Finding out lifting points that you may know existed?? Here in the UK, we have standardised symbology that has to be very near ALL the lifting points. I like your explanation but you have some missing factors that can't be checked as it is not that straight forward. I specialise in lifting containers for the construction industry, knowing the exact weight is essential but sometimes you have to overcompensate a ton or two. It could be container offices, welfare units, dry rooms, even generators.
About calculating the volume of that pipe. 1. Because you use the wall thickness and the diameter, it seems that the volume would calculate whether it was a pipe (hollow object) or a solid steel cylinder. So in step 3 your would end up with the same weight. 2. Why calculate wall thickness and diameter? Seems like you would use one or the other. Thanks
Please check your calculation on the volume of the pipe at 5:48 in the video as I checked it against my hand calculation and online calculator and get 4.61 cubic feet.
Once I had to determine the weight of a truck and if it was balanced or not. The method I use was to measure the air pressure in the tires and the area of contact of each tire. That way I get an accurate enough measurement.
Devon Sir, All of your lecturers are quite knowledgeable but you speak in such a hurry manner that it becomes quite difficult to understand for all those whose native language is not english
Devon no longer works on the Lifting & Rigging Channel, but thank you for digging into our library of videos. I hope you find that the newer videos are at a better more understandable pace. -Ben
Thanks for reaching out! We relaunched the Mazzella website, and so some of our old links aren't working properly, but I'm working with my web designer on how to square that away. In the meanwhile, let me grab your Email and I'll send it over to you. - Devon
Great question! First, we want to shy away from the term SWL, which refers to Safe Working Load. The preferred term is WLL, Working Load Limit. The WLL or capacity of a lifting product is determined by the manufacturer of that product and is usually a percentage of average ultimate breaking strength determined by the design factor (formally called the safety factor) applied to that particular product. Most, but not all, slings have a design factor of 5-1. (chains are 4-1) Most overhead and mobile cranes are somewhat lower and can be in the 3-1 range. Hope this helps!
I would like to ask what is the correct weight of material for Steel? Is it 480 Lbs per cubic Feet? As Acoording to your chart in the video. Or 490 Lbs per cubic Feet? As according from UBC Rigging Training Book on page 149.
How are load charts calculated I mean if I have a 50 ton crane how to know how much it could lift at a specific raduis and length or how to calculate crane rated capacity
The people I worked for 25+ years ago. Kept the Cranes "BIBLE" with every crane. Boom ange rotation position Height jib or not. Rigging remember lower boom angle and longer boom the less you can pick. Sling length and type.
Great video, thanks. Using metric units avoid the unnecessary step of convert from different distance units but I understand that is not easy to change once you learn imperial. I just learn how to use both and don't have any problems.
No problem at all. Glad you found it helpful! And if you need it, in the video we put together this Load Weight Calculation Pocket Guide if you want to keep something on you: ► www.mazzellacompanies.com/portals/0/pdfs/Mazzella_LoadWeightPocketGuide.pdf No forms or E-mails or anything. The link above takes you straight to the PDF that you can download or print out. Whichever way works best for you. Have a great weekend and thanks for the comment! - Devon

Very well explained, thank you!
Glad it was helpful!
the instructor has it going on to keep workers that don't know a whole lot about our industry. Awsome, job. please tell the Gentleman he did great.
Thats very nice 👍
This is great info... The core understanding... Much thanks... Keep these great videos coming!!...
No problem at all. Glad to hear you liked it!
Thanks for the comment.

This is very educational, so thanks for teaching the rest of us.

Explanation for zigotes
How'd he get the 5.85 tons🤔
Can someone explain why this chart shows "480 lbs per cubic ft. Of steel" everything i reference states it weighs 490 per cubic foot
I’m not understanding how you got 2.875
Great video. good for newbies starting out with lifting and rigging. The link to your lifting & rigging best practices infographic is '404'
Thanks for letting us know! The link is now updated - Kay

@@LiftingandRigging Ben, Thanks. Your Method of Teaching is quite amazing.
You could also figure out the pipe volume by treating it as a solid and then subtract the hollowed out portion i.e. (pi*r²h)-(pi*(r-wt)²h)
Wow so amazing
great vid, the pocket guide links are broken tho. is there another link?

WHATS THE CORE DIFFERENCE IN CALCULATING SLING SWL AND CRANE SWL ???
Great question! First, we want to shy away from the term SWL, which refers to Safe Working Load. The preferred term is WLL, Working Load Limit.

Thank you
Hi, I like your video. Thanks
Thanks! And thank you for watching!
It is really helpful for the personnel working in the oil and gas construction field . Really appreciated and Thanks for your dedicated hard work.🎉
Thanks for watching! Glad this was helpful.
I would like to ask what is the correct weight of material for Steel?
Is it 480 Lbs per cubic Feet? As Acoording to your chart in the video.
Or 490 Lbs per cubic Feet?
As according from UBC Rigging Training Book on page 149.
Thank you again for explaining the math correction.
It is 490, the video chart is not correct
Hi please tell me tree leg choker hicth
¡Gracias por compartir!
Blessings from Monterrey, México. 🇲🇽
Thank you so much for valuable information ❤️
No problem at all. Thanks for watching!
How do I change cubic feet to tons
How are load charts calculated
I mean if I have a 50 ton crane how to know how much it could lift at a specific raduis and length or how to calculate crane rated capacity
The people I worked for 25+ years ago. Kept the Cranes "BIBLE" with every crane. Boom ange rotation position
Height jib or not. Rigging remember lower boom angle and longer boom the less you can pick. Sling length and type.
Thank you for this video
How do you get 3.14 ?
Hey Billy!
Some of these calculations use Pi, which translates to 3.14 when solving the problem.
Hope that helps!
Best,
Devon
Great video, thanks. Using metric units avoid the unnecessary step of convert from different distance units but I understand that is not easy to change once you learn imperial. I just learn how to use both and don't have any problems.
I've heard a few different people mention how much easier everything is on the metric side!
Thanks for watching the video Rob!
Invaluable. Can't thank you enough.
No problem at all. Glad you found it helpful!

Sir super
Thanks for watching!
So how did you calculate the inches in to feet at 5:37
1.5”/12”=0.125’

Thanks!
"Pounds and cubic foot" ... Why can't you just use kilos and meters which is ww ..
nice vedio sir
Thank you for watching!
feet pounds and inches 😂
