The development trend of crawler crane
Dec 24,2021
From the development status of crawler crane at home and abroad, it can be seen that crawler crane development trend has the following characteristics:
1.In order to adapt to the needs of large engineering projects, cranes are rapidly developing to large tonnage.
For a variety of large-scale engineering construction, form a complete set of equipment needed for the component, such as the weight also increased, the demand for very large lifting equipment is more and more, in order to achieve the lifting heavy weights, on the basis of the original crane increase super device, not only expanded the work scope of crawler crane, and improve the utilization rate of the crawler crane. At present, the maximum tonnage of crawler cranes has exceeded 1000 tons, for example, the lifting weight of THE CCl2600 of Demag is 1600T, and the LRl1200 of Liebherr is 1200T. With the continuous improvement of the overlift device, the development of larger tonnage crawler crane has become a reality.
2.Core technicalization
Each well-known enterprise has its unique core technology, and continuous innovation, and strive to maintain a leading position in the industry. Now, major companies are making great efforts to research and develop their own core technology, in order to continuously improve their product grade and competitiveness.
3.Intelligence of operation control system
With the continuous development of computer technology and electronic technology, computer control technology and gradually improve integrated sensing technology has been widely used in the crawler crane industry, advanced electronic control and computer operating system configuration has been very popular, Germany liebherr company on very large crawler crane also equipped with global positioning satellite communication system. Various electronic monitoring systems, on-line fault detection and diagnosis during operation, intelligent overall control and so on are the important research fields of crawler crane developing towards intelligent direction in the future.
4.Self disassembly system
Disassembly and assembly performance is an important indicator of crawler crane. Because crawler crane cannot walk freely on the highway and is bulky, it must be disassembled before transportation. When it arrives at the work place, auxiliary cranes are needed for assembly. In order to reduce or eliminate auxiliary crane and save construction cost, it is imperative to develop self-disassembly system. At present, the self-dismantling system of medium tonnage crawler crane has been relatively perfect, but the self-dismantling system of large tonnage is still a difficult problem.
