Main Uses
🛡️
Prevent the turnout from mismoving
During maintenance, construction or abnormal operation, the hook lock device can mechanically lock the turnout to prevent position changes due to equipment failure, human error, or external forces like vibration and strong wind. This prevents derailment and conflict accidents.
🔗
Used in conjunction with the interlock system
Serves as a manual emergency locking measure during electrical centralized interlock faults (e.g., computer or 6502 systems) to ensure fixed turnout positioning.
⚠️
Enhance driving safety
Ensures turnout stability during special weather conditions like heavy snow, ice, or track deformation.
Usage Scenarios
🔧
Maintenance and Construction
Mandatory locking during inspections to prevent accidental movement when trains pass or personnel are working.
⚡
Interlocking System Failure
Manual installation when electric switch machines fail or control signals are interrupted.
🛤️
Non-centralized Interlocking Areas
Standard safety measure for manual turnouts and non-electrified sections.
🚦
Special Traffic Organization
Used for temporary reverse traffic or construction-related slow-moving sections requiring reinforced stability.
Basic Structure
🔹
Lock hook part: Holds the turnout tip rail or core rail securely.
🔹
Locking device: Mechanical lock or padlock to prevent unauthorized access.
🔹
Fixed bracket: Rails or sleeper-mounted options for maximum stability.
Railway turnout hook and lock devices are important safety equipment to ensure the fixed position of turnouts, especially indispensable in maintenance, emergency response to faults and non-centralized interlocking areas. Correct use can effectively prevent traffic accidents and is one of the core measures of railway safety management.
