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:I was wondering if Steam Cranes are still used to clear train derailments or are the all mothballed now? What do they use to clear derailments now days if the not the Steam Cranes? Also way are there 2 types of hooks on the crane anyway? Thanks
I am not aware of any steam cranes, they are all diesel as far as I know. the two types of hooks are for different types of pulling, one is generally for straigh lifting and the other for pulling across the ground or up an embankment where the pulling force is at somewhat of an angle to the equipment. .

Q:My grandma has just gotten cancer and I want to send her a paper crane in her get well card. However, is it bad luck to send just one, do you have to send 1,000? I would like to send 1,000 but i don't have the time, experience with origami, or enough room in the envelope, and i only have till tomorrow.
You can send her a few NICE paper cranes and write her a nice letter, it's the thought that counts.
Q:So I have this teacher for almost 4 years and I didn't very much liked her style of teaching. During my sophomore year I was getting fed up with having her in my favorite class. Unfortunately she got ovarian cancer. Now that I think for what she has done and not acknowledging her, I feel really bad. To make things up I wanted to give her I guess the 1000 cranes before I leave for college.Is it okay to give it to her? If so, what do you do once you have all 1000 of them folded?
Well I don't think u have anything to feel bad about. Does everyone need to be treated like some kid of a hero because they have cancer? I think that is stupid. With all the people in the world everyone is gonna dislike someone. A ***** is a ***** no matter what disease she may have. After you fold 1000 cranes I think you are supposed to make a wish. Now if you wished that there was something that would remove her from your class, then I would feel guilty.But other than that I don't think you have anything to feel bad about. Or if you were really hard on her too but don't think that jut because she has cancer that she can be a ***** and everyone has to worship her. That is just bullshit. If she gives **** than she must be prepared to take ****. And as for giving them to her, I think it would be a nice gesture, but just think about it. What would you do if someone gave u a thousand paper birds? I think very few people would keep them. Now I don't know if you are supposed to give them away, but if you are, I think you should ive them to someone who means something to you personally and not because they have a disease. It is human nature to not like someone and just because they have cancer it shouldn't change that unless this experience has made them a better person and all that **** that you always hear about. But I don't think you have anything to feel bad about and not liking a teacher is completely normal. Please e-mail me your thoughts on this.
