Main Fatures

TC6520 tower crane is a company based GB/T5031-2008 《tower crane》design and manufacture of a construction crane. It can be applied widely in high-rise civilian building, bridge and water-conservancy project, big-span industrial workshop and high-rise building, etc. the tower crane is high level slewing self-erecting tower crane which adopts horizontal jib and trolley-jib. The main features as follows:

Height of the tower crane is confirmed according to height of building, lifting ability of the tower crane is independent of height.

The tower crane with features as high working speed, stead work condition and high efficiency.

Hoisting jib has 55m or 60m and 65m three ranges. This meets project needs more widely.

The eyeshot of cab is well, and the cab is installed independently,which creat preferable working condition for handlers.

Location of the tower crane is reasonable, and the externality of the crane is beautiful.

Lifting jib adopts rigid double tension bars with features as light structure.

the operation is simple and the maintenance is convenient

Q:How big is the contactor lifting? How big is the car and how big is the turn?: This is not very good answer, the United States originally used Tianshui 213, and then used the Japanese MITSUBISHI, used Schneider, LG, star power, Eaton.

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:would 2 500 ton crawler cranes be able to lift a 854 ton bridge section 80 feet in the air?: Sorry, okorder /... The farther from the center of rotation of the House, the less a crane can lift. That same crane can only lift 57.5 tons at 22 meters from the center of rotation of the House. Ben

Q:Examples of filling and acceptance forms for tower cranes and examples of filling in.: 3 no or no inspection items are completed". In the absence of such or part of the sub - item, it shall be drawn on its serial number".

Q:What are the four major moving mechanisms of a tower crane?: The metal structure includes the tower, the boom and the base. The working mechanism has four parts, lifting, luffing, turning and walking.There are many types of tower crane, if according to whether the walking mechanism, there is a fixed type and operation type; according to the tower structure is divided into rotary, inferior type, attached itself three; if divided by the amplitude, a trolley type, luffing type and folding arm luffing type three; according to the weight division, with light and medium and heavy three.

Q:I read this book recently and i got emotional over it. It relates so much to my life and i think maybe i know what my dad was thinking before he died. I was just wondering what was your reaction after reading this short story?: This book gave me lots of hope. I really loved to hear about Sadako and how she folded so many cranes. I wanted to believe that she would finish the paper cranes and she would get better. When she died in the ending it was very sad. Someone with so much hope and motivation doesn't deserve to die. The book also made me think a lot about why Sadako was sick in the first place. She was only two-years-old when the Americans dropped the bomb on Hiroshima, but she was still eventually killed from it. This book shows the long-lasting effects war has on a country and its people. It really makes you think twice about war. I really enjoyed reading this book. It was an easy read that I had a hard time putting down. Every chance I got I read this book! While it was sad in the end, it was great to hear about Sadako's life and how her friends finished her paper cranes for her. The plot was interesting and exciting. I really like the main character too. Sadako was a very brave, strong person that I wish I was more like. She woke up every day with the will to live and that gave me a lot of hope.

Q:I'd take Denny Crane he's ruthless: Denny Crane

Q:the cable of Crane I creates and angle of 30 degree angle from the horizontal and the cable of Crane II creates an angle of 45 degrees from the horizontal.-draw a figure that gives a visual representation of the problem-write a vector to represent the tension on the cable of Crane I-write a vector to represent the tension on the cable of Crane II-write a vector to represent the 20000 lb cargo container being lifted -calculate the tension on both cables. Justify your answer.....please help me!!! thank you!!!!:): All I can say is.. Big crane make big thing go up.

Q:Many schools I visited claim to teach styles like white crane and even Okinawa/Japanese Karate has come from white crane styles, however I seldom see techniques, kata, forms, or drills that encompass crane concepts of even crane movements. Why is that? At some traditional schools kung-fu/karate it is easy to see the animal influence but at others there is none. Does this also indicate a lack of understanding or incomplete training. What do you think.: Similarly, karate systems like Goju-Ryu and Uechi-Ryu clearly have some of the same movement patterns. Edit: To Internalize proper form and function often calls for a tangible example, like an animal Disagree. People aren't shaped like birds. We've figured out how to do TONS of stuff with our bodies (hit baseballs, high jump, breaststroke, pole dancing, etc) without looking to animal sources. Fighting is no different. Humans fight like humans. If we should look to any animals, it should be other primates, but again, we lack some of the attributes they have. Never seen a gorilla throw a jab, but it's pretty much been acknowledged by numerous sources as the most important punch in fighting, for example.

Q:I am looking for what the breeding season is for sandhill cranes?: Mid-April to mid-June is breeding season for Florida Sandhill cranes lasts from December-June. For most other cranes, like those here in the midwestern U.S., the breeding season is March and April. I'm fortunate enough to live not too far from the Jasper Pulaski Fish and Wildlife Area where the Sandhill Cranes migrate every spring and fall. I always go to see this spectacular event.
