Double girder overhead crane is one of the important types of lifting equipment widely used in different industries. It plays a key role in workshops, warehouses, steel mills, etc. And this general double girder overhead crane provides a reliable and efficient solution for lifting, loading and unloading heavy loads. Its superior design guarantees smooth production and logistics operations.

Main Structure

The main structure includes main beams, trolley traveling mechanism, electric trolley, hoisting mechanism, etc. Two double beams are the main supporting structure. With high quality steel, they have a strong frame that can withstand high pressure and bending when lifting heavy loads.

Working Mechanism

The trolley travel mechanism is on both ends of the bridge. It can drive the overhead crane along the factory or dock along the rails. This allows the overhead crane to adjust its working position over a wide range. The trolley moves along the rails, which allows flexible positioning of the lifting mechanism. It is responsible for the vertical lifting and lowering of heavy loads. This ensures smooth and safe lifting thanks to a precise transmission system and a braking device. The electrical system provides power to each mechanism of the overhead crane. It also precisely controls its operation, including motors, controllers, limit switches, etc., to ensure safe and accurate operation.

Applications

QD overhead travelling cranes are popular in indoor and outdoor industrial and mining facilities, in the chemical industry, ferrous metallurgy, railway transportation, ports and terminals, as well as in logistics warehouses and many other areas.

In the workshops of industrial and mining enterprises, double girder overhead crane can lift raw materials, semi-finished products and finished products. This can greatly contribute to the efficient operation of the production process.

For steel and chemical plants, it can move heavy equipment, steel and chemical raw materials. In rail transportation, it can assist in loading and unloading goods. At port terminals, it is a powerful tool for loading and unloading goods, lifting and transporting containers and bulk goods. In logistics warehouses, it can effectively handle the storage and transloading of various types of goods.
