Clamp Lock VAE TEMPFLEX
Self-regulating clamp lock VAE TEMPFLEX
The clamp lock is a mechanical device for setting turnouts and locking and securing switchblades and crossings with movable points.
It locks the closed switch and the stock rail by a positive connection, but also fastens the open switch in its position.
The setting movement of the clamp lock is carried out by a switch machine or a manual switch-throw mechanism which engages in the slide rod of the lock.
The slide rod is electrically insulated in the middle by bolted and/or glued synthetic parts.
Large turnouts with long switches are set and secured by various clamp locks.
The movement of these locks is coordinated. The setting movement is transmitted with mechanical rods or with hydraulic systems. But it is also possible to equip each clamp lock with a switch machine of its own.
The clamp lock is a safe and proven setting and locking system for turnouts and belongs to the standard equipment of many railways all over the world.
It is used in switch devices of turnouts and for crossings with movable points.
Advantages
- Not affected by gauge widening
- Self-regulating - no influence of longitudinal displacements of the switches caused by temperature changes on the functioning of the lock
- No transmission of vibrations of the switch to the slide rod
- Trailable
- Compatible with a wide range of switch machines
Technical characteristics:
| Max. trailing speed | 40 km/h |
| Admissible change of length of the switch due to temperature changes | +/- 35 mm |
| Rail sections | For all common rail sections |
| Gauges | Can be used irrespective of gauge |
