  • Patent number: 4878551
    Abstract: An improved ladle transfer car for transporting ladles and providing accurate and consistent weight measurements for the ladle and its contents. In a preferred embodiment the ladle transfer car comprises a car body supported upon multiple truck assemblies. Connecting each of the truck assemblies to the car body is a shear beam load cell pin. Associated with each of the truck assemblies is a stabilizer assembly. The stabilizer assemblies permit the vertical movement of the car body relative to the truck assemblies and they help to prevent the horizontal movement of the car body relative to the truck assemblies. Each of the stabilizer assemblies includes a pivot arm which extends substantially perpendicular to the major axis of the truck assemblies. The pivot arm is pivotally connected at one end of the car body and pivotally connected at the other end to a respective truck assembly. Mounted in the immediate proximity of each of the shear beam load cell pins is a keeper assembly.
