Q:OMG! a phoba of crane flys, and there are 5 on my celling right now!!! What do I do, will the move and fly around eventually? I can't kill them, they are out of my reach, and if they start moving, im runing the %^$ outta my house.Will they die by tommorow? or will they just hang there?: dude they aren't even harmful... they wont die by tommorrow but they'll move eventually so you could smack them then

Q:What kind of bodies are tower cranes made of?: Tower crane is composed of three parts: working mechanism, metal structure and power unit, and control system. The composition and function of the three parts are outlined below.

Q:is the elevation of the upper surface of the tower crane foundation flat with the elevation of the bottom of the new building? Or lower than the trough bottom elevation? ThirtyI think this is better. Please specify which specification has the relevant regulations. Which page is it? Thank you very much！: There is no standard in the tower crane foundation and building foundation, there is no such provisions.In fact, you can do whatever you can. The only factor that can be said is the Design Institute, to see if they agree.Design Institute to consider this problem, generally disagree, you let the two based on the surface flat, because there is a stress concentration problems. It's like a pebble under your mattress. So, in general they will demand based on the surface in the construction of tower crane foundation floor, the middle 30-50cm gap with soil pad.Of course, no matter which of these two methods you have to use the back belt to enclose the tower crane foundation.

Q:What is the wall radius of a qtz50 tower crane?: The working radius is usually 50 meters. There are also 48, 49 meters. For example, 4810, 4910, and 5010, belong to 50 tons of tower cranes.Qtz50 resolves to:Q: crane;T: Tower type;Z: Jack up;50: lifting torque of 50 tons meters.

Q:↑ pretty much explains itself. (:~Animal_Lover: Probably okorder /

Q:How do you win something from those crane machines in stores?????: Spongebob says to Squidward, Be the crane. Holding the button until it releases to the door, don't letting go of the button helps me win something, don't let the time run out, look for a place where the claw can hook up to something like an attachment or box . Sometimes it is pure luck. I won about 600 different things from jewrly, watches, stuffed animals, precious moments porcelain boxes, rings, landyards, and collectibles. Sometimes double or triple at one time. Good luck!!!!

Q:Exactlly what type of bird is a crane?: Crane (bird) From Wikipedia, the free encyclopedia Jump to: navigation, search Cranes Indian Sarus Crane Gruzs antigone antigone Scientific classification Kingdom: Animalia Phylum: Chordata Class: Aves Order: Gruiformes Family: Gruidae Vigors, 1825 Genera Grus Anthropoides Balearica Bugeranus Cranes are large, long-legged and long-necked birds of the order Gruiformes, and family Gruidae. Unlike the similar-looking but unrelated herons, cranes fly with necks outstretched, not pulled back. Most have elaborate and noisy courting displays or dances. While folklore often states that cranes mate for life, recent scientific research indicates that these birds do change mates over the course of their (considerable) lifetimes (Hayes 2005). Some species and/or populations of cranes migrate over long distances, while some do not migrate at all. Cranes are gregarious, forming large flocks where their numbers are sufficient. Most species of cranes are at least threatened, if not critically endangered, within their range. The plight of the Whooping Cranes of North America inspired some of the first US legislation to protect endangered species. They are opportunistic feeders that change their diet according to the season and their own nutrient requirements. They eat a range of items from suitably sized small rodents, fish, amphibians, and insects, to grain, berries, and plants. (The cranberry is so-named for its flowers' resemblence to the neck and head of the crane.) There are representatives of this group on all the continents except Antarctica and South America.

Q:the way u find them climbing with the building makes me wonder how they become this long and what is the mechanism for that: *Tower okorder /

Q:This has nothing to do with travel, I'm just curious. I hate it when the news doesn't follow up on stories they focused on earlier. Does anyone have a status update on that crane that was swaying in the wind during Sandy?: My friend, that is a good question. According to the latest news conference from the Mayor, the crane's boom arm is secured to the structure. However, West 57th Street between Broadway and 7th Avenue is closed until farther noticed. In addition, the 57th Street-7th Avenue subway station on the N, R and Q Line is closed and trains are bypassing the station in both directions, according to the MTA. Good luck Native New Yorker

Q:What did Stephen crane contribute to history?: I think his greatest contribution was The Red Badge of Courage. It was the most ealistic portrayal of a Civil War soldier written at the time; so real, in fact, that veterans swore the had fought alongside him during battle (Crane wasn't even alive during the war).
