Is two 1t slings the same as one 2t sling? Or will this cause a failure in the system, should one sling fail, then the remaining sling becomes overloaded?
I reached out to Terry Driscoll, someone with decades in the lifting industry to get you an answer. Here is what he had to say. "I would never rig like this. Here are my main concerns - • Matched length would have to be EXACT to allow both slings to carry the load perfectly. Not worth the risk, especially if you are dealing with wire rope or synthetics to get the matched length. • Even if the slings are exact in length if the load shifts or angles are introduced, one sling will see more of the load, and now you are entering proof load capacities, which is not a proper way to rig within the design factor of a sling. There are “catch slings” that are used in some applications, designed to handle the load if one sling fails, but that would not be the intent of this rigging set-up based on the request.
@LiftingandRigging That makes sense. I was thinking if one failed, both would fail. I didn't stop to think of imperfections. Now that you've pointed this out to me, I realise it is impossible to make two slings perfectly identical, so naturally, one would be the main bearer and the other just along for the ride. Thank you for your fast reply and thanks a lot for your fantastic videos. I have learnt quite a lot from your channel. I look forward to watching more.
Good question. The answer is no. A "hitch" refers to how the sling attaches to the load it is picking up. I.E. - basket hitch or choker hitch A "bridle" simply refers to having multiple sling legs from a single point. I.E. - a 4--leg wire rope sling bridle, where those 4-legs connect to a single master ring.
Wow you have such a great lecture a high knowledge in rigging job and their different comfonent that can be apply to our daily routine in any work place like shipyard refinery or a high rise construction work, thanks. For ideas God blessed and keep safe
I can’t help but notice the channel doesn’t exactly have a playlist or even a video breaking down some of the more complex trigonometry that is involved with proper load balancing & measuring. I also haven’t seen anything specific about stage rigging and I’d be very interested in that
Hi Greg, great question. This is a tricky one to answer as the government may have different instructions compared to ASME. I reached out to Brandy Cooper who works in Government Sales for Mazzella. This is what they had to say. "There are many manuals, specifications and drawings for handling explosives and weapons. The government instructions sometimes supersede ASME and other times refer to it as the governing requirement - It can be quite tricky. Typically explosives are going to have unique gear designed for the item being lifted and will have a drawing which details the test loads and test configuration. Below are the main manuals/references and they will often refer to the appropriate test instruction that should be used for each item. • Approved Handling Equipment for Weapons and Explosives, NAVSEA OP 2173 • Ammunition Afloat, NAVSEA OP 4 • Ammunition and Explosives Ashore, Safety Regulations for Handling, Storing, Production, Renovation, and Shipping, NAVSEA OP 5 Additional references…. • NAVSEA SG420-AP-MMA-010 - Periodic Testing Arrangements for Ordnance Handling Equipment • NAVAIR 17-1-127 - Periodic Proof load Testing of Weapons Support Equipment W/IPB • TB-43-0142 - Safety Inspection and Testing of Lifting Devices • NAVSEA OP 4098 - Handling Ammunition, Explosives and Hazardous Material with Industrial Materials Handling Equipment • NAVSEA OP 3347 - Ordnance Safety Precautions, U.S. Navy • NAVORD OP 4 - Ammunition and Explosive Safety Afloat Hope this helps - let me know if you need additional information."
Great question! A lowercase t means the WLL is measured in Metric tons (tonnes) which equals approximately 2,205 pounds, while a capital T means the WLL is measured in short tons equaling 2,000 pounds. So you need to pay attention to which "ton" your manufacturer is using. We have a video covering this topic coming up soon. So stay tuned.
all i can say is where i work the rules and the safety enforcement are very strict as they should be, the problem is this site is huge. and it so happens to be my place of work is on the outer fringes of it. and boy can i say almost none of these rules are adhered to. everything that was thought to me, i saw all these things immediately violated.

these are tips everyone should remember!
Thanks for watching.
This is a channel many of my coworkers should watch.. excellent work guys !!!
Please share!
Thanks for the video. It's definitely one to be saved .
Glad it was helpful! Thanks for watching!
Thank you for the informative information sir.

Is a bridle another kind of hitch
Good question. The answer is no.
A "hitch" refers to how the sling attaches to the load it is picking up. I.E. - basket hitch or choker hitch
A "bridle" simply refers to having multiple sling legs from a single point. I.E. - a 4--leg wire rope sling bridle, where those 4-legs connect to a single master ring.

What is plane in rigging and slings?
Such a happy man

I love the channel however and appreciate your videos immensely

@@LiftingandRigging You’re awesome man. You actually care.
What "ton" is used for lifting equipments? short ton ou metric ton?

@@LiftingandRigging , thank you só much... but i yet have a doubt... what of them is used in nowadays stardards?
Very nice videos of rigging job, it's my life river...
Thanks 👍
Awesome buddy
Much appreciated!
I got offered a job doing this.. lol 😅 going in to heavy equipment operator soon just seeing what's it all about
Congratulations! As you are getting up to speed be sure to let us know if you have any questions.
I have a FEW theatre install from the deck to the grid rock and roll shows grun😢d rigger and climbed also movie pictures house loved
Very attractive thank you
Damn, not the rigging i was looking for, very educational tho 👍
Also looking for stage rigging?

You look exactly like the dude from the movie Rampage
Thanks! People tell me I look like Dwayne "The Rock" Johnson all the time!

Thanks for watching! Glad it was helpful.
Very hard😔
You can do it!
@@LiftingandRiggingone day as a lifting engineer, thanks😁😁😁

The reason I nearly fell asleep in my first class was the semi-monotone, teleprompted way of speaking.
Good info, but the presentation is a bit stiff
Thanks?

I’m in Canada so half of what u said was a waste of my time
Sorry, Canada.
@@LiftingandRiggingin terms of explaining what osha asmr ect. The rest was all useful thanks. 👌
