Guest Posted February 18, 2013 Report Share Posted February 18, 2013 My proposed solution is to drain the pound then chop it up with the gas axe. I can't imagine the value of the crane approaching anything like the cost of a solution that recovers it complete and re-usable, so it is an insurance write-off. Get rid of it in the cheapest way possible. MtB That sounds the most feasible way to me. Surely the thing will be knackered anyway? Link to comment Share on other sites More sharing options...
Peter Reed Posted February 18, 2013 Report Share Posted February 18, 2013 Big problem with dismantling crane - it's upside down and underwater! Even draining the pound would still leave it upside down and really only dismantle-able with a hot axe. I can't see any insurance company being too happy about writing off one or two hundred thousand pounds worth of tackle for want of a bit of application. It strikes me that the best way of recovering it would be to roll it over, no crane needed for that. How would you roll that crane over? Link to comment Share on other sites More sharing options...
John Holden Posted February 18, 2013 Report Share Posted February 18, 2013 How would you roll that crane over? A couple of winches like what they use to right overturned big rigs. Link to comment Share on other sites More sharing options...
Jerra Posted February 18, 2013 Report Share Posted February 18, 2013 How would you roll that crane over? I know absolutely nothing about these things but my idea would be attach a long girder to the canal side of the vehicle pointing up into the air. Attach "ropes" (OK I guess hawsers would be the correct term). Inflate bags underneath while winching using the leverage of the girder. Possibly consider "ropes" from the other side of the canal so that you could start to lower when past the tipping point. Now I wait with interest to be told by those with practical experience why it won't work. Link to comment Share on other sites More sharing options...

Pembroke Posted February 18, 2013 Report Share Posted February 18, 2013 You have to remember this thing weighs 64tonne so this is never going to be easy I doubt air bags would have any real impact The crane will now be firmly embedded in the canal so breaking that suction seal could be difficult - bit like pulling your wellies out of the mud but on a bigger scale I think a winching operation could work but it will need some serious winches / rigging and anchor points which will require a fair amount of prep work Link to comment Share on other sites More sharing options...

boathunter Posted February 19, 2013 Report Share Posted February 19, 2013 I bet it still works even though it's half submerged. It could pull itself out. Link to comment Share on other sites More sharing options...
Jerra Posted February 19, 2013 Report Share Posted February 19, 2013 I doubt air bags would have any real impact I have seen what my brother describes as a "red appliance" (fire engine to you and me) righted by very few air jacks (2 or 3). A 5 tonne jack is 39" diameter so you could fit a number underneath and then there is the effect of the water buoyancy. OK t hey wouldn't lift very high but the water isn't deep and they would help with the hardest part. Just my opinion theorising. I am interested in the replies to compare my theories with peoples practical experience. Link to comment Share on other sites More sharing options...

SamKingfisher Posted February 19, 2013 Report Share Posted February 19, 2013 I went to have a look, and have some photos I'll try and post. It's a mess. Access is terrible. To complete the manoeuvre they'd planned, the beast had to go right on the edge of a naff bit of towpath. There was only going to be one outcome of that . . .

luctor et emergo Posted February 19, 2013 Report Share Posted February 19, 2013 Sounds to me like the driver was either instructed to do so, in which case somebody is in big doo-doo, or the driver drove there on his own accord, in which case he can kiss his bonus for the month goodbye (and his job).

I gather that ton bags of stone had been put in the canal bed to 'reinforce' the towpath, but clearly it was nowhere near sufficient. I expect the crane will be cut up in situ.

Pluto Posted February 19, 2013 Report Share Posted February 19, 2013 A few photos for those who don't know the site. This is where the crane has fallen in: The access to the maintenance yard along the towpath. The crane fell in a couple of hundred feet beyond the locks. The derelict swing bridge, with the locks and maintenance yard beyond. This would be the logical place to put stop planks. Link to comment Share on other sites More sharing options...

BEngo Posted February 19, 2013 Report Share Posted February 19, 2013 Actually air bag jacks work very well on soggy ground but I think they would have problems moving 60 tons. Not at all. The 777 that landed short at Heathrow a few years back was shifted with airbags- it's a standard technique for moving large aircraft back onto firm ground. The crane would no doubt need some pretty big ones. N Link to comment Share on other sites More sharing options...

Edit Just to add a meter square air jack would lift that crane by its self http://www.ameintl.net/products.php?cid=4&catid=26&Air%20Bag%20Lifting%20Jacks Edited February 19, 2013 by ditchcrawler Link to comment Share on other sites More sharing options...
bizzard Posted February 19, 2013 Report Share Posted February 19, 2013 One and a half million Helium or Hydrogen filled toy balloobs on strings would raise it, give or take one or two, nice red ones to match the vehicle. Or the same gases with roughly 798 bouncy castles or 4,187 inflatable dolls to draw the crowds in to watch. Link to comment Share on other sites More sharing options...

I think the Russians may have some with a bigger capacity? Tim Edit - they'll lift about 20 tons, still nowhere near enough http://en.wikipedia.org/wiki/Mil_Mi-26 Tim Edited February 19, 2013 by Timleech Link to comment Share on other sites More sharing options...
