Q:why does the power company use helicopters to service the repair lines instead of trucks with tall cranes?

High-tension lines operate at hundreds of thousands, or millions, of volts. At this potential, electricity can jump through several feet of air to reach a path to ground. This pretty much rules out using trucks, because it would be prohibitively expensive or impossible to build a crane out of entirely non-conductive materials. A helicopter is electrically isolated from the ground, so it's less difficult to drop a technician off and let him hang from the line itself while working. (It is still necessary for the technician to use a wand to bring the helicopter to the line's potential before starting work, because of the capacitance of the helicopter's body.) They could of course use a truck to service the lines if the power was disconnected, but the cost of shutting down service to an entire region of the country exceeds the operating cost of a helicopter.

Q:She was editing some of his writings. She was appalled(prim proper Nebraska gal) by his lack of punctuation. He said he didn't have the time for it. He was right. Shortly after he died of TB. Do you ever feel that time is your enemy; that you have only so many years to make a difference?

Q:tnx for answering :)

a young girl named found out she got leukemia from the atom bomb. while in the hospital, she met a boy who got leukemia from his mother while in the womb and she heard him being rolled out from his room when he died during the night. but even though he died, she never gave up hope. the japanese have a story that if a person folds a thousand paper cranes, then they will be granted one wish. everyone gave her paper to make the cranes but she died before she could finish so her friends finished the job for her and the petitioned to put up as statue for her and you can go see it today. unfortunately i forgot the girl's name. i haven't read the story or heard it since 4th grade

Q:I was wondering if Steam Cranes are still used to clear train derailments or are the all mothballed now? What do they use to clear derailments now days if the not the Steam Cranes? Also way are there 2 types of hooks on the crane anyway? Thanks

I am not aware of any steam cranes, they are all diesel as far as I know. the two types of hooks are for different types of pulling, one is generally for straigh lifting and the other for pulling across the ground or up an embankment where the pulling force is at somewhat of an angle to the equipment. .

Q:I saw this documentary on ancient buildings like the pyramids and it said that we don't have a construction crane that can life the stones used to build some of these ancient structures.So I gotta wonder how much the strongest crane CAN lift....or is that just fantastical nonsense about cranes not being able to lift those blocks?

First, okorder /. This means that at 5 m the capacity is 600 tonnes. Double the radius, half the capacity. A crane located at the foot of the pyramid, will be at 115.2 m from the center. At that radius, the crane could only lift 26 tonnes, so this crane could not lift the greatest stones weighing 80 tonnes. Being the boom only 100m it could'nt even reach the center.

Q:which crane makes only one Life Partner ?

Apparently, although traditionally, most cranes were thought to mate for life, recent research suggests that they do actually change partners during their lives. I don't know how extensive or how conclusive the research is, or what species it involved, but it does suggest that the folktale may not be true.

Q:Please help!

there are several kata, that was influenced by it, like niahanchin (tekki), chinto, rohai and many others

Q:Captain Kirk, TJ Hooker or Denny Crane?

Denny Crane. His acting seems more natural than the others. He is a crazy oversexed senior citizen whom everyone loves even though he frustrates the hell out of them at times. Denny Crane!!!!!! Every older man's mentor.
