A: Normally, as for the main force bearing steel structure, Q345B is adopted; as for the assistance force bearing steel structure Q235B is adopted. All of the raw material is outsourced from qualified steel factory in China.

Q: What is 3 main mechanism of the  tower crane ?

A: there are trolleying mechanism/ slewing mechanism/ hoisting mechanism.

Q: i saw a PS3 in a claw crane game at Six Flags Over Georgia i wonder how you can win it. It is possible to win it... somehow. I thought that the strategy was to lift the prize that is closest to the hole. I almost won a Kinect that way. So are there any other strategies??? Don't say buy 1 or there isnt a way to win because there is.
The crane machines work in such a way as to only make the claw strong enough to hold prizes after a certain amount of attempts so as to limit the amount of prizes taken.
Q: In the Legend of Sleepy Hollow Ichabod Crane has come from?
In 1799, young constable Ichabod Crane is sent from New York City, New York to the fledgling settlement of Sleepy Hollow to investigate a series of ghoulish murders.
Q: Thanks to anyone who helps ^^
flower-ohana butterfly-chocho blossom-sakura get back with the rest
Q: How do you jump a crane? I know you jack it up but how is that done?
I have no idea what you mean by jump a crane? What type of crane? Truck mounted, overhead, pedestal?
Q: I need it for my English class, not to cheat, but because my literature book only has an excerpt, in which I didn't even know Yukiko's name. And my teacher insists on finding it out for ourselves and I just want to know what the story is about and what the scandal repeatedly implied in the excerpt is.
It's been a while, but I believe the story is about a young girl who gets cancer, and sets about making 1,000 paper cranes for good luck, but she never made to completion. Just google to find info, or see if you can download the book.
Q: What does "slewing up" and "under rotating" in the slewing form of a tower crane mean?
In short, when the tower rotates in the form of a tower, the tower is stationary (ie does not follow the rotation), and the form of the lower turn is the tower will rotate. As for the reasons, the main consideration is the actual needs.
Q: How many meters does the tower crane installation height require expert proof?
The installation, disassembly and jacking of tower cranes must be carried out by experts
Q: Cranes are normally used in construction in most countries.But I saw some photos that show Iranians are hanging criminals in pubic with cranes instead of gallows.Is it more painful to the dying criminals to the last moment?Do you know why?
they probably didn't have the proper arrangements to carry out the punishment so they used cranes instead of gallows. who knows? but weird really. and it wouldn't be more painful... err... the purpose is to snap the neck... ouch :(
Q: What should the sub contractor do before the installation of the bridge crane in the workshop?
Baidu search [tower crane tower demolition, lowering section safety technical disclosure]. If it is installed, remove the "two words" to "installation", and other contents are adjusted slightly.
Q: im really curious about the 1000 paper crane legend. i went on many different websites to learn about it. one said that you are supposed to have 25 strings to hold the paper cranes (40 each) on it and is that true? also a lot websites said that they used them for weddings so do you have to use them for weddings? or can it be any wish you want? i have a few more questions about it but i will ask whoever seems to know the most about it. thank you:)
Most people give paper cranes to their love ones who are ill. Since it is a tedious job, they will all help each other in folding it. Shalbi I may be wrong, but I know that to be able to make a wish, you have to fold the cranes yourself. The wish can be anything, but the most common wish is to recover from sickness and have a prosperous life. A crane signifies longevity and fidelity that is why they like to use them on weddings. ^_^
