The tower crane is a hydraulic tower crane with swing top, horizontal jib and mobile trolley. It has the hoisting moment for315Kn.m;the maximum hoisting load of 3t and the maximum working radius of 39m.The hoisting height of anchoring tower crane is 25m and that of climbing tower crane is 100m.
The tower crane has ingenious design, beautiful shape and simple structure .It is easy to operate and maintain, and is safe and at a reasonable price .It is an ideal construction machines for construction enterprises. It has hoisting mechanism, swing mechanism, top-rising mechanism and radius mechanism, which can work individually or cooperatively to make a high efficiency. The top-rising mechanism is used to raise or lower tower. The hoisting mechanism has 3-speed electronic motor respectively for high, medium and slow hoisting speeds. It has flexible swing mechanism and radius mechanism and slewing mechanism for vertical and /or horizontal transportation of building materials in one time.
The tower crane has complete and sensitive protection devices such as hoisting weight limiter, hoisting moment limiter, hoisting height limiter, radius limiter and swing limiter to ensure of regular operation. It also has rest platform, guardrail and other protection devices. Driver’s cab is at a side of rib and has big space and wide visual field.
The tower crane has excellent performance and is suitable for hoisting in short civil or industrial buildings or loading or unloading in ports or goods yards

- Q: Do you believe in the 1000 folded paper cranes give you a wish?What is the entire process in it all?And can they be in another persons hand like if I make 1000 an a few are at my friends possession will it work?
- I do believe in it, somewhat. Years ago one of my teachers who had cancer made 1000 paper cranes and then beat it shortly after. I'm not sure about the process, or how it works exactly, but I do think that I believe in it. she still has those paper cranes hanging up in her classroom.
- 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: I'm a bit confused as to what happened to him. I guess I skimed a bit at a certain important part of the book. When Seneca Crane's name was written on the dummy during training, why did the people gasp at the name written in berry juice? What happened to him? PS. I am at the begining of Mockingjay. So no spoilers please. (:
- In the end of the first book, he was put in a room with a bowl in the middle. In the bowl, there were berries. Very deadly berries. This is significant because in the arena, Peeta and Katniss threatened the Capitol that they would eat them and kill themselves. If that happened, there would be no victor. President Snow wanted Seneca Crane to kill them. But Seneca Crane let there be two victors, instead of one or none. So, back to the point. Seneca Crane was punished because he couldn't listen to the president's orders. So, he was put in a room with no food, water, etc. If he got hungry he, he had to eat the berries. So, he died. I don't know how you missed that, but I hope this helps! :) I LUV U PEETA!
- Q: some people call it a crane, others say claw but the point is...where can i get one? i dont want a huge one, and i dont want a small one. A medium size one. the shops have to get them from somewhere right? oh, and i'd rather not get one from Ebay. is there a business or something? thank you!
- You can buy that stuff at gamig stores that sells alot of gaming equipment
- Q: IN HEAVY LIFTING WORKS, Which type of crane is better ? Certain area I See Cranes with JIbs are being used and for same type of lifting jobs i See TELESCOPIC CRANES are used. Ofcourse both are Mobile cranes. I see JIB cranes are assembled at site ...
- Both okorder /
- Q: It`s like a big box filled with toys and u insert a coin and then u have 2 handle the small crane to pick up a toy...
- Skill Crane. We used to have one in our arcade.
- Q: Well,i just LOVE this piece of origami work...I've tried so many (kinda the same) instructions but i always get confused on the step 3-4...do you know any easy instruction,with clear explanations for a begginer?thank you already~~
- visit okorder / that's the place where I learned folding paper cranes. XD I've always loved them.
- Q: How To Make Origami Crane?
- You okorder and see how to make origami crane step by step
- Q: How do you jump a crane? I know you jack it up but how is that done?
- I have no idea what you mean by jump a crane? What type of crane? Truck mounted, overhead, pedestal?
- 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.
