Kind of like Jaws "We're going to need a bigger boat!"
Seriously under-gunned. But they got it.

More biners!!!
True that. They got a hard job done with what they had. Give them credit for that. Easy to armchair.. hard to be there and do the work.

That was embarrassing to watch. I had to stop the clip twice, walk away and chill a bit, before continuing.
But like Jer says, they got it. Lucky to have done so, imo. Proper tools, that's a 15 minute job.

Stranger things have happened, but I'd bet $1,000 that it would take 16+ minutes

Don't continue to waste our time with your drivel, Daniel. We'd all appreciate it.

At least out of their lane fallers.
Biggest I've done was 7'. A 50" or 60" cannon bar made it easy enough.
Full-gap face with a snipe might have been way easier.
Right size bars, easier still.
Still not 15 minutes, in my estimation.
Shouldn't have been 10 hours.

If there is a constant in this game, it’s that people constantly underestimate the weight of the ‘crown break’ of a trunk like this.
Guys face says it all.

I can't see the vid from instagran, as usual, but the still pic tells enough.

In such scenarios I've always wondered why the operators never let the work go. I mean, let the winch free-spool. Either way something is going to get damaged, but least you'll save the rig, and anything it could have damaged as a result.
I guess mentally, after years of training, it's hard to just let go willy nilly.

Is that a modern crane possibility?

I always told the Ground that if the rare occurrence that something is somehow totally f ucked up to the point of someone mebbee getting hurt ... Let go of the rope

I wondered that, too, Sean. Maybe interlocks wont let you kick the winch into free-spool.

How about a super strong spring loaded knife to cut the cable. Hit the panic button and drop the load. But what would that do to the crane to release all that tension? Sling shot it over backwards?
I saw video of the proof load of a new crane, huge crane 3800 ton or some other massive number, that shot over backwards. I believe the main hook broke.

Who knows for sure? Any body?

Yeah, that's what I was thinking free spooling probably not an option. Even if you could, the rat nest of cable may just hang up like a bait casting real?

In some scenarios a backlash may be the lesser of the two evils.
Is there a governor preventing how fast you can lower a load with a crane?

I'm not an operator so i don't know for sure, but i think most modern cranes, especially hydraulic ones, are not able to free fall the load. Free falling is very very hard on a crane, and the jobs that would require that like demo work are considered duty cycle work, and can only be done by lattice boom cranes because of the rapid unloading that would whip a cantilever boom to pieces.

You are probably right Kyle

notice the delay there.. I've seen the same thing happen in limb failure. Limb takes a big hit.. hesitates, then some seconds later it fails

For some reason I can't edit from my phone right now. But it was a 5500 ton lift that failed and shot the crane over backwards. A Liebherr (sp?) Lattice crane on a ship. It folded the boom over lile a paperclip.
