I have never seen boom stored inside other boom for transport. Does the larger boom have some sort of composite bumpers in it so the smaller boom can slide in it? Thanks

Lots of KY.

its done in different ways depending on the OEM

Krupp had wheels that were installed with the lower jib pins ,and a sheet metal track to roll along inside the next larger section.

Liebherr and Demag use a Teflon bumper system combined with rollers and wheels .. its a little more tricky to load em in an out without having them run away inside ..
but on the bigger sections of both there is a roller and mid way a couple of little wheels to carry the section along. After its over center a couple of guys can finish pushing the section in ,, once stowed there's a chain and a pin to secure the section from rolling out , or just a pin to dog it in

good pics mate

what are the chances of knowing they were coming....

and forgive this little remark, in all friendliness, but when i saw your location i had to smile, because "optimized crane logistics" is something that other Wisconsin people should give a thought or two

4 Boom sections

well i guess for the size of that crane ,there should be a sizable erection crane to handle those lifts and still be able to shake out the parts. i mean ,of the hip , those lifts would have to be at least 10t metric..
your not gonna do to much with a 60t support crane in this case ,like you can the AC500 series , or even the M2250. i mean even on the CC2800 an 80t was full of her to get any amout of work done from one place, just barely get 3 sections at a time laid out and installed ,the jib ,or even the luffer became another story.
Even with the AC100 on the CC2500 it became a challenge to off load boom shake it out and still be able to load in stone. you can cantilever the boom but a fixed amount of stone is required for each move . and the the room to swing it around to load the stone ,, sometimes wasnt there

so to think ,from a perspective of being in the seat on a 80t,,and having that boom rollup on a truck ...its gonna get very interesting fast

if i swayed of topic sorry

I thought that all boom sections were the same size, and the only difference was the length...?

Check out the pieces on the AC500 luffing jib. There are some differnces in the sizes just within that jib. Boom/jib dimensions, and the size and thickness of the pieces that the sections are made out of, are in proportion to the size and capacity of the crane. Bigger crane = bigger boom. The restriction on size is transport. For example, the Lampson LTL2600 boom sections are too big to fit on a truck, so each section gets taken apart so that it's shipped in many smaller pieces.

Dave,
I just happened to be passing!! Seriously, thanks for the heads up on this one. Paul Simpson says he has only escorted one track in and he does all VDV work in this country yet VDV say the other track is there already, brought in by Van Wieren's 8x4 FH. You dont happen to know if it got escorted or not?

Cheers
Paul
