Couvering structure of the driving place of operative machines

摘要: The invention realises a covering structure (1) of the driving place (2) of operative machines (3) for road - works comprising canopy (4) which insists on frame said operative machine by supporting elements (5) and shifting means (6) suitable lifting it. Each is formed at least couple traces (7, 9) made movable one of said shifting is arranged between them and realises their compass movement in order to lift canopy. When is lifted, are an angular position according an angle (20) amplitude wider than 180°, favouring its filling when lowered.
