en.Wedoany.com Reported - The results of the 2026 China Water Transport Port "Digital Intelligence & Low-Carbon Transformation" Green Innovation Practice Case Selection were recently announced. Sany Marine's "Automated Four-Rope RTG Multi-Source Information Perception and Collaborative Control Technology and System" project, implemented at Tianjin Port, stood out among numerous participating cases and won the first prize.

The automation retrofit of four-rope RTGs was once recognized as a technical challenge in the industry—rope swing nonlinearity, complex spreader attitude control, and variable interference from the operating environment have long constrained the improvement of automation efficiency. Sany Marine's self-developed H-Move2.0 system deeply integrates multi-source perception technologies such as GPS high-precision positioning, AI visual recognition, and 3D scanning imaging, constructing a comprehensive, high-redundancy environmental perception system that maintains excellent signal stability under harsh conditions like strong light, rain, and fog at ports. The system also incorporates AI algorithms and digital twin technology, simulating container trajectory and position in real time within a virtual space, intelligently predicting and planning the optimal speed and path for equipment movement. In practical application at Tianjin Port, the operational efficiency of the automated four-rope RTG has steadily exceeded 20 moves per hour, marking the first time in the industry that automated RTGs have substantially surpassed manual operation efficiency.
