2 Minute Tool Box Talk on the Effect of Sling Angles on SWL

Please visit lms.albertabcs... for more information.
This is a short excerpt from our Rigging and Signalling Fundamentals 101 course that illustrates the effect of sling angles on the safe working load (SWL)

Thanks for this knowledge.

[@boydhanel9467]

Great video. A good review for me. Maybe add another video on how temperature or other factors can affect a slings lifting capacity.

[@Allegedly2right]

Makes perfect sense I knew I wasn’t 18 Stone must keep my feet together when I step on them scales in the bathroom.🇬🇧

[@jagmasters7392]

Nice tutorial thanks! Sub'd to this channel as a result 👍🏽

[@nategibbons172]

The Crosby Group has many videos that go over lifting.

[@محمدابوالنور-ث2ر]

Great video may God bless you

[@emanuelmatos5737]

Great, very useful video.

[@Albertabcsafety]

Glad you think so!

[@tahseenjawaduppal6536]

Hey, you calculated the force but what was the angle there? Does angle have no role in final calculations? Please clear my confusion as my interview is near..

[@Albertabcsafety]

Thanks for your question. The formula shared in this video gives the approximate actual force on the sling that takes into account the sling angle.

[@nategibbons172]

The angel plays a part to give you L/H which is your multiplier.

[@heroscapewarrior4217]

How come the angle isn't included in the formula for calculating how much load is on each sling if the more u decrease the angle the more tension?

[@jesuschrist2174]

Question on length of lines, do you measure the total length of rigging sling etc or exact length from object to hook? I’m probably over thinking it ?

[@HumphreyDeFirst]

You always work with perfect lengths, for safety, but if otherwise one sling will obviously have to carry/pull more weight.

[@jesuschrist2174]

@@HumphreyDeFirst I be trying to do the sling tension formulas in my head

[@HumphreyDeFirst]

lol. you can do you calculations before operation or before coming to site, typically the weights of loads should be known by all parties before lifting/moving

[@goldiesob]

How did you get the number 6 on the vertical ? Thanks!

[@Albertabcsafety]

Hi, it's a measurement from the bottom of the hook down to the load. You would have to measure it. There are other ways to find out the number without measuring it, but you would also need to know the distance from the hook-up points on the load. Hope that helps.

[@sunnylusburner8108]

Where does the twelve come from?

[@yonguru]

Number of slings times the vertical .. two slings times 6 is 12

[@nategibbons172]

Your video is misleading. You You need to still find COG and calculate the vertical share. This demo is ONLY for COG equal distance from each pick point. That is a key factor.

[@baskars9577]

How to find a 'H"

[@khetamir5416]

using trigonometry

[@nategibbons172]

Pick a point and measure the length and the hight from that point. The angel doesn’t change so if you measure 4’ up then 3’down, is your multiplier. 4/3. L/H.

[@oliverbronola1488]

I'm sorry but you are wrong...how come that each sling has tension of 4200 pound....

[@Albertabcsafety]

It's physics

[@Jacobus-b7m]

you look at wrong angle
