ABSTRACT:
A wheeled vehicle is provided including a trailer body and a tandem wheel assembly including a frame supporting a portion of the trailer body for relative longitudinal sliding motion with respect thereto to vary the longitudinal position of support. A pin locking system is carried by the tandem wheel assembly to selectively lock the trailer body and tandem wheel assembly in a selected longitudinal position of support. The locking system includes a plurality of pins mounted on the frame for movement between extended and retracted positions. A linkage mechanism is carried by the frame and is constructed and arranged with respect to the pins to move the pins between the extended and retracted positions thereof in response to movement of said linkage mechanism from an operative position to an adjusting position thereof. An actuating assembly is carried by the frame constructed and arranged to move the linkage mechanism between its operative position and its actuating position. The actuating assembly includes a manually actuated pull rod which operates a pneumatically actuated unit to move the linkage mechanism from an operative position to actuating positions to retract the pins.
