Got another one. Same second loader, so again I know its true. Off highway shows up to get loaded late in the day (I believe it was a Hayes and they were running mostly KW's). Montreal and Boston in the playoffs (so this puts it at late 70's). The second loader and loader operator want to get to the local watering hole to watch the game which would have started at 4:30 our time. They throw a load on and last second my buddy remembers to pull the pin releasing the compensator (second loaders job) get in their pick up and get ahead of the slow moving truck.
Next morning they get called into the office for a bit of a dressing down. I guess in their haste, my buddy pulled the wrong pin and pulled the pin releasing the hitch all together. Driver crawled down the mountain side and trailer followed nicely. On the better roads of the valley bottoms he pick up a bit of speed and get to a large dip in the road and puts his foot into it to climb up the other side. Bang, looks in rear view and all he sees is logs coming his way and they are cartwheeling past him in the ditch.
Second loader and operator had to go to crash site, walk all the way to their machine and walk it out to the truck. pick load apart, get trailer out of one ditch, truck out of the other and reload. My buddy said they had one long day before they had the machine back at the landing.
That was the drivers last off-highway load. He only drove highway after that before retiring a few years later.
I guess the K/W and the Hayes had different compensator pin locations as well as a pin that releases it all together. On one it was vertical and other horizontal and he just pulled the wrong pin releasing the whole shebang.
