Q: I am currently in the Air Force reserves as a heavy equipment operator. I really want to learn how to become a tower crane operator. How would I go about doing this? I live in CA.: Hey Patrick, I was formerly a tower crane erector out of Washington DC. BUt, to yor question, I wold highly recommend you go to your town's Operator engineers Union Hall and inquire as to the qualifications and requirements to enroll in their apprenticeship program. Yes you will have to go thru the apprenticeship program. A tower crane operator is a coveted job among operators... You have to learn to hold your 'P for long periods as well as have great depth perception You coming out of the service, you should be given some preference Good luck

Q: Safety rules for tower cranes: Three. Check after shutdown3.1 after the tower crane has stopped operation, it is necessary to select the suitable position of the barrier and the middle of the track when the turret is turned and the arm to stop along the wind, and then lock all the rail clamps.All 3.2 tower crane rotary mechanism with a normally closed or braking device, in the stop after the operation, the driver must remove the handle, release the brake for crane in the wind blowing in under the direction of rotation.3.3, the hook should be lifted to the minimum distance from the lifting wall, not more than 5m position, hanging on the hook is strictly prohibited. Not to take reliable measures, not by any means, limiting the boom rotate with the wind.

Q: What are the three different types of Cranes?: A very good information is provided so far thanks . i read on many sites but the content on this site is very good. i like to read about cranes and i have also many cranes actually i see many people did same thing he takes

Q: my class is supposed to start reading poems/short stories by Stephen Crane.why should i look forward to his work?: Well, you know he lived in the late 1800s, so you probably have an idea of what his poetry will sound like. Then you read some of it, and the effect is sort of like walking into what you think is going to be a prissy hair salon and being whacked over the head with a bunch of bananas wielded by a glow-in-the-dark green monkey from Jupiter. Crane's stuff is that weird. And I mean that in a good way.

Q: ok, so if chad is a crane then why doesnt he stay in the mansion? he is a crane right?: Chad IS a Crane... he IS Alastair's son with Liz (Eve's adopted sister) so YES he IS a Crane but he is not the long lost son of julian and Eve ...Chad is Julian and Sheridan and Beth's Half Brother ( remember Beth was also proven to be Alastair's daughter) and I do not know why he doesn't live there ? It is weird everyone else lives there why not them too?

Q: I am 15 years old and into urban exploration. The only thing I haven t done yet is climb a crane. I don t want a big lecture on the dangers because I am fully aware of how dangerous it is and am also fully confident in my abilities. I am also ready to take full responsibility if I were caught. Although I know its Illegal, I don t know how Illegal it is and I would like to know the following...1. Will Crane Climbing get me charged with criminal trespassing?2. Will I get time in Juvenile?3. Is it possible that I could accidentally activate/deactivate something that would endanger the workers?4. What would happen if a worker got ahold of me?And again I feel like I need to mention that I don t want a Bull **** lecture on it not being safe. :): Just do it. It will be great, just like in assassins creed. There will totally be a hay bail waiting for you. Don't worry about the law when you jump.

Q: I'm 17 and I was planning on reading it for class, do you think it will be easy to read?: Stephen Crane, Maggie is fantastic! I read it in school when I was 14 so I have no doubt you will have no problems in reading it. Maggie is the tale of an inevitable fall from grace on the part of a young, innocent girl trapped in the vicious world of New York City's slums. Yearning for acceptance and love, beaten at home by alcoholic parents, Maggie sets out with Pete, a local bartender whose cultured mannerisms elicit great respect from the impressionable young girl. However, when Pete spurns her for another, Maggie is ejected out onto the street, forced into prostitution to make a living. We last see her moving off, a huge, oily fat man in tow, for a darkened corner in the city's seedy underworld. If Upton Sinclair's The Jungle is a torrent of social anger and protest, Crane's Maggie is like a brilliant lightning strike, flashing across our vision and leaving us temporarily blinded. The book--scarcely 70 pages--is succint, brutish, and merciless. Crane allows his readers to form their own opinions regarding the characters. His innovative use of near-phonetic spelling to depict in the reader's ear the local dialect of New York's rough neighborhoods was shocking and difficult to comprehend when the book was first released. It lends Maggie an air of earthy legitimacy. Ultimately, Maggie is a cry for the plight of poor children--the souls we overlook with a callous unease mirrored in Pete's offhand, uncaring rejection of young Maggie's genuine love and affection. It is, without qualification, Stephen Crane's greatest and most moving achievement.

Q: explain thoroughly please: Sure. Let's say that a crane needs to hoist a load of 10 tons, and that because it needs to reach over some obstacles, needs to lift at a horizontal distance of 50 feet away. That creates a torque about the base of the crane of 500 ton·ft. By positioning a counterweight on the opposite side of the tower, the magnitude of the moment can be mitigated. For instance, let's say a counterweight of 10 tons is positioned at 25 ft on the other side of the tower. The moment produced by the counterweight is 250 ton·ft, so the net moment at the base is 250 ton·ft. Furthermore, when the 10 ton load is positioned and release, there is still a 250 ton·ft moment at the base of the tower; it has simply switched direction (say from rotating the crane to the right, to rotating it to the left). If you find this helpful, please award Best Answer!

Q: I swear I'm a giant crane fly magnet and whenever there are crane flies within a mile of me they'll find me and chase me, and I'm dead terrified of them. I noticed that there are more and more of them since the beginning of April. Does it have anything to do with the rain? When will they go away?: I'm sure they are nothing to be afraid of. Despite their common names, crane flies do not prey on mosquitoes as adults, nor do they bite humans. You have a higher chance of being stung by a bee than being bitten by a crane fly. Just think of them a different way. Just think they are regular flies. Crane flies are a food source for many birds. They are also susceptible to fungal infections and are a food source for many other insects. Try getting a bird if you want to. :]
