PS...must reiterate that I think the Andersen design is elegant, but as with
all things...it is only as good/strong as the weakest link
"The devil is in the details of any design"
In this case, IMHO, it is the latch assembly...which was never designed for this
kind of service. It's duties mainly reside in keeping the ball inside the globe
with 'some' dynamic forces from the trailer pushing/banging into it or while
going backwards
In going backwards for the original design criteria...how fast do you
suppose the specifications were for in MPH? How many service miles?
Service miles as being warranty and that then goes to the MTBF in that
condition(s)
100 miles at the full forces? 1,000 miles? Surely not tens of thousands, right?
Of course to hold during an accident and Ron provided those numbers
and links they are held to by the regulatory agency(s)
