First off, use Google to find when Maxim's 18000 went down. Save you a spam post. Second, your approaching a very fine line. Better watch yourself. Lastly, Mammoet's a hell of a lot better than Lampson. Edit- http://www.kmbc.com/news/17431678/detail.html

The fine line I'm talking about is one you just crossed. I'm done talking with you on the forum. Lets berate each other over PM.

Slow down a bit everyone... Here is the Vertikal.net story and DHS post reguarding the 18000 collapse. - Chris

LOL!
Hope Lampson fails yet again. Man I hope not as I'm rather fond of Old Glory. Take or leave the big cranes but keep that 2570w up and running! Chris

I wonder if the mast had water laying inside the tubing and it rusted, and froze a time or two,thus weakening it and when all that downward force was applied the wall thickness couldn't take it.

Nope. Any mast or part of a crane boom will easily bend with external forces applied to it other than what it is meant for, especially when you consider the hundreds of tons of load on the mast.

Ryan, as far as I know the ONLY dragline incident that involved a Lampson crane was the 4600 Transi-Lift crawler crane in AU with the 8200.... Lampson has NOT dropped three dragline booms as the child rudely claims. ...
On another note, What is the matter with you "Mammoet Man"?? hoping for a crane accident??..... maybe people killed?... I can tell you this.... Your no "Mammoet Man".... no one that works for that fine organization would ever hope for a crane accident... from ANYONE, ANYWHERE, ANYTIME. They know better than anyone the tragedy involved. As a matter of fact, for the record, they have had failures and accidents also... Want to bet me on that ???.... How much??? I can show you some red iron layed all over the ground just like all the players in that line of work.It happens. Lampson is a good company and the cranes records speak for themselves. Have you got any idea how many big lifts the Transi-Lifts have made over the decades?? I do. Lampson has a fantastic record. Nearly ALL the few failures that occured involved operator error or misuse/abuse of the cranes involved.

I wish no company ill. Both Lampson and Mammoet do leading edge lift work. When accidents happen in very large work, the results are catastrophic and spectacular. This is why we now have lift plans and pre lift engineering to prevent bad things from happending.
Even when looking a spectacular and tragic failure such as Miller Park using a Lampson machine, the greatest responsibility rested with the company for whom Lampson was working and the least with Lampson. The Lampson responsibility was contractually assigned to the party for whom they were working, The crux of the Lampson issue, was when does the operator over rule the wishes of their customer. The managing party failed to consider the wind load.
Ask our forum members that operate lift cranes on a daily basis how difficult it is when they must stop a job and not serve a customer versus the support they receive from their sales and administrative offices.
Additionally when one has two machines sharing a load, the weight transfer between them is a very tricky thing. Any sudden unanticipated weight transfer of weight can upset the apple cart (crane) receiving the sudden weight transfer. What happens when their is further catasrophic failure of the already malfunctioning boom hoist and boom rigging on the mining? Many of these jobs are done under the direction of the mine's or refinery's engineering staff. Hence it is not solely a Mammoet or Lampson responsibility.
These issues go beyond a Mammoet or Lampson, but are issues within the crane industry that are under discussion from mamagement, engineering, operator and legal perspectives.

I would like to apologize for saying that Lampson fails. I stepped out of line and am now realizing the gravity of what I have done. That being said, Lampson does some stellar work and I hope the planned lowering of this dragline boom goes off without a hitch.

And I am curious about which cranes are going to be used for this lift. Any news? Kerst

I haven't been up there yet, but have heard the 1000 ton crane will have 8 crawlers, so that means it will be a Manitowoc 21000. I may have actually seen a couple parts of it heading North today while driving back home from work.

Here's a cell-photo someone took on site. Anyone know what kind of crane that is that's getting set up?  Redjack
