What precautions should be taken when installing Rubber Rail Pads?
Before installing rubber rail pads, prepare the track bed by ensuring it is clean, level, and properly drained. During installation, pay close attention to precise positioning and alignment to avoid gaps and ensure even stress distribution. Tighten fasteners to the correct torque specifications and follow all safety precautions for the installation area.
| Rubber Rail Pad | ||
| Technical Parameter | Unit | Value |
| Stiffness | KN | 90-130 |
| Hardness Shore A | ℃ | 72-80 degree |
| Electronic Resistance | Ω | ≥ 106 |
| Tensile Strength before Aging | Mpa | ≥12.5 |
| Elongation before Aging | % | ≥250 |
Pre-installation preparation
- Clean the surface: Thoroughly remove all debris, dirt, sand, and oil from the sleeper and rail base before installing the pad.
- Ensure the surface is level: The installation surface must be flat and free from any unevenness that could affect performance or create gaps.
- Check drainage: Make sure there is proper drainage to prevent water accumulation, which can deteriorate the pads.
- Consider cold weather: In cold temperatures, verify the pad remains flexible and does not become brittle, as a stiff pad will not conform to the surface properly.
Installation and alignment
- Position the pads accurately: Install the pads with precise positioning. Lateral deviation should not exceed 0.5 mm, and longitudinal deviation should not exceed 1 mm.
- Maintain flatness: The final track flatness should meet specific standards (e.g., 1 mm per 10 meters) to prevent gauge variation and uneven forces.
- Lubricate contact areas: For specific applications like crossings, lubricate the contact areas between the pad and the rail to aid in seating and alignment.
Fastening and safety
- Torque fasteners correctly: Tighten rail fasteners according to the manufacturer's specifications. Insufficient torque can lead to loosening, while excessive torque can deform bolts.
- Follow safety protocols: Close the work area to all other traffic to ensure the safety and speed of the installation.
- Use proper tools: Use specialized installation tools or equipment to ensure accurate placement and handling of the pads.
