Overhead Cranes
Double beam overhead crane is a kind of important lifting equipment widely used in industrial fields. It plays a key role in workshops, warehouses, steel plants, etc. And QD bridge crane provides a reliable and efficient solution for lifting and loading and unloading of heavy loads. Its excellent design strongly guarantees the smooth progress of production and logistics operations.
The main structure include main beams, trolley running mechanism, electric trolley, hoisting mechanism, etc.. Two double beams are the main supporting structure. With high-quality steel, it has a solid framework to withstand the great pressure and bending when lifting heavy loads.
The trolley running mechanism is installed at both ends of the bridge. It could drive the bridge crane to move along the plant or dock on the track. This ensues that overhead crane could adjust the operating position within a wide range. The trolley moves on the tracks to enable the hoisting mechanism to be flexibly positioned. The hoisting mechanism is responsible for the vertical lifting and lowering of heavy loads. And it achieves a smooth and safe lifting operation through a precise transmission system and braking device. The electrical equipment provides power for each mechanism of the bridge crane. It also controls its operation accurately, including motors, controllers, limit switches, etc., to ensure the safety and accuracy of operation.
QD bridge cranes are popular in indoor and outdoor industrial and mining sites, iron and steel chemical industry, railroad transportation, ports and terminals, as well as logistic warehouses, and many other fields.
In the workshop of industrial and mining, double beam overhead crane could lift raw materials, semi-finished products and finished products. This could greatly promote the efficient operation of the production process. In iron and steel factories and chemical plants, it can handle heavy equipment, steel and chemical raw materials. For railroad transportation, it can assist in loading and unloading of goods. At port terminals, it is a powerful tool for loading and unloading of goods and realizes lifting and transporting of containers and bulk goods. In logistic warehouses, it can efficiently deal with the storage and transshipment of various kinds of goods.
