AI Technical Summary
Existing gantry cranes are prone to movement and affect stability when the rail wheel braking system fails in windy weather.
A quick-windproof device including two parallel stop seats is adopted. The track wheel is fixed and its width is adjusted by the spacing adjustment structure and the longitudinal expansion structure. The track wheel is stably positioned in windy weather by using the cooperation of the adjusting screw and the threaded sleeve.
It effectively prevents the gantry crane from moving in windy weather, improves the stability of the equipment, and adapts to the positioning requirements of different track widths.
