Q:How Much Can the Most Powerful Crane Lift?
First, okorder.com/. This means that at 5 m the capacity is 600 tonnes. Double the radius, half the capacity. A crane located at the foot of the pyramid, will be at 115.2 m from the center. At that radius, the crane could only lift 26 tonnes, so this crane could not lift the greatest stones weighing 80 tonnes. Being the boom only 100m it could'nt even reach the center.
Q:How were Railroad Steam Engines from 1830 to 1890's recovered before the advent of the Wrecker Steam Crane.?
Block and tackle. Some disassembling required. Consider this Stonewall Jackson raided Grafton WV and took several locomotives over land to a southern rail head. The special equipment was developed due to increased engine size. When steam cranes were/are used temporary tracks are laid at the wreck site for several reasons. one of which is to get equipment in and the other is to haul the wreckage out. The actual number of cranes required depended on the engine/s in the wreck, location on the wreck, skill of the operators and extent of damage. If the locomotive was damaged to much, it might be cut up. If the location was too difficult for recover, they were abandoned or buried. Rumor has it that there are several locomotives left at the bottom of slides awaiting for some one with enough money to recover them for restoration. Like the story of legend concerning a 1953 Corvette in a old barn. Hope that answers all your questions.
Q:Crane Style Kung-Fu?
No. You can make an argument that some body type may find it easier, but to say a particular style of martial art is only for one body type (tall skinny) is ridiculous. My White Crane teacher was barely 5'5 and thin, and he had no problem whipping my classmates who are in the 6' height range. Don't worry about your size. Forget the video and find a teacher. Crane is good, but so is any style that is taught by a good instructor. Besides, you are 15 and still have at least 5 more years of growth. If you start now, by the time you reach your max height, you will have been training at least 5 years and I'll bet anything your height is not going to be a concern for you.
Q:1000 paper cranes myth?
my daughter's paintings club did this for a wellness center to no longer previously...they made 1300 paper cranes and hung them from the ceiling in between the wellness center wings. i don't comprehend approximately being granted one desire, besides the fact that it made the sufferers happy and smile no count number how ill they have been. i've got heard the paper crane became into some how related with leukemia, so she made one for a chum of mine's son (he's barely 7 and has battled this ailment for 2 years) and it made him happy to comprehend that somebody who would not comprehend him could make something like that for him.
Q:Is anyone know the meaning of Chinese proverb A crane standing amidst a flock of chickens?

Q:What is your favorite poem by Hart Crane?
How about my favorite poem about Hart Crane? AT HART CRANE’S TOMB by Glenn Robert Swetman In his mind’s dark, he spoke a frivolous age where marriage of the like was spring, where vitelline worlds of virgin instinct were crushed in the obscene cleanliness of a raccoon’s paw. Did he imagine that his great sun could come trailing yellow handkerchiefs of light, like a queer comet? No, there is something out there that commands, and not worlds of perfect clipping will turn these rotund hedges into maypoles—and live. That’s why the green expands as it reaches. He must have seen this finally. His leap Into the green sea was, aesthetically, clean.
Q:Could you explain to me what's happening in the first stanza of Stephen Crane's War is Kind?
Yes, Stephen Crane talks about lost love and sacrifices in his poem. The basic casualty of war. A lover, a father and son are lost in his story and those that are left behind he tries to console. The poem is noted for the ironic use of war is kind. We all know that War is really not kind. The poem’s speaker, simultaneously sympathetic with the victims of war and cynical about the purposes of war, implicitly criticizes the image of the romantic hero, showing in graphic scenes the realities of battlefield death and the emotional torment it causes for those left behind.
Q:In the story Cranes, what was Tokchae's mission for the league?
The main idea of Cranes by Hwang Sun-Won is more of a symbolic thing; he uses different objects such as chestnuts and cigarettes, as well as the cranes in the story to convey his hope and his dream, along with his message. He is expressing the power of war, particularly civil war, which can rip apart families, neighbors and the best of friends. The story, unlike many other tragic civil war tales, is not focused on the idealogical difference btw Tok-Chae and Song-Sam. Rather, it is about the human tragedy of the Korean War. Tok-Chae and Song-Sam were ripped apart by the War. Song-Sam, on his return to his village, he finds Tok-Chae and decides to escort him to a Public Peace Police office a few miles away. On the way, he gets flashbacks and talks with Tok-Chae. These things help to change his mind and he frees Tok-Chae. This is symbolized by the two cranes which soared high into the sky. Hwang-Sun Won conveys his message effectively; unification will be achieved and is needed to repair such ties like Tok-Chae and Song-Sam. He is saying that the two cranes will fly together once more.
