Q:Can anybody explain how they assemble a tower crane. How long does it take? How?
Tower cranes assembly starts with the foundation of the crane with lot concrete blocks for fixing, then they fix the first bottom part of the crane then they fix the boom with the counter weights, when they want to extend the height, they fix a jack up machine which lift up the boom and then insert a vertical piece and so on till they reach the required height. During the first installation they use a small mobile crane and then after the crane it self lift and fix the pieces
Q:what do sand-hill cranes eat-as far as planting a food source for them?
These birds forage while walking in shallow water or in fields, sometimes probing with their bills. They are omnivorous, eating insects, aquatic plants and animals, rodents, seeds and berries. Outside of the nesting season, they forage in large flocks, often in cultivated areas. In many western states and provinces of Canada, Sandhill Cranes are hunted during waterfowl seasons. The meat is reportedly among the better-tasting gamebirds.[citation needed] The Florida subspecies is often seen in residential yards, and these birds seem little afraid of human approach. These visitors will eat shelled corn and commercially purchased bird seed from the ground and from feeders.
Q:Protective earthing resistance of tower crane
Q:Any origami site with this one? Kissing Cranes?
Now, If the guy was 75 yrs old, with beautifull gray hair and can ballroom dance, and asked If he could kiss me , I would say yes, The one thing I hate is when a guy opens his mouth over yours and thinks thats a kiss, I would have to tell him I don't need a bath. Or that I don't need to be swallowed up. If he's that hundgry he should go get something to eat at A fast food place. HA HA HA.
Q:Is it true that crane flies are THE most venomous insects in the world?
RE: Is it true that crane flies are THE most venomous insects in the world? I've heard that daddy longlegs aka crane flies contain the most deadly venom of all insects. The only reason they aren't dangerous or deadly is because they have no mouth or 'straw' to inject the venom. But I'm not sure what's correct. Although they cannot harm us humans,...
Q:Can anyone help me interpret the poem Fear by Hart Crane? or North Labrador?
Analysing Poetry Close reading may seem like a foreign and unfamiliar approach to analyzing a piece of text. However, it can often yield insights that will help you to create a unique paper developed from your own interpretation of the text. To analyze the work effectively, it is useful to concentrate on specific components of literature used to build and reveal the themes in the work. This process will help you explain how a passage relates to central themes in the text allowing you to reach an intelligent and creative thesis for a literary analysis. First, choose a passage (or a series of passages) that intrigues you.
Q:how do construction crews put up a crane?
They assemble it on a concrete foundation using a mobile crane. To grow taller, the top unit of the tower crane has a jacking mechanism that lets it raise itself up and insert another tower section.
Q:How are construction cranes extended to go higher when building skyscrapers to stay above the construction.?
The cranes are self erecting. The cranes tower is raised in sections. The lowest section is jacked up to the correct height and then a new section inserted and so on.
Q:The arm of a crane at a construction site is 17.0 m long, and it makes an angle of 13.5◦ with the horizantal.?
The easy answer is that the applied torque is the cross product of the radial arm and the force, or in this case T = 811*17*cos(13.5). The hard (it's actually not that hard) answer will depend on the design and material properties of the crane. Since the problem asks for max torque, I'd find the bending stress due to the moment found above (T = 811*17*cos(13.5)) where bending stress = Ty/I. Next, compare this to the yield stress of the crane's material and an appropriate failure criterion.
Q:please advise which type of air condition is powerful for electric crane on ship ,?
Any crane worth it's salt can take the temperature but for the operator you can do a Coleman RV Air Conditioner.
