Özet

Portal cranes used in ports are subject to significant safety risks under severe wind and storm conditions due to their large surface areas, high centers of gravity, and exposure to open environments. When out of service, sudden and excessive wind loads may cause uncontrolled rail movement, derailment, overturning, and severe loss of life and property. Existing wind safety systems predominantly employ friction-based braking mechanisms, whose effectiveness may be compromised by power loss, hydraulic failure, or insufficient braking capacity.

The primary objective is to develop a hybrid wind safety system incorporating mechanical locking and hydraulic actuation for 50-ton-class portal cranes. The proposed system integrates a mechanical locking mechanism that restrains crane movement along the rail with a hydraulic mechanism for lock disengagement during normal operation. Thus, the system is designed to maintain a safe locked position under abnormal conditions, including hydraulic or power failure.

Wind forces, braking forces, and overturning moments will be determined under various wind speeds and loading conditions in accordance with FEM 1.001 and ISO 4302 standards. The system will be modeled using SolidWorks and structurally analyzed in ANSYS to evaluate stress, deformation, and strength. Analytical and numerical results will be compared with relevant literature and standards to assess reliability and applicability.

The originality lies in integrating mechanical locking and hydraulic actuation into a unified hybrid safety approach. The study is expected to establish a validated design framework for enhancing portal crane safety under wind conditions and provide a technical basis for prototype development and industrial applications.
