The rail-mounted container gantry crane is an efficient lifting equipment used in container yards. Its structure mainly consists of a gantry, trolley running mechanism, lifting mechanism, and trolley running mechanism. The gantry is made of a box-type beam structure, offering high strength and rigidity, capable of withstanding heavy loads and wind loads. The gantry running mechanism allows the crane to move longitudinally along the track. The lifting mechanism is responsible for the vertical lifting of containers, while the gantry running mechanism facilitates the horizontal movement of containers along the gantry beam. The rail-mounted container gantry crane is equipped with an advanced automation control system, enabling precise positioning and efficient operation.
The structural design of the rail-mounted container gantry crane also focuses on stability and safety. The gantry is supported by two parallel legs and an upper crossbeam. To meet different yard requirements, the span of the rail-mounted crane is adjustable, typically covering multiple container lanes. The lifting mechanism is driven by steel ropes or chains and is equipped with a double hook system. This crane can handle either one 40-foot or two 20-foot containers simultaneously, significantly improving operational efficiency. The electrical system uses frequency conversion control technology, ensuring smooth start-up, precise positioning, and reduced energy consumption. The rail-mounted container gantry crane can also be integrated with the yard management system for fully automated operations, further enhancing yard operational efficiency and intelligence.
Used for the efficient loading, unloading, storage, and transshipment of import and export containers, supporting high throughput operations. It improves port logistics efficiency and meets the rapid loading and unloading requirements of large vessels.
At rail freight stations, it enables fast container transfer between rail and road transport, optimizing multimodal transportation processes, improving cargo transshipment efficiency, and reducing transportation costs and time.
Supports the storage, scheduling, and distribution of large containers, meeting the operational needs of modern logistics and enhancing overall supply chain efficiency.
