Main Applications and Uses

Prevent Turnout Mismoving: Mechanically locks turnouts during maintenance or failures to prevent position changes from human error or external forces.
Interlock System Integration: Serves as a manual emergency locking measure when electrical centralized interlocks (computer or 6502 systems) fail.
Enhanced Safety: Prevents derailment or conflict accidents by ensuring trains enter correct tracks.
Weather Protection: Stabilizes turnout positions during heavy snow, rain, or icing conditions.

Usage Scenarios

Maintenance Periods: Essential for signaling personnel to lock turnouts during inspection and repair.
System Failures: Required when electric switch machines fail or control signals are interrupted.
Non-Centralized Areas: Routine safety measure for manual turnouts and non-electrified sections.
Special Traffic Organization: Used in single-track railways and temporary reverse traffic sections.

Structure and Components

Lock Hook Part: Securely holds the turnout tip rail or core rail to prevent any movement.
Locking Device: Features a mechanical lock or padlock to prevent unauthorized access.
Fixed Bracket: Specialized models can be fixed on rails or sleepers to provide enhanced stability.

Railway turnout hook and lock devices are critical for ensuring fixed turnout positions during maintenance, emergencies, and in non-centralized areas.
