Abstract: Gantry cranes play a vital role in outdoor material handling operations; however, the progressive deterioration of their braking performance over time elevates the risk of wind-induced sliding. Conventional methods for assessing wind resistance often lack dependable field validation and advanced measurement techniques. This study introduces an innovative approach that combines simulation with instrumentation to evaluate gantry cranes in operational conditions. A multi-body dynamic model incorporating both rigid and flexible leg components was developed using ANSYS and ADAMS software. This model quantitatively characterizes the relationship between wind velocity and supporting reaction forces, while accounting for uneven load distribution across different leg types. An equivalent wind load model was formulated to link measurable hydraulic cylinder thrust to theoretical wind loads, incorporating load proportionality coefficients derived from comprehensive simulations across diverse crane geometries. Sensitivity analyses identified ground roughness exponent and static friction coefficient as the primary parameters affecting model accuracy. Building upon this framework, an intelligent detection device was engineered, featuring dual hydraulic cylinders with synchronized pressure and displacement control, achieving displacement measurement accuracy within 10 mm over a 100-meter span. The system integrates real-time wind sensing to adjust for ambient environmental conditions. Field experiments conducted on two distinct gantry cranes (100/32 t and 30.5 t 20 m) confirmed the model's validity, establishing their wind resistance thresholds at 43.5 m/s and 48.7 m/s, respectively. This research offers a practical and precise methodology for on-site wind resistance evaluation, substantially improving the safety and operational reliability of gantry cranes by effectively bridging the gap between theoretical modeling and empirical verification.
