ing bolts should be removed from the tongue, allowing It to "Jack-knife" and lie on the floor of the car. Also, the
tongue of front trailer on both levels should be removed and secured in the body of the trailer.
Apply chain tie-down parallel to each other at the same end of the vehicle and down from the trailer point of
attachment to the rack tie-down channel at approximately a 45 degree angle. Care must be exercised to ensure
that the tie-downs are properly tensioned, all slack is removed and tie-down devices locked.
Tie-downs when installed shall not come in contact with electrical wiring, vehicle controls and other
Hand brakes must be set on each trailer.
Open hooks must be secured with wire over the openings to prevent the hook from becoming disengaged from
the chain link to which it is secured.
Turnbuckles when used to tighten chains must be wired or locked to prevent them from turning during transit
unless the turnbuckles are equipped with self-locking devices.
Twenty-four trailers can be loaded on a bi-level car having an 87-foot long usable bottom deck and an 86-foot- 6
¾ inch long usable top deck with continuous center tie-down positions running the entire length of both decks of
the rack. Twenty-two trailers can be loaded on racks of shorter length than shown above, but in excess of 80 feet
in length. For all loadings, trailer axles should be spaced approximately 7 ft. 1 in. apart.
The numbering sequence of units starts from "B" end of car, either deck.
When cars are equipped with racks designed to allow longitudinal movement between racks and car, precaution
must be taken to provide for clearance of load and securement over fixed portion of car.
