- Q:With hi-rise buildings being constructed left and right, i was just wondering, how do they raise cranes? this has really been bugging me for a time now..
- I think you mean tower cranes, you will notice on these cranes that there is small size pieces and on larger piece with hydraulic jack, when they want to extend the crane , they insert the smaller size piece into the large piece and push up the upper part to insert the new piece and so on. There is also another type of cranes which is the climbing type, they are almost using the same principle but lifting up the crane it self using the concrete shaft
- Q:I was wondering if Steam Cranes are still used to clear train derailments or are the all mothballed now? What do they use to clear derailments now days if the not the Steam Cranes? Also way are there 2 types of hooks on the crane anyway? Thanks
- No, they don't. They have to use road cranes - think of the accident at Grayrigg some while back. They had terrible trouble clearing the line as heavy lifting equipment had to be brought quite a distance over muddy fields. I seem to remember special temporary roads had to be laid. Similarly with the freight accident in Scotland a few weeks back, roads were closed, again whilst wreckage was cleared.
- Q:It's better if the explanation is not complicated.TQ
- Hello, 1. Modularity: You can build ships (larger ships) in modular sections and have the crane lift these modular sections and put them into place for final assembly. This is one major advantage that was not available back in the day
- Q:what is the function of load indicator on a crane?
- Two things, The maximum lift and the maximum extension of the boom. The maximum lift is based on weight and structural considerations and the maximum extension of the boom prevents the crane from turning over. The weights on the back of the crane is prevent the crane from turning over. TexMav
- Q:I would like to get some advice from Martial artists of the training that Crane style Kung Fu go trough especially the balance. I would like to learn how they learn to balance without difficulty and the training they go trough.
- Balance is balance - there's no specific training but good balance will help you with all aspects of your training. A few things that helped me - tying shoelaces by getting into a crane posture rather than kneeling to the laces. The concentration on the shoe helps to balance you. Practice Crane Stance and try to keep a clear mind while in the stance - if you start worrying then you'll fall. Remember to keep the knee high and the foot pointed.
- Q:If so, would you mind finding me a site that will teach me how to either with a good video or an easy-to-follow explanation because i tried many sites and i just cannot understand clearly enough. I get so far and then i can't tell what is happening in a step, and i can't do it.If you wouldn't mind to find me a site that you know will help, since you can make them, it would be greatly appreciated.Thanks.

- 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:who invented cranes?
- Lost in the mists of time. We know that the Babylonians and Egyptians used simple cranes a few thousand years BC.
- Q:I was wondering if this is possible. The wall we have designed is very close to an existing retaining wall. In order to properly form and waterproof the wall we would have to demo that existing retaining wall. My idea was to build it off site, waterproof it, and then crane it into its location. Is this possible? any similar methods? thanks
- If you use precast concrete sections it can be done. You can even have a decorative side if that is required. You might need to have some form of interlocking connections to tie the whole thing together. Depending on its height there might also be a need for anchors to keep it from trying to tip. Without more very detailed information it is difficult to really answer this question. As an example: depending on the type of soil and the height of the wall it is possible to remove the existing wall and install a new one in a day if you use something like a keystone system.
- Q:In the Bride comes to Yellow Sky, Stephen Crane uses symbolism to evoke in readers a sense of the “old west”. However, the knowledge of the “old west” that the average person holds in his or her mind is false and nothing more than a Hollywood created myth. By using the symbols inherent in Hollywood’s old western myth Crane manipulates the reader’s misconceptions only to leave them feeling stupid when he reveals a hole in that way of thinking with the irrational ending.This is actually a thesis i'm working on for an analytical essay on the piece.I need to know if anyone has ever read the story and gotten the same feeling Crane was having fun at the reader's expense or perhaps poking fun at the old western I have very good points from the text to support my thesis but i cannot find anything online that touches on the possability of this being a parody. Anyone else think Crane's having fun or is a bit condescending in this piece?
- I have to say no. Your question erred in a significant way. Hollywood didn't create this false image of the West. The false image was created a long time before by people living in the age of the incidents. It didn't take publishers long to notice that people living back East enjoyed these gritty depictions of the West. Dime novels were a big seller in the 18th and 19th centuries. Look at Stephen Crane. He died in 1900. Hollywood was non-existent as the facet of American life that it holds now. Crane would have been writing this story with the idea that he was depicting a real slice of the wild West that was becoming more civilized.
