Booming Down a Tractor-Working Load Limit

Booming Down a Tractor-Working Load Limit

Hey, this is Mike with Several viewers have wanted me to do a video on how to properly secure a
tractor to a trailer if you’re gonna move your tractor around. It’s taken me
awhile to get the information together to do this I wanted to give you good
information I’ve studied up on the regulations I met with Missouri
Department of Transportation officials, spent a day with them and there’s a lot
of information to share and I apologize for doing this to you but I’m gonna
break it down into four videos and if you’re going to move your tractor on the
open road on a trailer, I urge to watch all four of them and the first one is going
to talk about the way you select the chains and binders to secure the tractor
to the trailer because there are some mathematics you must do in order to get
the adequate amount of pull on the chains and the binders. We’re going to talk about chains and binders today but those are just two components of securing a
tractor to a trailer that you need to know about and, stay with me guys, this
is kind of dry information but at the end of the video I’m going to tell you about the third component that most people don’t even know about. First off let’s talk
about chains. You’re securing a tractor to a trailer you’re gonna get chains
and you need to get at least grade 70 or above chain and its marked on the hook
this is G70 right here which means grade 70. Now I want to put a little
plug in for Lowes, I don’t get paid by Lowes but I found this chain, it was a twenty foot
5/16″ chain at Lowes for 37 bucks which is pretty cheap for a heavy chain so that’s what I got. Now on the chain package, I’m just going to pull the label off and I ripped it. Here it shows the
rated capacity of the chain at 4,700 pounds that’s the WLL or working load limit of the chain, that’s the maximum it can hold- 4,700 pounds remember that number. Now the second component in securing a tractor to a trailer is a “boomer” and here’s a boomer this is a ratchet style boomer. Most boomers will say on the handle and I’ve
got it upside down right here, the working load limit of the boomer and
this has a WLL of 5,400 pounds now you take the the lesser of the two so in
other words the binder, or the boomer, can secure more than the chain. Alright, the third component is the place you attach it on the trailer and we’re either
looking at a a rub rail like this one has or a d-ring which is a specially
designed bracket just for securing equipment to a trailer or in my case I
went through a bracket that is designed to hold stakes if you put sides on the
trailer it’s also designed to to secure tractors or equipment to the trailer. Now
that will have a WLL or working load limit rating as well and most people
don’t know that, most trailer people don’t know that, the people that sell them,
I’ve sold trailers and I didn’t know that but that has a limit. Now here’s how you calculate your
working load limit and whether you’ve got enough chain and binder rating and
trailer rating to secure your tractor let’s say our trailer securing point was
rated at six thousand pounds, our boomer or binder at 5,400 pounds
and our chains at 4,700 pounds. You take the lesser of those three numbers which is
the chain, at 4,700 pounds. And we’re gonna put four chains on the load so we’re going
to multiply 4700 by four which gives us 18,800 pounds now we divide that number by two
which gives us 9,400 pounds as long as our load weighs less than that we’re
within compliance. This is a little complicated it’s a little long and dry I
appreciate you staying with me. Hey I survive on web traffic if you’d
like to share this video with other folks that would be awesome I’d be
honored if you subscribe to my YouTube channel and also have a Facebook page it
would be awesome if you’d like it thanks for watching

  • Chain limit is straight line pull the angle reduces the load limit. For example when tying down cargo in the marines a 10k chain and binder was calculated at 7k

  • Nice video but you should have clarified why you divided it by two, I'm sure most would assume two front & two on the back but specifics are important.

  • That is a new one Mike. I have NEVER heard of a load binder being called a BOOMER before. Down under when i started driving trucks 40 years ago we simply called them "dogs" & still do.

    Looking forward to the rest of the series.

  • @ 2:53 you are mentioning the trailer attaching or anchoring point has a WLL but you didn't mention how it was determined. Was there a plate or documentation with your unit? Did the manufacturer have something? If it isn't documented somewhere, you would be taking a risk and shouldn't use that trailer for hauling the tractor.

    @ 3:55 you were discussing the reason for dividing by 2. The recommendation is that the total WLL of all the tie-downs used must equal HALF of the cargo's weight. (This is like another safety factor on TOP of the other safety factors.)

    For example, if the tractor was 20, 000 lbs, then the combined WLL of the 4 tie-downs must meet or exceed 20,000 / 2 = 10,000 lbs. The WLL for each tie down should meet or exceed 10,000 / 4 = 2,500 lbs, in this example.

    (Here is another separate confusing note that might be covered later: Depending upon how you connect to the cargo (direct vs. indirect), the method could also reduce the WLL of the tie-down. Direct connections reduce the WLL by half, whereas indirect tie-downs do not reduce the WLL. )

  • Tractors under 10K that are privately hauled may not be subject to any regulation in your state. I recently picked up a tractor 3 states away and in my case it was pretty much up to me how I secured it baring some outright inadequacy like duct taping it down. I'm sure, if it came off the trailer, there would be some post catastrophe attachment of civil and/or criminal penalty. To be responsible, I "youtubed" various state police videos and probably over engineered the tie down process but it would have met any DOT standards for the tractor AND the implements that were attached. Mike your video came out about a week too late for me. Surprising the dealer said it wouldn't come off if I just put a strap over the loader bucket and ran some chains to the draw bar. It probably wouldn't have but if it did, It's my fault not theirs so I tied it down to meet commercial standards for a load greater than 10K.  Using this standard will keep you safe and legal pretty much everywhere. I'm still going to watch Mike's following 3 videos on the subject as soon as they are posted.  There's no reason for me to stop learning.

  • Instead of multiplying by four then dividing by two it's a lot simpler to just multiply by two and finish there.

    Aside from the math being equal it also makes logical sense given that you have two chains sharing the load on each side to just multiple by two.

  • Good video and I hear boomer and binder here. Is the WLL of the trailer marked? How do you know what it is? Thanks

  • Hi Mike,I have a question for you. I have a 1944 ford 9N farm tractor,and I would like to install a front bucket on it. Can you or do you have a video on how to install on a older tractor? Thank you,Buddyboy

  • Hey Mike, this video is all about chains. Are tow straps an acceptable alternate (as long as they meet the load requirements)?

  • I may be wrong here, but i'm assuming this formula is set up so that any 2 chains will hold the load…tongue side when accelerating, ramp side when stopping and sides for turns. If you're using various chains and boomers then the 2 on any side should be able to hold the load in order to be safe.

  • How much does the tractor weigh? You never said.

    Omg, please turn that snap-binder around and pull on the binder pipe. I cringed witching that.

    What does MODOT mandate for a legal tie-down? I've aways gone with 80%. 80% tie down. I think it's 70% of the load weight restricting the load from moving forward, 20% restricting the load from moving backward and 50% of the load weight restricting the load from moving side to side.

    I just looked it up in the Federal Motor Carrier Safety Regulations.

    FMCSA regulation 393.102(a)

    80% deceleration in the forward direction
    50% rearward or side to side

  • The example you used in the video calculates the max load limit as 9,400 lbs, but the trailer max load is 6,000 lbs. I take it you don't go beyond whatever the trailer load limit is?

  • If you're using a cam buckle type binder and a ratcheting binder on the same load, tighten your cam buckle binder first then tighten the ratcheting binder up. You can get your old tighter and don't have to fight so hard trying to pull on a piece of pipe to get it tight.

  • Not trying to tell you what to do but give you a little advice, turn that snap binder around much safer trust me. In your change when you look them through the whole they only had two points of contact you have to have three points of contact.

  • Your helper binding down the old style binder is lucky his hand didn't slip off that cheater pipe and crack his skull and kill.him for his stupidity and trying to push instead of pulling down the binder and you didn't correct it in your video…wow… incredible and btw his had didn't slip but the binder went sideways on him ….

  • If you all want real sound flat bed and heavy hauling loading info, go to California's DOT. regulations. if you meet their standards, you are good in all states. been their done that! And Mike, you keep binding down like that snap binder, your videos days are going to be shortened!
