DEFORMABLE KINGPIN  that explains
a simple to understand solution to forbid a Tractor to follow into destruction
during Rollover events. The concept is the same as to why you have fuses or
circuit breakers in electrical systems in your home, office or car – a failsafe
– to prevent further destruction. This innovation is a simple modification of a
component, the Trailer’s coupling
Kingpin, whose design has been a standard for over 70 years, which can be
made to deform and not allow an extremely stable Tractor to follow to
destruction when the Trailer, that is the dominant controlling force, is in IMMINENT peril for Rollover, that
includes also blown over Tractor Trailers. The NHTSA & FMCSA continue to
turn their backs and ignore their past funded research conclusions, as the
trucking industry evolves greater unstable Tractor Trailers on our highways
that have a primary attribute for increasing payload capacity. These
Catastrophes will continue to occur in thousands of accidents of this type each
year as they have in the past, and continue to cause infrastructure damage that
will harm and kill many hundreds of Tractor occupants annually. These
combination vehicles are incendiary bombs when carrying flammable material in
Tankers, and the flash point for these fires starts with the Tractor’s
involvement. A statement received from the FMCSA states “There are a variety of
technologies for preventing Rollover crashes and we believe motor carriers
should have as much flexibility as possible in selecting technologies to
prevent crashes.” Clearly the fox is allowed to guard the hen house!!! The
harm, death & destruction will continue with combination vehicle Rollover
accidents. Donald J. Kaleta
