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"
@@barryhansen6854 we had a good time. We went to Universal Studios and Kennedy Space Center. Lots and lots of walking. Also, lots of driving. Hence the reason I look tired in the video. I drove straight through from Florida to home yesterday and today. 22 hours of driving is now my new record. Lol
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.
If you don’t mind me asking, how hard was crane school and where did you go? I’m looking at going to crane school and figuring out if it’s worth it/find a job after/how difficult the math is, etc.
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!
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!
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.
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
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
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!!
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
@@ToTheTopCrane I have often thought that if you, ron pratt, lets dig 18, and brandon (and many others) got together with Mike Row works and put together an online university of the trades. it could show that working with your hands is fun, cool and exciting. we need to get more young people to take up building things.
Most of the time we know what the rigging weighs beforehand. A stowed jib makes a big difference sometimes. So, it definitely has to be accounted for. It gets missed by lots of people though. So much so, that some jobsites remove the jib completely. Many thanks for watching! 🙂
We are supposed to understand our charts and be able to do the math and know the weight of our picks and not rely on the computer. Our lmi is an operator aid not a replacement for understanding what we are doing.
Crane Fan I understand that. But I have seen some of jimmy’s videos where the estimated weight was different than the actual. It would seem that without the on board scales and equipment it would be easier to exceed your capacity.
Agreed. What I’m emphasizing is that as crane operators we need to develop and maintain our skills to make the calculations manually, and not end up like the person that blindly follows their gps into the lake and drowns
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. Kelly.
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
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
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?
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.
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 ?
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
Did you end up graduating school? Was it worth going to? I’m looking at going to crane school. Just nervous it will be hard to find a job after and that the math will be too much for me
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 !!

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

You did a great job explaining this. Have a nice Sunday.
Thank you! Hope you have a nice Sunday as well. 🙂
Great tutorial 65yrs old and still learning thanks Jimmy.
Thanks Barry! Hope all is well down your way. Many thanks for watching! 🙂
@@ToTheTopCrane been raining for the last 4 days but all is well hope you are handling the heat you are getting?
@@barryhansen6854 we just got back from Florida this morning. I think we missed the worst of the heat up here.

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
Thank you for watching the videos! Glad they are helpful. 🙂
This was perfect! Thank you so much for sharing this with us. Truly means a lot!!
Good video. Straight to the point

School was 4 weeks in Colorado. Just Google nccco test sites.
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 .
I have never been really good at math but was able to follow along and learn. Thanks
Thanks for following along and watching! 🙂
I start crane school on the 23rd or this month. This info helped me a lot. Getting out the semi truck 😎 thanks man
Was you able to find a job after? Was it worth going to?

What is rules to calculator fatigue of jib crane?

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
Keep on Jimmy, you'll have all a yer viewers here
ready to NCCO test here directly. (( :
That would be awesome if all the viewers passed the NCCO test because of my videos. Lol. Many thanks for watching! 🙂

Great Video!!!🤙🏾🤙🏾
Do you pick up the rigging before the pick to get the weight? I didn’t think of subtracting the jib stowed.
Most of the time we know what the rigging weighs beforehand. A stowed jib makes a big difference sometimes. So, it definitely has to be accounted for. It gets missed by lots of people though. So much so, that some jobsites remove the jib completely. Many thanks for watching! 🙂
Your do8ng great keep.it up I take cco test this weekend
Awsome thanks simple instructions all I need
What did the old timers use before the on board scales? Did they have ways of knowing they were at capacity?
They would feel the crane start to tip.
To The Top Crane so they were literally flying by the seat of their pants.

Great video
Can you do a video on how to use the jib load chart when making a pick from the jib
Thanks for the math.can you do a video on how to calculate slind capabilities for rigging.
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.
Thank you! I'm short, fat and almost bald. So, don't feel bad. Lol. Many thanks for watching! 🙂
That's why you wear hats. So the bill will help catch it.
Good jobs
Thanks sir I really appreciate
Even if the jib is not erected on the boom, you still need to make deductions for it??
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
Thanks for sharing and take care. 👍

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?
A jib will lower capacity as you are putting more weight farther out, which has high leverage.
Oh ok thank you for answering my question really appreciate it!😂
Thank you Sir , you were very helpful.
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.
Are all of these calculations factored into an LMI?
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 ?
I just renewed my ncco. Where were you last week Jimmy.
Great topic!
I can't take credit for the idea of the topic. I wish I could remember who recommended that I talk about it. Many thanks for watching! 🙂
Very informative, Thank you.
Thank you sir !
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!
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
Did you end up graduating school? Was it worth going to? I’m looking at going to crane school. Just nervous it will be hard to find a job after and that the math will be too much for me

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.
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 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.
