Truck with built-in weighing mechanism and load hold-down device

Claim 2

In a truck of the type described, a truck chassis frame, a plurality of transversely and longitudinally spaced seat means arranged above the chassis frame and on which the truck body is supported, a scale, force transmitting means between all of said seat means and said scale whereby downward forces on said seat means incident to increased loading of the truck will be registered on the scale, and means for fixing said truck body against upward movement relative to said chassis frame with said last named means comprising a plurality of motors at each side of said chassis frame at longitudinally spaced points therealong and fixed thereto, each motor having an upwardly extending power operated element, a steam projecting upwardly from each such element, and means for transmitting force from the upper end of each stem to the truck body to prevent upward movement thereof relative to said chassis frame.

Claim 3

Apparatus according to claim 1 provided with a plurality of frame brackets fixed against the outer faces of the chassis frame at longitudinally spaced points therealong, each motor being fixed to one of said bracket, each bracket having a vertically elongated guide through which said stems project for transmitting lateral forces to the chassis frame.

Claim 4

Apparatus according to claim 1 wherein said last named means comprises a plurality of body brackets carried by said truck body and projecting laterally therefrom at longitudinally spaced points, and means for transmitting downward forces from said motors to said body brackets to fix said body against upward movement relative to said chassis frame.

Claim 5

Apparatus according to claim 3 provided with a plurality of frame brackets secured at spaced points along opposite sides of and to said chassis frame, each motor being secured to one of said frame brackets.

Claim 6

Apparatus according to claim 4 wherein each frame bracket is provided with vertically spaced rigid plates projecting outwardly from said chassis frame, and a sleeve fixed to each pair of said plates and through which one of said stems is vertically slidable.

Claim 7

In a truck of the type described, a truck chassis frame, a plurality of transversely and longitudinally spaced seat means carried by said chassis frame, a truck body resting on said sheet means, scale means carried by said truck body and including a scale beam mounted to pivot on a hOrizontal axis, force transmitting means connected between all of said seat means and said scale beam whereby the weight of said truck body and the contents thereof will exert a force on said seat means and move said scale beam, and force applying means for preventing upward movement of the truck body relative to said chassis frame, said last named means comprises a plurality of motors at each side of said chassis frame, each motor being adjacent one of said seat means and fixed to said chassis frame, each motor having an upwardly extending power operated element, a stem projecting upwardly from each such element, and means for transmitting force from the upper end of each stem to said truck body to prevent upward movement thereof.

Claim 8

In a truck of the type described, a truck chassis frame, a plurality of transversely and longitudinally spaced seat means carried by said chassis frame, a truck body resting on said sheet means, scale means carried by said truck body and including a scale beam mounted to pivot on a hOrizontal axis, force transmitting means connected between all of said seat means and said scale beam whereby the weight of said truck body and the contents thereof will exert a force on said seat means and move said scale beam, and force applying means for preventing upward movement of the truck body relative to said chassis frame, said last named means comprises a plurality of motors at each side of said chassis frame, each motor being adjacent one of said seat means and fixed to said chassis frame, each motor having an upwardly extending power operated element, a stem projecting upwardly from each such element, and means for transmitting force from the upper end of each stem to said truck body to prevent upward movement thereof.

Claim 9

Apparatus according to claim 6 provide with stop means engageable with said scale beam to prevent one end thereof from swinging beyond a predetermined point, and a fluid pressure piston and cylinder means for transmitting movement to said scale beam to hold it at said predetermined point.
