Q:What are the parts of a tower crane? What are their main functions?
Jacking frame: placing slewing mechanism, when lifting tower top, bearing the weight of tower crane balance arm, main arm and tower cap.Standard section: support the weight of tower crane itself and lift the weight of heavy load, and resist the overturning moment of tower crane.Institutions include the followingLifting mechanism: lifting heavy objects.Luffing mechanism: lifting the car to change the rotation center distance.: the upper part of the slewing mechanism of tower crane (including the main arm and balance arm and tower cap) around the rotation center of rotation.Lifting mechanism: tower crane lifting, the upper part of the tower crane elevated hydraulic power system.Walking mechanism: the crane can walk on the track.OtherDrivers’ RoomElectric boxLinkage tableA foundation bearing platform or trackOther safety devices
Q:A solid answer and links would be nice.Your help and/or attempts to help are appreciated
It's actually a POST WWII story: Sadako Sasaki, a Japanese girl who developed leukemia at age eleven as a result of exposure to atomic radiation when she was two years old, began folding paper cranes in observance of a Japanese belief that the gods will grant a wish to anyone who folds 1000 cranes. Although she died a year later, her friends took up the mission, and the paper crane has become a symbol of the hope for world peace. The site below tells the story far more movingly than this summary.
Q:It seems like every time I turn on the news there is another crane collapse. I don't know if it is the same problem every time, but it seems awfully suspicious. Does anyone know why crane collapses seem so common lately? Has it always been this way?
You okorder .. This chart is not definitive, it leaves out many occupations (such as mining), it only considers fatalities (not loss of limbs, etc.) but it conveys the general picture. For hard data look at: www.bls /iif/
Q:I work in downtown Atlanta, and they are doing some kind of work on top of one of the high rise buildings downtown with a big crane. I was wondering how they got that heavy of a crane there to begin with? Thanks ahead of time!
Other big cranes?
Q:Answer please~
You know what? I thought they did but I just went through my copy again and I can't find any mention of him by name. I apologize for the incorrect answer I gave earlier.
Q:What are the safety devices for the horizontal arm self lifting tower cranes?
(6) the crane of lightning protection and anti electromagnetic wave sensing device shall be equipped with lightning protection device and anti electromagnetic drape induction measures according to the actual situation and shall be equipped with crane with a hinge height of more than 50m at the root of the boom. (7) the tower crane should be installed to prevent the rotary overload limit torque coupling (8) anti off rope device to prevent the wire rope from the working position (9) rope breaking resistant device to prevent car luffing rope break free sliding trolley (10) anti broken shaft device to prevent car car wheel shaft broken after the fall (11) brake parts that is the work device is a safety device
Q:this is a little of a random question but why do you think that we should save the crested cranes of uganda? and what do you know about the crested cranes???
Because man is a reasoning being he has the capability of saving things. It is in our nature. Secondly, if man's activities are the cause of the Crane's extinction - destroyed its habitat or food source, then man should help reverse this.
Q:I live in the upper stairs of this apartment with a huge light right next to the front door, and a bunch of Crane Flies kind of hover around it. So whenever we open the door, some of them come in, and it's a big problem. Especially to a someone like me who's deathly afraid of big bugs.So we want to buy the Raid spray, but we don't know if it would work. The Raid: Ant and Cockroach spray didn't work that well, but that's understandable.sooo anyways, has anyone tried the Flying Insect Raid on Crane flies?
Carburetor cleaner will destroy a roach instantly and costs less than Raid.
Q:I give up...Somebody who understands The Decemberists please tell me what a Crane's Wife is and what the song is about. I love the song, I sing along loudly, but I don't have a clue.
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:They seem to be the tallest thing around, so what put them up?
Large cranes are built in sections imagine like an erector set. When there is a large building to be built the crane arrives in smaller easier to manage pieces and assembled on site.
