ABSTRACT:
A dolly distributes weight between a highway truck and trailer while at the same time maintaining an extended wheelbase between load bearing axles. A front end of the dolly includes a king pin that joins to a sliding fifth wheel located on the truck frame. A second fifth wheel is joined to the rear end of the dolly and receives a corresponding king pin on the front end of the trailer. A pivot assembly is joined to a center section of the dolly and is pivotally joined to a rear end of the truck frame. The pivot assembly serves to pivot weight between the front and rear end of the dolly and also maintains the dolly in a rigid longitudinal alignment with the truck. Air bags are located between the steerable dolly wheels and the the rear end of the dolly to further increase adjustability of trailer weight distribution.
