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:Who is responsible for the construction of the pile foundation of the tower crane?
In fact, in the long run, in a word, what the construction site is finally all party a pay, just clearing the count.
Q:Stringing Paper Cranes Together?
Depends how you want to string them... but use thread and a needle. If you want to string them vertically, put the needle through the body of the paper crane... I not sure about horizontally. Too keep them in place, place knots below the body of the crane. I hope this helps, but I hope another more experienced person answers this :P
Q:Can someone explain the support cables on a tower crane?
That depends on the load the crane needs to lift. Those cables will vary from 1/2 inch to about 2 inches. The cable is composed of individual strands, woven together, with a fiber core. The core allows the strands to move, such as flattening out as they move over the pulleys. The core also carries the oil needed for lubrication. The cables are usually rated at 1/7th of their real capacity for safety reasons.
Q:In order to ensure the stability of tower cranes, generally along the height of the tower and building a number of meters attached
Self lifting tower crane tower 45 meters high to prevail, such as height of over 45 meters, each increased to 10 meters (less than 5 meters, excluding) demolition costs increase 20%, off-site transportation costs increased by 10%.
Q:anybody know anything about the Crane Fireball Hi 4E ignition?
Crane Fireball Ignition
Q:What can be done to get rid of protected cranes from tall pine trees in front yard?
Give the U.S. Fish and Wildlife Service a call I'm sure they will help in some way.
Q:1000 paper cranes a myth?
Yes, it is true. My sister-in-law folded 1000 golden cranes (with some help), when she married my brother. They had them mounted in the shape of a crane and framed. It was beautiful.
Q:How to select tower crane type according to the height of building? Seek explanation
This depends on the height of your building, the area, the choice of tower cranes, the model is different, his work coverage is not the same. Now for tower crane, height is not a problem, mainly depends on the size of your building, not in the crane's scope of operation.
Q:Dawkings' Boeing crane. How did it arise, and continue to work?
Bit by bit you may come to realise that complexity out of simplicity is much easier to comprehend than complexity from nowhere. The crane idea is from Daniel Dennet I think, and the boeing being assembled by chance is more or less what happened only bit by bit through evolution and natural selection. God is the complexity from nowhere to which I refer. Self-complete creator? did he make himself?
Q:Why did Dr. Crane work for Ra's Al Ghul and with Falconie?
because they all wanted to f*ck up gotham
