摘要

Retractable device for lid of the reservoir of large machinery and equipment agru00eccolas in general.Consist of basic and primarily, of a metal frame (1), which is fixed around the entire peripheral extension of the inlet (2) of the reservoir (R), and whose lateral segment are installed guide rails (3), during which slides the element of support (4). L One (5) of coverage, and the canvas cover is fixed by its rear end.A tube (10) provided in parallel to the rear segment of the metal frame, mounted on supports (11), fixed to the central shaft internal (12), which is liable to spin relative to its support lugs (13), fixed to the upper surface of the reservoir, and one end of the axis. The internal central circumscribed by spring (14), which is limited on one side by the said tube holder, and.On the other hand, stop (15) fixed on said shaft and said tarp cover flap fitting (16), provided in its central part front end which, when in position to cover the inlet reservoir, will be engaged in the retention tab (17) arranged in the central part Al of the segment front of said metal frame.While the lower stretch of the buoyancy provides continuous coverage of the tarp still shape curved in relation to the inlet of the reservoir.
