...Track on a trailer...

[L999here]

Finally got this APC on the trailer (M172A1). First time ever and request that any heavy-haul truckers chime in to give me some pointers on tie-down and positioning. The track (Brit FV432) weighs about 15-tons (30K lbs.) and the trailer is a military M172A1 25-ton low-boy on 10.00x15TR tires (8 of 'em). Used 3/8ths. chain and heavy-duty spring loaded binders front and rear. Intend to use more chain and binders on the sides for trips. This configuration was to just get to the local gas station for a fill up. Hope the pics come out OK. Comments and critque are welcome....

well first of all you need one chain per tie down point. you can not use one chain for both.. that is a huge FED no no. but you got the crossing of the tie downs correct.

It would be good to go with 4 chains and 4 binders.

BTW, ain't that a nice trailer for hauling tracked vehicles? The width makes it handy!

OK, the way you have the chains, if one device or chain fails the vehicle will be unsecured. The tie downs should be independent of each other. I wouldn't drive around the block with the current arrangement. You need 4 legs MINIMUM and since you are running and tightening a single chain at each end it is considered, legally, a single tie-down. 3/8 TRANSPORT chain, (are you using that?) has a WLL of 6600, you need 4 legs of 7500#.

Good point on the chains Stuart. They might be 43 and even 70 would be insufficient with only 4 of them (in 3/8" anyway).

We used to run chock blocks on the front and back in addition to the chains when I loaded any Tracks on trailers..

In ND where I live the rules are 1 chaine per tie down point AND the chains themselves MUST be transport Grade chains, meaning they are each serial numbered and have a tag on them indicating last inspection date, Pain in the butt YES but if stopped that would be a NO GO in ND!

I have some brand new 1/2 galvanized 10' long chains for tie down for $45 + flat rate box if you decide you want to have some heavy chains.

 

[fstfrdy]

in az anything over 10,000lbs has to have a min. of 4 tiedowns pulling in opposite directions(straight from dot.was stopped at two in the morning for an inspection and was promptly told my load was not properly secured). crossed is best. something that sized i would do 6 at least

Chain rateing

I have some brand new 1/2 galvanized 10' long chains for tie down for $45 + flat rate box if you decide you want to have some heavy chains.

What are the chains rated at? Are they transport chains?

Only bad thing about the M172 trailer is the **** heavy trailer ramps.

See TM 55-2350-224-14 Rev Transportation Data M113 family

You need four tie-downs points min with 4 binders . X crossed front and rear. I would not take that down my drive way.

 

[Burgerboy13]

Also you can never over secure a load. Basically you want as many points of redundancy as possible.

 

[srodocker]

well first thing you should get a m915 or m916 to pull that. or even a m818

nice tank...

also maybe invest in a deuce tanker to follow that thing around to fill it hahaha

oh yea nice trailer + tank

Karl,
LOL, I don't even have everything up on SS because my signature is getting too long. I'm at about 34 vehicles now. Somedays I wonder myself when it will end. Dragonman, I will get you all the specs on the chains when I get home in a week.
