Crane accident 8/31/21 Washington State

I watched it a couple of times at 0.25X speed. Neither camera angle is very good for seeing how it falls and loads. I'm unsure if it hung on the cable, but it's awkward geometry since it initially falls towards the cable and then has to rotate away from the cable as the swing is completed and it loads the cable. I see it coming to rest butt end up. It seems like the rotation, then counter rotation could make peak force higher than for a simple swing.
It took me several tries too, but then I realized that if it were tip down, there would be a lot more sling showing between ball and butt. But after watching it make it to ground, it's definitely butt down. Even better, on the fall the tips raked across the ball and the ring sling he had girthed on the ball for his TIP. Raked across violent enough to leave a chunk of brush behind. Wow.

So for conversation sake ONLY. The top should have been taken lower, (yes heavier).
faced to the boom, with a butt tie holdback.
But it should never have been done.

the thing about Doug fir tops is they are fairly light but long. A 20’ top can be about 4-6” at the butt.

as I said before if they are good to 6k (and we don’t know if this is WILL or SWL) the top should have been rigged from itself and the crane pick it from the spar. Plenty of room to zip some limbs (small top limbs) or just take some brush pick bundles

I'll just say this then shut up. If they had swung everything pendulum from horizontal to bottom, the swing would have only tripled the effective load seen because it's being absorbed into a long swing. So yes they could have picked it after cutting and swung it onto crane for only 3x the load absolute max. But, the short negative rigging scenario from a hung up top that is going to instantly shock load into a short piece of cordage could have been the real issue.

You're right. I hadn't rewatched it coming to the ground butt down. Sure does a lot of gyrating though.

Maybe next, for our viewing pleasure, they can set the crane so far away, the operator has to cable up during the swing to keep the top from hitting the ground.

Not quite likely, the top would have hung up in the canopy below breaking it's fall (and possibly limbs), the traditional lowering line could then be knotted and picked with the crane.

Also not saying my way is the right way just throwing out alternatives that are a little less stupid than what they did..

Why not just go for the easy solution, and take a larger pick? It is possible, if the operator of the crane is halfway decent, to take a piece that is higher than the boom tip. It simply has to be weighted low enough that it will stand upright, and the crane operator has to be able to keep it from getting tangled in the Pat line. With 6000 pounds of capacity, I would expect that such a cut should have been possible.

Agreed, but we don’t know if the 6k is will or SWL. But if possible HELL YES totally do able
 
Got to love the fact that after the initial bullshit we have turned this into a meaningful conversation about alternatives to shock loading a crane....
There’s always a kernel floating around in the septic tank, and the brave might even find a wedding band stuck to the scum on the bottom
 
The fun starts right around the 20:00 mark. Winch line sucked into the chipper, subpar cuts, pinched saws, climber hitting himself in the head with a midsize saw, the wedge clown show, etc....

Please turn off the cameras....

This amateur hour, reality tv, clown show has nearly twice the subscribers as Reg and August combined. After watching a few treeson/Eastside vids this morning all I could do was shake my head and pray that young climbers out there are not taking Team Treeson too seriously. For Realz.

Rule #3. If rules #1 and #2 are disregarded make bloody well sure you don’t get bit by the potentially deadly snake that is crawling in the brush.

This is the new norm, bunch of yappin followed by some sloppy work. Looks like beginner work. Boom up, cable up ahh whats the difference throw me up a wedge my saw is stuck again. I agree 95% of these dudes need to put the camera away. The otherday, on another thread, I was accused of disempowering, whom I am not clear, when I said "most customers, climbers and tree companies dont know what bad work or unqualified looks like."This speaks to your comment of why these guys have twice the subscribers as Reg and August.
