Overview

A double girder overhead crane is a type of lifting equipment designed with two parallel girder beams that form the bridge, supported by end trucks on each side. In most configurations, the trolley and hoist travel along a rail installed on top of the girders. This design provides a significant advantage in terms of hook height, as positioning the hoist between or above the girders can add an extra 18 to 36 inches of lift—making it highly efficient for facilities that require maximum overhead clearance.

 

Double girder cranes can be engineered in either top running or under running configurations. A top running double girder bridge crane generally offers the greatest hook height and overhead room, making it suitable for large-scale industrial environments. Because of their robust design, double girder overhead cranes are the preferred solution for heavy-duty applications that demand higher lifting capacities and longer spans. However, the added complexity of their hoist, trolley, and support systems makes them more expensive compared to single girder cranes.

 

These cranes also place greater demands on a building’s structure, often requiring stronger foundations, additional tie-backs, or independent support columns to handle the increased deadweight. Despite these considerations, double girder bridge cranes are valued for their durability, stability, and ability to perform frequent and demanding lifting operations.

 

Commonly used in industries such as mining, steel production, railyards, and shipping ports, double girder overhead cranes are versatile enough for both indoor and outdoor applications, whether in a bridge or gantry setup, and remain a cornerstone solution for handling heavy loads safely and efficiently.

Customized

Custom Lifting Solutions with Quality Assurance

Our double girder overhead cranes can be fully customized to meet specific project requirements. We provide modular crane designs that ensure strong structure and standardized production, while offering flexibility in selecting designated brands for motors, reducers, bearings, and other key parts. To guarantee reliability, we use world-class and top Chinese brands such as ABB, SEW, Siemens, Jiamusi, and Xindali for motors; SEW and Dongly for gearboxes; and FAG, SKF, NSK, LYC, and HRB for bearings. All components comply with CE and ISO standards, ensuring high performance and durability.

Comprehensive After-Sales Services

Beyond design and production, we offer complete after-sales support, including professional on-site installation, routine crane maintenance, and reliable spare parts supply. Our expert team ensures that each double girder bridge crane operates smoothly and efficiently throughout its service life, minimizing downtime and enhancing productivity for our customers.

Cost-Saving Plans for Customers

Considering that transport costs—especially for cross girders—can be significant, we provide two purchase options: Complete and Component. A Complete Overhead Crane includes all parts fully assembled, while the Component option excludes the cross girder. Instead, we supply detailed production drawings so the buyer can manufacture it locally. Both solutions maintain the same quality standards, but the Component plan significantly reduces shipping costs, making it an economical choice for overseas projects.
