Q:what attracts Crane flys?
they might be breeding somewhere close near your window. Check for magets which turn into flys and spray some raid out there. Get a screen on your window and get rid of any food or drink that they mind want you to share with them.
Q:for example, if the crane boom lenght is 40 and radius is 11 meter,the how to know about the angle.?
Boy! You really need to get the angle indicator fixed and calibrated! There are ways to estimate, but they are inaccurate and therefore not safe, if you have not got the expierence to do it. Don't use the crane for any load close to your SWL!!! An addition: unless you want to measure your reach, i.e. the distance from the crane pedestool to your load, then you can calculate the angle, but you don't need to anymore as you now know what the distance of your lift is and therefore you can look up the SWL on your chart. Get it fixed.
Q:How do they get construction cranes on the top of buildings?
With more massive cranes. Sometimes, they will put them up in pieces - and assemble them on top of the building.
Q:THE LOST LANGUAGE OF CRANES ( BOOK - FREE )?
The Lost Language of Cranes is a novel by David Leavitt, first published in 1986. So the author wasn't thinking about ebooks back then and never signed a contract to make ebooks. See if your public library has a copy in paper. Amazon sells it in paperback and hardcover. Anyone that has a copy for free has stolen intellectual property and is cheating the author and publisher.
Q:what are the materials and steps for making an electromagnetic crane?
I am assuming you mean a low power, miniature crane. You will want to wrap a iron object (a nail should work for light objects) in electrical wiring, the more times the better. Make sure you have a long length of wire after wrapping it around the iron object. Now, attach a rope to the iron object, this will be used to raise and lower it. The length of the rope has to be less than the length of the wires. Now, inside the crane have a battery. The stronger the battery, the stronger the electromagnet. Now, after connecting one of the wires to the battery, connect another one to a switch, then connect then switch with more wiring to the battery. This will turn the crane's claw on and off. The next part is up to you. If you want to be able to raise and lower the magnet, attach the rope to an axel and spin the axel to raise or lower the magnet. If you want to turn the crane, you need to place the arm on a swivel axis. Finally, to bring the magnet closer or farther, you will need a way to raise the arm, bringing the tip of the arm closer to above the center of the crane. I suggest you google some picture of cranes to understand this better.

Q:Did the popularity of the Karate Kid basically ruin the effectiveness of the crane kick?
Very few people have any idea whatsoever how the crane kick is applied. It is no way portrayed accurately in the movie. Anyone in the world with any modicum of common sense should be able to figure out intuitively you don't just stand on one leg and wait for some one to get close enough to hit. The crane kick has several applications and they are all in motion during specific sets of circumstances. I see no reason to start educating the world on how crane kicks are actually applied. If you want to learn go find a White Crane style instructor.
Q:What is the insulation resistance of tower crane?
Two. Safety regulations for tower cranes GB 5144 - 20068.1.3 tower crane metal structure, track, all electrical equipment metal shell, metal line pipe, safety lighting transformer, low voltage side should be reliable grounding, grounding resistance is not more than 4 ohms. Repeated earthing resistance is not greater than l0. The selection and installation of the earthing device shall comply with the relevant requirements of the electrical safety.The insulation resistance of the 8.1.7 main circuit and control circuit shall not be less than 0.5M ohm.
Q:Can anyone summarize this article for me its about Manslaughter Charges Expected in Crane Collapse?
Manslaughter charges come about when it involves death, caused by negligence on someone's part - either the operator, the owner of the crane, the contract, etc.
Q:how do calculate Gear box toque & speed in EOT crane?
Your okorder.com/... contact them with your enquiry. You must include Model and anticipated loads as that determines torque applied. Seed is operator dependent for safe operation.
