It also appears like the main boom was pretty low when they tried to lower the upper jib creating a long lever.
Isn't it incredible that only 1 person was killed with 500+' of boom and jib falling in the city?
How large of a CAZ is typical when using a crane of this size?
Another thought I had was I didn't see a wheel horse on that rig. Is that something that could have been necessary for that size of rig in those conditions?
I was just looking on instagram it seems that they had two of those cranes (the same model)in one of the pictures it showed two steel wheels on the tip .It also had a pic that said they had the street closed for 72 hr's strait to assemble it .Someone made a comment that they where trying to get it down because of wett sticking snow/ice and high wind condition's. At least it fell down the street and not across or through the buildings most likely would have been a lot more people hurt or killed. I also thought about having to bypass the safety/overloads if you have ever seen one of those go up it looks like it's almost a seat of the pants move to feel when to start lifting the jib off the ground imagine trying to let it down in high wind and icing conditions. Also seen a comment that it took 30 trailer lds.
Now I have never been known as a brain surgeon but my biggest issue is this. Who the hell thought up the plan to put over 500 feet of luffer and boom configuration in a 1300 Liebeherr. (1300 are a 300 ton class machine) Just because liebeherr says it can be done does not necessarily mean lets do it in the middle of Manhattan. My point being when you max out a machine with max stick and jib every thing needs to be perfect. The fantasy land that I live in has so many pitfalls. I wish every one the best and my sympathies. But god Dang management pull your head outta your rear.
OK, what is a better alternative to a crawler with a luffing jib, to lift stuff on a narrow street in Manattan? Is there something better that is temporary?
