Specification of our tower crane:
- Q: how to pass a crane practical test?
- Practice make perfect.
- Q: What do you do after you made 1000 paper cranes. I know you string them up, but storing them is hard. Do you ceremoniously burn them or what? When can they be gone? This is the missing link in the story I want to know. I have 846 and I want to know what to do after I'm done.
- i know this big organisation in Japan and some of my frineds live there... if you are interested, I can give you the address and more details...etc
- Q: What time period would you consider that Stephen Crane wrote in? I have no idea. By time period, I mean like the kind of writing from those times. Ex: Renaissance Period.
- Crane was from the late Victorian era, timewise. His prose writing was American realism or naturalism, but his poetry was more modernistic. The Edwardian era began just after his death in 1900. Although his most famous work was The Red Badge of Courage, he was not even born during the Civil War.
- Q: I have always wondered how they get cranes off the top of huge buildings when they finish building them.I have had many people tell me how they THINK the cranes are taken off. But I want to know for sure. Can anyone give me some evidence? A web site or something??When I say big building I mean like 100 storeys.I have been told things ranging from a helicopter takes them offToThey build tracks down the side of the building and drive it downAndThey pull it to pieces and take it down the elevator.These MAY be real but sound like wild guesses to me.So does anyone know the answer?
- but never have I seen a set of tracks or elevator used...not to say that it isn't possible but I have only worked big buildings in NYC...maybe things are done differently elsewhere in the world
- Q: How much more than m of tower crane jib winch point height should be equipped with anemometer
- According to the regulations of JGJ196-2010 for the safety and safety of installation, use and disassembly of tower cranes for construction purposes:The use of 4.0.15 tower crane height of more than 30m should be equipped with obstacle lights, jib root hinge height of more than 50m should be equipped with anemometer.
- Q: In the case of tower crane operation, the operation should be stopped
- In case of six or more gales, heavy rain, heavy fog, heavy snow or tower crane, you should stop working
- 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: First Summary gets best answer...thanks!
- The City is covering itself by shifting the blame form a negligent city inspector to the crane company by charging its owner with Manslaughter Charges. This is typical of civil service personal who forget who they work for (We the People).
- Q: A heavy concrete panel is being lifted into position in a building by means of a crane (see figure below). The tension of 1.78 x 10^4 N in the supporting cable produces a torque with respect to point O. (Let L = 46.3 m.)
- The crane contributes a torque of 495,979.8 Newton-meters. 1.78e+4 * 46.3 * cos(53.0) = 495,979.8 ...but this is not the total (net) torque. There is also a torque due to the weight of the concrete slab - torque we are ignoring since we do not know the weight of the slab.
- Q: Two Cranes have been sitting on nest for about 50 days. Will these 2 eggs hatch. They will not leave. It is their 3 Clutch. The first one resulted in a baby colt, but it got hit by car. The second never hatched.
- What species of crane? Sandhill cranes have an incubation time of around 30 days, do you know the exact day of egg laying? Are you sure they haven't hatched and they are sitting on chicks? If you are getting close enough to the nest to see eggs or chicks, you might be too close and could be interfering with their natural behavior, unless they are captive or you are using a blind. You mentioned their chick being hit by a car, so if they are nesting that close to people, they may be nervous and are flushed from the nest too often to keep the eggs the right temperature. It's hard to say without more information. Edit: Extra cold weather can damage the eggs. It does seem like they've lost this clutch-50 days is long past when they should have hatched. They may be trying to incubate them anyway, I haven't worked directly with sandhills, but other birds that I've conducted nest monitoring studies on have sometimes sat on nests a while past when the eggs should have hatched. Hopefully this is actually their fourth clutch and you missed the removal of the third clutch. Good luck!
