Recently, the Qingdao Municipal People's Government officially released the Decision on the 2025 Qingdao Science and Technology Award. The project "Fully Autonomous Key Technologies and Applications of Motion Control Systems for Automated Rail-Mounted Gantry (RMG) Cranes," jointly developed by Shenzhen INVT Electric Co., Ltd. and Qingdao New Qianwan Container Terminal Co., Ltd., along with several other partner units, was awarded the Second Prize of the Qingdao Science and Technology Progress Award!

The Qingdao Science and Technology Award is the highest municipal science and technology award established by the Qingdao Municipal Government. For 2025, the Second Prize of the Municipal Science and Technology Progress Award was conferred upon only 63 achievements citywide. Previously, INVT's technologies related to automated RMG cranes won the First Prize of the Science and Technology Award from the China Ports & Harbors Association in 2024. Winning this municipal science and technology award marks dual authoritative recognition from both the port industry and the municipal government, fully validating the technical innovation level and practical engineering value of INVT's solution.

1. Tackling Core Technologies to Achieve Autonomous Control

For a long time, the core electrical control systems, drive devices, and control algorithms of domestic automated RMG cranes relied heavily on imports. This dependency resulted in high procurement costs, supplier lock-in for maintenance services, and difficulties in system iteration, which restricted the low-cost intelligent upgrading of traditional container terminals.

Addressing this shared industry challenge, the INVT project team focused on core research aimed at localization and autonomy for port hoisting equipment, achieving a series of core technical breakthroughs with independent intellectual property rights. The project innovatively developed multi-drive synchronization and dynamic anti-skewing technology for wide-span RMG cranes, resolving the long-standing issue of equipment skewing during high-speed operation. Additionally, the team developed encoder redundancy fault-tolerant control technology, enabling seamless switching under sensor fault conditions and significantly reducing unplanned equipment downtime. Leveraging an online identification algorithm for hoisting motor parameters, the system adapts to complex terminal operation scenarios involving heavy and variable loads, improving overall machine operational accuracy and stability.

2. Deployed at Qingdao Port: Creating a Replicable Benchmark

Currently, this technology series has been deployed on a large scale at Qingdao Port. Its core value lies in breaking foreign monopolies, establishing complete independent intellectual property rights, effectively enhancing terminal operational throughput efficiency, and delivering significant energy savings and operational gains. The project has accumulated multiple independent intellectual property rights, leading the engineering application of fully autonomous control systems for RMG cranes.

This achievement offers a replicable and scalable technical blueprint for the intelligent construction of traditional domestic ports. Against the backdrop of growing demand for localized replacement of legacy port equipment, this technical solution balances cost-efficiency with reliability, providing a valuable practical model for smart port construction and the self-reliance of the port-maritime equipment supply chain in China.

3. Deepening Independent Innovation to Empower Industry Upgrading

Receiving this award represents a milestone in INVT's long-term commitment to independent core technology innovation. It reflects the company's strategic focus and forward-looking vision through sustained, high-intensity R&D investment in industrial automation. INVT stated: "Taking this award as an opportunity, we will continue to focus on core sectors such as ports and smart logistics, increase R&D investment, deepen collaborative innovation among industry, academia, research, and application, accelerate technical iteration and large-scale deployment, and continuously empower the high-quality development of high-end port equipment industries."
