Double Girder Gantry Crane for Liftling Containers in the Train Station
This equipment is commonly found in railway container centers and freight hubs. It can be linked with trains, container trucks, and yard shelves to form a full-process logistics system of "railway transportation - road transshipment - warehousing and stacking".
Technical advantages of container loading and unloading:
1. Efficient operation and precise positioning:
◦ The crane adopts the linkage control of the three mechanisms of "lifting - trolley operation - trolley operation". The typical operation cycle (lifting box - translation - dropping box) takes ≤2 minutes, and the average daily operation volume of a single gantry crane can reach 300~500TEU (20-foot standard container).
◦ The lifting device is equipped with a laser positioning system, which achieves a positioning accuracy of ±100mm by scanning the relative coordinates of the container corner fittings and the target position (such as train carriages and truck carriages), avoiding manual positioning errors.
2. Safety protection and reliability design:
◦ Multiple safety protections: ◦ Lifting weight limiter (alarm when overloaded by 10%, forced shutdown when overloaded by 15%), lifting height limit, operating stroke limit, windproof anchor device (wind resistance level ≥6, wind resistance ≥10 when shut down).
◦ The driver's cab is equipped with a shock-absorbing seat and panoramic glass windows, equipped with air conditioning and heating and cooling systems, and cameras are installed in blind spots to improve operational safety.
◦ Structural durability:
◦ The surface of the main beam and the outrigger is shot blasted for rust removal + three layers of paint (primer + intermediate paint + topcoat), with a total dry film thickness of ≥200μm, which is suitable for rain, salt spray and other environments in open-air cargo yards; the wire rope is lubricated regularly (once every 50 hours), and the service life is ≥1000 cycles.
3. Intelligent and automated upgrades:
◦ Integration of some high-end models: ◦ Anti-sway system: The container swaying is suppressed through torque compensation or variable frequency speed regulation, and the swing amplitude is controlled within ±0.5 meters;
◦ Remote control: The driver can operate through video monitoring and remote control handles in the ground control room to reduce the risk of high-altitude operations;
◦ Internet of Things monitoring: Equipment status data (such as motor temperature, bearing wear, and operation time) is transmitted to the management platform via 4G/5G to achieve predictive maintenance.
The double-beam gantry crane at the railway station plays a key role of "bridging the upstream and downstream" in container railway transportation through professional structural design and intelligent control. Its efficient, safe and precise operating characteristics ensure the smooth connection of railway container logistics and are an indispensable core equipment for modern railway freight hubs.
