As a result, the one-time qualification rate of the products is improved and the company is able to win continuous trust from customers。

1. The lifting boom and balance boom adopt cantilever boom structure, which reduces the hoisting modular and makes it more safe, convenient and flexible to install and uninstall, and reduces the requirements for hoisting equipment and the site.
2. Multiple special mounting brackets are available, which saves the installation time and ensures safe and quality installation.
3. The lifting boom adopts cantilever boom structure and variable cross-section materials, featuring more reasonable structural stress and long service life; and it is easier to make different combination of boom length.
4. It adopts standard sections (for models of over 12t) of piece assembly structure, split structure stock, and assembled platform, which meet the transport requirements for standard container.
5. The extra-long boom is designed with a rope-supporting trolley, and the speed of which is 1/2 of that of the luffing trolley, which can achieve the most optimum rope-supporting effect. The structure has applied for national patent.
6. The lifting mechanism adopts speed regulation by frequency control or by eddy current brake series resistance, featuring good lifting performance; The slewing system adopts frequency control by torque electric motor or by coil winding type electric motor with hydraulic coupler, featuring smooth operation and small slewing impact.
7. All kinds of safety devices are reliable and easy to adjust; both the safety monitoring control system and traditional safety system are available, the double system ensures safety operation of the tower crane; the hydraulic system adopts low/medium pressure design, featuring higher safety and reliability.

Q:I am kinda really sick of paper cranes, and I was wondering if there's any good method of making paper birds that look, well, like birds. I checked out the one website with instructions, but, well, look at it. I tried it.: I haven't made the other birds on this site but they have a pelican and an owl. I think the pelican looks a bit crane-ish but it may look different in reality. Have fun!

Q:I am writing an annotated bib about this topic and I'm not sure where to start looking or what could and couldn't be considered as a theme.: Stephen Crane Works

Q:my sister would like to know this for some strange and bizzar reasion: It depends on how many people are making them. Depending on skill it takes about 2-5 minutes to make a crane. If you dedicate 5 hours a day that makes 7-50 days if one person is making them. Cranes are often made for memorial. It is a Japanese tradition, especially for Hiroshima. You make 1000 cranes as a memorial for the lost lives. She should definitely get her friends to help.

Q:So Pretty much, there is a crane, and there are four blue minions on top. I can pick them up, and carry them back and forth, but I can't get them down. If I drop them in the middle they always die. Can somebody give me a way to beat this?: Found the answer!:) By that point, if you did everything right you should have 8 blue minions. Put 6 of them on the crane and 2 of them(with a guard marker) in the middle where you ar gonna drop the ones from above. Then when you drop them, the ones guarding will pick them up and heal them.:) P.S.A tip, if you want the crane to come back slower don't remove all the minions from it, just remove 2 and the rest will slow it down. Hope this helped, have fun.:)

Q:Has a gift what im a telling that person.: the meaning is if you make a thousand crane your wish will come true. and if you give someone a paper crane it symbolizes friendship! :)

Q:How does a crane get down from a skyscraper once they're done using it? Like the crane on top of the skyscraper, do they get take it apart?: Can only be assumed that the jibs are first dismantled then the actual crane base lowered down by a second crane or even helicopter

Q:what is the common cause of crane accidents: Overloading,crane outriggers not properly deployed or on soft ground, gust of wind causing load to sway out of control, operating too close to power lines, worn cables, mechanical failure.

Q:I have got a ton of Mosquito Hawks in my house. Should I just let them be or will the problem get worse? Plus I read they dont bite humans but will the bite rabbits? I have 2 house rabbits that I am concerned about.: Mosquito Hawk

Q:how is a tall crane constructed? how can they put the crane on top of its tall body frame?: They first construct the top of crane on the ground with help from other mobile cranes. This includes the long horizontal part with the operator's cab, and the concrete counterweight. this is then placed on a climber, with which the crane kind of builds and climbs itself to the necessary height. Every vertical section of the crane is placed in the climber. When the piece is in place, the climber climbs to the top of piece from where the next vertical piece is placed and so on. You can see how a crane is constructed in the website I've cited below:

Q:I wanna get my gf this nice necklace but I suck at the crane games. Is there a way to cheat?: a partial cheat that i use is 1st looking to see which items are at least open enough to get 2nd when i start up i get to the item then to go the left and right of item and adjust which way i go then try to aim for the middle of the item wanted then there is an 80 % chance that i will get the item i am aiming for but some of those crane games are rigged to the point you have to go at least 2 or 3 times depending on what type items are on there because the crane arm looses strength especially if it is far away from the exit hole
