A train of thought regarding load capacity for recovery vehicles brought me to this video. Found your explanation very clear and streight forward, reminds me of my loadmaster days when we used to do manual load sheets for aircraft.
I'm 28 and have been an rt operator for 8 1/2 years both swing and down cab. My resert nccco test is coming up along with a new guy thats going to go through his first time. And this is really helpful actually probably better than my last instructor. Thanks a bunch!
Ray Isaac I was just kidding Ray. If you are really interested in learning to be a mobile crane operator, you really need to go to a crane school. Look up ATS crane school in Wisconsin.
curious could one uses 2 cranes to lift the something one sling on one crane and just do out the sling calculations Fsin(theta) or just canceling out rope forces to get a load to be lifted safely with to crane each of which exceeds the capacity of any one crane restricted to a certain load radius under construction restrictions
I've always used the load chart for my crane when setting up my job because we take up a lot of the job site ,I determine where my pin point would be in the area given to us ,then use the machines load chart to tell a site superintendent if the area he's given us will allow the crane to pick the weights I need from my material piles .
James Whitfield in the situation I was speaking of having my cranes location picked by others I take my pin point where the machine is supposed to be set up ,determine my heaviest load ,the boom angle etc and calculate weather I'm being given a shit set up area before I even pull the crane in .
O if you get the jib or boom uses the smaller weight for the max or you potentially have structural problems of it breaking if the jib is less strong them the boom and if the boom is more strong then the jib you have tiping capacity
I would imagine the max weight a crane could carry would be if it was straight over head if you move out farther you lose the amount of weight you can lift because of leverage issues which are easy to calculate using torque / moments calculations but this chart gives a frame of reference of how much tons/lbs we are talking about at certain load radius / angles
Sir what is the formula of boom Angle using only the calculator,, for example 36 meters radius and 68 meters boom length ,, sir please tell me how to compute it using only calculator
Great instruction. Alas the video was frustrating because the operator discovered the zoom button. This would be much better for learning, and much less distracting, if you set the video camera on a tripod and just let it run.
Can anyone tell me how to calculate load radius ? He said that , we will get it from load chart. But how ? I don't know angle and boom length !!!! I jus know only dimensions of load
