Two D11's Have a Tug of War!! 

The safety factor on lifting straps is impressive, and when they do break it's a lot safer than having a chain or cable let go. I've seen chain links almost completely straighten and fly over 100 metres, and that was just with an old 935 Versatile pulling trees, God only knows what two D11's would do to a chain :P

The cost of owning TWO D11 dozers alone makes this video impressive

Last time I've seen that much tension it was thnaksgiving with the family.

I’m from America and this video makes me love Australia more than I already did! Badass mate!

I've never seen a sling fail that way. Once a strand or two broke, it was wild to see how the rest took off. Nice science experiment, Matt and your Mastermind assistant. 🙂

In slow video playback mode, it can be seen that the belts were broken at the point of contact with the metal canine. That is, the straps simply cut themselves on the harder material of the canine. If you make a semicircular spacer from wood, it is possible that three belts would withstand the traction force. In any case, it can be seen that the straps are very strong.

I was a recovery specialist and a mechanic in the United States army, I drove a Hemet wrecker... What you guys are doing here is very intelligent being able to break test your gear like this. We do a lot of farming here in Arkansas with some friends, it would be really cool to get down to an Australian farm and see how you guys do it too. Mainly corn soybeans rice and cotton here.

It would be interesting to see what would break first on a receiver hitch. The pin that holds the hitch in, or the ball. Two D11s would be ideal to test that out.

I use those straps quite regularly and it's great to see how much they can handle. Very reassuring to know in case i make an error one day

Well done Mat and thanks for filming that test. Been earthmoving longer than I want to admit and being old school always use chains, but since watching your videos I have been thinking about slings to do recovering then you uploaded this video. It’s a no brainer now and a lot safer as well and no stretching chains.

Not often you get to play with d11s outside of a mine. Love the video, would love to see them with wire rope.

Glad you gave some shout out to the wood. It always amazes me how strong wood is. It can hold up very heavy loads.

Pretty impressive the amount of strength those straps have. As you mentioned, the weight compared to a chain.

This is the quality content we need ! We should try this with our equipment

Boy do I love the sound of two D11's spooling up. Great vid!

We used to use 2 0r 3 ton slings to stand 1.2 ton power poles, amazing vid thanks team Jackson.

Looking back I realized just how lucky I have been, we always used chains, and yes seen what can happen, these straps are impressive. I like the grousers extension worked👌🇭🇲😎

Daddy buys two D11s to keep the boys from fighting. Awwww...

I am impressed that you have 2 D11's.

The elderly gentleman to me looked to have a wealth of knowledge and also a humble man with a wealth of character. Sadly these fine Australians are dying out, never to return.

Today’s Showtime with the Jackson Brothers. 👏👏👏👏👏👍👍👍👍👍

Love seeing the D11s!

I saw a few of those 140 ton straps break in my day at mines. Saw even bigger straps break too. First time was when a haul truck got bogged in mud and two other loaded trucks were pulling on it. Next time was when a P&H 4100 electric shovel sank about 7 feet in muddy ground. We had 2 D11’s and 6 loaded haul trucks pulling on it. Took 3 days plus a lot of digging and pulling to get that shovel out.

nikt nie potrzebował ale każdy chciał zobaczyć, thanks Greetings from Poland

I love science. Awesome as always guys. Rock on!!!

The two D11s are super impressive monsters Great video iv worked with machinery and love the smell of diesel all my life Take care guys from Ireland

Excellent education Matt, Sunny lifting will be getting my order now for straps for the front end loader

Just another bloody good video Matt..keep em coming mate.. enjoyable.

Someone may have already mentioned that the remaining 3 straps had already been stretched, especially when down to 4. So 3 new straps might well have held. Pretty good value product, though, when you compare to what we 4WD people have to pay for a similar length strap :) Definitely there is a 4WD tax, haha.

You guys ROCK ✌️, much appreciated ✌️❤️

More of this, the power of the D11 is some thing else thank Matt cheers.

A D11 just sounds so awesome under load, thanks for the video.

I just build a huge D11 from technic Lego 😊 love your channel greetings from Holland 🙂

WOWZERS! I thought for sure the 4 was going to snap. AWESOME experiment, in the name of science!

You guys are about the straps while I'm: «duuuude ! people can own these D11s !? look how massive it is ! The engine is barely making any noise and it pulls 120 tons !»

Love the video I love watching those earthmovers mainly because I work on them everyday keep up the videos guys

Also worth noting the yellow cover (which doesn't do the work, it's the core that does( lets go first, to indicate that a major failure is close to happening

I do structural steel assembly, sometimes we use a sling like those when the crane boom is picking up enough static electricity from the air to shock us guys doing assembly.the sling in the hook serves as a insulator .and handles the load well ,very versatile rigging indeed Load softeners are a must in most situations.the only fault of a sling is the do cut easier than steel

Great video, thanks

You guys are awesome, your channel is awesome!

Great video Matt so interesting to see what the straps can pull have a great new Year

Interesting to watch. Thank you. I see those gold prospectors in Alaska on the Discoverie Canal fiddling with chains up to 10 tons. Dangerous but makes it exciting. Greetings from the Netherlands.

That was very interesting and jolly good fun! Just looking at them, you'd never think they'd pull the amount of weight they do especially when they're so light.

Damn that orange one is 140 ton strength holy crap, I wonder what they use that for

In the U.K. most equipment is rated at around 2/3 rds of the actual breaking point. A strap rated for say 6 ton will actually fail at around 9 ton ,a forklift rated at 6 ton will lift 9 ton etc etc. This allows for operator error.

Great video thanks for posting !

Comment for the algorithm,love what you do!

Impressive it gave a safety factor close to 10. Important to note the date of manufacture because they will get weaker with age. Lots of factors play into their safety factor. The fiberglass strands weaken with different elements such as being wet, temperature and age. Would be nice to see a follow up video in one year using the same amount of slings after being exposed to getting wet and a year of temperature exposure and normal use. I would imagine the safety factor drops down to about 6 with those same slings. Great test, thanks for sharing.

I see in some of the US farming videos they have a huge snatch rope with a knot system on the end .... never seen one of those break. We use these straps when lifting our engines around the workshop with a crane and cradle think out heavest is 13 tons , that a Q78 2 Stage Cummins ....

Pretty amazing how strong them straps are

just so you know, by australian standards, lifting slings have a safety factor of 8 .. so a 1 ton soft sling (purple in colour) will snap at about 8 ton .. so a 3 ton sling (your yellow ones) is about 24 ton .. that means you probally had about 70 ton on them 3 slings to snap them like that .. not bad for something thats only meant to be lifting 9 ton vertically

i’m here for the rain caps 😅 i love those things

I’d love to visit Australia seems like a beautiful place, it’s -24 c Here in Minnesota, USA tonight. Thanks for the videos!

Great content! Thanks for doing this.

this vid should be part of every mans video collection and played in every man cave world wide! lol Love this kinda thing

For a centennial celebration the people of taiwan engaged in a massive 200+ person each side tug of war. The rope broke with such force it ripped the arms OFF the first two people on each side.

Obviously the D115 had much better traction because the tracks had far less wear. Cant say it was stronger because the other one spun the tracks, so it came down to traction.

Great to see the mastermind making another appearance!!!!!!!!!!!!!!

Well done mates!!!! From the USA!

Great to know the capabilities cheers Team

It’s videos like this that have more to think about than most others. I can understand why places put a lower working limit on chains, cables, and straps to cover their butts the best they can.

A waste of money? Nah! That's pure science!

Your backup signal sounds like every Amazon delivery truck we have here in the States

Tiny 1 put your back! in to it or you'll be turned into spam cans, hahaha. Testing slings with D11's, it doesn't get better than that, awesome "work" gents.

Science at its best.. Thanks boys

Good stuff mate...interesting for sure 👍🏻

Is it just a co-incidence that the yellow cover breaks first? As well as offering some protection to the strap, does it also work as a visual safety device? I seem to remember going on a crane operator/slinger course at work. Though that concentrated on using the correct sling in the correct manner and not going over the Safe Working Load of the sling in the first place.

I didnt think for a second those straps would take that much pressure wow !

Everybody involved is FIRED! Someday I'm going to have a stroke when I come to and see two of my machines tugging against each other.

The wood used actually looks like it was heat burned to s certain degree. Job well done.

Amazing what a difference worn Track grousers make on pulling ability!

Fun video!

Крепкие стропы💪🏼

Great vid

Cool. New camera since the last time I watched. Sweet content, from this city bloke.

Love the videos and the fantastic experiments that you do. Just wondering do you have a brand of the straps or a retailer of the straps for your Australian viewers? Keep up the great work.

Unstoppable force, immovable object

Amazing you have two d11 for farming

The 3 straps were slightly different lengths. You could see them breaking one at a time.

Great video

Hi from the USA, thank you for the video. If you had a D11 buried in the mud, how many more straps do you think it would need to pull it out? Factoring in the added stress.

The average user won't even come close to breaking those straps.

So cool I'm jealous for sure You guys are my hero

God thems beautiful machines y'all have. Keepm coming yo lol

What he isn't realizing is by the time they got down to 3 , they were already stretched and at the breaking point. If the 3 were new, that would be a whole different out come.

Loved it.

Good way to dig a pond beneath them!

That was quite impressive that those straps held up to that.

Cool video

just wondering why the dozer was still in reverse gear while getting straps from the ripper? normally operator takes out of gear if someone is so close to machine, even operator out of cab.

Can you give a bit more info on the slings please?

Thanks for the slow mo.

NICE TEST....BRAZIL HERE......HAPPY 2022

So amazing video 😍😍😍😍😍

4:09 the sound 😄

Awesome 👌

Prediction: The one that moves first while the other is slipping wins, because the one not slipping has a higher friction with the ground than the one slipping. (static versus dynamic fricion).

Farmers have more fun!

That was fun to watch

Phew-weee amazed to see tiny 2 revved all the way up to 311 rpm and snap 3 like toothpicks 😇🤣😮
