Sany 1180 ton crawler crane, track up to 2.4 meters, people standing in front of the giant crane is not worth mentioning.
In November 3, 2009, the largest professional mechanical exhibition in Asia, the tenth Beijing international engineering exhibition, opened, attracting hundreds of well-known domestic and foreign enterprises to compete with the same platform. The Sany group to bring its concrete machinery, road machinery, lifting machinery, mining machinery, piling machinery and other five categories of 47 products exhibition debut. Including the world's first 72 meter arm rack concrete pump car, drilling depth in the world's first SR420 rotary drilling rig, the deepest SH500 continuous wall grab and other products, fully demonstrated the strength of the Sany group in the field of engineering machinery.
Shanghai Sany science and Technology Co., Ltd. is a subsidiary of the Sany group, which is specially responsible for the caterpillar crane business. At the beginning of 2008, it was introduced as the SCC9000 type 900 ton crawler crane called "the first crane in Asia". At the exhibition, they launched the latest development of the SCC11800 type 1180 ton crawler crane, and the world's first SCC6500WE type large tonnage crawler crane (3.0MW wind turbine hoisting), which can lift 120 tons of load to 100 meters.
A thousand ton crawler crane is a big Mac in engineering machinery. It is difficult for the ordinary people to see such a huge machine. Even professional engineers have the privilege to see the spectacle of their work. The number of crawler cranes in Pyramid structure, the greater the hoisting tonnage and the fewer. In particular, a thousand tons of super large crawler crane, only a few countries in the world can be developed, the total output is only a few dozen, scattered in the world's large construction site, so very rare. These giant machines are priced at 100 million yuan more than the annual salary of hundreds of thousands of dollars in hand crane operation, comparable to civil aviation pilots.
Sany SCC11800 type crawler cranes, the maximum lifting capacity reached 1180 tons, equivalent to 6 Boeing 747 aircraft. The maximum lifting torque of 15500 tons m.. The machine weighs 740 tons, with 780 tons of ballast weight, total weight of 1520 tons. The largest single transport capacity is 60 tons. Rectangle truss boom length 42-120 meters, the main arm angle of 30-84 degrees. The design of the jib length of 42-96 meters. The Cummings QSK23 engine, output power of 597 kw. Climbing ability (with basic arm, cab back) 15%. Walking speed of 0.4-1.1 kilometers per hour. It has set a new record for Asian crawler crane.
In the afternoon of November 27, 2009, Guangdong fire power special engineering company successfully hoisted the dome of the 1# 1000MW nuclear power unit of the Fujian Ningde nuclear power station with a Sany SCC9000 type 900 ton crawler crane.
Sany the iron and steel giant, developed by science and technology, weighs only 740 tons of mainframe components, plus weight and accessory equipment, with a total weight of more than 1500 tons, equivalent to the carrying capacity of a train. For the caterpillar crane with 1000 tons or more, it is a great project to load, transport, unload and assemble equipment for the construction of the construction site. The cost of the import and export is often millions, and the transportation and assembly will take several decades.
The assembled SCC11800 crawler crane has two gigantic caterpillar tracks, each of which is 2 meters wide, 2.4 meters high and close to 15 meters in length, consisting of 84 caterpillar tracks. Ordinary people stand on the track before the hand can not touch the edge of the track. The operator to climb 5 meter high cab to operate this machine. The bottom two track is a total width of 13.2 meters, connected with steel beams, constitute the entire crane chassis. The body parts of the crane engine, the hoist, the cab, the crane arm and the weight block are all installed on the turntable, and the body is rotated 360 degrees by the rotary support and the caterpillar chassis. Get off the body by crawler reversible steering. Crane main boom is made of ultra high strength steel, height of over 120 meters, equivalent to 40-50 storey building. In order to balance the load in the car body with the tail weight 250 tons, with 80 tons of heavy vehicle central pressure, each 10 ton counterweight. The maximum lifting load case, the tail of the car but also with a 460 ton load derrick super lifting counterweight. Able to complete most of the construction tasks.
In recent years, with the Chinese economic rise, China in the petrochemical, electric power, iron and steel, construction, transportation infrastructure and other areas in engineering construction climax. While the large-scale crawler crane, is indispensable in the construction of these machines. In the compact time, super large crawler crane and taking "weight for time", so that the project module be maximized, greatly improve the efficiency of construction. For example, in the field of petrochemical industry, our country plans to add more than 2.4 million tons of new oil refining capacity. There are ten oil refining, ethylene and coal chemical projects in the country, and hundreds of new petrochemical units are built. One of the key equipment of hydrogenation reactor weighing more than 1500 tons, the weight reached 2044 tons, ranking first in the world, need 3000 ton crane to lift.
In the field of electricity, the national "draft plan for the revitalization and development of new energy industry" is expected to increase the capacity of nuclear power, solar energy and wind power to 86 million kilowatts, 20 million kilowatts and 150 million kilowatts by 2020. This means that more than 60 million kilowatt class nuclear power plants will be built and tens of thousands of large wind turbines will be built. Each kilowatt class nuclear power unit has nearly 10000 tons of lifting equipment, with a construction period of up to 3-4 years. The nuclear reactor pressure vessel weighs more than 320 tons, and the nuclear island dome weighs more than 150 tons. It is very demanding for the hoisting and hoisting equipment, and it needs a thousand ton crawler crane. In the construction of wind power, there are a number of wind farms in Jiangsu, Jilin, Liaoning, Guangdong, Inner Mongolia, Xinjiang, Ningxia and other places, which have more than 100MW of wind farms. The caterpillar crane is the main equipment of the hoisting construction. The class 3MW wind turbine has more than 70 tons of nacelle weight, and the weight of the tower is over 160 tons. The weight of the impeller is over 40 tons, and it needs to be hoisted to nearly 100 meters above sea level. Today, the largest wind turbine in the world has developed to the 5MW level, with only one leaf blade weighing 18 tons, up to 61.5 meters, which brings great challenges to hoisting.
For a long time, due to the weakness of basic industries, tracked cranes have always relied on imports. In recent years, large-scale industrial construction in China has brought development opportunities for China's construction machinery industry. The crane enterprises, represented by Sany, Xugong, Zhonglian Pu Yuan and Fu dug heavy industry, have developed rapidly, and have developed more than 1000 tons of large cranes, as well as the strength of various types of Engineering cranes, and reversed the adverse situation of the domestic market being monopolized by foreign enterprises. It has made an important contribution to the development of China's industry.
