<p>An apparatus for removal by suction, particularly of soil, of the type that comprises, supported by the chassis (11) of a means of transport (12), a partial vacuum unit (25) for a collection tank (14), to which the aspirated material is conveyed by associated suction means; the tank (14) is fitted on unloading means which are suitable to lift on one side the tank (14) in order to empty it by gravity of the material accumulated therein. The unloading means comprise a frame (16) which is rotatably coupled to the chassis (11) by interposing a center bearing (17), which rotates about a vertical axis and is provided with means for actuating the rotation of the frame (16) with respect to the chassis (11); the frame (16) has a base (18) for connection to the center bearing (17), and a supporting structure (19) for the tank (14) is associated with the base (18); the structure (19) has multiple movement means for positioning the tank (14) and unloading it outside of the footprint of the means of transport (12).</p> |
