The C2 is a body-mounted liftgate that
put forces on the side walls of truck bod-
ies (FIG. 6-1). For correct installation,
truck bodies must be strong enough to
withstand the tension, compression and
shear forces shown in FIG. 6-1.
X= Tension on each sidewall
Y= Compression on each sidewall
Z= Shear on each sidewall
Consult vehicle body manufacturer for vehicle body strength data. Make sure the
forces created by the Liftgate are within the limits prescribed by the vehicle body
manufacturer.
WARNING
