LOCATION AND DESCRIPTION OF MAJOR COMPONENTS.
a. The flatbed trailer includes the frame, lunette, suspension system, air brake system, leveling jacks, and
lighting system. The flatbed trailer frame is a welded steel structure comprised of channel members welded to a 7-gage
steel decking plate on the XM1034 and a 3/16 inch plate with a center strip of mesh expanded metal on the XM1048.
b.
Intervehicular safety chains (fig. 1-1) are secured on the drawbar adjacent to the lunette.
c. The suspension system (fig. 1-2) is a tandem axle, leaf spring arrangement attached to a trunnion axle
which is mounted to pedestals on the trailer frame. Each of the four wheels is equipped with mechanical shoe-type
brakes actuated by the air brake system with air supplied and controlled by the towing vehicle.
d. The air brake system (fig. 1-3) consists of "Service" and "Emergency" Intervehicular hoses and couplings,
air filters, air reservoir, emergency relay valve, four air chambers, and connecting tubing. The Service line provides
control air and the Emergency line provides supply air. Metal tags on the anchor couplings identify the towing vehicle
outlet to which each hose is to be connected. The service brakes are expanding shoe and drum type. Air pressure for
brake operation is supplied and controlled from the towing vehicle.
e. Hand brake levers, located on each side of the drawbar, (fig. 1-1) connect through cables to the slack
adjusters on the front axle. The slack adjusters serve as a means for setting the clearance between the brake shoes and
the brake drum. Adjusting knobs on the ends of the hand brake levers tighten the cables, which in turn tighten the slack
adjusters.
f.
Retractable leveling jacks (figs. 1-1 and 1-4) are located at each corner of the trailer deck. These jacks can
be retracted for trailering or extended and individually raised or lowered to level the trailer bed in all directions. A
removable hand crank is used to raise or lower the jacks.
