What Technologies Are Used In The 1000-Ton Crawler Crane
Nov 12,2021
The crawler crane is a kind of lifting equipment widely used in various fields of the national economy. Driven by the demand for large-scale projects, China’s large-scale crane manufacturing industry quickly crossed the threshold of kilotons.
What technologies are used in the 1000-ton crawler crane?
1. Dual Power System and control technology
The 1000-ton crawler crane requires high power and working reliability of the engine. In order to realize that the conventional engine can meet the requirements, the dual engine is used to provide power, and each engine forms an independent closed circuit. The dual-engine dual hydraulic system and control technology are studied. The dual-engine or single-engine is used according to the actual demand, when the two systems are working at the same time, they can automatically adjust according to the power required to ensure that the two engines provide the same torque at the same speed, so that the two engines can work in balance without causing a bias load of one engine.
2. Concurrent optimization design techniques
The 1000-ton crawler crane has many working conditions, complex structure, and difficult to optimize the whole machine matching. In order to solve the parameter optimization problem of the whole machine, the load-bearing characteristics of the whole machine force system and its components are analyzed in detail, and the whole machine model is established based on the modern numerical analysis theory, a large number of machine parameters to achieve the optimal processing, the formation of overall parameters and the implementation of optimization technology. This technology is convenient to determine and optimize the parameters of each component, reduces the weight of each major structural component, and shortens the product development cycle.
3. Super Long Boom System Technology
The 1000-ton crawler crane combined boom is over 200 meters in length, which is a super-long flexible boom. The stability and safety of the boom and working condition need to be solved. The boom system with variable cross-section and wall thickness is optimized, and the double waist rope technology with length compensation function is studied, which reduces the whole weight of the boom and improves the rigidity of the boom, the utility model solves the problems of the stability of the jib and the working safety, and greatly improves the carrying capacity of the jib.
4. Matching technology for performance and delivery
The performance of the 1000-ton crawler crane is very high, the components need to be large, but to meet the transport regulations, the size of the components to do small. In order to solve this contradiction, a slewing bearing with small limit size and large bearing capacity has been developed, and large structural components such as frame, turntable, and track frame have been separated, it not only meets the requirements of high lifting performance for component strength but also meets the transportation regulations.
By using these technologies, the power and working reliability requirements of the 1000-TON crawler crane engine are solved, the problem of optimizing the parameters of the whole structure is solved, and the problems of the stability of the starting arm and the working safety are solved. The utility model solves the requirement of high lifting performance for component strength. The 1000-ton crawler crane has the advantages of high reliability, high safety, and high lifting performance.
