Bridge cranes are generally composed of three parts: mechanical, electrical and metal structures. The external appearance of the bridge crane is a single-span slab bridge supported on two parallel overhead rails at both ends.

The double-beam bridge crane is an important tool and equipment for mechanization and automation of the production process in modern industrial production and lifting and transportation. Therefore, double-beam bridge cranes are widely used in departments and places such as indoor and outdoor industrial and mining enterprises, steel and chemical industries, railway transportation, port terminals, and logistics turnover.


This machine is divided into two working systems, intermediate and heavy, according to the busyness of use; the intermediate is suitable for machining, metal structure, assembly and other workshops; the heavy is suitable for smelting workshops and the handling of continuous production.
