Main Features of Tower Crane
1) This kind of crane adopts standard section hydraulic lifting and connecting.The max. height can reach 180m with wall tie ins.
2) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.
3)The range-change structure drives the trolley moving on the horizontal crang jib, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.
4) The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation. The crane is equipped with lifting height limiter, trolley ranging limiter, moment limiter, weight limiter etc..
5)The cranehas scientific layout and handsome appearance. The drivers cab is set independently on one side, with good vision field. It creates a good working environment for the operator.

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 should I go about stringing paper Cranes together??I alreadly know how to make them, its just that I have no clue how to put them together
- You poke a hole in them and string them....
- Q: Do you find it ironic a crane crashed into Mecca's holiest mosque on 9/11?

- Q: I am making a lot of little paper cranes, and so far I have 144 cranes. I want to know what different number of cranes mean. Like, what do 100 cranes mean? Good luck? Long life? I don't know!!! So what do 100 cranes and 1000 cranes mean?!? Please answer if you know, this question is almost driving me crazy!!!!
- A Japanese legend indicates that anyone who folds 1000 paper cranes will be granted a wish. Sadako Sasaki was a Japanese girl who died from radiation sickness from the A-bomb dropped on Hiroshima.

- Q: death... by exile!Also, which Batman movie was your favorite and why?Mine was the first because it was cool to see how Wayne started and got all the Batman stuff and the movie was less confusing, haha. Plus I thought the actor Cillian played Scarecrow really great :)
- Yes, that was such a nice surprise. He was a great villain in Batman Begins. For a split second, I was like Wait a minute - the last time I saw Dr. Crane, he was freaking out on that Toxin they released into The Narrows. . ., but then, I remembered - he and everyone else affected by that poison were given the antidote after it was produced by Wayne Enterprises. His role as the judge at the sort of Reign Of Terror style court system is perfect - Crane clearly enjoyed watching people suffer mentally, liked seeing them terrified. Sadistic little twerp. Tough call on favorite.. . while I think the first two thirds of The Dark Knight are probably the very best of the series. . . my personal fave is Batman Begins, too. I can remember the first time I saw it, and as they're showing the establishment shot of those mountains in Asia, Raz Al-Ghul's lair. . . I kept thinking, this is different than any other Batman stuff I've seen - this is cool! Kinda sad it's over! :( Edit - And I just wanted to add - I've used that line Bruce's dad says with my own little son: Why do we fall? :)
- Q: I know this is a longshot someone will know what I'm talking about... but I just got a flash memory of a poem where a bird with long legs (I believe cranes, but it could have been flamingos or some other bird) and kids threw stones at them and their legs just snapped.... that's all I can remember, but I remember whatever the line was describing the legs snapping really well because it was in such sharp contrast to the rest of the poem.... anyone have any clue what poem this is?
- The Crane and The Crow'-Aesop's fables The farmer threw the stone at the crane and broke both his legs. The injured crane said to the crow, What has become of your God-given prophecies? Why didn't you warn me that his was going to happen?
- Q: I'm making 1000 origami paper cranes. I started 2 days ago and have 135 done so far but I was wondering what do to with it after. I don't want to just make them and have them sit in my room forever.
- Well if you don't want to keep them you can look up organizations that wish to use them for a project. There are a lot for Japan, one that was organized recently for the tsunami was accepting cranes for a fundraiser (every crane sent in earned a certain amount of money with the finished collection being placed in an art museum). I know some hospitals accept cranes for the children's ward, that is what my class did in elementary school we made 1000 and the hospital used them as decorations for the Christmas tree. Then there are individual projects that people start online with which they are accepting cranes to fulfill the one thousand mark for people they know who are sick etc. (relates to the story behind the 1000 paper cranes practice). As a side note if you contact the organization you find a lot of the time the shipping is prepaid you just have to drop them off at the post office. Hope this helps.
- Q: Does anyone have any info on John B. Crane?
- Do you mean the Lecturer John B. Crane of the Redpath Chautauqua Collection? Thats the only one I know.
- Q: total motor kw-100kw,crane class-m6,the crane should be operated on ups as the conventional electric supply is off , back up time require-30 min.
- To account for the inefficiencies, and startup currents, you should have a 200 kW (200 kVA) inverter with peak power of 800 kW. The batteries would have to store and deliver about 150 kW. But lead acid batteries would need to be of a higher capacity to guarantee that power level for 1/2 hour, which calculates to 75 kW-hour. I'd say 100 kW-hour capacity. A large 12 volt battery can store about 100 amp-hours which translates to 1 kW-hour, so you would need 100 of this size batteries connected in series/parallel. I made a lot of guesses, you should get better numbers for the motors, the inverters and batteries for a more accurate calculation. An inverter of the size needed will not be a 12 volt unit, but probably 48 or 96 volts DC. so you need to configure your batteries in series parallel to get that voltage. Altogether, the 100 large batteries make this not a practical solution. There are lots of large cranes in the world, what do they use for backup? And why do you need backup. With no power, the clutches would keep the crane and loads fixed in position, my guess.
