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.

- Q:Equipment safety of tower crane
- Safe distance tower and transmission line is not up to the requirements of the tower frame door frame to design, erection principle to power erection, do not use metal materials, bamboo and other materials can be used. The distance between a bamboo pole and a power line shall not be less than 1m, and a certain degree of stability shall be taken to prevent the wind from blowing. The tower crane height and bottom bearing size ratio is large, and the center of gravity of the tower body, high torque, braking frequency, impact force, in order to increase its stability, we will analysis the main causes of the tilting of the tower crane has the following:Overloading. Different types of cranes usually adopts the lifting torque based control, when the amplitude exceeds the rated load weight increase or the corresponding weights, the overturning moment more than stable moment of it, it may cause the collapse of the tower crane.Two, inclined hanging. Slant weights will increase its overturning moment, the lifting point will produce horizontal force and vertical force on the crane, bottom supporting point will produce an additional overturning moment, and the stability coefficient is reduced, resulting in tower crane collapse.Three, the tower crane foundation is uneven, the ground endurance is insufficient, the perpendicularity error is too big, also can cause the tower crane to overturn the moment to increase, causes the tower crane stability to reduce. Therefore, we should proceed from these key factors to strictly check, check and check, and prevent major equipment personal safety accidents. State explicitly eliminated the model should resolutely prohibit the use of, in disrepair, tower crane in the identification of the repair, to limit the use of load, tower crane for the use of fixed number of years there is no uniform standards, opinions vary, different places have different provisions.
- Q:why are siberian cranes endangered?
- Would you spend a winter in Siberia if you could fly south?
- Q:Okay, like a week ago I caught a daddy long legs (a crane fly) in my room with a mug and an envelope and I just left it there, when I removed it there were loads of little black dots on the envelope, I didn't really think about it cos I figured it was the coffee that was inside the mug or something. I got rid of most of them but didn't go out of the way if you know what I mean... And now there are loads of TINY little flies in my room. Could these be baby crane flies? Or something else? And if so how the hell do I get rid of them before they get huge and start reproducing all over again?!
- Crane flies reproduce in summer, but the eggs take 2-3 weeks to hatch, not to mention the time they spend as larvae, so if you caught it last week it doesn't sound like that would be the case. I would call an exterminator to get their opinion.
- Q:Please write in days, hours, weeks, etc.I need math help!!!!
- If it takes 7*60 + 11 = 431 seconds to make 1 crane, then making one million would take 431,000,000 seconds. There are 3600s*24hr*365.25d = 31,557,600 seconds in an average year. Dividing 431 million by this gives a little over 13 years, with a remainder of 20,751,200 seconds. There are 3600*24*30 = 2,592,000 seconds in an average month. So that gives 8 months with a remainder of 15,200 seconds. There are 3600 seconds in an hour, so that gives 4 hours plus 800 seconds. The 800 seconds = 60*13 + 20 = 13 minutes, 20 seconds. This works out to 13 years, 8 months, 4 hours, 13 minutes, and 20 seconds. Though answers can vary depending on how many days you define to be in a year, and how many days in a month.
- Q:this is a little of a random question but why do you think that we should save the crested cranes of uganda? and what do you know about the crested cranes???
- Why shouldn't we? Where do we draw the line when we're responsible for species after species going extinct. Granted, you shouldn't be expected to physically rebuild their habitat yourself if your not up to it; but a small change here or there isn't to much to ask to help save the world, is it?
- Q:im really curious about the 1000 paper crane legend. i went on many different websites to learn about it. one said that you are supposed to have 25 strings to hold the paper cranes (40 each) on it and is that true? also a lot websites said that they used them for weddings so do you have to use them for weddings? or can it be any wish you want? i have a few more questions about it but i will ask whoever seems to know the most about it. thank you:)
- Most people give paper cranes to their love ones who are ill. Since it is a tedious job, they will all help each other in folding it. Shalbi I may be wrong, but I know that to be able to make a wish, you have to fold the cranes yourself. The wish can be anything, but the most common wish is to recover from sickness and have a prosperous life. A crane signifies longevity and fidelity that is why they like to use them on weddings. ^_^
- Q:where can i buy a cheap plush crane machine?
- I bought mine at the candy shop at the mall. it was about $40
- Q:What is the load moment of a crane?
- Cranes are classified according to their tip load of capacity. Moment of a crane depents on its type. Usually moment is calculated by the lenght of its boom multiplied the tip load it carries.
- Q:What is the difference between a tower crane and a jack up tower crane?
- The jack up tower crane is a tower crane (that is an internal climbing tower crane) that is added and reduced by its own special device, namely, the standard section of the tower (that is, the attached tower crane) or the whole climbing tower itself.
- Q:I was wondering if this is possible. The wall we have designed is very close to an existing retaining wall. In order to properly form and waterproof the wall we would have to demo that existing retaining wall. My idea was to build it off site, waterproof it, and then crane it into its location. Is this possible? any similar methods? thanks
- Possible but difficult. You could tell us what the wall is made of? Assuming stone, then you can't lift a stone wall unless you have a steel plate under it, as it will collapse otherwise. That gets complicated. Yes, you could build it with a 1/2 inch steel plate under it, and lift it that way, assuming it is not too long, and crane it into position, but you then have to slide the plate out without cracking the wall, also difficult. The plate is expensive, the crane is expensive. But what do you gain? You still have to demolish the old wall, you still have to build a new one, so what would you gain by building it somewhere else and moving it?
