Q: They seem to be the tallest thing around, so what put them up?
They are self-elevating. They jack themselves up. It was the invention of the self-elevating crane and the self service elevator which made popular tall buildings. In older cities, such as Paris, the height of a building was limits by the number of flights of stairs people were willing to climb.
Q: All types of jack up cranes. How is the maximum lifting torque converted?
Tower crane lifting torque = crane maximum lifting weight * maximum operating range; for example: the maximum lifting weight is 2T*, the maximum operating range of 50 meters =1000KN.m.
Q: I am currently in the Air Force reserves as a heavy equipment operator. I really want to learn how to become a tower crane operator. How would I go about doing this? I live in CA.
Hey Patrick, I was formerly a tower crane erector out of Washington DC. BUt, to yor question, I wold highly recommend you go to your town's Operator engineers Union Hall and inquire as to the qualifications and requirements to enroll in their apprenticeship program. Yes you will have to go thru the apprenticeship program. A tower crane operator is a coveted job among operators... You have to learn to hold your 'P for long periods as well as have great depth perception You coming out of the service, you should be given some preference Good luck
Q: Tower crane technical condition GB/T 9462-1999 has been cancelled? If so, what is the new standard?
This standard applies to tower cranes defined in GB/T 6974.3.This standard does not apply to mobile cranes equipped with tower cranes. This standard compares with the 5 standards such as GB/T 9462-1999, the main change is as follows:- redefining the type identification principle of tower cranes and eliminating the parameter series in JG/T 5037-1993;
Q: I've always been puzzled how cranes operate.Because as buildings get taller so do cranes but i don't know how they increase the height of the cranes.Can you help answer this please?
search for others, animation and video of process more edit Some cranes actually climb the structure of the building and are taken apart when the building reaches its full height.
Q: What qualifications do you need to be a Crane Operator in QLD, Australia?
You need to do a specific amount of hours in training to be a crane operator in Australia, I know that in Sydney, you are certified by the WorkCover Authority, or that's how it was many yeas back. Special emphasis is on loads, and point of load. We do not need a mobile crane tipping over do we. Safety, working near electrical, and on soft ground. Weight you can extend to on a jib. etc.
Q: A crane lifts a 2355 N bucket containing 1.81 m3 of soil (density=2084 kg/m3) to a height of 7.56 m. Calculate the work the crane performs.
W=Fdcos(angle) W=mgh=2355(7.56)=17803.8 J
Q: What is the Tower crane Roadb track laying criteria?????????
The okorder ) track in the vertical and horizontal direction is not more than 1 / 1000. (we Should use the standard instrument, two tracks, and keep in10m range ,Measuring not less than 3 periods, respectively,taking the average).
Q: Protected cranes are nesting in pine trees with possible disease carrying bird droppings covering drive way and street where neighborhood children play. I've called several local organizations only to be told there is nothing I can do since they are protected by law. These birds return every year and stay for about 4 months - each year gets worse with droppings and stench. Daily cleaning is required but that still does not keep the areas around them clean.
If the pine trees have been designated as a protected breeding site, you may well be SOL. The reason these critters are protected is that they have had their available breeding habitat swallowed up and plowed under by stupid humans who insist on putting their homes where they don't belong. Since their life depends on using that site, and your's doesn't, the birds take precedent. However, if the site itself is not protected, and only the birds during nesting season, then when the birds move away for the season, simply remove the pine trees - their habitat will be gone, but the birds will still be alive, and they can find new nesting ground. But since every crane species I know of builds their nests low to the ground or floating in marshland environments, I seriously doubt that whatever is nesting in your pine tree is actually a crane. Even the demoiselle crane of central Asia builds its nests low to the ground, but in desert scrub/plains rather than wetlands. So perhaps if you get the birds properly identified, you'll have better luck taking care of your problem.
Q: and it appears to be looking up at the sky?
I think that refers to the term: Deer in the headlights It probably saw the light, looked up, and then got knocked out so that it's neck was still craned up when it was dead.
