What technologies are used in the thond-ton crawler crane
Crawler crane is widely used in various fields of the national economy of a lifting equipment. With the development of our country's economic construction, the demand for it is more and more large, and the demand for its performance and lifting weight is also more and more high. Driven by the demand of large-scale engineering, China's large-scale crane manufacturing industry has quickly crossed the thond-ton threshold. Here we will specifically introduce, the thond tons of crawler crane used what technology:
1. Dual power system and control technology
In order to meet the requirements of the conventional engine, a double engine is used to provide the power, and each engine forms an independent closed loop.
2. Parallel optimization design technology
It is difficult to optimize the matching of the whole machine because of the complex structure and many combinations of working conditions of the thond-ton crawler crane, the whole machine force system and the bearing characteristics of each component are studied and analyzed in detail, and the whole machine model is established based on the modern numerical analysis theory, to realize a large number of machine parameters optimization processing, the formation of overall parameters and the implementation of optimization technology.
3. Ultra-long boom system technology
The combined jib of the 1000-ton crawler crane is over 200 meters in length, which is super-long and large flexibility. The arm system with variable section and variable wall thickness is optimized, and the technology of double waist rope with length compensation function is studied, which reduces the whole weight of the arm and improves the stiffness of the arm, the utility model solves the problems of lifting stability and operation safety, and greatly improves the bearing capacity of the arm frame.
4. Matching technology of performance and transportation
The performance of 1000-ton crawler crane is very high. The parts need to be bigger, but they need to be smaller to meet the transportation regulations. In order to solve this problem, the small-limit-size, large-capacity slewing bearing, frame, turntable, track frame and other large-scale structural parts are developed, it not only meets the requirements of high lifting performance for the strength of components, but also meets the transportation regulations.
