Concrete
Sleepers
Specially designed for underground applications
CRITICAL INSTALLATION PROCEDURES 2
FISHPLATES
Transfer dynamics forces.
Use male and female fishplates.
- Install fishplates with arrows pointing upwards.
- Install female fishplates on the inside of the rail
GAUGE WIDENING FOR 10 TONNE SLEEPERS
- Always install sleeper with upstand in the correct position.
- A 25mm Super Elevation on curves will alleviate and tear on rolling stock wheels and rails.
CRITICAL INSTALLATION PROCEDURES 1
TRACK PANEL
- Compact footwall sloping 1:20 towards the drain
THE STRONG FOUNDATION
- Use graded, washed ballast 37.5mm to 53mm in size
Ballast
The resilient support
- Only tamp directly beneath the rail seats leaving loose ballast underneath the middle of the sleeper.
- Ballast around heads of sleepers.
- Ballast up to 30mm below the flange of the rail.
Water
The resilient support
- Use flolok drains to keep water away from the track panel.
- Top of drain sections must be below the elevation of the sleeper base.
CRITICAL INSTALLATION PROCEDURES 3
- Always use a carry handle when moving sleepers.
- Use Pandrol tools for safe and easy installation of concrete sleepers.
- Ensure that the pad is correctly on the railset to protect the sleeper against abrasion.
- Remove the polystyrene inserts and Mineclips.
- Insert the Panlifter into the shoulder.
- Lift the handle to clamp the sleeper to the rail.
- Push the rail down onto the railseat with the Panlifter, while installing a Mineclip on the opposite shoulder.
- Insert the heel of the Mineclip into the shoulder at a 45° angle.
- Position the installation tool around the outer arch of the Mineclip.
- The Mineclip should remain at 45° angle.
- Initially position the installation tool around the outer arch of the Mineclip while ensuring that the Mineclip remains at a 45° angle to the rail.
- Insert the Mineclip as shown.
- Using a hammer, tap the Mineclip into position. A final blow to secure.
- The Mineclip is correctly installed when the front of the clip protrudes just past the shoulder.
- The Pandrol installation tool facilitates safe and proper installation of the Mineclip.
Extraction procedures for track maintenance
- Use the handle of the installation tool as an extraction tool.
- Place the tapered side of the shoulder. Ensure that the clip catcher is in position on the opposite side.
- Dislodge the Mineclip by tapping the Extraction tool at the opposite end.
- The clip catcher will prevent the clip from flying out and eliminate the risk of injury.
