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.

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: (a)What is the power output of the crane. (ignoring losses)?(b)If it takes the cran2 2 minutes to raise the payload to its final height, how far above the ground is this?(c)If the cable were to break as the payload reaches its final height, how fast would it be traveling as it hit the ground?
- a) As the crane is lifting at constant speed, there is no acceleration on the payload, therefore the net forces on the payload are equal to 0. Therefore the crane overcomes just the force of gravity = 500*9.81 = 4905 N Power = force * velocity = 4905 * 0.7 = 3433.5 W b) distance = speed * time = 0.7 * (2 * 60) = 84 m c) assuming that the cable breaks while it is still going up at 0.7 m/s, therefore initial velocity upwards = 0.7 m/s. using v? = u? + 2as: v? = 0.7? + 2(-9.8)(-84) = 1646.89 v = √(1646.89) = 40.9 m/s the payload will be travelling at 40.9 m/s when it hit the ground.
- Q: which crane makes only one Life Partner ?
- Apparently, although traditionally, most cranes were thought to mate for life, recent research suggests that they do actually change partners during their lives. I don't know how extensive or how conclusive the research is, or what species it involved, but it does suggest that the folktale may not be true.
- Q: I'm confused about one of the final scenes, where Seneca Crane is locked in the room with the nightlock berries. Does this mean that he is supposed to eat the berries and presumably die? Or is it symbolism of some sort of distaste in the way he ended the Games?
- Yeah, basically President Snow has him killed. The berries represent this. The whole point is he goes into the room, sees the berries and knows he is being killed for allowing Katniss and Peeta to use those berries to cheat the system.
- Q: He has to be in his 30's to 40's but I can't find anything that gives me a definite age.
- Okay Well, You havent specified in what, but presuming you mean in the comics, and baring in mind he was the psychologist when Thomas Elliot and Bruce were only 7-8, then the bare minimum he could have been then was 21, though he was likely older. THEN presuming Bruce is around 35, though he also is probably older, then the bare minimum Crane could be is 48. that being said, he is likely between 48-60. He just looks good for his age ;). this of course is in the comics, however. The movie is different.
- Q: Are tower cranes the same as tower cranes?
- Tomato, you tomato, potatoes, you potatoTalent exchange of tower crane and tower crane
- Q: what are The performance parameters of tower cranes?
- The technical performance of tower crane is expressed in a variety of parameters, the main parameters include the range, starting weight, lifting torque, free height, maximum heightand so on; its general parameters are: a variety of speed, structure, weight, size, tail size and gauge wheelbase, etc.
- Q: I herd that there was some sort of legend that if you make a certain # of paper cranes you get a wish! Do you believe this to be true? Do you have to make 100 cranes or 1000 cranes?
- For the best answers, search on this site Right now, that my contacts answer my questions for a change!
- Q: How were Churches and really tall buildings constructed hundreds of years ago before the invention of cranes?
- Scaffolding, pulley systems, pure strength.
- Q: How do I get on the cranes on the Highrise map in MW2?
- NO okorder /
- Q: How do Crane Motors Work?
- I'm not 100% familiar with this but this should be pretty close to the answer. Simple/standard crane motors work by applying power first through a rotating steel shaft into a gearbox. The gearbox allows the gearing ratio to be changed (to trade rotation speed for torque or torque for rotation speed). Another steel shaft carries the power out of the gearbox, again through rotation, to a spindle (think big thimble) around which steel cable is wrapped.
