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.

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.

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)

@RobbsFamily Жыл бұрын

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

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.

Can someone explain why this chart shows "480 lbs per cubic ft. Of steel" everything i reference states it weighs 490 per cubic foot

WHATS THE CORE DIFFERENCE IN CALCULATING SLING SWL AND CRANE SWL ???

@LiftingandRigging 3 жыл бұрын

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.

@michaeldaniels8574 Жыл бұрын

Thank you again for explaining the math correction.

Hey Billy! Some of these calculations use Pi, which translates to 3.14 when solving the problem. Hope that helps! Best, Devon

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

@jerrykinnin7941 Жыл бұрын

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.
