Overview

The VPM Swing Nose Clamp Lock is engineered for superior safety and reliability in rail applications. With the capability to provide positive locking and clamping of the swing nose simultaneously, it effectively eliminates the risk of derailment. This innovative locking solution has been tested under extreme conditions and is endorsed by some of the world’s largest rail networks, including SNCF for high-speed operations. 

Key Features

The VPM is designed to withstand high-speed operations with a nose crossing speed of up to 560 km/h

Adaptable to various installations, including cast cradles or built-up common crossings, and compatible with all types of bearers—wooden, concrete, metal, and slab tracks. 

Features such as a mechanical back drive and electric heating (optional) enhance performance and reduce maintenance needs. 

Complies with NF F 52-163 and NF F 52-164 safety standards and is recommended by UIC for high-speed lines.

Operation

The VPM operates through a four-phase maneuver that ensures precision in locking and unlocking: 

  1. Initialization: The swing nose is locked by the left-hand square head and wedged by the right-hand square. 
  2. Unlocking: A movement of the drive rod facilitates the unlocking of the left-hand square head. 
  3. Swing Nose Movement: The translational motion of the square results in movement of the swing nose. 
  4. Re-locking: The drive rod's motion re-engages the left-hand square head into the wedging chamber. 

Position and locking status are monitored by integrated clamp lock detectors, ensuring high reliability even under challenging conditions. 

Applications

The VPM Swing Nose Clamp Lock is designed for high-speed rail lines, metros, and heavy haul operations, making it a versatile choice for a range of railway projects.
