China Tower Crane with CE certificate for Construction

Q:Are the creators of the Karate Kid movies apologetic about the white crane defensive stance?: The movie was not a documentary, nor was it a how-to. As a result, the writers are given what's called poetic license to portray movements in any manner they wish, whether or not the techniques, philosophy, or theories behind them are accurate. I have never heard of anyone being apologetic about the movies or any of the techniques therein. But, I don't think they ought to be. The movies on both sides of the generation gap that separates them are equally entertaining.

Q:Like the tall cranes on construction sites. I mean, suddenly they're just magically there!: Yes I have. It's fascinating to watch.

Q:any kind of sayings: Whoop!

Q:A. to make everyone become a CommunistB. to become rich at the expense of othersC. to kill all the villagersD. nothing in particular: 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.

Q:Lets say you are calling to get a crane truck to lift something, and they have 3 sizes of crane trucks. 17T (with a 70 ft boom), 23T (with a 101 ft boom), and 35T (with a 115 ft boom).All they ask for is how high you are lifting your equipment, how far over, and how many pounds it is.How do you use this information to calculate which size crane is used?: I am not sure that you are giving us sufficient information. I presume that your crane truck has the boom hinged quite close to the ground, but I am sure that the specified lifting weights will not be achieved until the boom makes an angle of at least 45 degrees with the ground. The 115 foot boom will then sweep a circle of 115 x cos(45) = 81.3 feet, and lift a maximum of 115 x sin(45) = 81.3 feet above the hinge. If the boom is elevated to a 60 degree angle, the circle swept will be only 57.5 feet, but it will lift 99.5 feet. If the boom is lowered to 30 degrees, the circle swept enlarges, bt the distance lifted drops, and the weight lifting capability will also be derated. If the crane has a tower and the weight rating is for a horizontal boom, the maths are quite different.

Q:we have a project starting that will require a stack built 1km high in the air?How will they install this?: use a heavy lift helicopter, these are especially designed for this work

Q:The earthing resistance of tower crane shall not be greater than that of the tower crane: Lightning protection grounding is less than 10, transformer grounding is less than 4, special equipment requirements is less than 1

Q:will give you a wishor help your marraige succeedjust curious as to peoples thoughts?thanks lt;3 abby: no the only thing that does is make your hands sore

Q:do they start with the crane house and keep adding sections underneath it? Or do they build they tower and then somehow top it with the actual crane?: As described above, but the crane that is being used in our plant arrived in 80 semi truck loads!

Q:Captain Kirk, TJ Hooker or Denny Crane?: Denny Crane. His acting seems more natural than the others. He is a crazy oversexed senior citizen whom everyone loves even though he frustrates the hell out of them at times. Denny Crane!!!!!! Every older man's mentor.
