In recent years, the rapid development of the national economy has boosted the pace of urban construction. The modern high-rise buildings make the faces of big cities change with each passing day. According to the latest report, China has been the largest country in the world for more than 200 meters of high-rise buildings in 9 consecutive years. With the exuberant demand of high-rise buildings, modular construction has also been rapidly popularized, and construction work is further demanding. The tower crane with flexible boom and super lifting capability has obvious advantages, and has become an indispensable equipment for modern high-rise building construction.
It is understood that with the step of urbanization, the land resources are becoming more and more precious, the land use rate is getting higher and higher, and the construction area of the large and middle cities is becoming smaller and narrower. At the same time, compared with the traditional construction, the suspended load of modular construction is larger and heavier. These challenges are a great challenge to the tower crane with large installed capacity, especially in high-rise construction. In contrast, the super large diesel power and hydraulic powered brachial tower crane not only has large weight, but also has a short balance arm and its own power. It has been proved to be the "great king" of the hot high-rise building.
At present, domestic super capital boom tower crane is basically monopolized by foreign capital and Taiwanese capital brand, but its price is relatively high, which greatly increases construction cost. In order to break through this situation, as the leading enterprise of equipment manufacturing, ZOOMLION, which integrates the strongest R & D team in the field, tackles hard, breaks through the key technical problems of the super large boom tower machine, takes on the important task of making the major hoisting equipment domestically made, and has the world's most advanced global creeping LH335 0-120 is coming to the waves.
The powerful man should shoulder the responsibility of refreshing history
As a global high-end equipment manufacturer, ZOOMLION has been engaged in the research and development of tower cranes for more than 60 years. It has organized and undertaken national key issues and presided over the development of industry standards. The company not only has the most authoritative tower machine technology center in China and the largest tower machine laboratory, electrical laboratory, the largest electro-hydraulic fatigue test bench in Asia tonnage, but also the largest single tower manufacturing base in the world. The company's product share ranks first in the domestic tower crane market. With its strong product development capabilities and reputation, ZOOMLION has become a leader in technology research and manufacturing.
The LH3350-120 tower machine independently developed by ZOOMLION adopts the key technology of the industry leading "diesel power, electro-hydraulic proportional control, hydraulic drive", and the product is more safe, intelligent and reliable. LH3350-120 selects the design and manufacturing technology of the hoist arm of the high strength steel variable cross section tower, which makes the lifting arm lightening to the international advanced level and greatly improves the lifting performance of the tower. Its electronic control liquid drive control technology ensures the control of the tower mechanism to be more energy-saving and environmentally friendly and safe and stable; the arm rear tilting flexible refusal device and its piece In order to ensure the safety of the tower structure, the safety of the structure of the tower can be ensured, the flexibility and the safety and reliability of the tower are ensured, and the jacking system technology is used in the inner climbing oil cylinder to achieve a more safe, efficient and intelligent lifting operation of the tower. The key technologies have been applied for 12 patents, including 10 invention patents.
ZOOMLION LH3350-120 is the largest tonnage tower crane in China at present. It is also the largest tonnage crawling tower crane in the world. The maximum lifting torque is 33 million 500 thousand nm, and the maximum lifting capacity is 120 tons, equivalent to 17 adult elephants at the same time.
At present, the LH3350-120 tower has entered the late stage of research and development. It is believed that its birth will be a new breakthrough in the development of construction equipment. It provides strong technical support for the modular construction of the high-rise buildings, the hub of the airport, the exhibition halls, the theaters, the water conservancy and hydropower and so on. At the same time, it will break the monopoly of the super large arm tower crane with foreign brands in the large domestic projects, and further improve the influence and competitiveness of the Chinese brand in the field of the global tower.
