Teeter Totter

Okay, will it teeter or totter?

Here is one for all of you technical rescue folks.

This was emailed to me and I admit that I don’t know the origins or circumstances.

However, as you can see we have two problems with this scenario: the piece of equipment tilted and the boom in the house.

Let’s for the sake of a good drill say that the reason that the boom did this is because the operator had a medical emergency and is still in the cab. In addition, there are folks in the house trapped.

I know its a lot to think about, but hey, have fun with it. This is not my forte, but the picture was just too good not to use.

Let us know what you would do and how.

Thanks and stay safe.

I used this on everything from wildland to hazmat... I shared the 'CBz' approach so others can use it to stay better organized. I am stoked you find it useful.

Tons of great ideas, as we know many different spokes lead to the center of the hub. The first thing that I notice is that the crane is short jacked, wtf. So i know why it's on it's side and the angle of the boom lets me know where it was when it took off so it is not in any position to come back over. With that said simple cribbing (4x4 or 6x6) will work. This remains true for the tip of the boom, which if it's not on the ground we crib to ensure that if the structure that is supporting it gives it doesn't go but an inch or so. We then extricate as usual. and after emergency care is rendered turn the scene over to LE and the company that operates the crane to figure out that mess. May be get out the BBQ and enjoy a show. Manpower intensive, rescue, engine, medic, ladder and of course the BC is gonna want to see so they will show up.

First and foremost is you must involve someone with alot of knowledge with hoisting cranes. These are fare different machines than most fire folks deal with. I see the boom is close to parallel to the ground and the counter weight is beyond the center point on the aft side (street side). this coupled with the curbside outrigger beams were not extended for the pick make this a particularly unstable unit. Likeliness is that what ever was on the hook is not attached or has allot of slack line judging by the angle of the boom to center pin. This could lead to a up-righting/boom backlash situation if the hydraulics start to bleed off. Also keep in mind that the two outriggers (cylinder rams on the end of the beams) on the ground are somewhat extended and supporting the entire weight of the machine. these are fed by hyd lines that weren't intended to support the whole weight of the machine. then do your ems thing.. life safety first
