1. Core Strategy Combining Active Control and Mechanical Optimization

To effectively reduce crane load swinging, a three-level control system must be established. First, at the operational level, gradual acceleration control is recommended, with an acceleration range of 0.1 to 0.3 meters per second squared, combined with an S-shaped speed curve. Second, the mechanical system should be optimized with a composite damping solution consisting of hydraulic buffers and wire rope dampers. Finally, the electronic control system should integrate PID algorithms with a response time of less than 500 milliseconds and machine vision positioning technology with an accuracy of ±1 centimeter. Additionally, the lifting rigging system should be optimized by reducing the hook height and adopting a four-rope anti-swing layout to form a stable three-dimensional structure. Regular laser track calibration should also be performed to ensure errors are controlled within 3 millimeters per meter. This solution can significantly reduce swinging by over 80% under normal working conditions.

2. Systematic Approach with Intelligent Upgrades and Full-Process Management

A comprehensive prevention system covering the environment, equipment, and personnel must be established. For environmental management, a real-time wind speed warning system should be implemented, issuing alerts when wind speeds exceed 10.8 meters per second, along with indoor wind barriers. Equipment maintenance should follow standardized procedures, including daily oil pressure checks, monthly wire rope condition tests, and quarterly sensor calibrations. Personnel training should utilize VR simulators for assessments, requiring operators to control swinging within 2 degrees. Furthermore, an LSTM neural network-based prediction system can be deployed to analyze historical data and enable proactive intervention 300 milliseconds in advance. Combined with magnetorheological dampers featuring a response time of less than 50 milliseconds, this forms a complete intelligent anti-swing closed-loop system. This solution is particularly suitable for precision lifting scenarios such as nuclear power applications, achieving millimeter-level positioning accuracy.
