- Tips for using the range diagram for the Grove Telescopic boom, carrier mounted crane. Using the range diagram is necessary for determining the boom height (tip to ground distance) and calculating wire rope deductions for NCCCO specialty exams.

I must tell you this but the way you explain and teach this subject is so clear, organized on point and very easy to understand you have that teaching 📦 gift
I appreciate this video, as well as many others. They have madevthe calculations much more easier to do👍🏼👍🏼
Very nice! Good studying material!
Appreciate the work. Very well done.
Good job, very informative 👍
I just want to thank you you really helped me out so much with this video
Good to hear Junior. I'm glad it helped.
Very good way for teach thanks
Very educative video. Thank you so much. Please, can you make a video about wire rope sling chart?
Thank You.
Good job
It's really helpful. Please help me find this particular angle and radius load to prepare the load chart
thanks
100% agree with the tips
I have one question about the final load chart, since the line fell in between 100 and 110 feet i thought that you were supposed to go with the smaller number, so shouldn't have been 100?? Thank you
My understanding on using load charts is that if your numbers fall between two chart numbers you use the one that creates more restriction. Since this exercise is finding out how much to deduct for the wire rope the larger number is used because there is more wire rope being used. If the rope being used is 2 pounds per foot the difference is 20 pounds on your load calculation between 100 and 110 feet of tip height. Same goes for boom telescoping, if you are between chart values, use the larger (longer) value.
Very useful topic
Perfect 👍
Thank you sir.
More video plss.thanks
Hello. I am taking my cco test this coming week. Do you have any videos on ground pressure and things that associate with that? Thanks for your time.
This may be too late to help you. I do not have any videos on ground pressure. It is an important concept that can show up on exam. Know which entities are responsible for ground conditions and methods for mitigating poor ground conditions--e.g. cribbing. You will probably will not need to calculate ground pressure. But if you do the formula is P=F/A where F is the weight of the crane and load and A is the contact are of the crane (where the crane contacts the supporting surface). These values are often expressed in PSA (pounds per square inch) so contact area should be in inches. But if you are asked For PSF the area would be in feet.
Could something like this also be used for the telescopic range of forklift like the JCB and the Magni line?
Hello Gary. Sorry for the late reply. Telescopic boom forklifts should have a chart that is very similar to a range diagram. The chart will be from the manufacturer for specific makes/models of machines. It will show the lift capacity at different angles, heights and reach distance. Check out this video ua-cam.com/video/3ANQ3HCCWpo/v-deo.html
good
Good
Is it the same for link-belt load chart?
Similar, but not the same. Sorry I don't have link belt.
@@LoadChartLab i mean but when I’m between hight in feet u go to the higher number correct?
@@juniorarciniega8694 yes same rules apply.
@@LoadChartLab thank you sir 🙏
@@LoadChartLab I passed thanks for the advice
If the radius is 10 meters but in crane diagram 10 meters is not there only 9m and 12m radius but in the crane load chart 10 meters radius is there and also the 12m,what crane capacity i will follow,for the 10m or for the 12m radius,but the question is 10m radius,tnx for the answer
I would need to see the range diagram, in meters.
In between values:
Boom Angle- lowest
Tip to Ground- highest
Boom Length- longest
Radius- longest
IS THIS CORRECT??
Yes. Sorry for late reply. I've been teaching a class all week and haven't checked my youtube messages.
if any of you people are taking you mobile cco' test know the difference between gross and net capacity...it may have been a load chart question on the recertification test...just saying
Yea, pretty common. Also can show up on the core.

Boom angle is 65
Why not round it to 70??
Boom angle you always go down to the next lowest--it's a manufacturer thing. Do this it will help get you the right answer on the test--LOL
Man this test is discouraging
Some of best operators I know had to take it 2 or 3 times. Hang in there. Know the regs and practice to build your speed on load chart problems.
Load Chart Lab thanks man just calculating the wire rope screws me up every time
Appreciate the work. Very well done.
More video plss.thanks
