Q:The mobile crane has a weight of 116kip and center of gravity at G1; the boom has a weight of 29kip and center?
Smallest Crane
Q:how do cranes get assembled ? on building sites?
They use hydraulic mobile cranes, (they're telescopic). I watched a crane being disassembled on a building site near my home. How did they do it before they had these mobile cranes? In Switzerland, in places where there are no roads they use helicopters.
Q:how do you make an electromagnet crane?
Well I guess you would need a big electromagnet, a large power source and a crane. You would need to wind a huge coil around an iron bar, feed it with lots of direct current and stick it on a crane.
Q:what are the effects of fiction in cranes?
Huh? Cranes like the bird or like the construction equipment?
Q:What is The Decemberists song, The Crane's Wife, about?
I found this on wikipedia. The Crane Wife is an old Japanese tale. While there are many variations of the tale, a common version is that a poor man finds an injured crane on his doorstep (or outside with an arrow in it), takes it in and nurses it back to health. After he releases the crane, a woman appears at his doorstep with whom he falls in love and marries. Because they need money, his wife offers to weave wondrous clothes out of silk that they can sell at the market, but only if he agrees never to watch her making them. They begin to sell them and live a comfortable life, but he soon makes her weave them more and more. Oblivious to his wife's diminishing health, his greed increases. He eventually peeks in to see what she is doing to make the silk she weaves so desirable. He is shocked to discover that at the loom is a crane plucking feathers from her own body and weaving them into the loom. The crane, seeing him, flies away and never returns.
Q:Are tower cranes the same as tower cranes?
Tomato, you tomato, potatoes, you potatoTalent exchange of tower crane and tower crane
Q:A crane uses 2 kW to raise a 100-kg box 20 meters. How much time does it take?
We start using by defining mechanical Power: = P=Work/time What is the work here? We lift the box a given distance. Work=mgh Since we know the power of the crane, we can simply plug in the values and solve for t: t=mgh/P This is only true if the crane has a constant power, which seems to be the case LeSmartOne
Q:does it really take a crane to build a crane?
No. They are lifted into place in sections by one or more other cranes, the telescopic arm kind, which are either in a nearby street or on the building site. I watched several being built and then dismantled over a period of three years at a large development across the street from my house. However, I saw a TV programme about how they built one on top of a mountain, and there they used helicopters to lower the sections into place.

Q:can anyone give me some info on how to become a crane operator?
I am sorry I do not know where are you from as different country might have different requirement on getting a Crane Operator licence. Anyway, I believe the basic is the same: You need to attend a theory class on crane operations which usually include topics like design theory of cranes, slinging and lifting, signalling. After this, there will be a practical session to test your understanding and practical operations on an actual crane in the training center's facility. Good Luck and May You Attain You Dream :)
