To analyze the load-bearing characteristics of typical fasteners in the track of gantry crane in railway freight yard,taking a 40.5 t gantry crane as an example,the elastic fastener and gusset fastener commonly used in the track system are studied theoretically and experimentally.Through the stress test of fasteners,the influence law of track lateral force on the mechanical properties of fasteners was analyzed,and the load transfer characteristics of spring-loaded fasteners and pinch-plate fasteners in different braking processes were revealed,thus providing reference for the design and optimization of track system of gantry crane in railway freight yard,and helping to better select and apply different types of fasteners to meet different transportation needs and environmental conditions.
