Cribbing Questions

There is an operating procedure for a side lift, (single side access) or the clam shell manuever to free a person from beneath. Strut attaches to the roof line in the area of the B post, (center) and attach the stabilization straps to the opposite undercarriage, crank and lift like a kickstand.

Like I said regardless of manufacturer, it can be done fairly easily.

This set-up is so quick most companies are still working on opening up the regulator case, color coding the hoses to regulators to bags, and the crates of cribbing being moved while the above system is "lifting" after chocking the wheels and securing just two hooks/straps.

I don't like the purchase point shown - the window frame isn't generally a strong point, particularly on unibody (beer can) cars. I can bend a lot of those window frames with my arms, and I'm not anywhere close to Superman. If I can bend it, the weight of the car hanging from a 2-inch square strut tip can bend it or tear it. If you lose that single, tightly-focused purchase point, then the car comes crashing back down on the patient.

Further, if you have a patient trapped in the car and another patient trapped beneath it, you have a much bigger potential to pendulum the car with the strut than with the air bags. That pendulum motion isn't good for the interior patient's c-spine.

The cribbing point is a tie between the two systems - if you're cribbing as you lift, it takes time to get the cribbing out either way.

With a preconnected air source, it takes a grand total of four quick connects...snap, snap, snap, snap, stack two bags, and start the lift. That can be done before the rescuer on the back side of the car can fish the strap out from beneath the lift and ensure that the strap doesn't impinge on the patient.

I still question strut lifts as maybe being OK for the car but not necessarily good - or safe - for the patient.

Dual kick stands don't fill the void as you lift. Any time you don't physically fill the void beneath the lift with cribbing, you're risking a catastrophic failure if anything goes wrong...like a tensioned strap getting cut by debris, a chain sling slipping on slick metal, or a damaged unibody folding into a clam shell.
