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

    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!!

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

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

    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
      @Kspice9000 2 роки тому

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

      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.

  • @bwoodard907
    @bwoodard907 2 роки тому +2

    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.

    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
      @dpapfc  3 роки тому +1

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

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

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

    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??

      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 5 років тому +1

      @@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.

      @@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

    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.

      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
      @garybiggs9010 6 років тому

      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.
