LOCATION AND DESCRIPTION OF MAJOR COMPONENTS (CONT)
APU AUXILIARY START CABLES (20.1), SAFETY CIRCUIT MODULE (21), AND STOWAGE BAG (22). A set of
auxiliary start cables (20), and a safety circuit module (21), hereinafter referred together as the jump start system, can be
used to supply 12 Vdc battery power from the tractor batteries to the APU when the APU battery does not contain
sufficient charge to start the APU. The cables, when not in use, are stored in a bag (22) which is stowed under the
platform steps. The safety circuit module (21) contains a switch, relay, and voltage sensor which permits a maximum of
12 Vdc to be applied to the APU electrical system.
PLATFORM ASSEMBLY (23). The platform assembly (23) is a flatbed-designed structure with a beavertail, the slanted
portion at the rear of the trailer upon which payload items are loaded and unloaded.
PAYLOAD TIEDOWN RINGS (24). There are six tiedown rings (24), affixed at various points on the platform, used for
ISO CONTAINER LOCK BRACKETS (25). There are eight ISO container lock brackets (25), normally stowed recessed in
the center of the platform, used to secure ISO containers during transport. There are three types of ISO container lock
brackets: curbside, streetside, and center. The types are identified by physical characteristics and markings. The
streetside and curbside lock brackets are marked "streetside" and "curbside", respectively, and have only one F-pin
attached to them. The center lock brackets are unmarked and have two F-pins attached to them.
TRANSPORT TIEDOWN RINGS (26). There are 10 transport tiedown rings (26), five along each side of the platform,
used for semitrailer tiedown during shipment.
CARGO TIEDOWN RINGS (26.1). There are 14 cargo tiedown rings (26.1), affixed at various points on the platform,
used for payload tiedown. When not in use, the cargo tiedown rings lie in recesses to prevent damage by tracked
