As a truck driver, I had feeling this is what you were going to say. I just started in the crane business. Supporting a crane.

Preciate all the info. Have to re-cert tomorrow and brushing up on the basics. You would make a great trainer

This was perfect! Thank you so much for sharing this with us. Truly means a lot!!

Hey Jimmy! Excellent tutorial and very well explained examples. Much respect for your professional knowledge and your experience. These teaching videos are packed with info and you excel at getting your points across. The whiteboard presentations are the mark of a BOSS who knows his industry and equipment. Work safe, hope your weekend is going well! Doug@ the "ranch"

Good video. Straight to the point

Thank you for the info and going into detail.🙏🏽

Thank Jimmy I run a Hiab and your videos have been very helpful and reinforced what I have been tort. You use good plain examples. Keep then coming

At 6:40 you say 1# per ft. I was taught 10# per foot. Looks like you measured boom length for weight. They told me to measure tip of boom to ground. -nccco2019 Very interesting. Great video amigo

Good job mate,I am actually learning all my load charts in training this week ,there is a lot to it ,theory exams tomorrow and practical on Friday .

You did a great job explaining this. Have a nice Sunday.

I never came across the deduction for parts of line not used, like you said it is crane specific. We deduct all of the line parts for the net capacity. Usually a small number (in the order of a few hundred pounds) when compared to a lift weighing thousands of pounds. Also the weight of any below-the-hook lifting device ie spreader beam etc must be considered. This would be included in your rigging deduction though.......reading the load cart notes is a great piece of advice! Great video!

Thanks for sharing and take care. 👍

Hello jim. I agree with the stowed jib, erected jib etc deductions from gross capacity. As stated in crane charts and notes. However i have allways considered headache ball, hook block, rigging and spredder bars etc to be part of the load. Added to the load rather than deducted from the gross capacity. You get a completely different calculation of % of capacity. I humbly sugest you look into this. I know from experience of 44 years that this is a commonly misunderstood concept in lift plans.

Awsome thanks simple instructions all I need

Very informative, Thank you.

I have never been really good at math but was able to follow along and learn. Thanks

I start crane school on the 23rd or this month. This info helped me a lot. Getting out the semi truck 😎 thanks man

i finished crane school LAST November and well almost a year later I finally have my 1st job, I LOOOOOVE this video its an amazing refresher, now i just gotta be slow, steady and easy on the controls, and just get better each day.

Great Video!!!🤙🏾🤙🏾

Your do8ng great keep.it up I take cco test this weekend

Excellent video brother!!!!! Every crane operator should carry a cheap little calculator with BIG buttons in the cab with them at all times. They are or will soon be on sale too right now for the back to school specials. Our phones have a calculator in them but would you rather drop a cheap calculator or your phone? Trust me,,,,,you will drop them too,,, from the cab,,,,, most phone screens will NOT survive that fall,,,,, Stay safe out there guys!

Thank you Sir , you were very helpful.

Thanks sir I really appreciate

Great video Can you do a video on how to use the jib load chart when making a pick from the jib

Great tutorial 65yrs old and still learning thanks Jimmy.

Good jobs

Thank you sir !

Thanks for the math.can you do a video on how to calculate slind capabilities for rigging.

Thanks a bunch for explaining. What is rules to calculator fatigue of jib crane?

I know this is a very old video & Someone May have asked but do you mind specifying a few cranes that you know or have experienced that you DO in fact have to calculate for unused parts of line ? Or types of work/ Safety officials that require such practice ? I love your comprehensive clarity on the specifics It’ll be a great asset to my understanding if I had that insight

Great topic!

Keep on Jimmy, you'll have all a yer viewers here ready to NCCO test here directly. (( :

I'm short fat and bald lots of stuff skips right over my head lol. Good info easy to follow. Catch ya in the next one.

Is there a standard calculation formula for the crane capicty I mean if I know the radius and the main boom length can I figure out how much can a crane lift without the load chart

Thank you for all the information. I am from Québec Canada and i want to go to school for oparate Crane... They have a psychophisiologic test for selected the best candidat. I wounder if you can make a video of all the basic math and important knowledge so i can practice a bit more before the test. I see you talk about simple calculation like addition and soustraction etc. And more specificly Pi r2. (thank you for this information) But do you have any more specific calculation?? Thank you again, and good job!!

hey jimmy , long time listener first time caller I've been watching your videos and have definitely been interested in cranes. I see you're in my union. I'm on the east coast as a c branch member of 542. Just wondering how you got your start? Currently i'm studying for my nccco to get my boom truck and rough terrain. and obviously my core. I have learned many things while doing load charts. The more i've done the more comfortable ive gotten with them. i never realized that there's so many deductions with rope and making sure that you have the block correctly reeved and that you arent using too much line as to overload and use as a deduction. is there any hints or tips you could give out ? My grand plans are to get with a crane rental company maxim,amquip, or maybe even thackray. I'm 27 years old and already have my class A . I just have to re certify on a stick 5th wheel truck and i'll be good. have a great weekend your content is really good. especially when using crane terms and seeing them applied in video so i can accurately figure out whats what

Is the fly jib and boom extensions considered as load handling device and do I have to included it when I want to know the load gross weight

Do you have more videos on this? I operate a Kobelco CK850 III. I’m getting ready to take my written exam and I’m having trouble with the math among other things.

So your saying usually there’s a 15% of deductions on each lift but the crane is derated 15%, so it’s a wash. Get up on it hand.... 😁 nice video man!

Please make video on Calculating values of : Lifting Gear , Equipment weight of Tools and Plants ? Load on each leg (in Ton) ? SWL of D-SHACKLE , Bow-shackle ?

So IF you forgot to add in the extra part line, where would the breakage be on the crane? or would the computer simply say "Not gonna happen" Thanks for another great vid

I just renewed my ncco. Where were you last week Jimmy.

Not to be picky but, in a triangle the horizontal is "A" the vertical is "B" and the angle is "C". So, A square + B square equal C square. On your crane you said the boom was 200' long, the vertical leg or "B" is shorter, or C square minus A square equals B square. (If memory still works on my end) Thank you for a great whiteboard lesson.

Hey jimmy that was a great job explaining it!!! 👌🏽 I have a question...What does the jib do for the crane does it increase its lifting capacity or just extend the boom more?

Even if the jib is not erected on the boom, you still need to make deductions for it??

Do you pick up the rigging before the pick to get the weight? I didn’t think of subtracting the jib stowed.

This is good great job, can you go over more questions, I'm in school and I failed this part of testing because I didn't understand can you guide a little more

Are all of these calculations factored into an LMI?

👍🏻

I have a phobia in math, but I need a trade. Crane operator would be idea. I'm gonna do more research. So far so good but that dang math.

What did the old timers use before the on board scales? Did they have ways of knowing they were at capacity?

Actually, the weight of unused parts of line should be calculated by boom point elevation and not boom length multiplied by the cable weight per foot.

While gross vrs net I am well knowledge on However!! I was not aware of the extra weight limitation... An extra calculations... If I am plated for 80,000 an the rig weighs say 37,000 tare my Net weight would be 43,000 load capacity. If you know the load your hauling an manufacture load capacity say it is 42,500 .. your 500 under right? ""Wrong!!"" Most equipment manufacturer weight is given and dry terms. This is not allowed for the weight of fuel or oil or coolant or grease or mud .. an then we haft to add in the weight of chains and binders. Dot weight master lives to get into my billfold! But I see there more calculations then just gross, tare and net allowed involved and setting up the crane for a lift....That was a great video even for an old fart like me ...Thanks !!

Can you do online classes ?

भाई साहब मेरा कहने का मतलब है की बगैर लोड चार्ट देखें एक अनुमान, लगभग चाहे crane कितना भी Tone का हो अगर Lenth,Redius,Angle Load इन चारो मे से अगर कोई एक मालूम हो तो कैसे हम बताएंगे? कोई जरूरी नहीं है की हम हमेशा लोड चार्ट लेकर घूमे कोई भी कभी भी सवाल खड़ा कर सकता हैं मान लीजिए client face interview करना हो लड़का पढ़ा लिखा नहीं हो sin,cos नही मालूम हो तो फिर कैसे वो face करेगा ?

Jimmy, pie r round, cornbread r square.

BAD INFORMATION! . 200 feet of boom is NOT a 200 foot of rope deduction. You MUST use the Range Diagram to find the tip height.

I was good till you got to the algebra LoL

Talk slower.. I'm from the west coast... I don't hear that fast.

Writing too small
