Crane collapse

Big thumbs up for sticking with the shot and keeping it steady. Well done sir!

I second that and didnt even talk all over it also

[@kingjames8283]

This is just one of the jobs I perform for a living and what happened here was sad because it was a fixable situation. Thankfully no one got hurt in this one. Hanging pre-stressed concrete wall panels is best done with a lattice-boom crawler crane, not these mobile jobs with outriggers and this is the reason why.

[@ToTheTopCrane]

I set precast with a 200t mobile hydro. The difference......I make sure my outriggers are on material that is sufficient to carry the load.

[@kingjames8283]

@@ToTheTopCrane - All of our jobsites are soil stabilized before we arrive to ensure it can handle the weight of the trucks which approach 95,000# each and the crane. We use both hydraulic and lattice boom crawler cranes. When setup properly, both crane types are equally capable. Only downside to hydraulic cranes is the excessive time it takes to move crane along as panels are put in place. Therefore my preference for getting a job done fast are the lattice-boom crawlers as they are only assembled at the beginning and disassembled in the end, and are free to move readily in between. Not only that, but they can fit in tight places and function in ways hydraulic cranes cannot such as traveling with load. I'm not afraid of hydraulic cranes as I work with some of the best companies and crews. In twenty-five plus years, we've only lost one brand new zero hour Manitowoc 999 to operator error. That is the most used crawler crane used in my area.

[@ToTheTopCrane]

@@kingjames8283, I definitely agree on the on site mobility aspect of a crawler. They unequivocally win in that regard. When I set up a hydro for a precast job, I have to maximize the working radius. Which makes for a max pick at each end of the run. But, it's definitely doable. Just takes a little forethought and pre planning. 🙂

Good shot and thank you for not title bating a fake video and it was more than I expected. You know how people are today. This was the steadiest video I’ve ever seen of a crane collapse.

[@kaburgess69]

Once the ground gave out and the outrigger sank, the superstructure would have no choice but to swing to the left. The counterweight would just follow gravity to the downhill side of the crane and the slew brake isn't strong enough to hold all of that weight back. I agree that he shouldn't have tried to hero his way out of a bad situation, once it stopped moving, just get out and wait for the calvary to show up with the other crane needed to lift the back corner out of the hole.

[@ToTheTopCrane]

Dog it off and wait for assistance. It's bad enough to get in the situation to begin with. But, it's much worse to pile it up because of a lack of patience. Hopefully no one was injured or killed.

Yeah, looks like they could have boomed down some to try and help.

[@MeetWilliamVaughn]

I am a crane operator (30yrs) and currently doing tilt-wall panels just like this. The operator count boom away because he was facing the wrong way. If you look close you will see the gantry leaning against the wall. If he would have rotated he would have gone over. He should have waited for another crane. I assume he was trying to lift a wall panel that maybe fell on his crane. Sideloaded the boom and it folded like a cheap suit

[@haughie61]

@@MeetWilliamVaughn shudda got someone to watch gantry and boomed re down

[@j7c4n]

Once he unloaded those pennant lines on the back of the boom it was all over. When you're in trouble like that it's always best to let out rope and boom down to get her as stable as you can or at least prevent it from getting worse. Tiltwalls are not for the faint of heart, you're at max chart or outside of chart at sometime on nearly every job.

I'm an Iron Worker. It looks like the outrigger on the front right sunk in the ground or some ground collapse of a hole on the job site where the downrigger was close to. The crane is picking up pre-cast wall panels. The panels weigh @6tons, not very heavy for the crane their using.

[@1432bird]

This opinion from a crane operator. Looks like outrigger failure of some type, ie ground, pad, or mechanical what he should have done was disconnect the rigging, boom down to get weight on left outrigger and minimize the tipping to the right and swing to the right to get the counterweights over the center of the crane but for some dumb reason he tried put weight on the load line and pulled the boom sideways and backwards, just a real panicked dumb ass move.

[@blacknwhitetruthfully5325]

Jeff Osborne I agree

[@rayschmidt3388]

The ground was soft , and they should of had crane mats, or one inch thick trench plates delivered to place under the rear outriggers. The operator never should have swung the counter weights over the low side. With the boom at that high of an angle , swinging the rig in the direction that he did only made this mishap much worse. If he had swung the rig the other way it would have put all the weight over to the high side, and helped settle it back down. I do have a little bit of experience in the area of crane operating, being a instructor at a heavy equipment training center, and a certified practical examiner.

[@dylanpeterson6192]

I was thinking the same thing, but it looks like the direction he slewed was the way he came from when he set it up. I dont think there was anywhere to lay the boom down except over the front or left side of the video.He may have (ironically) been worried that swinging the weights over the high side would make things worse on the low side? Who knows. Tilt up always looks sketchy to me.

[@ditherdather]

So much for releasing cable tension.

[@hvyopratr]

One thing for sure the operator did not understand the difference between a mast and a gantry it could have worked with a gantry possibly but definitely not with a mast at that angle. All he did was tension up on the load causing the boom to roll through the load line and pull over backwards, typical mistake people who have not run a mast style crane. Boomed up way too tight for that. Should have boomed down before he started tensioning the line Assume he was trying to get the mast off the panel behind him Who knows . I ran a lot of tilt up , it's a cowboy industry I'm sure he was thinking he was doing the right thing to save it, Easy to Monday morning quarterback not so much when you're there.

[@MrTysteel]

Looks to me that he was rigged up picking the slab and when he started stacking the weight the corner of the concrete slab he's on gave way into the footing, when he took the load off his swing break wouldn't hold the counter weights from swinging into the wall, not enough swing power to push the weights up hill so he tried to rig up to the back of the crane to use the hoist to pull it around but instead it pulled the boom past the point of no return. Should have waited for help!

[@torchandregdoc]

I think you're close, but I think he's trying to pull the boom down, not trying to pull the super back around, which in theory was the right thing to do. He was trying to boom down but the fleeting shieve was punched against the panel and the mast. He was so close to saving this. However, if he would have gotten back and taken a look, he would have seen that because the rig was already laying back so far, hooking on to the carrier was just going to pull it over backwards. It's a shame he didn't pull off of some thing in the building, ie a forklift zoom boom, or and unstood panel. He just needed a few thousand pounds to get it going. May have needed to chain off the swing as well because as soon as it would pull the mast off the panel, it was always going to keep coming around. It's like standing a rolled over truck on a hillside. They always go to the bottom if you haven't set the brakes. Like everyone says, He should have waited for help. Risk to Reward.

Ouch. I was in a very similar situation before and had one go in. Technically this is not a collapse but a roll over --- loss of stability --- resulting in the boom buckling. Could have been caused by insufficient outrigger deployment on that back corner. More likely though the ground is backfill and not capable of supporting the weight. Had close to the same happen due to ground softening from water run off.
