installed using the load platform which can be connected to the masts by: (i) the aforementioned winch-type lifting elements which can be disconnected at will from the masts, and (ii) elements for temporarily blocking the movement of the platform in relation to a modular element of each mast. In this way, when the movement of the platform is blocked, a modular element can be added to, or removed from the top of the masts in accordance with the desired platform lifting height. The platform is positioned between two modular independent masts which form a lifting and guiding path.</p> |
