An apparatus for the removal and replacement of a lid on a metallurgical transport vessel such as a ladle or a torpedo car. The apparatus comprises a frame, means for supporting the frame such that the vessel may be moved into position thereunder, a linkage including at least one lifting member pivotally connected to the frame, and at least one actuator connected to the linkage. The actuator is operable to move the lifting member such that when the vessel is moved to a designated position below the apparatus, the lifting member can be moved by the actuator and linkage from a first position providing clearance above the vessel, through a curved path to an intermediate position where it engages the lid, providing a vertical lifting force and a horizontal hinge releasing force to the lid, and to a second position where the lid is raised to a sufficient height to clear the vessel. The lifting member may subsequently be moved back by means of the actuator and linkage through a reverse curved path to the first position, and thereby lower the lid back on to the vessel.
An apparatus for the removal and replacement of a lid on a metallurgical transport vessel, comprising:
In a metallurgical facility using a vessel with a lid having a disengageable hinged connection to the vessel, the lid being removable from the vessel by moving the lid upwardly and horizontally relative to the vessel, and using a car on rails for transferring the vessel, an apparatus for removing the lid from the vessel, comprising:
A method for removing a lid from a metallurgical transport vessel, the lid having a rearwardly releasable hinged connection to the vessel, comprising the steps of:
