ABSTRACT:
A carrier for lifting and transporting a heavy ladle including a tractor and a trailer having a longitudinal center line and a U-shaped frame and a rearwardly opening cradle pivotally mounted on the frame for embracing the ladle and with hooks suspended from the cradle for engaging and lifting the ladle by its trunnions provided with a hydraulic lift cylinder for vertically pivoting the cradle with respect to the trailer frame and wherein the cradle legs have extension members hinged thereto and are interconnected by a hydraulic swing actuator for selectively swinging the legs and extension members about the hinges so as to shift the cradle and hooks laterally with respect to the trailer center line. In the preferred embodiment the cradle and the hydraulic lift cylinder are pivotally connected to the trailer frame with ball connections to permit limited lateral tilting thereof and the cradle is essentially self-centering with respect to the trailer center line when the pressure in the hydraulic swing actuator is relieved.
