 TOWER CRANE TC3807 speed regulation by frequency control

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:What Japanese counter word is used for multiple origami objects...such as 1000 cranes?
1,000 cranes is counted using the bird counter (there's one specifically for birds or rabbits) so it's sen-ba-tsuru. It would depend on what you've made in origami. The most general counter would probably be -ko. one origami work ikko two niko three sanko four yonko five goko six rokko seven nanako eight hakko nine kyuuko ten jikko I think you could use it for almost anything that you could make in origami, though, (like senbatsuru) there could be a more specific counter to use depending on what you made, but there are so many counter words. If it's something flat, or you wanted to count origami paper, then it's -mai If it's a long slender work of origami -hon
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:What kind of flower is the Sunset Crane?
Okay, i'm going to get every backyard gardener east of denver jumping down my throat on this one, but it's time you all wake up and know the real name of one of your favorate potted plants. only then will you beleave me when i tell you the sunset crane is a type of geranium. the true geranium. not the plant most people know as the geranium is botanically Pelargonium. that silly looking, red flowered, fuzzy leafed thing everyone loves to stick in a pot by their front door every summer back east and mistakenly call a geranium is not really a geranium. even the fancy Martha Washington geranium is not a geranium. it is the Martha Washington Pelargonium. but whats the use? unless you are a botanist everybody back east is going to say i'm just another fruit cake from california. (born and raised in wisconsin i'd like to add) okay, your sunset crane is botanically a geranium, often called by it's common name cranesbill. okay, you have the real best answer, so go ahead and pick the wrong best answer from some smuck from back east who knows best. sure i have two post graduate degrees in science, been a univ certified master gardener for over 15 years and just might know a tad bit more then the eastern fair weather, summer time gardener. but don't let that prevent you from thinking i'm nuts and choosing a better, best answer. i'm used to it. grandma is always right... until her plant dies. then they call me for the real low down.
Q:Like those huge cranes on the top of buildings that are being constructed - how do they get them up there???
They erect it from the bottom and work their way up. The crane is also connected to the building at specific intervals. The larger cranes require a footing to be placed that can be as large or even larger than the building footings. The cranes are disassembled in the reverse order. The top piece is taken off and lowered. Cheers and good luck.
Q:How to build a strong paper crane?
Fact: paper is relatively strong when you pull on it, but when you push on it, it easily crumples. Build your crane out of several bars. Bars that are being pushed upon by the weight need to resist the crumpling. A good way to do this is to roll a sheet of paper into a tube form to make the bars. Bars that are only being pulled on don't need to be more than a sheet of paper. A frame cranes are simple to make: www.lni.wa /wisha/rules/generalsafety/images/24_d2_a-frame.gif
Q:What is the Tower crane Roadb track laying criteria?????????
The okorder ) track in the vertical and horizontal direction is not more than 1 / 1000. (we Should use the standard instrument, two tracks, and keep in10m range ,Measuring not less than 3 periods, respectively,taking the average).
Q:I'm making 1000 origami paper cranes. I started 2 days ago and have 135 done so far but I was wondering what do to with it after. I don't want to just make them and have them sit in my room forever.
Well if you don't want to keep them you can look up organizations that wish to use them for a project. There are a lot for Japan, one that was organized recently for the tsunami was accepting cranes for a fundraiser (every crane sent in earned a certain amount of money with the finished collection being placed in an art museum). I know some hospitals accept cranes for the children's ward, that is what my class did in elementary school we made 1000 and the hospital used them as decorations for the Christmas tree. Then there are individual projects that people start online with which they are accepting cranes to fulfill the one thousand mark for people they know who are sick etc. (relates to the story behind the 1000 paper cranes practice). As a side note if you contact the organization you find a lot of the time the shipping is prepaid you just have to drop them off at the post office. Hope this helps.
Q:Is Fireplace Crane a modern term for the swing-out metal arms that hang over a fireplace for cooking? e.g. like in dutch ovens or pots/cauldrons that hang over a fire.It sounds like a more modern term and I need to know if there is an older term. Thanks.
I can't think of older terms at the moment, but definitely 'fireplace crane' sounds modern, and possibly American, to me. In Britain I have never heard the term, not in any historical or modern setting. My idea of a crane is a big item at a dockside or on a big building site. A domestic hearth or kitchen is too nice a place to have a 'crane'!
Q:What makes a crane so strong?
Cranes are built using a structural technique called a truss which is characterized by looking like a series of triangles connected together. That structure prevents the members from having to resist any bending loads. All of the truss members experience only tension and compression, no bending. That is an extremely efficient structure which is why they can be so strong without being monstrously heavy. Or if you prefer the short answer, engineers make the crane so strong.
