Rail movement joints with longitudinally moveable asymmetrical switches
Rail movement joints with longitudinally moveable asymmetrical switches
Rail movement joints in this design consist of completely clamped stock rails and longitudinally moving asymmetrical switches. Their design principle corresponds with that of a switch device therefore no check rails are required for this design. The gauge widening in the different positions is minimal. This design can also be used for curved tracks up to R = 350 m.
Advantages
- Proven and economical solution for medium-length movements
- Suitable for standard fastening systems
- Overrunning in both directions at track speed possible
- High wear allowance
