TI 30 is giving me overload reading
Okay thank you i Already Understand, so we must converted 0.05 to Ln formula, so will get a -2.996
How you get -2.996?
Great work, I'm eager to look into it. I'll give feedback asap.
Good day How do I calculate STEL in excel showing in a graph. Thank you so much.
Sir, let me ask you a question not related to this particular problem is more like a general knowledge question, here it is (What is the maximum rope/cable/line length for a particular TLL crane? Sorry if my quiero is confusing but if you can understand and answer it it would be great, I always watch your videos I find them very informative how you explain step by step
Hello. Thank you for your question. There is not a single answer. It all depends on the crane and how it is configured. If you are asking about the maximum tip to ground distance (Length of rope from boom tip to ground)that can be determined from the range diagram and is dependent on boom length and angle. If you are asking about the total length of rope that can be on the crane that is a function of rope diameter and drum capacity-manufacturer’s documentation (manuals) will provide that information. Going to be different for every manufacturer and every crane model. A large Liebherr is going to be different the a link belt RT. I hope this helps.
What if it was a 12 hour work day, but an employee was only performing abatement for 85 minutes of the day?
There are adjustments (correction factor) for workdays exceeding 8 hours. Should be covered in the video. Also for some substance there are published exposure limits for 10 hr workdays. Record zero exposure for part of the workday not involved in abatement activities. If abatement involves lead or asbestos I encourage you to review OSHA guidance for exposure to those substances.
Sorry for my stupid question but whats the difference when the question says picking off the fly vs picking off the jib
The load is being lifted off the boom extension and not the main boom. (fly is crane slang for jib extension).
@@SafetyProCalculations so the fly and the jib are the same thing basically right?
@@linoloch yes
@@SafetyProCalculations got it thank you sir, do you have study material for TLL and LBC ?
@@linoloch yes. Go to loadchartlab.com
Great video! Thank you for sharing
This is new phenomenon on my mine in South Africa. I am here because we did a practical study and found that the coal dust fines are not adequately extracted/exhausted when crushing/pulverizing and using air blowers to clean these equipments. Thank you for this info
thanks for this Dr Doug! I have a one man metalshop over here in MD and occasionally I have to lift odd-shaped heavy loads. This videos will help me be safer and more efficient.
Hi great video. Do you mind sharing your email address? I have a question I would like to ask
So to be clear. Any time you have the line hanging in any amount you know you are using the other block correct?
Yes sir. If it says something like "10 feet below main" that means picking off extension. "10 feet below extension" means picking off the main.
@SafetyProCalculations one more question. So in the event I'm calculating line using the tip height. The range diagram falls between whole numbers. Do I jump to nearest whole num like 90 or a 5 like 85? I know this is a fuzzy area on the TLL specialty test. I'm preparing for a retest next week
@@mikemangino854 You should check out my other channel, Load Chart Laboratory th-cam.com/channels/_LYfJVjTab5VZyr2sh6-qg.html. I have about 40 examples where I work through load chart problems, step by step. I've got example for all three types of mobile cranes covered on NCCCO mobile crane specialty exams.
This was very helpful. Thank you.
that carbon and hydrogen doesnt need times with 2?
Silly question, what does the 'n' represent in the formula ? ie Cn Tn ??
Not silly. In a work day there could be three, four, five, or more concentration periods. The n is just mathematical notation telling us to included all the concentration periods. Does this make sense to you?
@@SafetyProCalculations Yes, thank you for the explanation.
Where are the Total and static pressures acquired ? if it is a open ended pipe with a suction fan at the other end i static pressure atmosphere ? and total pressure what's that ?
The Branch duct answer v=566.18fpm Your answer is 297.2 please check the clculation again. 10(0.42)+0.196 here in this step there is some problem in ur calculation. Thanks for your wonderful videoes.
Thank you so much for this video, the math for the BCSP ASP is REALLY hard and I've been so stuck here at home alone without further instruction beyond the formulas. I appreciate you taking the time to do this more than you'll ever, ever know!!!
Given a fan of 3018 as rpm how do I change that to m³/hr
Super helpful for my class - thank you so much!
How to calculate 500 ton cranes outrigger pressure psi each outrigger.
Pressure equals force divided by area. Weight of the crane and load divided by the total area of the contact surfaces. Divide that by the number of outriggers. Pressure will not be equal on all outriggers at same time. If loaded boom is positioned over an outrigger the pressure on that outrigger will be greater.
Thank you very much buddy for your reply possible just explain the formulas example some lifting 20 tons using 500ton crane main telescope 30mt and 54mt luffing jig.
@@leonardaquiela9418 just to be clear, make sure you are using actual weight of crane, not the crane’s capacity. A crane with a 500t capacity will not weigh 500 tons.
How to check luffing jig radius while lifting height is 36 and crane radius is around 46 meters.
Draw me a diagram of the configuration. Label it with the measurements. Also what’s is the boom angle and jib offset?
One of the best explanations of OEL's. Thanks, much appreciated 🌄
Very valuable 👍
Thank you so much !!!!
So Only deduct 4 parts of line?? Instructed to deduct 8 parts of line in class today??
In the problem I'm working through in the video the crane is reeved with 4 parts line. Yes only deduct 4 parts line, tip to ground distance. Would also deduct the 10 feet of line hanging off the jib. Hopefully the problem you had in class was reeved with 8 parts line. LOL. This is hilarious.
Sir you guide very well i am big fan of you
Thank you
you made this so easy to understand, thank you
Thank you SIR: excellent pacing and clarity.
If your using the whip line would you still count a block as part of the capacity if you using line pull instead of the chart ??
Block is a deduction. When calculating net capacity the weight of the block is deducted from the gross capacity. Doesn't matter if line pull or chart capacity is being used as gross capacity.
Perfect video!! I must have searched dozens of topics to find the answers I needed which you very informatively provide in this video! We need more videos like this from English native speakers, I am so confused as to why these videos are so hard to find in English!
Good. I'm glad the material is useful for you. I have another TH-cam channel that is all crane stuff. It's called Load Chart Laboratory.
Best stuff on the market got a 100 on the grove test back then before when that test was around….great real life load chart examples and videos to follow great job chief….if you ever do lift Director nccco practice question 🙋♂️ please let me know now that’s a hard test! Thanks
Thank you. I’m kicking around the idea of going full time as a crane test prep trainer. Yes lift director is a good one-good meaning tough, lol.
I must say, your video is truly insightful! I greatly appreciate the knowledge and information you have shared. However, there is one aspect that has piqued my curiosity. I would love to learn how to determine the coordinates for specific parts of the object you discussed in your video. Could you please kindly provide some guidance or instructions on how to find out the coordinates for these specific parts? Your response would be immensely appreciated.
Good information ❤
Hi
Hello
thank you sir.. so wonderfully you explained
Perfect video man! ty so much
Can you please also do Leq time exposure calculations
Hi,is it universal that on all charts the distance out starts at the front of the tires,and zone 1 boom angle begins at half the lenght of the forks?
generally speaking yes. But always follow the manufacturer's instructions for interpreting the charts.
@@familyoftwo7441 I agree assuming the sensors are not out of calibration as they often are.
I Am a Rigging Engineer. Learning a lot from you. Just within a short period. my greetings from Lusaka Zambia 🇿🇲
Thanks for the refresher. Might get hired to work with these after years🙂👍
Thank u sir
You are welcome. I'm glad to be of assistance.
What is the Natural Logarithm value?
The natural logarithm lnx is the logarithm having base e, where e=2.718281828....
Thank you so much Dr, please do you have a PDF documents of your courses? IF YES ? WHERE CAN i FIND THEM PLEASE?
I'm sorry. Full course materials are only available to students enrolled in the EHSM program at Northeastern State University. I recommend you study a variety of safety management/safety science textbooks such as Barbara Plog's Industrial Hygiene book.
Dear Sir, awesome video, really useful…Would like to request if you can explain or make a video on how to determine the cog of an item or beam by performing lift check at both end of the load. If there’s already a video on this, appreciate if you can share the link. Thank you.
Try this one. It may be what you're looking for. Crosby (the producer of this videos) is greate. th-cam.com/video/_fX88demoaE/w-d-xo.html
Great video Dr.. As an EHSM major I highly recommend weighing EHSM as an option for ones future!
Just what I needed..
I have an opening sized at 414mm X 326mm covered with 3mm wire mesh, system requires a minimum of 2.4m3/s of air flow, how do I calculate the correct removable air filter to be fitted in front of wire mesh?
In up coming days i will have interview can you make more videos related to calculation and interview question and answer to a rigger
