Preparation
1A) Assembly Must Be Performed On Level Surface
The system’s framework is very heavy.
1B) Truck Ballast
Use a bubble level to verify that the truck is parked on a level surface. The truck shall be as close
to the final driving weight as possible. If ballast must be added to achieve the minimum weight, add
it at this time. Ballast must be properly anchored to the truck to keep it in place during an impact.
Ideally, an adequately sized truck, that requires no ballast, should be used. Because the 910
kg weight of the rearward protruding TMA is supported by the back of the shadow vehicle,
care must be taken not to exceed the manufacturer's published maximum axle loads. To ensure
that the driving characteristics of the vehicle are maintained, the manufacturer’s recommended
center-of-gravity zone shall be followed completely.
2) Interference Check
Before attempting to assemble the Underride, check for interference concerns.
The TMA folds so the Impact Face is very close to the mounting location ( p. 24, Figure 25) . If you
are not using a standard Socket Receiver Hitch Underride skip to Step 8.
Temporarily position the Underride Socket Receiver under truck frame as shown (p. 13, Figure 8)
and check for interference concerns. Interference concerns with tail lights, springs, dump bodies
(in the folded or unfolded positions), etc., shall be corrected before proceeding.
