Abstract: A snow-plough blade group for absorbing lateral impacts comprising: a first and a second snow-removing blade; a first support bearing the blades; the second blade being mobile with respect to the first support between a first position, in which the blades identify a first snow-removing surface, and a second position in which the blades identify a second snow-removing surface larger than the first one; a second support hinged to the first support; a first hydraulic cylinder connected between the first and second support for orientating the first support with respect to the second support; a discharge of liquid in overpressure; bypass valve means connecting the first hydraulic cylinder with the discharge, which bypass valve means are configured such that when the pressure in the first hydraulic cylinder exceeds a threshold value, the bypass valve means place the first hydraulic cylinder in liquid communication with the discharge; characterized in that a sensor detects a position assumed by the second blade; and

Abstract: An extensible snowplough blade comprises a fixed blade body (10), having a substantially linear conformation in a longitudinal direction and is provided, at a posterior surface (11) thereof, with means for support (12). It further comprises a raising structure (20) for defining a hinged connection between the blade body (10) and a vehicle (150). The raising structure (20) in turn comprises a frame (21) for fixing thereof to the vehicle (150) and coupling means (25) of the fixed frame (21) to the means for support (12). The extensible snowplough blade (100) further comprises a first extension (30), slidably mounted on the means for support (12) in a parallel position to the blade body (10) and destined to extend longitudinally with respect to the blade body (10) in a left-wards direction, and a second extension (40), slidably mounted on the means for support (12) in a parallel position to the blade body (10) and destined to extend longitudinally, with respect to the blade body (10), in a right-wards direction.

Abstract: A snowplough blade with adjustable width, of the type including: a first, stationary blade body (L1), supported by a frame (S) for suspension and coupling to a respective machine (O); and a second blade body (L2), connected to the first blade body (L1) by mutual coupling means, sliding and moving with respect to the latter, operated by actuating means (A) between a retracted position (R) and an extreme advanced position (EA), in which the snow-removing surface of the snowplough blade (L) is maximum. The second blade body (L2) is situated in front of the first blade body (L1). The first blade body (L1) includes a tubular cross-beam (1), connected to the suspension and coupling frame (S) and housing the actuating means (A).
