Thank’s Robert.
Power lines, now that was yet another thing we had to contend with! We had a couple that ended up with all the tyres and brake diaphragms blown out but luckily the drivers escaped injury as they stayed in the cab. I seem to remember a lad on Plant’s from Tean who was tipping in a field and he jumped out but still had hold of the cab when his feet touched the ground, killed him alas. 
Phone lines could be a pain in the arse as well, body up and down between then while being pushed with a paver but at least id didn’t kill you if you caught one. I was tipping at BL in Longbridge in the eighties (one of Tilcons own gangs as well) and was warned about the computer cables overhead by one of the staff: “Of course I’m not going to catch them” I replied, disgusted that he should think that I would. However… I backed onto the paver and the driver was sitting on the right so I lined myself up with the machine and he started pushing me…then suddenly locked over to the left! He had changed sides!! 
Well you can’t get an eight wheeler Sed Ak with supertanker steering lock to change direction rapidly, I became wedged on the machines pan sides and couldn’t drop the body and he still carried on shoving me sideways! Anyway I was empty and tried to draw off but was stuck fast. Driver and ganger started shouting, so I drew off leaving part of the mudguard behind. They couldn’t give a toss of course. 
When I jumped back in the cab I noticed cables draped across the body, I had ripped the bloody cables down! I chucked them in the body, cleared off back home and never heard a thing about it! 
I learned then that some gangs must get up in the morning with the sole intent on making a drivers life hell every day. 
Of course this was before they used banksmen and you were very much on your own to fathom things out.
Pete.
