A structure (40) to protect a cabin (2) of a vehicle (1), in case of fall of heavy bodies onto the cabin (2) and/or in case of tilting of the vehicle (1), without points of contact with the cabin (2). It comprises a lower connection portion (11) for connecting the frame (3) of the vehicle (1), preferably by means of a connection plate or connection flange (14) and of a counterframe (4) to be reversibly mounted to the frame (3), an upright (12) that in use extends vertically from the connection portion behind the cabin (2), preferably at an angle with respect to the cabin (2), and a cover means (13) for covering the cabin (2), said cover means extending from the upright (12) to form a plane shield above the cabin (2). The cover means (13) may comprise a continuous shield (17), or a plurality of linear elements, preferably stiffened by a frame. According to an aspect of the invention, the cover means (13) is movable with respect to the lower connection portion (11), between a use position, at which it is arranged above the cabin (2), and a maintenance position, at which it does not hinder the forward rotation of the cabin (2) and/or the access of an operator between the cabin (2) and the upright (12). In an exemplary embodiment, the cover means is rotatably arranged with respect to the lower connection portion about a rotation axis integral to an upright that is fixed with respect to the lower connection portion, said axis being horizontal or even vertical, in which case one or two lateral shields is/are provided. In other exemplary embodiments, the cover means is fixed with respect to the upright, and the rotation axis is integral to the connection portion, or the cover means is slidably arranged in a guide element made on an upright or made on the lower connection portion. |
