Steel Sleepers
Steel sleepers are used for standard railway tracks and turnouts subjected to medium or heavy axle loads. They are lightweight and dimensionally more accurate than wooden or concrete ones. Their multiple advantages, including lower cost compared to wooden sleepers, make them an effective technical solution for modern rail networks.
RTT offers a wide range of steel sleeper designs, including ones for heavier axle loads and higher speeds.
Production: RTT’s Steel Sleepers are manufactured in accordance to specific technical requirements of customers. The manufacturing process, employing latest CAD / CAM systems to design and optimise production, is optimally structured to reduce wear and lower forces, maintenance and life-cycle costs.
The sleepers are cut to length; the ends pressed in a forging die. Depending upon the type of fastenings specified by the client, holes are punched or base plates / shoulders are welded onto the steel sleeper.
| Technical Characteristics |
| Rail fastening for low track load | Directly by means of clips and t-bolts |
| Rail fastening for higher loads | Base plate welded to sleeper tops and used with elastic rail clip or hook in shoulders with fast clip / elastic rail clips |
| Electric insulation | On request by means of bolted plastic pads or insulators with rubber pads |
The principle benefits of RTT’s steel sleepers are:
• Improved stability
• Fully recyclable
• Reduced maintenance
• Uniform and consistent quality
• Can be supplied in small batches
• Time and cost savings at installation
• Simple site preparation and installation
• Minimal “Imprest” stock requirement
• Convenient during accident and flood restorations
• High resistance to lateral displacement in ballast
• Ideal solution for sharp curves and steep gradients
• Environmental benefits due to reduced ballast requirement
• Lightweight design enabling easy handling
• Equally amenable to both manual and machine tamping
• Can be laid on inferior ballast such as sand or gravel albeit with appropriate speed restrictions
