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: Tower cranes sometimes have very long booms, but seem to usually have fixed counter-weights at fixed positions behind the cab. Why doesn't it flip backwards when there is no load, or flip forwards when a load is way at the far outward end of the boom? It seems to be a very large range of moment arms given that the counter-weight has a fixed one.
I think the counter weights are connected to a pully system that directly interacts with the boom and hook movement. This way it can put more or less pull on the weights according to the amount of weight or position of the weight on the crane.
Q: What qualifications do you need to be a Crane Operator in QLD, Australia?
You need to do a specific amount of hours in training to be a crane operator in Australia, I know that in Sydney, you are certified by the WorkCover Authority, or that's how it was many yeas back. Special emphasis is on loads, and point of load. We do not need a mobile crane tipping over do we. Safety, working near electrical, and on soft ground. Weight you can extend to on a jib. etc.
Q: How do they get the cranes and counterweights down off the top of buildings when finished?
Dereks, which are built along side of the buildings, actually take themselves apart. There is a jacking system which attaches to the segment that is 2nd from the top. This lifts the bussiness end of the crane off the top segment which can then be unfastened and lowered to the ground. The jacking system then replaces the crane on the new top, travels down one more segement and the process is repeated. It is actually cool to watch.
Q: ok I found an injured crane what do I feed it?
Cranes are omnivores. But I would feed crane with vegetarian stuff like grain, berries, plants, roots, seeds, stems, bulbs, fruits, nuts. But if you want make it non vegetarian then rodents, fish, amphibians, snakes, rodents, lizards, small fish, frogs, shellfish, mollusks and crustaceans.
Q: Where are levers used in and throughout the crane
Crane Boom is a lever; pulleys and cables attached to the boom and machinery house create the mechanical advantage needed to lift heavy loads.
Q: More than meters of tower cranes must be equipped with red barrier lights at the top
however, tower cranes over 30 meters above the tower shall be equipped with red light on the top of the tower and jib.
Q: It frustrates me every time I play one of those games i never win. Is there a secret? If so then what is it?
It depends which type of animal crane you are talking about. If it's the jumbo cranes that pick up the huge stuffed animals, they are actually set to give out a win every so many plays, however the number of the winning play varies based on the location. If you are talking about the average sized cranes, the key is to look for a stuffed animal that is light up on top and bottom heavy. This will allow you to grab ahold of the head or neck and pick the animal up. I've found the easiest cranes to win on are the ones that you pick up beanie baby sized stuffed toys. They seem to win, every time you aim the crane to pick up the head or neck. It's a great way to rack up a lot of stuffed animals. While they may not be huge prizes they are reasonable ones, and some of them are pretty cute.
Q: I need to do a report about Stephen Crane, answering the question how did his life affect his how he wrote his books, does anyone know?
Crane is noted for his early employment of naturalism, a literary style in which characters face realistically portrayed and often bleak circumstances, but Crane emphasized impressionistic imagery and biblical symbolism rather than graphic realism. Crane's realism, writes William Peden, is often more impressionistic than photographic; his interest in psychological probing, his innovations in technique and style, and his use of imagery, paradox and symbolism give much of his best work a romantic rather than a naturalistic quality. Both realism and symbolism, the two major directions of modern fiction, have their American beginnings in Crane's work.
Q: when a skyscraper is done being built, how does the crane come down?
Most probably you are referring to the Tower Crane. Interesting questions should have followed, like: How is it constructed while the construction is in progress? How is the placement of the Tower Crane determined? What happens to the space occupied by the Tower Craneafter work completion? How far should the 'boom' (the arm that has a moving pulley) go? Anyway, your question is a good one, because when I had my first construction work, the Tower Crane was already there and I was thinking of how to dismantle it afterwards. The dismantling process, is done part by part, set by set starting from the top going down. Another interesting question is: How would that excavating truck or bulldozer be able to get out of that deep matt excavation after all excavation works have been accomplished? It is interesting to note that an earth ramp is created while excavation progress, until the machine is down deep in the excavation and seems that it is impossible for it to get out after excavation work is done?
Q: Two cranes are lifting identical steel beams at the time.One crane is putting out twice as much power as the other assuming friction is neglible, what can you conclude is happening to explain this difference?
One of the cranes has less mechanical advantage then the other. It's a pulley problem.
