The "Heavy-Duty Lifting Hub" of Container Flow at Freight Terminals—Cable Reel Powered Double-Girder Gantry Cranes
In the container loading and unloading and yard turnover chain at freight terminals, cable reel powered double-girder gantry cranes are the core equipment supporting "efficient heavy-duty lifting"—from unloading and stacking 20-40 ton containers to loading and shipping, they serve as the "rhythm anchor" connecting various operational links at the freight terminal.

1. Precise Adaptation to Freight Terminal Scenarios
The "heavy-duty + high-frequency flow" requirements of freight terminal containers perfectly match its core characteristics:
The high load-bearing redundancy of the double-girder structure easily handles the rated load of containers (including overweight containers), avoiding structural stress risks during heavy-duty operations;
The gantry crane's large span design can cover the wide operating range of the freight terminal's vehicle parking area and yard, completing the cross-area transfer of containers between vehicles and the yard in a single lift, saving the time spent on multiple transfers.
2. Advantages of Cable Reel Power Supply in Certain Scenarios
For freight terminals with fixed operating radii, cable reel power supply is a more suitable choice: The cable reels in and out synchronously with the crane's movement, eliminating the need for additional power supply tracks and avoiding the risks of cable dragging, wear, and entanglement in the complex environment of a freight terminal; It offers strong power stability, ensuring uninterrupted power supply even during operation, guaranteeing a continuous "unloading-stacking-loading" rhythm for containers during peak hours.
3. Core Support for Freight Terminal Efficiency
Its operating logic perfectly matches the high-frequency operation needs of freight terminals: the cab's field of vision covers the entire operating area, and with precise lifting and luffing control, container positioning and hoisting can be completed quickly; the combination of heavy-duty performance and stable power supply allows freight terminals to maintain a smooth turnover rhythm even during peak freight periods, making it one of the key pieces of equipment for improving the container throughput efficiency of freight terminals.
