Crane refers to a range of vertical lifting and carrying heavy loads of multi- level action lifting machinery . Because of China's construction machinery industry is extremely competitive, especially international construction machinery giant inroads into the Chinese market , such as Caterpillar , Komatsu and so on. Compared with foreign competitors , our business in terms of product categories, research and development, technical level, the scale of capital and brand influence and so there is a large gap. Crane domestic enterprises to fully recognize the current status of the industry, and actively explore innovation, increase scientific and technological research , enterprises in product innovation.
Maanshan learned from the power company , the company developed a miniature mobile crane special vehicles have passed the national qualification examination certification, the crane is being applied for national patents.
According to reports, miniature mobile cranes using hybrid gasoline and electric power , to move through the track mode , the load range , staff can work the remote control for lifting three tons or less .
The crane applications, can effectively solve the problem of safe lifting small space , with a small footprint lifting large lifting capacity , operational safety and other features . In the actual grid maintenance and construction process , the lifting GIS components , transformers , surge arresters, insulators and isolation switch operating mechanism , widely used in large cranes can not expand the narrow spaces indoor job .
