- Q: dimentions of crane rail, crane beam.
- What kind of crane? There are thousands of types.
- Q: I've only read Hunger Games and watched the movie and noticed a large presence of Seneca Crane in the movie.However, I don't recall him being mentioned in the Hunger Games? Is he even mentioned in the Hunger Games? If so, please provide pages.I know he is definitely mentioned in Catching Fire but I haven't read that yet.
- Nope. He is just called The Gamemaker in The Hunger Games. I guess they wanted to elaborate on him more so that you would know Katniss's hatred for him in the Catching Fire movie.
- Q: method how to assemble tower crane?
- Generally tower cranes are self erecting. The first mast and jib sections are assembled at ground level. The mast and jib are then jacked up and another mast section inserted. If the tower crane is not self erecting then mobile cranes have to be used to assemble the crane.
- Q: What is the scrap standard of tower crane hook?
- The American Standard can provide for your reference:1, hook hanging points in the effective area of cross sectional wear more than 10%, should be disabled and scrapped.2 any visible permanent deformation and cracks shall be disabled and scrapped.3, if the wear is in the same area in two directions, it should be controlled within 5%.4, any hook opening deformation is not greater than 5%, or in accordance with the manufacturer's guidelines to determine.5, hook bow hook (i.e. intermediate position hook C shape) wear amount should be less than 5%.
- Q: I have an odd fear of construction cranes. I literally get chills and almost dizzy anytime I see cranes. I get very nervous and almost want to cry. I know this is so odd but, I've seen phobias of things that are even more odd so I wonder...is there a phobia for my fear? Does anyone else share my fear?
- Cranes were a christian analogy for saving people. The crane would be used to lift someone out of hell. So, maybe the phobia comes with the realisation that we are actually in hell and a crane won't do that much good. As far as robots, they're all bad and creations of Lucifer. The good ones are the Saints and the bad ones the devil; they're both Satan's creations who's goal is to destroy humans. Of course they work with Satan and do time travel and all that garbage.
- Q: He is one of my favorite poets. I want to read more of his work.
- 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: What are the safety devices for the horizontal arm self lifting tower cranes?
- (3) the amplitude limiting device shall be equipped with a minimum amplitude limiter and a device for preventing the boom of the boom from rebounding after the luffing of the jib. The trolley must be equipped with a trolley switch and a terminal buffer. (4) rail clamping device and walking limit device; track type tower crane must be equipped with rail clamping device. A walking limit device shall be installed at the same time. (5) a crane with wind point at the root of the boom with a height of more than 50m shall be equipped with an anemometer at the top.
- Q: The question is: A crane has a power of 500watts, and is pulling a 142kg. What is the velocity of the pulling of the crane?Please help and thanks!
- I don't remember ever doing a problem like this, but I will try to solve it. P = W/Δt, P = Fd/Δt P = Fv Force required to lift the 142 kg object; F = 142 * 9.8 F = 1391.6 N Therefore; P = Fv 500 = 1391.6*v v = 0.359 m/s So velocity of the crane is 0.359 m/s. Is that right?
- Q: What is the most amount of weight lifted by any crane?
- Buffalo Hydraulic built a crane for NASA to lift their launch pads. The heavy one weighed about 5.4 million pounds, but the crane could handle 9 million if it had to.
