Utilizing mainstream frequency converters (Siemens/ABB/Yaskawa) coupled with closed-loop vector control, the system achieves millimeter-level heavy-load positioning. The coordinated control of the hoisting, long-travel, and cross-travel mechanisms ensures smooth acceleration and deceleration curves, effectively suppressing load sway.
2. Multi-Layered Safety Protection Mechanisms
The system integrates overload limiting, overspeed protection, travel limit switches, anti-collision buffering, wind speed alarms, and emergency zero-return functions. Crucially, the safety circuit is independent of the PLC, complying with ISO 13849 PL d or SIL 2 safety standards.
3. Intelligent Anti-Sway Algorithm
Based on input shaping technology and adaptive fuzzy PID, the system controls load sway angles to within ±0.5° without the need for mechanical anti-sway devices. This significantly enhances hooking efficiency and operational safety.
4. Remote Monitoring and Data Management
Equipped with standard Industrial Ethernet interfaces (Profinet/EtherNet/IP), the system allows for seamless integration into user MES or WMS platforms for centralized data management.
5. Energy Efficiency and Low Maintenance
The frequency conversion feedback unit regenerates electrical energy during lowering or deceleration phases back into the grid, achieving comprehensive energy savings of 15%~30%. Additionally, the use of non-contact sensors and solid-state relays significantly reduces the number of wearable parts.
