ABSTRACT:
An improved tilting lug assembly for a metallurgical ladle includes an elongated hooking link having one end portion pivotally mounted on the sidewall of the ladle by a rigid support bracket positioned substantially 90.degree. circumferentially from the ladle trunion axis, with an open eye on the other end of the hooking link. The hooking link is normally biased to a substantially horizontal position with the open eye projecting outwardly from the ladle sidewall in position to be easily engaged by the lifting hook of a crane for tilting the ladle, with the link being freely pivotable in an upward direction on application on an upwardly directed force and being pivoted downward from the normal horizontal position against the biasing means upon application of a downward force whereby engagement of the hooking link with an obstruction during raising or lowering the crane will not result in inadvertent tilting of the ladle.
