Section II. DESCRIPTION AND LEADING PARTICULARS
1-3. FUNCTIONAL DESCRIPTION. The front and rear transporter assemblies (figures 1-2 and 1-3) are towed as a unit.
They are coupled together through the holes in each tine, using hardware supplied. In addition, a safety cable ties the
two assemblies together (see fig. 1-1). Once at the shelter site, the transporter assemblies are uncoupled and attached
to the shelter by special mating devices on the shelter and the transporter assemblies. Quick clamps on the front
transporter assembly provide storage areas for the coupling hardware when the transporter assemblies are attached to a
shelter (see fig. 1-4). The lifting jacks are used to lift the transporter and its load to travel configuration prior to
attachment to the tow vehicle. Additional quick clamps provide storage areas for the jack handles when not in use. The
tow vehicle can tow the transporter at speeds up to 50 mph on paved roads and up to 15 mph on unimproved roads.

(common to front and rear assemblies); front axle group; rear axle group; brake group; and wheel group.
