<p>The device for cleaning snow-covered road pavings comprises a tilting supporting device (13), suitable to be connected to a road tractor (5) and having a central snowplough blade (15). The snowplough blade (15) carries scraper blades (14) suitable to adapt to the road paving configuration. To the tilting supporting device (13) is connected at least a wheel (17), placed resting on the road paving and provided with sensor means (18) suited to detect the charge that weighs on the same wheel. The sensor means are connected to actuator means (10) suitable to drive the articulation means (9a, 9b) of the tilting supporting device (13), determining the transfer of part of the weighing charge from the wheel (17) to the rear axis of the road tractor (5), when such a charge goes over a predetermined threshold.</p> |
