Description
Double girder overhead cranes have all the advantages of single girder cranes. It has a greater lifting capacity than a single-girder overhead crane. The trolley walks along the two main beams and runs more smoothly. The hook is between the two main beams, so the lifting height is high. The end beams are hinged to avoid single-wheel suspension. There are maintenance platforms on both sides to facilitate motor maintenance and trolley maintenance. If you use it frequently, a larger overhead crane is your best choice. Customers can choose from push button, wireless remote or cockpit style hangers.

The structure of double girder overhead crane
The double-girder overhead crane is suitable for various general working conditions and is used for material lifting, equipment installation and maintenance. It is a universal lifting equipment with a wide range of uses. It mainly consists of the main beam, crane traveling mechanism, trolley, cab and electrical equipment.
- Double girder overhead crane adopts the structure of double-girder, double-rail, and single-lift trolley.
- The lifting trolley is equipped with a main lifting mechanism and an auxiliary lifting mechanism, each using an independent transmission system.
- The main and auxiliary lifting mechanisms can complete lifting independently or coordinate to complete the work.

Application of double beam bridge crane
The double-girder bridge crane is mature in technology, safe and reliable, easy to operate and stable in operation. It is a mature product of our company for many years and is the most widely used crane in the world. Double girder bridge cranes are heavy lifting equipment used in a variety of industrial applications. The heavy-duty double-girder bridge crane is a powerful machine used in steel mills, foundries, heavy machine workshops, chemical plants and warehouses with load capacities from 5 tons to 80 tons.
