Product Description

Main Uses

Prevent Turnout Mismoving: Mechanically lock the turnout during maintenance or failure to prevent changes from vibration, wind, or human error.

Interlock System Integration: Serves as a manual emergency locking measure when electrical centralized interlocks (computer or 6502 systems) fail.

Enhanced Driving Safety: Prevents shifting due to icing, heavy snow, or rail deformation in extreme weather conditions.

Usage Scenarios

Maintenance Periods: Essential during inspections to prevent accidental movement when trains pass.

System Failures: Required when electric switch machines or control signals malfunction.

Non-Centralized Areas: Standard safety measure for manual turnouts and non-electrified sections.

Traffic Organization: Used for single-track railways, temporary reverse traffic, and construction zones.

Basic Structure

Lock Hook Part: Holds the turnout tip rail or core rail to prevent movement.
Locking Device: Features a mechanical lock or padlock to prevent unauthorized access.
Fixed Bracket: Available models for rail or sleeper fixation to ensure stability.

Railway turnout hook and lock devices are indispensable safety equipment for maintenance, emergency response, and non-centralized areas.

Frequently Asked Questions

What is the primary function of a turnout hook lock device?

The device is designed to mechanically lock railway turnouts in a fixed position, preventing accidental movement caused by equipment failure, external forces, or human error.

Can this device be used if the electrical interlock system fails?

Yes, it serves as a critical manual emergency locking measure when computer interlocks or electrical centralized systems malfunction, ensuring the turnout remains secure.

Are these devices suitable for extreme weather?

Absolutely. They provide additional safety reinforcement during heavy snow, rain, or icing conditions that might otherwise cause the turnout to shift or deform.

What are the main components of the hook lock's structure?

The basic structure consists of a lock hook part to hold the rail, a locking device (mechanical lock/padlock), and a fixed bracket for mounting on rails or sleepers.

In which areas are hook lock devices most commonly applied?

They are indispensable in maintenance zones, non-electrified sections, stations with frequent shunting operations, and areas requiring temporary traffic organization.

Is the turnout hook lock device certified?

Yes, the device is manufactured under ISO9001 certification, ensuring high standards of quality and safety for railway operations.
