<p>APPLICATION OF: Derek K. Keene; James A. Wahl FOR: STEERING AXLE ASSEMBLY PROVIDING IMPROVED LATERAL STABILITY An axle assembly is provided for a load lifting vehicle, the assembly including a main frame, a vertical central plane, and a secondary frame extending transversely to the main frame. A first support frame is fixedly attached to the secondary frame and carries a first pivot means. A second support frame is fixedly attached to the main frame and carries a second pivot means, the first and second pivot means being oppositely disposed about the central plane. Link means connect the first and second pivot means permitting angular movement of the main frame, with respect to the secondary frame about either of the pivot means. The angular movement about the oppositely disposed pivot means provides the vehicle with a widened stability pattern.</p> |
