In this video we cover:
0:00 - Intro
0:55 - What needs to be added to your lifting plan?
1:19 - Simple methods to determine load weight.
2:56 - How to calculate the weight of a load for an overhead lift
Example load weight calculations:
3:59 - How to calculate the weight of an aluminum block
4:51 - How to calculate the weight of a steel pipe
6:26 - How to calculate the weight of a complex concrete shape
7:45 - Free resources you can use in the field
Correction:
5:38 - Sorry we made a mistake in our math when making this video. Here is the correction. V=πr2h ID is 2.75 ft Radius (r) = 2.75/2 = 1.375 ft h = 8 ft V = 3.14 * (1.375)2 *8 V = 3.14 * 1.89 *8 V = 47.49 ft3

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.
Very well explained, thank you!
Glad it was helpful!
¡Gracias por compartir!
Blessings from Monterrey, México. 🇲🇽
This is very educational, so thanks for teaching the rest of us.
Glad it was helpful! Thanks for watching!
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.

Thank you for this video
Thats very nice 👍
Wow so amazing
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.
Invaluable. Can't thank you enough.
No problem at all. Glad you found it helpful!

Thank you so much for valuable information ❤️
No problem at all. Thanks for watching!
Thank you
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.
Hi, I like your video. Thanks
Thanks! And thank you for watching!
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
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)
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!
Sir super
Thanks for watching!
new subscriber is here
Thanks!
nice vedio sir
Thank you for watching!
great vid, the pocket guide links are broken tho. is there another link?
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.

So how did you calculate the inches in to feet at 5:37
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.
How do I change cubic feet to tons
Nicee
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.
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 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
Hello do you turn big things over with cranes?
Hi, *we don't, but our customers do! If you're interested in speaking with our crane specialist, visit www.mazzellacompanies.com/company/contact-us/contact-crane-division/
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.
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!
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.
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
Hi please tell me tree leg choker hicth
Explanation for zigotes
I’m not understanding how you got 2.875
feet pounds and inches 😂
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.

@@LiftingandRigging Ben, Thanks. Your Method of Teaching is quite amazing.
"Pounds and cubic foot" ... Why can't you just use kilos and meters which is ww ..
