1. A method of preventing the overloading of the weight capacity of an opaque truck body when said truck body is used for hauling several different materials of different density, wherein loading material of a first density to the full volume capacity of an initially empty truck body does not exceed the weight capacity of said truck body;

  • said method comprising the steps of;

    a. loading material of a second greater density into an initially empty truck body;

    b. sensing the horizontal distribution of the material of a second density at discrete locations along a predetermined level on said truck body side wall which corresponds to less than the full volume capacity of said truck body and which defines a maximum loading level for said material of a second density beyond which level the weight capacity of the truck body would be exceeded; and

    c. stopping the loading of the material of a second density into said truck body in response to the sensing of an even horizontal distribution of the material at the predetermined level.
