Container gantry crane
Lifting capacity: Typically 40–65 tons (capable of lifting 20–40-foot containers, including loaded containers), with some large models exceeding 100 tons, suitable for ultra-large containers. Span and lifting height: Spans range from 18-50m (larger for track-mounted models), with lifting heights of 12-30m, enabling multi-tier stacking (typically 4-8 layers) to enhance yard utilization. Work class: Most are A6-A8 class, capable of handling high-frequency continuous operations (average of over 16 hours per day), meeting the “24/7” operational requirements of ports. Operating speed: Lifting speed 8-30 m/min, trolley travel speed 20-50 m/min, crane travel speed (tire-mounted 10-20 km/h, rail-mounted 30-50 m/min), efficiently matching container turnover efficiency. Specialized and efficient: Equipped with telescopic container-specific lifting equipment (capable of automatic container alignment and rotation), with a short single-cycle operation time (30–60 seconds per container), significantly improving loading and unloading efficiency. High Space Utilization: Through multi-layer stacking design, the storage density of containers in the yard can be increased by 3-5 times, saving land resources. Automation Compatibility: Modern models support semi-automatic/fully automatic operation, integrated with GPS positioning, laser ranging, and anti-sway systems, enabling unmanned operations, reducing labor costs, and improving accuracy.
