In the Aviation forum there is a thread about the Antonov 124 and a member who got a tour of it. The OP of that thread noted the AN-124 was being
used to transport some parts to a large crane to be used at a cracking plant in Pennsylvania. I thought to myself, wow that must be a heck of a crane
if they needed an AN-124 to move some of its parts. So I decided to go look up this particular crane. And yes, this is one HELLA BIG crane. In
fact, it's the largest crane in the World!
Now, I don't know about you, but I like to see big things, and cranes are just plain cool anyway. So...take a look at this beast! I promise, I
don't think this will be a waste of 2 minutes and 27 seconds of your life.
Imagine how time and money it takes just in the prep time? Looks like they have to clear and level an area to setup the crane and for the "skate" that
is attached to the bottom of the column to allow it to pivot. I wonder if it would be cheaper overall to build the column in place? I guess the
biggest factor would be the outside elements as they build it. Better to do it in a factory and then ship it.
They actually do build most of something like this on-site, but they have to build it on the ground and then lift it. One of the biggest reasons for
this is due to the QC/QA and testing required on all the welds.
