@ai6yr The article briefly mentions they built a field rig to lift/shift the boulder. As someone interested in engineering, I'd be curious. The photo suggests that maybe they wrapped it in a webbing, then pulled it off of him, perhaps with a winch.

That's the kind of object where if the other end of the winch is something like one of those fire trucks, you might drag the truck along the gravel more than move the boulder, even with the parking brake set on every wheel.

They've got better photos and videos at https://www.facebook.com/clackamasfire/posts/pfbid02RxUmxLowEdg2hoVNWWrKtz9Mr5XxtgecEgJuFsHkdLSZbdZgNNGxumhTP3KgZNHnl

Looks like they squeezed in one wooden wedge at a time until they could get the patient out from under it. So just winching an inch at a time, and making sure it couldn't drop back down to the starting position.

@me_valentijn @scottmiller42 @ai6yr It's more than just lifting the weight without risk of it falling back down...as the weight is removed, you have to be looking out for bleeding. With crush injuries the weight is often all that's keeping the blood on the inside.

I know several of you are pros at this; I only had one day-long course in lifting heavy objects off of trapped people, focusing on tilt-up construction, not boulders. I'm open to corrections!

My one day was a disaster also...group of four trainees. When I was getting my turns with the dummy under the slabs, the other three were supposed to be managing the lifting and cribbing, and they weren't. So I was yelling orders at them while trying to pass the class while also trying to avoid being crushed by these morons as they repeatedly dropped the slab.

Teamwork is a lot of fun, really.
