The messed up thing is that I also had the service brake lever set when it was on the trailer, and it was in the engaged position as it was rolling down the hill. So I had both the parking brake and service brake set...
Would it be possible for the service brake to bleed off while bebop-ing on my trailer down the road? It is an old rock truck.
When I was a kid and doing one of my first moves I did that in reverse and went off the back of the trailer. I went to pick up a TS 24. Got it started had air made a quick uball to line up with the trailer.
Drove up to the nose and she didn't want to hop up. I looked over at the Cat hand and he made a running motion, like get a little run at it. At the time missing from my knowledge of cans was the fact that
just expect it does not have brakes. That would have been a good thing to know as I got my run at it got the tractor up and stabbed the break pedal... and as C W McCall said "it was kind like stepping on a plum'"
The tractor bounced up on top of the axles and right off the end of the trailer and we stopped in a hurry when cutting edge/apron hit the step... I looked at the Cat hand who at this point had came to a stop and
was laughing so hard he was crying. After everybody had got a good laugh at the dumb girl and the flying 24, he gathered himself together enough through continuing gales of laughter to shove me and the tractor back
up on the trailer! In a quarry I used to frequent there was a a little sign on the roof of the office. It said "Stay alert, we need live alerts." Glad you were OK!
