- Q: What do you do to become a crane operator, do you go to school and how long is it?
- OK, first, what kind of crane? there are many different kinds that do many different things. From loading containers at the seaport to high rise buildings. One does not just go into cranes. The more experienced ones, started out as oilers or greasers. Some started out as signal persons. They learned by watching and listening. In the following states you must hold National certification: CA, HA,MT,OR,WA,MN,WV,NM,RI,NJ,NV,NY UT. PA and SC have restrictions now but will be added sometime soon. You can attend a crane school that prepares you for the national certification, but it expensive and not easy for someone without a background working around cranes. There is a lot of terminology and mathematics involved. Not to mention the Federal, state, local and OSHA rules you must practice. Go to your state employment office. They have all the information you need. get to know one of the counselors and pursue your dream. It is not as easy as it seems. But is it a well paying career. Good luck Bill

How long doesi t take for each crane to unload this ship? I done most of the math but i am stuck with this last part .15+- radical 1185/2
- No. of hours for the slower to unload alone—x: 1/x + 1/(x - 16) = 1/15 (x - 16 + x)/(x? - 16x) = 1/15 15(2x - 16) = x? - 16x 30x - 240 = x? - 16x x? - 46x = - 240 x? - 23x = - 240 + (- 23)? x? - 23x = - 240 + 529 (x - 23)? = 289 x - 23 = 17 x = 40 No. of hours for the faster to unload alone: = 40 - 16 = 24 Answer: slower crane, 40 hrs; faster crane, 24 hrs Check: = 15(1/40 + 1/24) = 15([3 + 5]/120) = 15(8/120) = 15(1/15) = 15/15 or 1
- Q: I am making a crane(jib) whatever you call it and I have a concept for the crane itself but not for how I will actually move the camera. I heard wires work but I can not seem to grasp teh concept.* It is a heaver camera by the way*
- On a real camera crane you would press the up and down button that moves the wrist part of it. ( I drove a forklift). If you are doing to yourself you'll have to rely on the elbow movements. I might think about renting a Genie lift. And letting someone be your hands in the thing. Unless you know how to build a fully articulating hydraulic ball-joint?
- Q: i will like to crane operator?
- You made a statement, you will like to crane (an) operator. Which operator is it you are going to like to crane? If you mean would you like to operate a crane, that is up to you. If you mean can you be a crane operator, that is up to an employer. You need to be employed as one, and that probably means training and experience before being allowed to operate cranes for him/ her.
