Hollow Steel Sleepers
Hollow steel sleeper in track with hot-box detector
The hollow steel sleeper in the turnout offers the opportunity to install the hydraulic setting system HYDROSTAR® and the rods of conventional monitoring systems in the protected hollow sleeper.
In the track, hot-box and hot-wheel detectors can be placed in hollow steel sleepers.
Advantages
Hollow steel sleeper, optimised design by finite element analysis
- Sensitive parts of the setting system, the lock and the monitoring device as well as other elements can be placed safely in the hollow steel sleeper
- Components are protected against being damaged by ballast
- Continuous tamping is possible
- Optimized design by FE analysis
- In case of electrical heating good heat conduction because of the closed structure
Technical characteristics:
| Design of the hollow sleeper | Bent and welded from steel sheets and equipped with covers |
| Rail fastening | Suitable for all common rail fastenings |
| Plates | Electrically insulated bolting |
| Electrical heating | Possible |
| Width | Similar to standard sleepers taking into consideration that elements are placed in the sleeper |
| Coupling | Coupling in pairs possible |
