Recent development characteristics of hoisting machinery: polarization, intelligent technology

large hoisting machinery is an extremely important category in the construction machinery industry. As the name suggests, its main function is to hoist materials. With the development of the times, the specific types of hoisting machinery are becoming more and more detailed, such as truck crane, crawler 4, deformation accuracy: ± 0.5%fs crane, tower crane, gantry crane, truck mounted crane, aerial work vehicle, etc., which belong to the category of hoisting machinery

large hoisting machinery is an extremely important category in the construction machinery industry. As the name suggests, its main function is to hoist materials. With the development of the times, the specific types of hoisting machinery are becoming more and more detailed, such as truck cranes, crawler cranes, tower cranes, gantry cranes, truck mounted cranes, aerial work vehicles, etc., which belong to the category of hoisting machinery

in the process of modern production, hoisting machinery has become an essential equipment. It can effectively reduce the labor force, improve production efficiency and accelerate the pace of social construction. As the most important protection and convenient representative of hoisting machinery, the crane has shown the following characteristics in its development process in recent years:

development of polarization. Many enterprises adopt the constant speed stretching method to test the tensile strength of paper.

the so-called polarization here refers to the simultaneous expansion and development of cranes in both large-scale and miniaturization. In recent years, with the overall rapid development of China's construction machinery, China's crane industry has made a remarkable leap in large-scale. At the 2012 BMW Shanghai Exhibition held last year, Zoomlion exhibited the world's largest tonnage all terrain crane. At the same time, it also created three world records, including the world's first lifting capacity, the world's first boom length and the world's first load driving capacity. XCMG and sany, the other two construction machinery giants in China, have also launched crawler cranes with a lifting capacity of more than 3000 tons

China's construction machinery is particularly attractive in the development of large-scale cranes. The trend of miniaturization is more reflected in foreign crane brands. For example, Komatsu company has successively launched Mini cranes, which integrate the road driving capacity and the special telescopic boom technology. They have the function of tower cranes and can work over roofs and other obstacles

the pace of intelligent science and technology is constantly advancing

the intelligence, science and technology and even more humanization of cranes are also the key points of foreign crane brands ahead of China. With the development of society, more and more cranes are used, and many spaces do not support large cranes to work. Therefore, such a working environment requires the emergence of crane products with special skills or structures. For example, the author once saw an indoor crane, which has nine telescopic arms and can be lifted in a narrow environment. It can be said that the telescopic boom structure has been continuously improved to improve the lifting performance of the machine. For example, Liebherr has introduced ltm1090/2 (90t) and ltm1160/2 (160t) at products (the production and construction are not standardized and misleading), and adopted the oval section main boom equipped with telematik single cylinder automatic expansion system. The oval section main boom has a good effect in reducing the structural weight and improving the lifting performance
