Main Features of Tower Crane
Our tower crane is self-erecting and wall-attached tower crane, in addition to it's advanced parameters, reliable performance, well-looking appearance, and excellent quality.
It has characteristica such as long boom, largeworking coverage, hydraulic rising, and tandem mounted tower body.
It's design idea shows advantages including simple structure and good applicability, convenient maintainability, and lower price at the same time to emphasize meeting the requirement from construction units at different levels.
It's lifting height is obviously increased thanks to its self-erecting and wall attached function.

FAQ about Tower Crane
Q: What kind of steel used for tower crane ?
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 about our tower crane warranty?
A: Usually there is one-year quality warranty including main electronic parts (not including consumable parts). There are consumable spare parts together with whole machine and normally they are enough for one year.
Q: What is 3 main mechanism of the tower crane ?
A: there are trolleying mechanism/ slewing mechanism/ hoisting mechanism.
- Q: How to choose tower crane in engineering, such as arm length and lifting weight?
- How to choose tower crane in engineering:1, according to the general layout plan on the mechanical layout requirements to determine. The tower crane's arm length should be swept to the required area, otherwise the worker's formwork and materials can not be transported vertically. (tower crane is the main tool to solve vertical transportation, and auxiliary tools are derricks and double cage elevators)2. After a project has been obtained, it is important to design the layout plan of the field machinery at first. It determines the position of the tower crane and uses several tower cranes, etc. it also conforms to the requirements of economic rationality.3, we should take into account the location of the tower crane, but also take into account the length of the tower crane, but also to meet the requirements of the site construction schedule.
- Q: Preferable short poems or phrases in Chinese.
- this one is about cranes We thought they were gulls at first, while they were distant- The two cranes flying out of a natural morning, They circled twice about our house and sank, Their long legs drooping, down over the wood. We saw their wings flash white, Frayed at the black tip, And heard their harsh cry, like a rusty screw.
- Q: ...the crate weighs 4000N when resting on the ground. Find the followinga)The tension in the cable necessary to do thisb)The work done by the cablec)The work done by gravityd)The total work done by the systeme)The final velocity of the crate
- Ghee is clarified butter! The rest sounds like homework!
- Q: I caught this crane fly in my garage but is almost the size of a dragonfly. It has a 3 inch wingspan. I saved it in a jar because I though no one would believe me. so do they really get this big or is this thing a freak?
- Yes. Here in Southern Oregon (and in CA too) we have giant Califronia crane flies. They really do get that big, its not just a freak.
- Q: Plus why the symbiot instead of bringing the dark side of the carrier brought the gay and jerk side?
- 1) Something happened to the crane - it doesn't matter what - it was an excuse to bring out spiderman, What happened isn't important. It was a kind of malfunction anyway - NOTHING to do with any villians 2) Gay and jerk side? He wan't being gay, but because he was a jerk in the first place that is why he didn't really know how to dress up properly and being up himself means he doesn't recognise it - which by the way, was well scripted into the movie. It was a bit of a comic relief. The symbiot brought out the darker side of him but that doesn't mean it KNOWs to make him behave appropriately.
- Q: My best friend is going to live in Japan for about a year soon, and I want to send him a birthday present while he's there. A lot of the places I've looked say it's common to make 1000 cranes for people as a wedding present, or in preparation for your own wedding so I'm not sure this is an appropriate gift -___- Also, I have no idea how I would ship them to him...
- A 1000 cranes set is a lovely thought would be a wonderful present. But you have one problem. How many boxes will it take to ship 1000 origami cranes to Japan? How much will it cost? Remember, airmail is very expensive, USPS doesn't do overseas surface mail anymore. Mailing parcels to Japan with DHL/UPS would cost you at least $80 for 20 pounds or less. You would do better to send your friend cash by wire transfer. Furthermore, since your friend will be in Japan for 12 months, I would guess his living quarters are not spacious. The average home is only 1000 sq feet in size. Apartments can be as tiny as 100 sq.ft. Where will he put 1000 cranes? He will have it for a few months before he has to pack to return home. What will he do then? Toss the cranes or ship them home? I believe he would prefer to have the wire transfer. Cost of living in Japan is high. Cash is going to be so appreciated even if 1000 cranes gift is a sweet sentimentality. Check the sites referenced for cost of shipping.
- Q: The role of slewing limiter in tower cranes is limited
- The function of the rotary limiter is to restrict the large arm to stop at a certain setting. Protect from turning to dangerous range so as to avoid collision and other dangerous accidents!The function of the amplitude limiter is to restrict the car to come out or return somewhere to stop and protect the car from or within certain dangerous range.The hook safety device is to prevent the wire rope from falling out of the big hook, so as to avoid falling and other dangerous events!
- Q: ok, so if chad is a crane then why doesnt he stay in the mansion? he is a crane right?
- Yes he is a Crane! It turned out that he is Alistair's son by Liz and not related to Whitney in any way because Liz and Eve are only step-sisters. LOL I do believe they stay in the Crane mansion now. It hasnt been made real clear but they are there quite often, even at bedtime / night time, and she is always there to talk to Teresa whenever the blackmailer scares her. Also, his birthday party last week was at the Crane mansion wasnt it? I think they stay there now that Alistair is no longer there.
- Q: I'm just curious about it, and i need it for a fan fiction story i'm writing. thanks ^__^
- Yes. It is genetically coded into japanese children before birth. As soon as they are born they know how to fold paper cranes. But it takes a couple of years for them to develop the hand coordination to actually do it.
- Q: How did Romans make columns in roman times Without cranes?
- They simply lay the stone down, chiseled out the column, then stood it up via an A frame, however the Romans did have cranes, (not the massive things of today) but mobile wooden ones with counter weights at the back that operated on a system of pulleys (they even had cranes that operated on water)
