fifth wheel semitrailer couplings
fifth wheel semitrailer couplings
(OP)
I have come across many different configurations that exist for fifth wheel couplings on semi-trailers (articulated trucks to us Brits). I have also found jargon words which are not self-explanatory and are ambiguous.
Is there a good reference website out there which covers 5th wheels? This is a new area for me and I am confused by this extraordinarily commonplace and simple technology!

RE: fifth wheel semitrailer couplings
You may want to look at information on Holland Group's website: www.hollandusa.com.
Also, there are Commercial Item Descriptions (US MIL-Specifications) for the Kingpin (A-A-52478) and Fifth Wheel (A-A-52544); you should be able to find these for free by searching on Google.com.
SAE (www.sae.org) publishes SAE J 700 Upper Coupler Kingpin-Commercial Trailers and Semitrailers and SAE J 133 Fifth Wheel Kingpin Performance-Commercial Ttrailers and Semitrailers as well.
Hope this helps!
