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.

Claims

1. A portable transfer ladle for use with a forklift truck having spaced apart tines and a power supply source thereon comprising:

a support structure having a pair of spaced apart tine-receiving holes therein and including a pair of spaced apart ladle support members located above said holes and bearing means on said pair of ladle support members for rotatably supporting a cylindrical ladle;

a cylindrical ladle rotatably mounted on said spaced apart ladle support members of said support structure and rotatable about the longitudinal axis of said cylindrical ladle which is located above and between said spaced apart tine-receiving holes, said cylindrical ladle having a spout on one side and a counter-weight located on the periphery thereof in a position substantially opposite to said spout, said support members mounting said bearing means along the longitudinal axis of said ladle;

and a ladle drive assembly mounted on said support structure and connected to rotate said cylindrical ladle, said ladle drive assembly including a motor detachably connectable for energization and control from said power supply source.

2. A portable transfer ladle according to claim 1 wherein said support structure comprises a pair of hollow elongated spaced apart members each having one of said tine-receiving holes therein and on which said pair of ladle support members are mounted.

3. A portable transfer ladle according to claim 2 wherein said tine-receiving holes extend parallel to said axis.

4. A portable transfer ladle according to claim 1 wherein said ladle drive assembly further includes a reduction gear unit driven by said motor, a drive sprocket on said reduction gear unit, and a cylinder drive chain engaged with said sprocket and having its ends connected to said cylindrical ladle.

5. A portable transfer ladle according to claim 4 wherein said ladle drive assembly includes a power input receptacle.

6. A portable transfer ladle for molten metal for use with a forklift truck having spaced apart tines and a power supply source thereon comprising:

a support structure comprising a pair of hollow enlongated spaced apart members each having a tine-receiving hole therein, said support structure further including a pair of spaced apart ladle support members, each ladle support member being rigidly connected to said hollow elongated members;

a cylindrical ladle rotatably mounted on said support structure, said cylindrical ladle being rotatable about an axis which is located above and between said spaced apart members, said cylindrical ladle having a spout on one side and a counterweight located on the periphery thereof in a position substantially opposite to said spout, means on the inner surface of said ladle that defines a chamber for receiving molten metal;

bearing means on said pair of ladle support members for rotatably supporting said cylindrical ladle;

and a ladle drive assembly mounted on said support structure and connected to rotate said cylindrical ladle, said ladle drive assembly including a motor detachably connectable for energization and control from said power supply source.

7. A portable transfer ladle according to claim 6 wherein the tine-receiving holes in said hollow elongated spaced apart members extend parallel to said axis.

8. A portable transfer ladle according to claim 6 wherein said ladle drive assembly further includes a reduction gear unit driven by said motor, a drive sprocket on said reduction gear unit, and a cylindrical drive chain engaged with said sprocket and having its ends connected to said cylindrical ladle.

9. A portable transfer ladle according to claim 8 wherein said motor is an electric motor and wherein a power input receptacle is mounted on said support structure.
