Few from the NE. Found on Facebook, not my photos
The Rank Flour Mills at Gateshead, is that the Baltic Mill, nowadays an art museum? And did the entrance drop down sharply from the road?
If it was, I loaded once there back in the 60s with my Kew Dodge artic and 26 ft Boden 4 in line flat. After I loaded I drove to the bottom of the slope and then turned right up it to the exit. Unfortunately on the Dodge the batteries were mounted on the chassis behind tha cab and, as the front wheels started to climb the slope and the corner of the trailer came down on the batteries and smashed them.
Nothing to do about it I headed home, of course you only needed batteries to start the engine and all the electrics were fine if the revs stayed up. I made it home to Nottingham that night but at each slow turn or traffic lights I had to keep the engine revving to maintain the lights. I was very glad to be home. 
If I had stalled it I would have been buggered.
