Choosing the Best Lifting Sling: Wire Rope vs. Chain vs. Synthetics 

Thanks, Oscar! That's not a problem at all. Glad to hear you found it useful and stoked to hear you're using it in your safety talks! All the best, Devon

Thanks Aziz!

Thanks!

Thanks!

Always better to use wire or synthetic slings. Although there are a few exceptions. A chain fails without warning and is only as strong as the weakest link.

Rory, thanks for the question. I reached out to one of our rigging trainers, Nate Fisher, for an answer. This is what he had to say. "Dynamic Loads can create a lot of stress on the slings, regardless of the material they are made out of or the weight of the load… There would definitely be a lot of concern about breakage or failure. Slings and other lifting/ rigging equipment are designed to take up the weight of the load gradually and steadily. They work best with controlled, static loads. That is the safest way to lift. Knowing that you are working with dynamic loads, you must be vigilant with your inspections and inspection criteria. Have a procedure or plan in place for inspecting your equipment regularly and often." I hope this helps. Let me know if you have any other questions.

@@LiftingandRigging i appreciate the hell out of the response. having an inspection plan and criteria seems like the cover charge, the minimum we all should be doing when working with heavy loads. thanks again

Rory here is a bit more information from another one of our trainers. This is what Bob Gubanich had to say. _"The definition of “dynamic loads” is *any load that changes over time.* If that time period is very short, it could be defined as a shock load. Shock loading can occur *in any situation where the load on the crane and/or rigging suddenly increases.* Intense shock loading can create stresses on the crane and rigging equipment *many times* the static weight of the load and is one of the most unpredictable causes of catastrophic failure. Four of many factors that can contribute to a catastrophic failure are: Ultimate breaking strength (UBS) of the slings and crane (design factor and WLL) Weight of the load ( percentage as compared to the UBS of the lifting equipment) Severity of shock load ( do the created forces exceed the UBS of any component?) Overall condition of the crane and rigging By using the equipment at a lower percentage of its WLL and of course, its UBS, you reduce the chance that the shock load force will exceed the UBS of the equipment. If any of the equipment is damaged/worn etc., the UBS will be lowered, and the risk of catastrophic failure will increase. So….yes, anytime we perform a lifting operation, there is always a risk of breakage or failure. The competent person performing the lift must take appropriate steps to mitigate that risk, including, but not limited to; a lift plan, including some of the calculations listed above, and a thorough inspection program for all cranes and lifting equipment."_
