ABSTRACT:
A locking system for locking a tandem wheel assembly of a wheeled vehicle with respect to longitudinally extending members of a trailer body. The locking system includes a plurality of pins mounted for movement between extended and retracted positions. The pins engage within selected openings in the extending members. A spring is operatively associated with each pin for resiliently biasing the pin into the retracted position thereof when in an unstuck condition. The locking system also includes a linkage mechanism constructed and arranged (1) to move the pins from their retracted positions into their extended positions within a selected opening against the resilient bias thereof in response to the movement of the linkage mechanism and (2) to allow movement of the pins from their extended positions into their retracted positions to occur by virtue of the resilient bias thereon (A) when in an unstuck condition and (B) when in a stuck condition at a time after the movement of said linkage mechanism from an operative position to an adjusting position when the stuck condition has been changed to an unstuck condition.
