ABSTRACT:
A cover assembly is provided which is adapted for use on a receptacle transporting vehicle having a receptacle supporting scull frame swingable from a receptacle transport position to a dumping position for discharging molten contents of the receptacle. Included in the assembly is an insulated lid member for opening and closing the receptacle, the closure position retarding heat loss from the molten contents to preclude solidification during transport thereof between spaced locations. A pair of laterally spaced-apart support arms, mounted so as to move concurrently with the swingable scull frame, position the lid member adjacent the top of the receptacle during scull frame movement and especially during transport of the receptacle from one location to another. A pivot assembly rotates the support arms for similar movement of the attached lid between receptacle opening and closure positions, such movement being independent of the scull frame movement. An operator-actuated piston system selectively controls lid movement between the opening and closure position. The assembly is mounted to the scull frame to provide rotation of the lid in a direction away from and contra the rotational movement of the scull frame from the transport to dumping positions to preclude interference of the lid with the contents being discharged from the receptacle.
