Main Features of Tower Crane

 

1) This kind of crane adopts standard section hydraulic lifting and connecting.The max. height can reach 180m with wall tie ins.

 

2) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.


3)The range-change structure drives the trolley moving on the horizontal crang jib, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.

 

4) The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation. The crane is equipped with lifting height limiter, trolley ranging limiter, moment limiter, weight limiter etc..

 

5)The cranehas scientific layout and handsome appearance. The drivers cab is set independently on one side, with good vision field. It creates a good working environment for the operator.

Q: Do you find it ironic a crane crashed into Mecca's holiest mosque on 9/11?

Q: Write a fully developed paragraph that contrasts the effects of war in two of the following works: Cranes, Thoughts of Hanoi, and Tokyo.
I could not find Tokyo on the internet...I will look for it later because the first two selections were so good. I did find and read Cranes and Thoughts of Hanoi. The thing that struck me most was that they both had in the back of their minds, in their memories, the thoughts of childhood in their home countries, all its mysteries and beauties...and as well all the regular, daily life going-ons of the communities. It was all still alive to them in their mind, and indeed, in real life. Those same trees they climbed as children still grew. farmers still grew crops. Birds were still birds, wild and free, or caught and sold. War is so awful, so much death, I think you are astonished to find that life still goes on. Much changes yet much remains unchanged. The great wheel of life turns.
Q: Who do you think was better and who would've won if they faced.
Having seen both in various video clips, I would have to lean towards Irving Crane. Crane was winning world championships from his twenties well into his sixties. Yes, Mosconi has more records and world titles to his name, but most historians agree that his 526 ball run was performed on a 4' x 8' table, which would not have been considered professional conditions. I'm not taking anything away from Mosconi. Crane was a far better defensive player. Personally, I would have liked to have seen Ralph Greenleaf in his prime. So little video footage is available from those years unfortunately. Very good question.
Q: Thanks to anyone who helps ^^

Q: the question is :Two cranes can unload a ship together in 15 hours. The faster crane takes 16 hours less than the slower crane, if each were to unload the same ship alone. How long doesi t take for each crane to unload this ship? I done most of the math but i am stuck with this last part .15+- radical 1185/2
No. of hours for the slower to unload alone—x: 1/x + 1/(x - 16) = 1/15 (x - 16 + x)/(x? - 16x) = 1/15 15(2x - 16) = x? - 16x 30x - 240 = x? - 16x x? - 46x = - 240 x? - 23x = - 240 + (- 23)? x? - 23x = - 240 + 529 (x - 23)? = 289 x - 23 = 17 x = 40 No. of hours for the faster to unload alone: = 40 - 16 = 24 Answer: slower crane, 40 hrs; faster crane, 24 hrs Check: = 15(1/40 + 1/24) = 15([3 + 5]/120) = 15(8/120) = 15(1/15) = 15/15 or 1
Q: Hi,I am looking for study for Design, Calculation and selection of Overhead Crane supporting Columns. (Not the Crane runner way beams ) Could you please suggest me the suitable references on internet?Thank You !
See okorder /
Q: how do you win at the crane game?
im the master of the crane game. You gotta scope out the animal first! If it looks heavy then dont even bother. Whenever you grab hold of something its gonna pull it up and shake when it hits the top right? Thats why you go for something close to the hole it drops in. They have one where I work so I lock the wheels, grab the animal and pull the whole machine forward so that it just falls in the hole lol.
Q: I need to do a report about Stephen Crane, answering the question how did his life affect his how he wrote his books, does anyone know?
Crane is noted for his early employment of naturalism, a literary style in which characters face realistically portrayed and often bleak circumstances, but Crane emphasized impressionistic imagery and biblical symbolism rather than graphic realism. Crane's realism, writes William Peden, is often more impressionistic than photographic; his interest in psychological probing, his innovations in technique and style, and his use of imagery, paradox and symbolism give much of his best work a romantic rather than a naturalistic quality. Both realism and symbolism, the two major directions of modern fiction, have their American beginnings in Crane's work.
Q: Hi,what are crane swivels and fishing swivels. are they same
