For outdoor gantry cranes, normal travel brakes are not always enough to resist storm-level wind loads. High-wind safety typically requires dedicated securing devices such as rail clamps, top-of-rail brakes, wedge-type storm brakes, wheel brakes, and sometimes storm pins/tie-downs depending on crane design and local rules. These devices are intended for static holding under wind force, not routine travel deceleration.
A key requirement is fail-safe behavior: many storm securing systems are designed to engage on power loss, which is essential because storms often bring electrical instability. Wind-safety systems are usually integrated with operational procedures and interlocks (e.g., anemometer alarms, parking logic, travel inhibit).
Selection depends on rail profile, wheel arrangement, crane mass, rated wind speed, and corrosion exposure. The most robust approach is a layered system: travel brakes for operation plus dedicated storm brakes/rail clamps for parking and typhoon securing.
