• Prevent Mismoving: Mechanically locks the turnout to prevent position changes due to equipment failure, human error, or external forces like vibration and strong wind.
• Interlock System Integration: Serves as a manual emergency locking measure during electrical centralized interlock faults.
• Enhanced Safety: Provides additional security in non-centralized areas or during special weather conditions like heavy snow or rain.

• Maintenance and construction periods for personnel safety.
• Electric switch machine failures or control signal interruptions.
• Manual turnouts and non-electrified sections.
• Special traffic organizations like temporary reverse traffic or slow-moving sections.

• Lock Hook: Securely holds the turnout tip rail or core rail.
• Locking Device: Features a mechanical lock or padlock to prevent unauthorized access.
• Fixed Bracket: Enhances stability by fixing onto rails or sleepers.

Railway turnout hook and lock devices are essential safety equipment for maintaining fixed turnout positions. They are indispensable during maintenance, emergency fault responses, and within non-centralized interlocking areas. Proper utilization effectively prevents traffic accidents and remains a core measure of railway safety management.
