Load's Swing Angle Equation and Structure Parameter for Container Crane Hydraulic Anti-sway System

摘要

The container crane may damp the container swing with hydraulic anti-sway system. The container may be accurately located and promptly placed. To obtain the load's swing angle equation when the crane trolley is stationary after braking for the container crane's hydraulic anti-sway system on the basis of structural characteristic of the anti-sway system and its trolley-load system's moving characteristic and engineering practice. The system's structure Parameter is one of influencing factors on the antisway system's performances when the hydraulic cylinder system's design is accomplished. Through analyzing anti-swing rope's spatial arrangement characteristic and simulating, simulation results show that changing fixed blocks' lateral distance may obviously change the system's structure parameter when the fixed blocks' lateral distance is less than 2.5 m. And changing anti-swing crown blocks' longitudinal distance can not obviously improve the anti-sway system's performances.
