Description

QD double-girder overhead traveling crane is popular lifting equipment in many industries. It is mainly for lifting heavy work-pieces and goods in factories or warehouses. This type of bridge crane is known for its sturdy structure, large lifting capacity and good operating performance.  It consists of two parallel main beams, which are the key parts supporting the entire crane structure. These two main beams are made of high-strength steel. Compared with single-beam, double-beam designs offer better stability and load-bearing capacity, making them suitable for heavier loads. The two main beams are connected to the end beams at both ends, and the crane travels along runway beams mounted on the building columns. And its electric trolley moves laterally on the main beam, while the entire overhead crane moves longitudinally along the track. Thus, it is capable of covering a large working area.

Due to its strong load-bearing capacity and flexibility, double girder overhead traveling crane is suitable for handling large or heavy objects, such as large mechanical parts, steel materials, etc. It is a popular using equipment in many industries.

Application

• Automotive: To lift and move heavy parts such as engines and frames in assembly lines.
• Steel industry: Handling raw materials, semi-finished steel, and finished coils or plates in steel mills.
• Port terminals: Loading and unloading cargo from container ships, and handling heavy objects in and out of warehouses or yards.
• Mechanical processing: Transporting large machine tools, molds, and other heavy mechanical equipment within factories.
• Warehousing logistics: Storage and retrieval of materials in large warehouses, especially heavy or oversized items.
