Swing Nose Crossing
1. Brief Description :
-
A swing nose crossing or moveable point frog is a device used at a railway turnout to eliminate the gap at the common crossing
(a.k.a. frog) which can cause damage and noise.
Swing Nose Crossing has high comfort level and is used for continuous movement of rolling stock over gapless tracks. It is used for reduction in jerks and enhances life cycle of wheel and crossing.
Swing Nose Crossing has flexible moving points and has special bolting. This crossing is free from defects and gives best performance.

2. Advantages :
-
Continuous wheel overrunning area (no running edges and head surface interruptions), therefore particularly suitable for
high-speed and heavy haul traffic, as well as for mixed operations (different vehicles and wheel set types).
No check rails required - thus ideal for high-speed traffic.
Reduces airborne and structure-borne noise.
Highest possible service life due to absence of impacts in the wheel transition area. Thus ideal for heavy haul, high speed operations.
3. Features :
- No flaws
- Reliable
- Accurate Performance
