Abstract
Abstract A portable transfer ladle for receiving molten metal from a melting furnace and depositing it in holding furnaces or molds remote from the melting furnace is constructed so as to be transportable by and operable while on a conventional forklift truck. The portable transfer ladle includes a support structure having hollow elongated spaced apart members for engagement with the tines of the forklift truck, a cylindrical ladle rotatably mounted on the support structure, and a ladle drive assembly mounted on the support structure to rotate the ladle and including a motor detachably connectable for energization and control from a power source located on the forklift truck.
