Hiya…how about a electrical fire on the unit !!! driver dosen’t want the load to go up in smoke.
drop trailer fast(just pull pin) them move unit away!!! do you bother with the landing legs or
just get out very fast. if you dump the air the trailer is almost on its knees any way.

Didn’t tesco’s have a couple of insidences like this a few years back that turned out to be because of dodgy king pins on a batch of new trailers.Surprise surprise, zb supermarket with zb kit…
Aren’t a lot of their trailers Grey & Adams? Anything but zb if so.
I very much doubt a king pin has failed
you’d have more of a chance of the Jaws failing.
When I first started driving Young Gordon Vickery at our place lost his trailer he’d had the same trailer on all week, apparently the jaws had broken and almost all the bits were missing ( Big D fifth wheel ) MoT and police were called as the trailer had hit a car coming the opposite way where it had detached, we all walked the 1 mile route back to the yard looking for any bits that could have been part of the mechanism nothing was ever found.
Jaws failing,are you saying Steve geeson was no good at his job,or kev( forget his second ) was also a crap Cnc miller,they used too mill the casting on a jig on there cnc mill,
At least you haven’t mentioned the top plates,I welde them up before they got a robot welder,sliders and ramps as well,then fitted top plates up,springs,adjuster rods etc when robot arrived.
Think Wordsworth holding sold big d onto jost in the end.
No Dozy I’m saying we had a failure of a mechanical part a fracture in the metal etc un seen.
In the days of yore, when ever we took a trailer for test, the fitter would run a stick welder down inside the jaws, it just stopped a bit of slap 
It shows that a fifth wheel rarely fails if it is coupled properly
