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 does a paper crane represent/symbolize?
A fun activity to do when you have nothing else to do!
Q:On a geared bulk carrier, where are the onboard cranes controlled from?
? ? ? Onboard Cranes from the cabs on each Crane , where'd you think from ?
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:what is the function of load indicator on a crane?
it indicates the load being placed on the crane so the operator can keep the load within limits.
Q:Girls name for the last name Crane?
I think Emma Crane is very cute. One not so common way of using emma is Emmaline. Emmaline Crane is very nice. Although, I think I like Emma a little better. I know many people make double names with emma. Such as: Emma-Kate, Emma-Grace, Emma-Katherine, Emmaleigh. Oh, and I do like Lily Crane!! I prefer the spelling Lillie instead of the flower spelling though. Some suggestions: Emmaleigh Crane Amberly Crane Hadley Crane Ashlyn Crane Kylie Crane Ella Crane Arabella Crane Sophia Crane Sophie Lilah Crane (pro. lie-luh) Natalie Crane Jensyn Crane LeighAnna Crane Emilia Crane Emme good luck. I hope this helps you in finding a name. :)) -Emilia S♥phia
Q:How does cranes make use of simple machines?
Well, think about it. The cables of the crane pass over pulley. That's one simple machine right there. In addition, one that not everybody would think is a lever. On the back of the crane, there is a huge weight. The purpose of this is to compensate for what is being picked up at the front of the crane. Having a very heavy weight on the back of the crane allows a load to be picked up far forward at the front of the crane. Otherwise, it would topple over and people would die. And that would be bad.
Q:What are the types of common tower cranes?
Tower crane, tower crane. Tower crane according to its different types, there are the following classification methods.(1) according to the structural typeThe fixed tower crane by connecting a fixed tower in the foundation or structure, tower crane lifting operation.Mobile tower crane: a tower crane with running device and can walk. According to the running device, it can be divided into rail type, tyre type and caterpillar type.
Q:Cranes or storks?
Depends on where you live ? Stick to Ornamental Pheasants or Ducks,Storks and Cranes,need to be penned in at night because you will have to pinion them to prevent them flying. Try some Golden Pheasants for a try ,Lady Amherst are becoming a rare commodity and are quite expensive,if you have Foxes and Mink,then no matter what you get you will have problems these two predators.
Q:do you have any info about whooping cranes?
The Whooping Crane (Grus americana) is a very large crane. It is the tallest North American bird and the only crane species found solely in North America. Adults are white; they have a red crown and a long, dark, pointed bill. They have long dark legs which trail behind in flight and a long neck that is kept straight in flight. Black wing tips can be seen in flight. Immature birds are pale brown. Their breeding habitat is muskeg; the only known nesting location is Wood Buffalo National Park in Canada and the surrounding area. They nest on the ground, usually on a raised area in a marsh. The female lays 1 to 3 eggs. Both parents feed the young. Usually no more than one young bird survives in a season. Loads more on Wikipedia (link below) - good luck
Q:How do you make a thousand paper crane lei?
But I do different from step 11 on Step 11: Normally they fold along the red line. I dont. On step 10 you see the cross line in the center +. I then fold the right pointy toward the center. Do the same for all. Step 12: I the filp the right top layer to the left, same with the back side. Step 13: fold the bottom point to the top(one layer only) filp to back side, do the same. Step 14: flip right layer to the left again, same with the back side. Step 15: Pull and done.
