Re: Car & truck fishing
seriously this guy shouldnt have even been near a truck crane. ive had a bit of experience with them and if you dont know the full physics of them, there is a huge potential for disaster.
my old neighbour used to have one strapped to an old bedford and i used to help him out a fair bit, anyway one day we drained and changed the hydrolic oil in all the rams and the main tank (as per manual) and re filled back to the Full mark in the tank. the main boom was fully extended so he fired the truck up so we could get all the hydrolics full again, and it went up ok (about head height), and then it went around to the right (as we were on the slightest slope) but no one had pulled the lever to do this though. we stood there and watched as the fully extended boom swung around straight for the side of the neighbours house waiting for it to plow through it and destroy half of the building as it wasnt responding to the levers to make it stop. the truck was on a huge lean (legs werent down) and we were just waiting for the house to collapse and the truck to roll over and probably crush us both. (this all happened in about 2 seconds mind you).
we were VERY lucky that day, it missed the house (by only 10cm) and the truck didnt roll.
refilled the tank with more oil as the initial 'lift' had drained it and got the boom back onto the bed of the truck and went back to the service manual.
moral is: if you THINK you know what to do with heavy machine just because youve read what to do, then you probably dont so STAY AWAY.
