The following are the different types of Concrete Sleepers based on different requirements, let us see them together.
1. According to Manufacturing Process
Ordinary Concrete Sleepers
Prestressed Concrete Sleepers
2. According to Reinforcement Diameter
Steel Strand (High-strength steel wire, abbreviated as strand)
Steel Bar (High-strength steel reinforcement, abbreviated as bar)
3. Concrete Sleepers in China
Concrete Sleepers in China are categorized into three types, each suitable for different types of railway tracks:
- Type I Concrete Sleepers
Designed for axle load of 23 tons, maximum speed of 85 km/h, and track density of 1,840 pieces/km.
Suitable for medium and light rail tracks.
Type I concrete sleepers are gradually being phased out on Chinese railway lines due to increased axle loads and traffic volume, leading to increased damage and shortened lifespan.
- Type II Concrete Sleepers
Designed for heavy-duty lines with high load-bearing capacity and frequent repetitions.
Designed for annual traffic volume of 60 million tons, locomotive axle load of 25 tons, freight car load of 23 tons, maximum speed of 120 km/h, and track with 60kg/m steel rails.
Suitable for heavy and medium-heavy rail tracks.
Compared to Type I sleepers, Type II sleepers have improved load-bearing capacity in various sections of the rail profile.
- Type III Concrete Sleepers
Developed to address issues encountered with Type II sleepers on heavy and super-heavy rail tracks.
Type III sleepers come in two forms: with or without shoulders and with lengths of 2.6m or 2.5m.
Designed for locomotive (three-axle) maximum axle load of 23 tons, maximum speed of 160 km/h, and track density of 1,760 pieces/km.
Primarily suitable for super-heavy rail tracks.
