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:Synopsis for the poem Lost Dances Of Cranes?
If this is the poem, you will find several comments at the link provided. Your fields are empty now. Only your ghosts dance while cranes of another kind dance cities into being. All that remain of you are a fading crackle of your energy and some grainy video footage that people in the new cities will watch to marvel at the wonders the world once held. craftygreenpoet.blogspot .uk/20...
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:What can paper crane symbolize?
I don't know what just one means. But making 1000 paper cranes is a symbol of helping someone live if they are near death.
Q:Last week, I decided to make 1000 paper cranes as a new project. I am very craft- oriented, and have made numerous knitted scarfs, crocheted blankets (still in the works), and cross stitch patterns for family members. I have made 2 large cross stitch patterns, one for my grandma (took me 2 years to do) and one for my dad (2 months). My mom's birthday is coming up, and I was wondering if I should give her 1000 paper cranes as a present? I haven't yet given her anything that I made, and I feel bad about it. I don't have enough time to cross stitch a pattern or anything, and I can easily make 1000 by December. Would it be a sentimental present? Should I do it? Would she like it? If not, what should I get her? I want it to be something that I made so that it will be personal.
Sell them or give them to someone who is going to get married. My nephew gave paper cranes to every guest who came to their wedding. Each guest was to write a line of advice or blessing on their crane. Then the cranes were hung on strings with little clips at the reception. It was beautiful! Folding a crane takes time, patience and understanding. These same qualities are vital for a marriage to last. This is why the symbolism of 1,000 hand-folded cranes decorating a wedding is so powerful.

Q:Trying to find an estimated weight for a mobiles crane with a 5 tonne capacity ?
If the crane HAS a 5-ton capacity, then to be able to estimate the weight you would need to know the length of its lifting arm at maximum extension w.r.t the C.G. of the body of the crane. So suppose we have an arm length of (say) 6 mtrs, then the max turning moment at the fulcrum (from front wheels of crane ? ) due to the Load alone = 5 x 6 = 30 You need to add the moment for the arm itself. Lets say the arm is around 1/2 ton. And its c.g. is approx 1/3 the distance from the fulcrum. Then this adds another = 1/2 * 1/3 *6 = 1 So total moment is 30 + 1 = 31 The body of the crane must be MORE than this. Suppose the C.G. of the crane is 2 meters behind the same fulcrum. Then weight of the body must be 31/ 2 = 15.5 tons. Lets say the weight is 16 tons. Then the TOTAL mobile cranes weight would be 16 (body) + 1/2 (arm) ~ 16.5 tons It all depends on the dimensions of the crane, and where the c.g. is located. If the crane has ballast added right at the back, then it's overall weight can be made less since it's c.g. would get shifted further away from the fulcrum
Q:My relatives and their kids are coming the 28th for our Christmas does any body know where I can get a Brio Crane for a 3 year old? most web sites I checked say sold out. Just wondering.
Hi okorder . Please visit it and it will satisfy your needs. Best regards, Soma
Q:What is the standard weight of a tower crane for 1.6*1.6*3 and 1.6*1.6*5m? Kg?
The standard weight of tower cranes for 1.6*1.6*3 and 1.6*1.6*5m is 500KG
Q:how does a crane operator's knowledge of where the centroid is generally located for most uniform objects help them perform their job more safely?
If an object is uniform, it's a fair bet the centre of mass will be at the centre of the shape. If lifting with slings, he will have them placed equidistant from centre, at an angle to each other not exceeding 60 degrees. He will then lift a little, and can tell by the angles from vertical of each sling whether or not the CM is under the centre of the crane cable. If not, he will lower the load, and have someone adjust the sling positions. Having slings equally loaded ensures a level load when lifting, and when a load is level it is a much safer lift than when it tilts one way or the other. A tilt would mean greater force in the sling on the low end. The load could slip out, or the excess force could break the sling.
Q:I am sick and tired of sitting in my room scared looking at a crane fly bouncing around mu walls like its on crack , is there anything i can do to keep the c*nts out
get ur boyfriend or girlfriend to kill threm for you or your besty katy!
