My first thought was that it was some type of luffing jib crane...and it looks like that may be the actual crane designation:

I've watched one of these get wrecked pretty good, it was "boom whipped" by a broken choker at a real high angle, and came over the top to about 5 degrees negative....... and stopped.

That rig has been the workhorse of the construction industry for decades.
Manitowoc 4100 Vicon. IIRC, 230 tons basic capacity, but stick it on a ringer and the capacity goes to about 300 tons. (that's a 4100/W series 3, not the series 2 in the pic)
GOOD cranes, perhaps the best built crawlers in the industry...and the "little brother" of this one"

APE vibratory hammer.
Things started moving right along....too good.
They decided to set aside the hammer and hook onto it with the main block and an 1 3/8" choker. Boom was above 75 degrees, and they did not hook the whip into a nearby ecology block. When the choker snapped, it went over center, busted the stops and the cab glass, and both blocks went through the boom lacing. Just a little more energy and it would have landed on the Amtrak main line bridge over the river.
I was on an island mid-river with the superintendent about 50 yards away, setting a crane mat with one of these.
I'd never seen anyone really throw his hardhat before

Oops...Dammit, I hate it when that happens. (but I've seen similar "OH SHIT!" accidents before.)
Her accent is fucking annoying to me...but at least it's slightly better than when I call tech support.

35 years or so ago, I worked for Andrews Equipment in Spokane. They were a Komatsu dealer. You DO know that Komatsu is the japanese word for Motherfucker, don't ya?

Because cheaper labor is always better...:roll:
The biggest expense in that whole accident is gonna be the loss of the cranes and beam. The loss of life is probably no big deal in such an overpopulated 3rd world country as this.

What does it look like? Sounds fun!
Oh those D9's are pretty big. A few years ago a guy hardened one with plates and terrorized a Colorado town. It's on youtube - search for killdozer. :Q

Anyway, here's some youtube vids of vibratory hammers at work:

Not very exciting to watch...but a good crew can drive a lot of pile in a day with the right hammer for the soil conditions.
