Intelligent Anti-sway System for RMG Spreader

It is a high-precision Intelligent Motion Control System designed and developed for Rail-Mounted Gantry Cranes (RMGs) in railway container stack yards. By using multiple sensors to perceive the Spreader’s dynamic attitude in real time and combining adaptive control algorithms, the system actively suppresses Spreader swing and achieves precise positioning, ensuring that the Spreader’s swing amplitude is stably controlled within ±4 cm during a single pendulum cycle. This effectively enhances the efficiency, safety, and Stability of container handling operations in railway stack yard environments.

Adaptive Anti-Roll Control

Based on the self-developed Intelligent control algorithm, the system can automatically calculate the optimal control command according to the Spreader swing state, running speed, and load condition, thereby achieving stable control of the Spreader swing amplitude within ±40mm during the single pendulum cycle.

Railway Stack yard condition adaptation

In view of the common features of railway stack yards, such as frequent container relocation and alignment loading and unloading, the system supports rapid swing elimination and precise parking, effectively coping with disturbances such as rail unevenness and gusts, thereby ensuring operational accuracy in scenarios such as train loading and unloading and container stacking.

Human–Machine Collaboration and Model Fusion Control

This system provides end-to-end intervention in sway control, supports seamless, disturbance-free switching between automatic and manual modes, preserves intuitive operation, and enhances human–machine collaboration efficiency.
