Abstract
Abstract An apparatus for selectively positioning the sliding suspension frame or bogie relative to the trailer underframe including a bogie-locking assembly having handle and linkage operated springloaded locking pins for registering with holes in fixed suspension rails attached to the trailer underframe wherein the handle is provided with a latch pin which is held against a slotted latch plate against the action of the locking pin springs, the handle having a rotating dial, which indicates the desired amount of bogie shifting, positioned to be rotated by a star wheel driven by movement of the trailer frame relative to the bogie such that when the trailer has moved a sufficient distance, and the star wheel thereby rotated, the latch pin on the handle is allowed to pass through the slotted latch plate to permit the locking pins to engage the openings in the fixed suspension rails to prevent any further relative movement between the trailer frame and the bogie.
