Product Description

Main uses
1. Prevent the turnout from mismoving
During maintenance, construction or abnormal operation, the hook lock device can mechanically lock the turnout to prevent the turnout from changing position due to equipment failure, human error or external forces (such as vibration, strong wind).
Prevent trains from entering the wrong tracks to avoid derailment or conflict accidents.
2. Used in conjunction with the interlock system
When there is a fault in the electrical centralized interlock (such as computer interlock, 6502 electrical centralized), it can be used as a ** manual emergency locking measure ** to ensure the fixed position of the turnout.
Provide additional safety guarantees in non-centralized interlocking areas (such as hand-operated turnouts) or during shunting operations in the station yard.
3. Enhance driving safety
In special weather conditions (such as heavy snow or heavy rain) or when the track condition is poor, prevent the turnout from shifting due to icing, deformation and other reasons.

 

Usage scenarios
During the maintenance and construction period
When maintenance and signaling personnel inspect and repair turnouts, they must use hook-lock devices to lock the turnouts to prevent other personnel from making mistakes or the turnouts from moving when trains pass by.
2. When the interlocking system fails
When the electric switch machine for the turnout fails, the control signal is interrupted or the interlocking system malfunctions, a hook lock device needs to be manually installed to ensure the correct position of the turnout.
3. Non-centralized interlocking area
In manual turnouts, non-electrified sections or stations where shunting operations are frequent, hook-lock devices can be used as a routine safety measure.
4. Special traffic organization
For instance, in single-track railways, temporary reverse traffic, construction slow-moving sections, etc., additional reinforcement of turnout positions is required.

 

Basic structure
Lock hook part: It holds the turnout tip rail or core rail to prevent movement.
Locking device: Usually a mechanical lock or padlock to prevent unauthorized personnel from unlocking.
Fixed bracket: Some models can be fixed on rails or sleepers to enhance 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.
