Abstract
A trailer assembly comprises a main frame, main axles carrying laterally spaced wheels for supporting the main frame, a suspension system connecting the main axles to the main frame, a kingpin for coupling the main frame to a power unit, a secondary frame, one or more booster axles carrying wheels for supporting the secondary frame, a suspension system connecting the booster axle or axles to the secondary frame, and a booster axle connection system between the main frame and secondary frame for proportionately distributing weight or force between the main axles to the one or more booster axles. The booster axle connection system includes a lever arm extending forward from the secondary frame, a support arm extending rearward from the main frame, and a variably positionable pivot connection between the support arm and the lever arm providing a fulcrum for movement of the lever arm. The fulcrum of the lever arm may be varied in relation to the number of booster axles to proportion the weight distribution between the main axles and the one or more booster axles. The secondary frame is sectioned to allow addition or deletion of booster axles. Connections between the support arm and the rear of the main frame and between the lever arm and the secondary frame allow the use of secondary frame sections in various combinations with the lever arm and main frame.
