Pre-stressed Concrete Sleepers

concrete-sleeper
  • Duraset Sleepers are manufactured with 60MPa concrete, reinforced with high tensile prestress wires. This enables the sleeper to perform even under the most adverse railtrack conditions
  • The 1:20 built-in cant provides proper rail-to-wheel contact, ensuring optimum performance
  • Cast-in shoulders ensure consistent, accurate track gauge
  • Pandrol elastic rail fastening system provides a reliable clamping force
  • High sleeper mass provides greater track stability
  • Re-usable due to its long life span
  • Gauge widening facility reduces wear on wheels and rails
  • Our Quality Management System is ISO 9001:2000 certified
  • Low profile shoulder reduces derailment damage
  • 10-tonne system pad has an upstand that replaces the loose GPI
  • Rotate pads to achieve gauge widening
  • Pads on 5- and 10-tonne systems eliminates rail seat abrasion and is necessary to maintain the clamping force
  • Pre-assembled and delivered as a captive system
  • Less waste through loss of loose components
  • Easy to install

WHY DO WORLD CLASS MINES ONLY USE DURASET CONCRETE SLEEPERS?

  • Rolling stock remains on the track
  • Reduced rail track maintenance
  • Improved rolling stock efficiencies
  • Reduced maintenance on rolling stock
  • Improved tramming safety
  • Improved flow of men, material and rock
  • Improved bottom line profitability
  • Our Quality Management System is ISO 9001 :2000 certified

HOW DO DURASET CONCRETE SLEEPERS BENEFITWORLD CLASS MINES?

  • Cast-in steel shoulders ensure a constant, fixed gauge, reducing the chances of a derailment
  • Pandrol spring steel clip fastenings offer a constant, fixed clamping force
  • High sleeper mass maintains track geometry – essential for smooth rides and low rolling stock maintenance
  • Built-in 1:20 cant provides excellent wheel to rail contact
  • Duraset concrete sleepers are absolutely essential for superior rail track construction

A SUPERIOR DURATRACK WILL REDUCE:

  • Maintenance costs
  • Labour requirements
  • Accidents
  • Working capital.

A SUPERIOR DURATRACK WILL INCREASE PRODUCTION THROUGH:

  • Improved availability of rolling stock
  • Efficient face cleaning
  • Timeous delivery of men and material
