How to video explaining the Basic Rigging Calculations required to complete the Australian basic rigging high risk licence assessment. Subscribe / @kieranstraining
As a total first timer who was just told to get my crane licence I was following everything he said up until he gave the Angle factor number of 1.73 as the number you arrive at if you multiply 4510 x 60˚...My brain shut down and now my right eye is twitching lol Also, just to add way more spice to this story... I live in Japan of all places and I'm going to have to do all of this in Japanese...which is why I'm here now trying to understand everything in English first...I suck at math BTW and the Japanese text book I was given is full of really scary looking mathematical formulas that look like hyroglyphics to me...
Great tutorial very imformative, logical fundamental explanation. will start to practice the formulas. Can you please show me a groved and an uncgroved drum.
Great video! One question your AF is based on a right triangle used in trigonometry. Is this used through out all rigging training? Reason for asking is I watched a Crane Training for Sling Angle factor and for the used 90 degree as 1, 60 = 1.155, 45 = 1.414, and 30 = 2.0.
Hi Kieran. Love the training vids. This one has helped greatly. My only question is how we arrive at the figure 20 (@ 10:00) for our sheave friction factor given my paperwork indicates 5% per sheave. A little confused as regardless of the number of sheaves in the PURCHASE + the LEAD SHEAVE + any additional DEFLECTION SHEAVES, the figure in the formula remains 20? Is this correct? Cheers
There are two ways to find 5%, you can÷20 as in 100 ÷ 20 = 5, or x by .05 as in 100 x .05 = 5. The reason I divide by 20 is fewer mistakes students make rather than introducing the decimal point
hi Kieran i really appreciate your Teaching and i have learned alot from you mate, just one question how does Grooved drum becomes 12 and plain is 19?how does FAR arrived at this figures?
Gday Reece it is divided by 2 is the fleet angle is calculated on an angle from the centreline of the winch drum, thus dividing by 2 to find the centre
Look away for 2 mins and the whiteboard is blowing up. Haha. Good video mate.
Kieran, you're a frickin hero man! Should be wearing a Cape in these videos! Much appreciated. 😊
Thanks Stephanie, I'm glad the videos are helping, but I reckon a cape may be a bit of overkill.😂
I should have watched till the end. Thanks for the great info!
Excellent teaching Keiran 👏 👍 👌
Everytime Kieran says "Alright." Drink.
I'm drunk @3:18
Jokes aside. The videos are great mate! You're a wealth of knowledge

Thanks mate. VOC on Tuesday👍🏻👍🏻
Thanks for the demonstration!
No worries I hope it helped
Thank you, such a clear demonstration
Damm you’d be a handy bloke on site to have around
Got my rigging course starting tomorrow, this will help heaps. Thanks mate !
Good luck Tain
Did this help? Got my rigging course starting in a week
@@ye4702 yeah mate it did, just getting a head start on the information was a good way to go into the classes.
Hi Kieran, please explain how you would calculate the weight of a frustrim cone to be lifted from a crane.
Lovely mate , thanks 🙏🙏🙏🙏

I do a video on the block and tackle from multiple lines, and then single part lines

wouldnt (3340 x .05)7 + 3340 work as well? Also those are some hella efficient pulleys. most of ours are around 10% on the high end

Join the rigging and lifting group
Can you upload the basis dogging course again
Hi mate,
How do you get 1.73 from the 60 degrees?
Angle factors you will need to remember are 1.73 for 60, 1.41 for 90 and 1 for 120 degrees.
It has taken you 27 minutes to answer one pic! How can you do it 2 min on 26 question test in one hour??
questions on a taest
are you James dunkan trainer in AST before
No I'm not
Why do you divided buy 2 with first calculation
Gday Reece it is divided by 2 is the fleet angle is calculated on an angle from the centreline of the winch drum, thus dividing by 2 to find the centre
@@kieranstraining thankyou for the reply keep doing your vidieos as they are very helpful
