Product Description:

 

Technology is the drive for business development and production equipment the assurance of product quality. In the large-scale concentrated production, the stability and uniformity of product quality plays an essential role. The company constantly improves processing equipment. The automatic assembly line ensured quality stability and maximally reduced adverse effect of personal factor to the product quality. As a result, the one-time qualification rate of the products is improved and the company is able to win continuous trust from customers。

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.

The construction hoist product  produced has achieved internationally advanced level in terms of industrial design, control and the drive performance, as well as the operation safety and comfortableness. And is also making efforts to keep improving the product, as what the construction hoist lifts is not only people and material, but also a kind of social responsibility and service concept…
The new generation SC series of construction hoists adopt modular structure, ergonomic design and advanced manufacturing technology, thus the adaptability and reliability of the product is greatly improved, e.g. the max. lifting height can reach 300 meters. The product adopts multiple patented technologies, reaches advanced level in China, and the market share in domestic market is increasing year by year. The product has also been exported to overseas countries like Russia, Turkmenstan, Vietnam, etc. winning the confidence of customers of both home and abroad

1. The cage drive system is equipped with buffering device, so the cage moves more stable.
2. The ergonomically designed cage interior improves comfortableness.
3. The unique structural design has applied for patent.
4. The typical technologies ensure the malposition difference of the guide rail.
5. The excellent parts in the industry ensures reliable quality of the machine.
6. Precise assembly and accurate drive.
7. Professional solutions for special projects.
8. The complete safety devices ensures reliable control system.

Q:How do those cranes that build skyscrapers that go up with the building get back down after it's completed?
The top sections of the mast beneath the crane are removed one at a time and lowered to the ground. The top section of the crane has hydraulic rams that lower it down one mast section at a time. It is hard to describe without a diagram or photos. See photos at attached link. In some design, the jacking portion is at ground level. The crane jacks itself up so a 20' section of the mast can be unbolted and slide out. Then the jack is lowered so the process can be repeated. See second link for photos and a more detailed explanation.
Q:How should we select a appropriate crane for a particular job ?
What is the load weight? How high is the lift? Obstruction, possibly needing a jib? If you are placing a load onto a roof, how far from the edge of the roof is the load going to be placed? How far from the crane pivot is the load on the ground and how far are you going to to move the load away from the crane to place it in position? How close can you get the crane to the load and to the load placement site. The usual scenario is to call a crane outfit and they will ask you these questions over the phone or come to the site and discuss the lift with you. A crane is rated for maximum lift as close, usually 10 feet,to the cab pivot center. As the distance increases, the maximum load that can be lifted, decreases. Our 15 ton crane can pick 15 tons/ 30,000 pounds at 10 feet from pivot center. With the boom fully extended; the boom is 100 feet, at a 30 degree angle, it can pick up only 5,000 pounds. Inside of every crane cab should be a chart that shows the lift capacity at various boom angles and boom lengths. Also is included is a chart for the Jib, if the crane has one. Wingman
Q:1000 paper cranes for japan?
I think it's better to donate money through help Japan on Yahoo! top page or something. Sorry. But paper cranes are not practical help for those who are suffering.

Q:What do crane flies eat?
Crane flies usually don't eat after becoming adults. They usually just breed and die. If they do they would eat nectar. As larvae they eat what most larvae do roots and other vegetation in the soil. 2 0 Comment
Q:Can a crane hook its cables on the front of it,and pick the crane up????????????
No, crane can not lift itself (unless you mean can it pick another crane up, then answer is yes, of course: as you did not ask if the crane can pick itself up) You can also be a 'crane'. You can pick a dog up, maybe the same weight as you!.. but you can not pick yourself up (maybe part of you, like your leg, your arm) there are many different cranes, go to a building site and see (or see the web site I gave you below) Whuch crane you talking about? *Types of crane *Ancient crane *Medieval crane *Railroad crane *Mobile crane *Telescopic crane *Tower crane *Truck-mounted crane *Rough terrain crane *Crawler crane *Loader crane *Gantry crane *Overhead crane *Stacker crane *Floating crane Most NB for crane is its stability (it was found them tipping over): In order for a crane to be stable the sum of all moments about any point such as the base of the crane must equate to zero. In practise the magnitude and combination of anticipated loads is increased so that a crane should have a factor of safety against toppling of about ten times (it is based on leverage) hope it answered you, best regards Desert
Q:Any ideas as to how I can gift 1000 cranes + messages?
3 Aw that is so sweet, maybe you can make a mobile or tie them all on a string. i also really like the scrapbook idea, maybe u can make the cranes small so that they all fit in the scrapbook.
Q:Flocks of cranes shout'. Is it right to use the word'shout' here?
If that's what it sounds like, sure.
Q:how do they make those tall cranes so TALL?
with a taller crane. Some are over 600 feet tall.
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
