QTZ40(5008) tower crane is hoisting and conveying machinery which is designed by Shandong Fuyou Co., Ltd. by fully utilizing the group technology, the combinational design technology and the finite element analysis technology and taking the tower crane microcomputer design platform as a tool and has excellent performance.

The crane is a horizontal-arm-rest trolley-amplitude upper-revolution hydraulic lifting type crane which has the effective amplitude of 50m and the maximum lifting moment of 438kN•m. The tower crane has the lifting height of 29m and the adhesion lifting height of 120m (2 magnification) during independent use.

All the speed indexes of the crane meet or surpass national standards.
The crane has the total installed capacity of 24.9kW, features advanced parameters, excellent and reliable properties, attractive appearance, high quality, simple and practical structures, advanced safety devices, convenient maintenance, safe usage and reasonable prices, and is ideal construction machinery for many medium-small construction enterprises

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.

Q: how do they get counter-weights onto high cranes?: The top section of a tower crane, including the cab, boom, and counterbalance, is erected on the crane's base, using a portable crane. After that, there is a mechanism on the tower crane that jacks up the top and allows another tower section to be inserted under it to increase the crane's height.

Q: How do you erect a crane. surely you would need a crane to make a crane.?: Modern building cranes (the tower cranes that you see on most building sites) have the ability built in to jack themselves up as the building grows. Jacks raise the crane at ground level, allowing a new section to be inserted at the bottom of the tower. But the crane arrives at the building site in pieces, and a small truck-mounted or crawling crane may in fact be required to assemble and erect the tower crane - so, except for the smallest cranes that could be put up by hand, you are correct.

Q: anyone can tell me the common steel tube material using for crane boom, both main chord and lattice boom. thanks !: Steel, like you said, do you want an exact specification? That will vary by whether it is a very long and slender tall crane or a shorter heavy duty for considerable loads. It may even vary depending on whether the manufacturer has as a goal an extra light weight unit using more expensive stronger steel or is willing to use thicker walls to use more ordinary steel. That is what engineers are for.

Q: Do cranes play major role in Japanese culture? How so? Do cranes live in Japan?: Red-crowned cranes (also known as Japanese cranes and Manchurian cranes) breed in Siberia and Mongolia during the spring and summer but migrate in flocks to Japan, Korea, Taiwan, China, and other East Asian countries for the winter season. They are the second rarest crane in the world, and it is known as a symbol of good fortune, longevity, and fidelity in these countries. In Japan, they are considered to be a national treasure. They frequently appear in art, literature, and folklore. I remember a tale about a lonely man in winter and finding a crane nearly dead in the snow. He nursed the crane in his home until it was well enough to fly away on its own. The next winter, the crane came back as a beautiful maiden wearing the finest red and gold silks. She promised to live with his man and weave silks for him to sell. The only catch was that he was to never look at her while she was working. They lived happily for a while, until one day he couldn't hold in his curiousity any longer. He took a peek behind the screen and saw a crane weaving silk with its feathers! Naturally, the crane noticed and flew away, never to return. In Japan, cranes are said to have the legendary lifespan of 1,000 years (hence, the folding of 1,000 paper cranes). Cranes are also known to mate for life, making them a popular motif at weddings and anniversaries.

Q: From what I'm understanding in the first stanza, a women lost her lover to the war because he fell off his horse...Is that right?: Yes, Stephen Crane talks about lost love and sacrifices in his poem. The basic casualty of war. A lover, a father and son are lost in his story and those that are left behind he tries to console. The poem is noted for the ironic use of war is kind. We all know that War is really not kind. The poem’s speaker, simultaneously sympathetic with the victims of war and cynical about the purposes of war, implicitly criticizes the image of the romantic hero, showing in graphic scenes the realities of battlefield death and the emotional torment it causes for those left behind.

Q: I don't really believe that the wish will be granted.Anyways I've really been into Origami and I remember reading in my Heroes book (slash the show) that a certain number of cranes means a wish. But before I start making all these cranes, I want to know if it's 100 or 1,000.So if you haven't gotten it in your head yet the question is:Is it 100 or 1,000 cranes to get a wish: 1000 Cranes Wish

Q: I'm not scared of spiders anymore. If I see one than I can kill it easily, but when I see a daddy long legs crane fly, I freak out! Those things are hugeeee. I could never kill one without being freaked out to death. I heard that they don't even bite, but I'm still scared. There's one in my living room and I ran out. So I planned on staying in my room the whole day and just hope it doesn't show up in the bathroom tomorrow morning when I shower! I'm 14 btw?: This is a selective entomophobia. Basically, you don't fear many insects or spiders, but specific ones trigger your anxiety. Your problem is not the bugs or spiders,(they are harmless) but your fear. This is something 'you' nurture by dwelling on this fear when you see one of these particular critters. I'm glad to hear you no longer fear spiders. you will see the same when you overcome your selective fear. You may even come to realize that the spiders and insects you do fear,are totally harmless, and you may reach a point where you can just ignore these. True, the crane fly is totally harmless and do not bite, sting, or inflict any form of hazard to humans. They can be a nuisance buzzing around your face,as they can be persistent. Adolescent years seem to be when phobias are the most prevalent, but also the easiest time to overcome fears. If you can learn to control your fear, rather than let it control you, you will overcome this. you also need to refrain from dwelling on your fear,as this will only make it worse. Last year, one of my favorite pass times was sitting on the porch watching the sunset. a little orb weaver would come from behind the light and spin her fancy web. Often, I would catch a crane fly that was bothering me and toss it into her web.

Q: Why are crane flies called mosquito eaters?: Adults crane flies seen in spring and summer. Found in damp woodland and beside woodland streams ; leathery larva lives in watery margins, so might eat mosquito's

Q: I read this book recently and i got emotional over it. It relates so much to my life and i think maybe i know what my dad was thinking before he died. I was just wondering what was your reaction after reading this short story?: Sniff Sniff. 'tears rolling down my cheaks.

Q: So, this might seem like an odd question, but here goes.I work in an office and outside the windows there's a crane. Every day I come in from work, it has turn a little. The half-finished building that it stands next to is not being worked on and there's never anyone using the crane during the day. There's no other construction going on in the area is stands at.It's pretty high up like 6th to 7th floot and it's in a windy town. Does that matter?Why would someone turn around a crane during the night? Is it all a scheme to make me paronoid because they know I'm starring out the window most of the day?: I guess it would be pretty windy up there at the top - maybe it is not fully locked, and the wind blows it around a little bit.
