Abstract

This study examines a port crane securing system. A securing system, often referred to as a tip-over prevention device, prevents cranes from overturning caused by strong winds or typhoons, and this tie-down system is attached to each leg of a crane and designed to withstand wind speeds of up to 50 m/s. Conventional crane securing systems are frequently identified as challenging and time-consuming to install. However, this study proposes a securing system applied with an automated tie-down system that overcomes these shortcomings. The proposed securing system that utilizes an automated tie-down mechanism is designed to replace the manual tie-down method with a self-fastening mechanism to prevent the crane from overturning, capsizing, and slipping due to typhoons and strong winds and to ensure structural safety. A combination of geared motors and springs were used in the upper and lower securing points to achieve automatic fastening. Furthermore, this study was able to ensure the stability and reliability of the securing system by verifying the proposed system's structural integrity through structural and dynamic analyses using software.
