Destructive test of 12 tonne Straightpoint Load Shackle

Test to show a destructive test carried out for us by our partners Van Gool BV in The Netherlands.
The product is a 12 tonne shackle loadcell, it snapped at 66.9 tonnes

I cried when it broke. But I knew it had to be done for the benefit of mankind.

[@peterritchie2990]

I almost did but I buckled up.

[@jasonlavelle3293]

12t for 4wd is plenty but I couldn't believe that it took more than 60t to break it, very strict restrictions

[@mbrooksay]

for something you're using everyday, you're accounting for wear and tear on it a little. you wanna trust it

[@theSkavenger84]

This was probably good USA made metal too. Not cheap crap

[@joevenator5792]

To my knowledge all overhead rigging in the USA has a minimum of 5 to 1 safety factor

[@rslayton3283]

Very informative video. The narration was top notch! So everyone knew what they were watching and could take that information and apply it at the job site!!!😏 If it ain't Crosby...it ain't on my job!!

[@bradzee9947]

Very good show!! I use these types of shackles all the time and was wondering what they break at!! Thanks for the video.

[@ats-3693]

And the shackle itself didn't even break the bolt did.

[@montanasnowman3138]

It's only rated @12t but think about why it actually failed at 60t.
Shock loading
You got something real heavy with a chain or a cable attached to something really stuck or really large floating and you're giving it a hard tug.
That initial enertia "breakout" force if you will is why the restrictions are designed into this piece at such numbers.

[@Kspice9000]

I imagine. That's why if you see any break, it's as soon as it's tugged with high tension.

[@brucewinningham4959]

Montana Snowman, I think the producer of the video should have let us known that. THANKS for the pertinent information.

[@jaxturner7288]

A standard safety factor of 3 or 5 applies to most lifting equipment but once shock loaded they lose their integrity and should never be used for overhead lifting again after that.

[@WineScrounger]

Safety factor of 5, good enough for me
🤜*🤛

[@davidsirmons]

What number of steel is this? Forged also I'm guessing?

[@Barnekkid]

5 to 1 design factor.

[@user-lw3vq2ku3e]

How mach ton shackle? 5÷1

[@ianmoone2359]

Confused! What bow shackle uses a bolt with locking nut on the end as it’s pin?
Everything I’ve seen uses a pin that’s threaded into the opposite side of the bow shackle leg?

[@dpapfc]

It’s a safety shackle - uses a bolt, nut and split pin.

[@pubgclips9722]

these shackles are used for long term use, .. screw pin shackles are used for quickly unfastening mainly in rigging works

[@Agent.K.]

In oil industry they use these mostly. You rarely see the bolt only type which is common for 4wd.

[@bwoodard907]

And the standard safety rating is 5:1 I believe and 25:1 on block and tackle set ups mainly sheaves. More than enough rating.

[@garyhicks1473]

6:1

[@haquim2804]

Safety factor of 5

[@TheBrewjo]

Groovy!

[@rustybrowneye]

Neat

[@amitdube888]

D cycle or bow cycle me kya antar hota hai batao bhai

[@dpapfc]

It’s a bow shackle

[@dob2030]

Wow

[@angelo_giachetti]

Perty cool

[@tonyblackie3277]

Sorry, I completely missed what was going on :(
Why were no units mentioned? It seemed to break at 6600 odd units of something. Pounds?? in which case broke far too soon. Kg? still too soon? Can someone please explain??

[@gabrielagudelo7828]

Load cell screens usually uses tons, Tony. The shackle was designed for 12T but destroyed at 66.9T. It is written in the description.

[@tonyblackie3277]

@@gabrielagudelo7828 I think you have missed the point. 6690 units (kg?) /whatevers would indicate 6.69t not 66.9t. So, confusing as it looked like breaking at half not over 5 times rating. Other load tests seem to use multiples not tonnes, others again lb etc. Again not clear. The heading only states the rating not breaking.

[@danielwatkins8208]

Tony Blackie the way the scale climbs you can work the Decimal point. Plus the only measurement they have given is is tonne. Don’t let these things confuse you. USA ?

[@AndrewBrowner]

@@tonyblackie3277 if you take the 3 seconds to read the description (or for you probably more like 30 seconds) youll see it broke at 66.9 tons over 5 times its rated load... also with the size of the equipment and the clear decimal point on the scale i dont see any unit other than tons that they could be using

[@tonyblackie3277]

@@AndrewBrowner Hardly a respectful answer andrew, and I do admit that I sounded a bit strident in my confusion. Different parts of the world use different scales. What seems clear to you is not necessarily to others.

Chuck Norris' old job. Machines put him out of business.

[@garybiggs9010]

The shackle was not rigged properly. The shackle bolt needs to go through a bored square bar. You put the heavy testing shackle loop against the test shackle bolt which created a single point of load bearing. I would not hire you to change my oil.

[@dpapfc]

This test was not done by us Gary but at an outside test house. The shackle bin had a lot bobbin fitted to centralise the master link and speed the load across the throat of the shackle.

[@garybiggs9010]

Very sorry, I stand corrected. I see the bobbin now. I watched another video previous where they used a pull link without a bobbin and sheared the shackle bolt on one side that the link slid to.
