"Jon Grimm" wrote in message news:eAPnd.2002$K36.1556@trndny03... Palfinger and related type booms always fascinate me. We have a grove TM12T, and I enjoy operationg it, but always err on the side of caution. When setting up on soft ground, I always build cribbing into pads that are 3 x 3 feet. Seeing the amount of list that one pic shows, the operator had to know this was inevitable. And the second pic shows clearly the tire either about to come off the ground, or already in the air.

Look picture to picture and see if you think those people who were standing
in the way of the truck went in the water. There is a guy in a tan shirt, a blue jacket, and a red jacket that I don't see in the after picture. I have hoisted a bunch of stuff, and it always amazes me at the absolutely stupid places people will stand while you are doing it. Even those with some experience in the field. Steve |

In article , Dave Mundt says... However, as to the fountain below the pole-vaulting crane in the 4th picture....Look closely at the car. It has fallen kind of sideways into the drink (again), and, I suspect that the fountain is actually a blow of water vapor coming up through the engine compartment, and being focused by the sprung and twisted hood. There's no hood back there - and the color is wrong. I think the fuel tank was ruptured during the slide across the stone wall edge. I was kind of amused by the fact that the guy in the gray shirt, "supervising" next to the red-shirted operator totally vanished between the 3d and 4th frames. He apparently decided that he was a bit TOO close to the flipping truck. Yes, I noticed that - though I thought his jacket was blue instead of gray. Sort of blue-gray. But he comes sauntering back from stage right after the fact. What bothers me a bit is, where are the controls for that boom? There had to be an operator, and I cannot see him on the landward side of the crane, so I suspect the hydraulic controls are on the sea side. And I didn't see anyone go in the drink - so he must have had time to get away. My suspicion is he's the guy closes to the edge, wearing all dark (brown/black) clothes, peering over the edge in disbelief. I bet I know what he's saying, too.... Jim If you blow it up, and find the figure who was closest to being pinned by the rolling truck, the gent in the coveralls and red shirt, he goes from being front and center looking at the hood of the car, to way back behind the falling truck. That took time. He had to run around the truck. It didn't overturn that fast. |

That reminds me of when we were having a cess pool blasted out. The blaster
suggested we hide behind the truck with him and his assistant, so we did. Then my friend decides he's going to stand where he could see the blast from what he considered was a safe distance, the side of the truck. He was fine, but it would only take one little sliver of rock to get past the chained together tires, they covered the blast with, to ruin your day.

In article , Don Murray says... So, what I think happened is that his load shifted. You see the way the sling goes through the 2 doors, I think it slid to the back side windows, causing a shock load, tipping the crane over. Interesting theory. The second pick by the green crane supports it, because it's obvious the car wants to be nose-heavy and the sling wants to slide back as far as it can, to the rear of the front windows. Naah, that's not it. Look at the fourth picture. See that dog on the right? He was on the truck during the hoist . When he jumped off to have a sniff around he unbalanced the whole thing and over she went. Look at him standing there wagging his tail like nothing happened. Looks like the guy in the red & black jacket is going over to kick his ass. -- Drew |

Those have zillions of marble sized hard balls on them. They had one of those huge chippers on the back of the truck. There were about three men standing forward of the centerline when they tossed in the first branch with chinaballs on them. ZING ..................... they went shooting like buckshot even though they had it fed into a hopper. They all ducked and ran, all of them being hit by balls at high velocity. They all stood behind the truck for the next salvo. I was picking up chinaballs for weeks all around the cul-de-sac. Funny how fast people move sometimes. Steve |

Oh, what a wonderful thread this is turning out to be
http://monkeyup.my-bulldog.com/pages...com/Ooops.html my question is dealing with the amount of twist in the first truck. While it has been noted that the front right wheel is almost off the ground in earlier photos, where it is flying off the quay the rear end is not in the same plane as the front wheels. Did a rear outrigger collapse or puncture through the ground? If so, why can I not find any shoring or other platforms being used? Especially with the green unit, after the first trouble? The twist seems to be entirely gone (well as much as I can discern) after the water bath, so it evidently was not to the plastic limit of twist! Oh, and we know how the truck got into the water, how did the car get there? From the dents on the front of the hood and the roof, it appears as though it drove forward into the drink. Front glass is broken when being picked up the the smaller rigger. If so, did it then rotate backward, to engine first and sink, resting finally on it's tires? If not, when would it have been righted? Just wondering Bert |

Couldn't this mess have been avoided by *backing* the first crane to the wall,
then reaching rearwards? Yes, I agree the car is parts. No way you risk your livelihood on pulling trash from the water. Maybe he didn't let it drain well as it passed the interface.... I would have *loved* to see the second crane go dunkers.... I remember once I had to get my cab hauled when I dropped a little old lady near to her door on an icy hill in Herndon. No matter what I did, I crept downslope so at some point I braked it and radioed in before I went over the embankement turtle fashion. Of course, I don't drive for *them* any more. Saved the cab, though... Those were the days. Money changed hands every day. Drops in a bucket. I tolerance everything and tolerate everyone.

If it was freshwater and there was no structural failures in the engine, just drying it out and purging the fuel system should get it going. If if was sal****er, I would think that it would never be the same. You'd have to wash everything in freshwater first then carefully dry it out. I would suspect it would be plagued with electrical problems for the rest of it's life. Of course, if the water ingestion bent rods or cracked the head or damaged the mains, all bets are off as well. |

Hey Mike,
On Mon, 22 Nov 2004 11:33:30 -0500, Mike Patterson wrote: On 22 Nov 2004 11:18:01 GMT, (HaroldA102) wrote: The first truck did not have outriggers Look again at the pic where the truck is upside down. It's clearly silhouetted against the gushing deisel fuel. If you say so, but it looks more like water than diesel to me Also in the pic before it tips over the outrigger is planted on the seawall. Again if you say so, but I can see no indication of out-riggers. I do see a series of what I would call "stanchions" spaced along both that sea-wall and the one perpendicular, and possibly used as bull-heads for the marine vessels to tie-up to. The one closest to the truck, mid-way along the sea-wall, sure looks like an out-rigger at first glance, but seeing the others makes me think not. Besides, it is still there after the truck flips in. And surely if the vehicle had outriggers, they would have been deployed, if for no other reason than to keep the truck "level" on the sloping grade before even starting work. Mike Patterson Please remove the spamtrap to email me. "I always wanted to be somebody...I should have been more specific..." - Lily Tomlin Another thing that hasn't been discussed is that in the first pix, the white car is upside down in the water, and I assume laying hard aground. Sometime between that and pix 2, the car is righted. It is hard to tell in pix 2 and 3 whether the roof was damaged from the initial fall into the water, or whether the **** poor slinging/rigging (with-out a spreader) is crushing the roof panel causing the strange looking "widows peak" appearance of the front of the roof above the windshield. I tried very hard to "see" the roof condition towards the area near the hatch-back in these early photos, but it is inconclusive to me as to whether or not it has sustained much damage (which bears on my argument later). It also seems to me that this first "recovery vehicle" does not have a winch. (Even on the second truck, the winch is "boom mounted"). That means that all the work has to be done at "sling length" and using the end of the boom. I suspect that the guy in the Zodiac hooked the sling around one of the visible wheels and they first "rolled" the car over, allowing the sling to then be placed around the roof. This would also put the truck "out of position" for the events following. I think that as the car was lifted clear of the water, the truck was right at it's limit. Note the terrific twisting of the frame. And I suspect that as the car got to near level with the dock, the operator tried to "swing" the boom to get the car on the back deck. Due to the truck not being level, ANY traverse motion, or worse yet, quick stopping of the traverse motion, will put enormous side loads on the boom and truck, and I suggest that this is what caused the truck to "tip-over". I think that as the whole thing went over, the car went into the water up-right, with the boom end coming down on the roof near the rear hatch-back, and then as the car stopped its descent and the truck continued, there would have been a rapid re-orientation and alignment of the twisted frame, causing the truck to spin and to literally do an action that is a cross or combination between a high-jump and a pole-vault, right into the sea. Just the motion of the now unfettered rear deck would have been a sight to get on slow-motion camera!! The real question to me is how the guy got a license, and how there were no on-lookers swept over with it. Even with the second truck about the only safe guy there is the cop!! Take care.
