- Foamed aluminum plate
- Lower steel baseplate
- Leveling shim
- A composite rail pad (carbon fiber-reinforced polymer layer + rubber damping layer) is installed between the rail and upper baseplate.
Performance Characteristics:
- Low vertical static stiffness (~21 kN/mm)
- Excellent elasticity for effective vibration absorption
- Optimized for impact energy dissipation
Application:
Designed for heavy-haul, high-frequency operating conditions.
DTVI1 Fastening System:
Structural Features:
- Utilizes arched elastic clips for rail retention
- Replaces conventional rail seats with gauge-adjustment blocks
- Transmits lateral forces to sleeper shoulders
Performance Characteristics:
- Enables track gauge adjustment
- Maintains track geometry stability
- Restricts longitudinal/lateral rail movement
Application:
Primarily deployed in switch and crossing areas (S&C zones).
DTVI2 Fastening System:
Structural Features:
Elastically detached fastening system consisting of:
Steel baseplate
Elastic clips
Plate I & II
Gauge shims
Spike bolts
Short sleepers
Heavy-duty spring washers
Nylon sleeves
Leveling shims (for vertical adjustment)
Performance Characteristics:
- Large gauge adjustment capacity (±16mm)
- Enhanced elasticity for monolithic trackbeds
- Bolt-free clip design reduces maintenance
- Accommodates post-construction adjustments
Application:
- Main applications:
- Underground line monolithic trackbed switches
- Elevated track formations
