A Lever Box with Pull Rod is a mechanical device used in railway signaling and track control systems. It is designed to operate switches, signals, or other track components from a distance, allowing railway operators to control the movement of trains and the alignment of tracks safely and efficiently.
Key Features of Lever Box with Pull Rod:
- Construction:
- Lever Box: The lever box is typically made from durable materials such as steel or cast iron, providing robustness and resistance to weather conditions. It contains a series of levers that can be operated manually.
- Pull Rod: The pull rod connects the lever box to the switch or signal. It transmits the mechanical force from the lever to the component being controlled.
- Design:
- The lever box contains multiple levers, each corresponding to a specific track switch or signal. When a lever is pulled, it engages the pull rod, which moves the switch or signal.
- The design may include a locking mechanism to prevent accidental operation and ensure safety.
- Usage:
- Track Switching: Lever boxes are used to operate track switches (points) that change the direction of trains on the tracks. Operators can change track alignment from a distance, improving safety and efficiency.
- Signal Control: They can also be used to control signaling devices, ensuring that trains receive the correct signals for safe operation.
- Installation:
- Lever boxes are typically mounted at strategic locations along the railway track, allowing operators easy access to operate the levers.
- The pull rods are connected to the relevant switches or signals, with proper alignment and secure fastening to ensure effective operation.
