1-29. TRAILER ASSEMBLY. (See figure E-1.)

1-30. The trailer provides the base and mounting provisions for the check stand components and the APU. The chassis

frame consists of aluminum sheets welded into a platform on which the APU support frame and control console are

mounted. The chassis frame is supported on the rear axle by a pivot plate bolted to the chassis frame, and with drag links

mounted in automotive-type rubber bushings. The chassis frame is supported on the front axle by a plate bolted to the

chassis frame and secured to the axle with U-bolts. A towbar, pivoting on the front axle and controlling tie rods to the front

wheels, provides steering for the trailer. The rear wheels are equipped with a mechanical parking brake system,

connected by linkage to a brake handle on the left side of the trailer. The parking brake mechanical linkage is welded to

the fuel tank. The four, split-rim wheels are mounted with pneumatic tires and tubes. Tiedown rings and reflectors are

bolted on the side of the chassis frame.
