Product Description:

QTZ63(5013B) tower crane tower crane is novel hoisting and conveying machinery which is designed by fully utilizing the group technology, the combinational design technology and the finite element analysis technology and taking the tower crane microcomputer design platform as a tool.
The crane is a horizontal-arm-rest trolley-amplitude upper-revolution hydraulic lifting type crane which has the maximum working amplitude of 56m, the independent lifting height of 40m, the adhesion lifting height of 150m, the rated lifting moment of 710kN•m and the maximum lifting moment of 853.2kN•m. All the performance parameters and technical indexes of the crane meet or surpass national standards.
The crane features advanced parameters, excellent and reliable properties, attractive appearance, high quality, simple and practical structures, advanced safety devices, convenient maintenance, safe usage and reasonable prices, and is ideal construction machinery for many construction enterprises.

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.

Q:HELP! What to do with a thousand paper cranes?
Thread them with fishing line as you stated in you question. Depending on how big they are, string them 20 to a string and put them on a dowel with 10 strings ,so you will have 200 cranes per dowel times 5 dowels !000 pieces.
Q:Can I build a retaining wall off site, and then crane it into position?
If you use precast concrete sections it can be done. You can even have a decorative side if that is required. You might need to have some form of interlocking connections to tie the whole thing together. Depending on its height there might also be a need for anchors to keep it from trying to tip. Without more very detailed information it is difficult to really answer this question. As an example: depending on the type of soil and the height of the wall it is possible to remove the existing wall and install a new one in a day if you use something like a keystone system.
Q:What does the crane mean to the Korean people?
Long Life
Q:type of dc motors used by electric train/subway,crane & fan.give a brief explanation to your answer?
I believe that electric trains and subways use series motors when DC motors are used because the series motor has a torque vs. speed curve that provides high torque at low speed and low torque at high speed. Since power is equal to torque times speed, that is essentially a constant power mode of operation. I believe that mode is selected because it results in a smaller and less expensive complement of power delivery equipment and more efficient operation. Although it has been many years since DC motors were used extensively for cranes, I believe that series motors were used more than other types for the same reasons stated above. However, compound or separately excited motors may have been used for better speed and torque control at low speeds. Except for heater fans in vehicles, I don't believe DC motors have ever been used much for fans. Today, permanent magnet DC motors are used for all of the little motors in vehicles including the radiator fan that was formerly belt driven by the engine. A permanent magnet motor is like a separately excited motor or a shunt motor. The optimum DC motor for a fan would probably be a shunt motor because a fan requires increasing torque as speed increases. Today, computers are cooled by brushless DC motors.
Q:How to understand a Mobile Crane Load Chart?
Hello, Briefly, the structure of the crane or lifting mechanism is not usually the limiting case. The limiting case is to ensure that the Center of Gravity of the mobile crane with the load is such that it is bound within the tires or footprint of the crane. If this load is outside the footprint, the crane tips over.
Q:How do they get big cranes up on skyscrapers for renovation? and how do they bring it down? And where they keep the cranes after done?
Renovation of skyscrapers typically uses a crane, if it has one, that is built up the side of the building, resting on the ground but fastened to the frame periodically for bracing. Tower cranes are built in sections and assembled in place with smaller cranes. To a large extent, renovation of skyscrapers is done from the inside - modifying some of the existing elevators, rather than doing anything from the outside, breaking through the walls to get stuff inside.
Q:When should a crane be load tested?
if crane using regularly more then 8 hrs test should be every 4 months 8 months and full sevice at 12 months............ Load Testing Services ACECO provides inhouse vertical load testing services for load bearing equipment. Examples of equipment that can be load tested: • Below the hook lifting devices • Hoists • Hooks • Testing can be performed to meet ASME B30.20, B30.10, and B30.16 as well as ANSI N14.6. • Standard inhouse 50 ton load testing capacity. • Ability to test higher load capacity devices (Up to 5,000,000 pounds). • Have tested up to 640,000 pounds (320 tons). • Engineering manufacturing available to provide lift fixtures for test purposes. • Can provide nondestructive testing of critical welds and critical locations. • Inhouse capability to make weld repairs using AWS D1.1 qualified procedures and welders. • Calibrated test weights available. • Testing can be performed in accordance with 10CFR50,Appendix B Quality Program. • Certificates of Test and/or Test Reports can be provided. • Can provide onsite load testing services, including supply of calibrated weights.
Q:What is the difference between a jack up tower crane and a fixed tower crane?
Tower cranes, because there is no running mechanism, so tower crane can not do any movement. Fixed tower crane can be divided into the tower height invariant and Jack up. That is, the jack up tower crane is a kind of fixed tower crane.
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
Q:Do cranes, the bird, have any significance in Egyptian or Chinese mythology?
A crane is considered auspicious in China, Japan and Vietnam. It is one of the symbols of longevity and is often represented with other symbols of long life, such as pine, bamboo, and the tortoise. Vietnamese people consider crane and dragon to be symbols of their culture. In feudal Japan the crane was protected by the ruling classes and fed by the peasants. When the feudal system was abolished in the Meiji era of the 19th century, the protection of cranes was lost. With effort they have been brought back from the brink of extinction. Japan has named one of their satellites tsuru (crane, the bird). According to tradition, if one folds 1000 origami cranes one's wish for health will be granted. Since the death of Sadako Sasaki this applies to a wish for peace as well. Also, traditional Chinese 'heavenly cranes' (tian-he) or 'blessed cranes' (xian-he) were messengers of wisdom. Legendary Taoist sages were transported between heavenly worlds on the backs of cranes.
