Lid closure device for a tanker, in particular sewerage tanker, which can be filled with liquid

摘要

A lid closure device for a tanker (1), in particular sewerage tanker, which can be filled with liquid has on the top of the tanker (1) an opening (3) and a closure lid (7), which can be swivelled about a swivel axis (9) which runs transversely to the direction of travel. In order to permit automatic closure of the closure lid when starting up after filling has taken place, there is provision for a float element (17) which acts on the closure lid (7) attached inside the tank (1) in such a way that the lifting forces exerted on the closure lid (7) via the float element (17) when the tank (1) is filled produce a torque which acts counter to the direction of rotation of closure of the closure lid (7) and that a stop (23, lever 31b) for limiting the maximum swivel range of the closure lid (7) is arranged away from the opening (3) (Figure 1).
