CHOCK those tires!!

[tigger]

for a 5t I would use at least a 6"x 6", a 8"x"8 or bigger would be better to make wedge ckock blocks

Small cars work good too!

OTHER things work just as well for 5ts but my kinder/gentler self has to reframe so as not to hurt feelings,

M 816 chocks

Can someone please give me dimensions of the proper 5 ton chocks - I have pics of wooden ones, but didn't take dimensions. Or pics and dims of the steel ones... Including the chains too.

Unless someone has them for sale in the North East.


Thanks in advance.

The yellow wood one is 14 inches long, 5.5 inches wide, and 3.5 inches tall. The rope is about 3 ft long (3/4 inch dia.)

Hope this helps

5 ton chocks

Thanks Mike, but I don't think the "F-16 chocks" you posted earlier are big enough for a 36,000 lb wrecker (+ any vehicle it has on tow). Some one else posted that their 5 ton rolled right over some low chocks.

I am looking for the correct, BII (though they are not in the TM posted on SS) chocks that were issued wit hthe truck, in Olive drab, with painted on MSN #. The ones I saw, and got camera pics of, were at least 6" high, with a long chain that goes up to the bed side.

I have homemade ones that work, not a military pattern though, but I would like the correct ones.

Thanks again.

The black rubber ones will stop your wrecker, as they will stop a 747 from rolling. The Swiss Army used them on my Unimog, and it can get over one with a lot of low gear power applied, but no other way. Central Tractor has them for reasonable.....

Is this what you want?

I like that but you need to start with and copy an existing chock

I think I have one somewhere. I'll look this afternoon.

I bought some of these ones for my M925A1. I wanted some that were tall enough, so I searched for quite a while til I found these nice tall ones. I chained them together with a 50 inch chain which made them just the right distance from eachother to go in front of and behind one of the wheels. I keep them in the tool box on the right side.

Wow, it is an F-16 Chock, and yes an F-16 can jump the chocks as well as any of these trucks, but it should hold against gravity assuming you are not pointed down a serious hill side. I also see old "F-16" chocks used all the time for trucks albeit none as pretty as my shinny new one. (but understand if you want something bigger as well.)

Note that the rubber ones that are hollow are less safe. I have seen Semi trailers fold them over on a hot day, and if the driver rolls over them they will be crushed.

The hollow rubber ones are also much heavier then the wood ones. I would suggest scaling up the wood one to what ever size makes you feel comfortable.

Oh so many chocks.

Jeff - "KsM715" Thanks for the "Marvel" comic pics - yes, that is the thing I am looking for. So, if you find one - or anyone else finds one, I'd love the dims of the pieces parts or the whole thing, inc chain....

Looks like it is a 6x2 laminated sandwich - and of course 6x2 is not actually 2" but ex 2" so more like 1 3/4".....
Base length is probably in the order of 10".....??

I think the bolts are 1/4", not suer but that should do since there are a few of them.


Thanks you everyone for your assistance.... I really enjoy the communial knowledge sharing that this site provides.

OK,I think my wooden chock went with the bobbed deuce when I sold it. (I prefer the rubber ones, I think I remember throwing it in when he bought it.) Anyways, I have 2 styles of the rubber ones. Both roughly the same size but there is a small difference between them. One has less of an angle to it but has a tall step at the top making it fit the tire alittle better. I don't have a chock holder on any trailer or truck I have here but I remeber seeing the triangle shaped rubber chocks in the holders on trucks and trailers on the GL lot.

The first chock is: 9" long
with approx. 62-63 degree slope
8" from side to side
and About 6.5" from bottom corner to the top corner
and a 2" width at the top

The other chock is dimensionaly the same but the slope is about 50-55 degree with the top about an 1" to 1.5" straight up

Just throw a PVT. under it!

As another alternative for chocks, I make mine out of treated 6X6's. I cut an 8' in half to make it easier to handle. I then set the blade on my 10" table saw at 45 degrees and set the fence 1" from the blade. (blade tilted AWAY from the fence) Then I run the 4' pieces through, and flip them to cut off a corner. Now a 10" saw will not cut all the way through so you can finish the cut with a hand saw or sawzall. I "pretty" up my chocks by running them over a jointer and sanding, but that's optional. Then you can cut them to what ever width you need them. You can attach chains or drill holes and glue rope in for pairs if you want. I paint mine with paint that has sand added for grip. Just another way to do it. You can get up to six pairs of chocks out of one 6X6 if you cut them just under 8" wide. Generally it will cost around $15 for the wood, extra for paint, rope or chain, very cheap but works great.

Is this what you want?

Actually this is the correct chock UNTILL the 1400s came out on the 939 A1 and A2 series trucks, The correct chock in service for that series truck and larger is an oak chock, that looks almost exactly like the f 16 chock and close to size, PM me if anyone wants the exact correct measurements, I have a few to measure for U, But the fast difference between the F16 chock is No rope, no cut out for rope, just an I hook screwed into the center of one end, then the mil style cheap chain, with a dog leash looking end that hooks to the side of bed loop, chain is about 6ft, just like the older style crane truck pictured... """ >>> BUT I will add the chocks dont come with the chain for the 939 series with the 1400 tires, just the chock, so U will not see the chain on most in service...But both with and with out chain would be mil correct,

I use these on my 5 ton I haul water with I have to back down to the water and place the chocks behind the trailer tires when loaded I drive up till a level spot an walk back to get the chocks . I have used the rubber chocks they seam to mash down from a loaded truck or trailer some times they tip over a wide base works best .

 

[123mack]

measurements for the wood chock on PS magazine:
width- 8.5 inches
length along ground side: 10.5 inches
length along tire contact side: 8 inches
bolts: 5/16" dia
bevel ground contact edges a per dwg in PS mag. This helps prevent the edge fron breaking off.
These measurements are nominal, as the wood has shrunk since maufacturing.

The way he is walking funny suggests he is on his way to change his shorts.

I chock my five tons everytime I park them. I also try to always park on as level a spot as I can and turn the wheels into a hill or curb. Chocks really don't mean much to a five ton or the newer (00's witht he 1400's. they are just too big for such a small bump. I almost always forget to pick them up when I start up. When you roll over them you can't even feel it. I left chock all over the state by now so everybody should have at least one. Park on a level place,trans in neutral and turn your wheels into the curb.and chock the wheels Always. If You can get the same big chocks Randy has get them too.
