Box Cribbing

[remya]

Does anyone have a photo (cribbing for dummies) or instructions on how to make the box cribbing sets (the ones that come out as one unit and pull apart to make the crib) that Mississauga (and most likely others) uses.


Thanks in advance.

[LtBlondie]

are you talking about "step" cribbing? this is made up ahead of time, we keep one set on every vehicle they slide right under the vehicle quite easily. The box cribs have to be made as you go.

[remya]

Thanks for the reply LtBlondie,

I think what I saw may be used for extrication competitions only. It was defiantly a number (6 or 8) of 4x4's that made up a quick box crib when released. I had seen it on the discovery channel a few months back and it was Mississauga Fires extrication team. I know I'm not describing it to well.

I think what you are looking for (please correct me if I am wrong),
is cribbing that forms a series of steps or boxes.
looks like this maybe??

You get the idea. The wood is (at our house) 2x8 with the top step 6 inches long and the bottom board about 24 inches long.
Each board is fasatened togther forming aseries of steps. We have 4 steps on each one (4 boards).

Are we on the same track?

[Red_Devil]

Kirk you are not on the same track, what you have drawn (if you wanna call it that lol) is step cribbing, What Remya is looking for is box cribbing that the squads carry. I too saw them on the discovery channel, Basically with the pull of a rope or release of a pin the 4x4's arrange into a simple box crib instead of having to build a box with single 4x4's. Basically a box crib is 2 4x4's that run parallel, then you stack another 2 4x4's on top but these 2 run perpendicular to the bottom 2.

Mark me down for 2hrs of auto ex training!

[Kirk]

Hey Red Devil

I C...
I failed art class, does it show?

It sounds like the 4x4's are fastened togther as a unit? So that they "unfold" to be a box..
I see the light.

[remya]

Thank you Red_Devil. Sorry for the lame description... yours is much better. At least one person has seen the same thing I feel better now. So wish I could find a picture.

[wilderness]

Yea discovery channel had something on that one day, maybe e/mail them and ask them about it

IAMVFF, yes that is box cribbing lol, remya knows that, you didnt have to get your copy of essentials out to show us all that lol, what hes looking for is something where you dont have to stack the 4x4's to form the box, the 4x4s are all pre connected

Well R_D,(LOL),
I will start by saying that even though this may not be what he wanted(LOL), at least it was an effort to help(LOL). Where is your effort to assist in the posting(LOL), or any other post on this site(LOL). I think that I have been to enough MVA's and taken enough extrication courses that I am aware that these are basic diagrams of box cribbing(LOL), I have never heard of foldable ones, and I guess that I never put 2+2 together to realize that someone would be that freakin lazy that they can't stack a couple of 4x4's on top of each other(LOL). Especially concidering that you never have a standard width or height required.(LOL) Not to mention that maybe you need 4x4's, maybe 2x4's, maybe you need wedges. I am not saying that what you describe is not available, it probably is(LOL). They can make anything and someone will buy it(LOL). Maybe if you put forth the same amount of effort in helping as you do in insulting, we could have ended this topic on the second post(LOL). I will look forward to your solution on this topic, but, you know, don't strain yourself, thanks for the help in advance....buddy(LOL)

Have a great day(LOL)
BE SAFE(LOL)

Guys no need to get out of shape. Thanks for the effort iamvff...it is nice to see someone take the time to try and help a person that they do not know. (good trait for a Firefighter). I know my description sucked, I really hoped that I would get lucky and someone from Mississauga fire would see my post and send me the basic instructions on its construction (I'm sure it is pretty basic but I would rather use a tried and proven design then me playing around the wood shop for a month). I don't think that the system would produce laziness but the system I saw would let one firefighter carry two or more sets making two + box cribs (4x4's) instead of fumbling down to the vehicle with enough wood for 1 and a half cribs and the rest laying on the road way between the rescue and the intended target (vehicle).

When we only have 5-6 ff's on scene it would be nice not to have to use everyone as a lumber truck to stabilize a vehicle. When I find a picture I will post it and you will see how slick it works (if I find one).

Thanks again Happy New Year and stay safe

"Remya"
From what i understand, and i have been proven wrong in the past. the rapid deployment of cribbing that you are looking for. is just small set of cribbing made up and then instead of 6 seperate peices being pulled. its six pieces preformed into one piece. so this makes it faster to deploy.... and it takes up less room in the vehicle..... when stored

[remya]

Wilderness, you are on the right track but I think I neglected describing a major component. Here is what I hope is a better description.

Close your eyes :)

-Imagine 6 4x4’s lined up together side by side, flat (all the same length) (now here is where I have to theorize as to the method used to keep these pieces together)
-All 6 pieces are attached somehow (maybe as Red Devil suggested with a pin) through each piece.
- When the pin is pulled out every second piece stays attached. (So now you have 2 sets of 3 pieces attached)
- Now all you do is turn the one set 90 degrees to the other and you have the beginnings of a box crib.
- Benefits, 1 FF can carry several sets on there own and as Wilderness mentioned the space on the truck would be more organized and less space used.

[wilderness]

yea thats it but i believe they use commercial cargo straps as webbing to hold the peices together....:rolleyes:

[firedan76]

You will need, 6- 4*4's (rough hardwood), 4 old peices hose, drill, bits, and rebar/treaded rod/or rope. This job has a 2 beer difficulty level. (off duty of course)


- Take 6- 4*4, 18-24 inches long.

- Line up the 4*4's tightly side by side.

- Use old fire hose, or cargo strapping and attach perpendicularly (across) to ever other 4*4 (thats 3 per side) with screw and washer.

- Use 2 straps per side and attach them approx. 4-6 inch from ends.

- Flip the 6- 4*4's and attach the other (opposite) 3- 4*4's in the same method.

-Thats 2 straps per side and attach 4-6 inch from ends.

-Now drill a 1/2 inch hole through the assembly in line with the hoses/strapping.


Now you have 3- 4*4's straped together that cradle 3-4*4's straped together with a 1/2 inch hole running through each end in line with the strapping.

-To fix the assemply in the cradled position you can use threaded rod with wing nuts. (better buy spare wing nuts, you'll lose these at every incident

-Or take re- bar, bent in a squares u shape to fit through, bunge tension on the top will keep in in place (not through off roading)

- Or use 1/2 rope (might need bigger hole) with beaner or quick release knot.

They do not have to be fastened, if you just want rapid cribbing or neat cribbing storage on your rescue. Having a fastening system is just for ease of transport (i.e. off road, industral ,and heavy/collapse extricrations)

To me it seems we need less cribbing for day to day extrications, (lots of cars, most of them low) but every now and then theres a holly sh*t rollover or embankment job where you need everything in the cabinet.

Hope it helps!!;)

[iamvff]

OK, I'll eat crow, here, and take back my comment of being to freakin lazy to stack 4x4's. (but R_D still pissed me off with that post) I now can visualize what you guys are saying about the cribbing and can definately see an advantage to what you are describing. Thanks guys for helping remya out, I see the light now (although it's still not a green light ) :D

Although I must admit that this description sound very labor intensive.......I'm thinkin about 4 beers!

Be safe,
iamvff

[wilderness]

maybe we would be using the cribbing in the picture where all the beer bottles were on the road....lol we could only hope

[LtBlondie]

I agree with imauff.
When I'm doing my size up the crew can get the vehicle "boxed" in no time so when I ask for the cutters or rams, air bags or whatever the stabiliztion has been done quickly and they are free for the next assignment.
Just a thought.

[remya]

First off I would like to say thanks to everyone for helping with this. I too would have to say that I think two beer is far to little for this endeavor, looks more like a 4-5 beer.

firedan76 - Thanks for writing all of that down. If this is the same one that was on discovery channel. I do not recall it having so many parts...who knows I had only seen it for a second or so and had only one eye open.

iamvff / LtBlondie - I thought that I saw something a little less intense then firedan76 has described and that it would be a real time saver on scene. I must have been mistaken. If I ever see what I thought I saw you will see that it is slick.

Thanks again

[firedan76]

Ok, ok.. you are all right about the number of beer on the difficulty level.

I saw the same discovery show..i think it was "fear fighters" it had to do with auto x technology. I taped the show for training and rebuilt my self the cribbing. It's likely my winded explination that made this sound difficult, but it is not!

This is a very good system and it is very fast..one person can carry and deploy 16 vertical inches on a solid base of 2*2...perfect for ground to hood jobs. (thats one in each hand, guys with bear mitts can carry 4, 32 vert. inches) To deploy just lay it down, pull the rod (I used re-bar) and stack...works great

[Toxic]

Firedan: Could you post a couple of pics of what you assembled? Might help to clarify it a little four those of us who are visual types.

[Red_Devil]

I seen it used at teh auto extrication competitions, if you attend on of these you maybe able to ask them about it, mississauga is usually at one in ontario at some point, hey did ya know they are teh world champs

[Rescue78]

WOOOOOO!!!

I've competed against Missisauga. They are a great team and they have all my respect. But world champions ?????

Mississauga won the Canadian National Vehicle Rescue Challenge 2004 in Wasaga Beach. It is a national event held by TERC Canada. That makes them National champions.

Things have changed a bit with TERC. No longer do you win your regional and head to the International. Terc USA holds THEIR National, TERC Canada holds ours. Teams from the Nationals qualify for the International.

Mississauga qualified for the 2005 International Extrication Competition in Fort Lauderdale. I wish them best of luck, but untill next year, Don Valley, South Yorkshire, England are the World champions (not that I like it but).

Maybe next year, but not quite yet.

That beeing said, I think Mississauga certainly is a leader in the Auto X world.

[Red_Devil]

sorry your correct, they are the national champs

[wilderness]

who are you and what have you done to red devil.....

[Red_Devil]

hey wild, the ole devil isnt an assho le all the time!

[wilderness]

i never said that.... its just funny seeing you admit your wrong full timer.....lmao....

[firedan76]

"Homemade" rapid cribbing photos to come...

For a similar idea, in a commercially made product...see

www.res-q-jack.com

With all due respect to res-q-jack, this product could be easily made in house as well.

[Roadwarrior]

Firedan76 has it quite well described. I saw at least 1 team using it at the TERC competion last weekend in Port Hope. Very compact and readily deployable. Awesome competition....lots of rookie teams as well as the veterans. Got to give them full marks for their efforts.
