I'm looking for some ideas on how people are stabilizing larger suv's or pick-up trucks with large amounts of ground clearance. I've found that the Rescue Jacks don't get small enough, and we can only carry a limited amount of cribbing due to the size of our rescue truck. I've tried building larger step chocks but they still fall short on stock 3/4 and 1 ton american made pick-ups and utility bodies. Any thoughts or ideads would be appreciated.
I've looked into junkyard dogs, they seem to deploy quickly and in a compact design, any experiences with these would be greatly noted thank you
The best way I've found to handle most of these is to build short stacks of box cribbing, then fill the void between the box cribs and the vehicle with step chocks. WIth some practice, this makes for pretty solid stabilization while not requiring that you unload the entire lumberyard from the rig for a single high rise pickup or SUV.
Strut systems are generally too long for the situation you describe, high-lift jacks (farm jacks) don't provide good lateral support, and air bags don't solidly stabilize the vehicle, since they are not solid.
One option for large trucks or 4 x 4 with lift kits installed, is to set your "short" struts in the wheel well or place the strut head on the outer lip of the rear and front fenders.
You can place you strap right around the tire (if it is still intact and touching the ground)and attach it back to the strut base plate.
This location is generally out of the way of the cab and shouldn't interfere too much with your patient removal.
As lutan mentioned earlier, depending on the size and length of your step chocks you can stand them on end interlock them together, take a ratchet strap and wrap it around to keep them from separating.
You will need to be careful inserting them under an unstable truck. if possible use a pike pole to push and move them around to stay out of the collapse zone then insert a wedge to tighten them up.
One draw back is if your doing four point stabilization, you will need a minimum of 8 step chocks
These are just a few options that may work in certain situations.
We use the small set of junkyard dogs, if we have to just box crib then use the step chocks. But I dont ever remember havin a problem cribbing a large vehicle, my department sits inbetween to major highways.
you brought up the Junk yard dogs. They work great we have two pairs of the short and one pair of the long on our rescue. They are adjustable in length and there are numerous ways to use them, Fast and easy to deploy. I would definitely suggest having a sales rep give your company a demo. One of our neighboring rescue companies saw us using them and liked them so much they also purchased them.
We've got a set of Ruts and they work well. During the winter months I'm very likely to respond in my tow truck as I'm often in it when the tones are struck.As long as you can access the vehicle,it's the ultimate way to stabilize.Stabilize,lift,reposition,it's one stop shopping.We've got 4 ' 6' 4x4 on the Engine for those odd jobs where nothing else seems to work.
Using box cribbing made of 6X6 is another idea. We used this in an extrication class. 6X6 box crib on both sides of vehicle with a 8' 6X6 from one box crib to the other, if we had space to the frame still(most likely will) we use wedges to bring the long 6X6 up to the frame. Can use aib bags in place of the wedges.
I have a guy that wants to use Hi-lifts all the time. I don't like them for rescue work in general and basically agree with your comments. Can you provide any more details on when/how they are "good" so I can help convince folks.
Mark Hi-Lift jacks are not a stabilization tool . they are to be used to lift , or pull, or used as a come-a-long, they have many excellent uses, just not stabilization. they give no lateral support. I've even used them to create a purchase point.put them in the window like you would your spreaders ans use in same manner. but again they are not a STABILIZATION tool.
