Abstract
A load transfer device for transferring a portion of the load normally carried by the rear wheel sets of a dump truck to the front wheel sets of the dump truck. The device is in the form of a tag frame which is pivotably mounted on the tailgate of a dump truck so as to be movable between an elevated position in which the tag frame is disposed closely adjacent the tailgate and a lowered position in which the wheel set of the tag frame is in the current engaging position.

In a dump truck having a dump body which includes a tailgate for closing the discharge end thereof, said tailgate being pivotably mounted at its upper end to said dump body and releasably latchable at its lower end with respect to said dump body, the truck having a body frame supported by front and rear wheel sets, the improvement of an axle load distribution means comprising,
- a. a tag frame having a front end and a back end,
- b. a wheel set mounted for rotation on said tag frame at the back end thereof,
- c. means at said front end of said tag frame pivotably mounting said tag frame with respect to said tailgate for movement between a first elevated position in which said tag frame is disposed closely adjacent said tailgate with its wheel set elevated out of ground engagement and a second lowered position in which said wheel set is in ground engagement and serves to transfer load from said rear wheel set to said front wheel set,
- d. loading means extending between the dump body and the tag frame operable to move said tag frame between said first and second positions.
A tailgate load transfer device for use on a dump truck to effect a load transfer between the front and rear wheel sets of a truck comprising
- a. a tailgate having an upper end and a lower end means at the upper end of said tailgate for pivotably mounting it with respect to said dump body and means at the lower end of said tailgate for releasably latching it in a position closing the rear end of a dump body,
- b. a tag frame having a front end and a back end,
- c. a wheel set mounted for rotation on said tag frame at the back end thereof,
- d. means at the front end of the tag frame pivotably mounting the tag frame with respect to the tailgate for movement between a first elevated position in which the tag frame is disposed in a face-to-face relationship with respect to the tailgate and a second position in which the wheel set of the tag frame is spaced a substantial distance from the tailgate,
- e. hydralic cylinder means having one end mounted on said tag frame and the other end mounted on said tailgate, said hydralic cylinder means being operable to move said tag frame between said first and second positions.
