A frame for a heavy-duty vehicle includes a pail of spaced-apart,
parallel, elongated, and longitudinally-extending main members. At least
a pair of transverse cross members extend between and are attached to the
main members, and each one of at least a pair of hangers is attached to
and depends from a respective one of the main members and/or the cross
members. A component is disposed between each one of the hangers and its
respective main member, or alternatively is incorporated into the
hangers, for absorbing the energy that is created by an extreme event
during vehicle operation, to reduce the possibility of damage to the main
members and/or the cross members caused by movement of at least one of
the hangers during the extreme event.
