Hoynor Jumbo 80Cubic Yard tipper

I worked for Hoynor the Manufacturer of a 80 Cubic Yard Tipping Semi-Trailer in the Eightees.
I went with it on Loan to "Cleanaway"on test runs loadeded with rubbish out of North London and emptied at Land fill.
“Cleanaway” didn’t buy it and I wondered what happend to it,is it still in use? anybody know?
