ABSTRACT OF THE DISCLOSURE The invention provides a new support superstructure for tarpaulins employed to cover the open top of a load container of the permanently-installed, side-rolled type or of the type that is installed as and when required. The superstructure comprises a plurality of transverse support members, usually convex-bowed upwards that in an operative position extend fully across the container body, each being connected at one end to a vertical pivot rod mounted on one side of the body in vertically-spaced bearings. The support member is moved to an inoperative stored position alongside one wall by manipulation of a handle at the lower end of the pivot rod and accessible to an operator standing on the ground. The two support members at the respective ends of the body can be fixed. Each pivot rod may be movable vertically in its bearings to facilitate the movement of the support members over a heaped load. The handle also operates to latch the support member in the operative position, and also the inoperative position if required. The tarpaulin may have longitudinal transversely-spaced stiffening rods which rest on the support members when it is unrolled to reduce the number of support members required. The opposite side wall carries a ramp member for each support member that is engaged by its free end during its final movement into the operative position, in case the end sags too far downward; each ramp terminates in a stop member that locates the support member in the operative position.
