Technical Parameters
Structural Design & Installation Adaptability
| Model No. | Shank Design Type | Head Configuration | Thread Specification (if applicable) | Driving End Shape | Installation Hole Diameter (mm) | Sleeper Material Compatibility | Core Structural Advantage |
|---|---|---|---|---|---|---|---|
| DS-12FH | Smooth Round Shank | Flat Head | Non-threaded | Chisel Point | 10-12 | Wooden Sleepers | Low driving resistance; tight fit with wood fibers |
| DS-14RH | Knurled Round Shank | Round Head | Non-threaded | Pyramid Point | 12-14 | Wooden/Composite Sleepers | Knurled surface enhances pull-out resistance |
| DS-16SQ | Square Shank | Square Head | Non-threaded | Conical Point | 14-16 | Concrete Sleepers (with inserts) | Anti-rotation design; stable under lateral load |
| DS-18TH | Threaded Shank | Hex Head | M18 × 2.5 (Coarse Thread) | Tapered Point | 16-18 | Concrete/Steel Sleepers | Threaded connection improves load-bearing capacity |
| DS-20BH | Barbed Shank | Dome Head | Non-threaded | Blunt Point | 18-20 | Heavy-Duty Wooden Sleepers | Barbs prevent loosening in high-vibration environments |
Lifespan Reliability & Failure Mode Analysis
| Model No. | Expected Service Life (Years) | Key Failure Modes | Failure Prevention Measures | Inspection Frequency | Critical Failure Threshold | Reliability Rating (1-10) | Core Reliability Advantage |
|---|---|---|---|---|---|---|---|
| DS-12FH | 8-10 | Pull-out, Shank Bending | Pre-drill matching holes; control driving force | 6 Months | Pull-out force <35kN | 7 | Cost-effective for low-traffic lines |
| DS-14RH | 10-12 | Pull-out, Head Deformation | Knurled shank design; use high-strength material | 8 Months | Pull-out force <45kN | 8 | Balanced reliability for mixed-traffic lines |
| DS-16SQ | 12-15 | Shank Fracture, Sleeper Insert Damage | Square shank disperses load; precision manufacturing | 12 Months | Bending strength <250MPa | 8.5 | Anti-rotation design reduces fatigue failure |
| DS-18TH | 15-18 | Thread Stripping, Point Wear | Coarse thread design; heat-treated point | 15 Months | Thread torque <120N·m | 9 | Threaded connection distributes load evenly |
| DS-20BH | 18-22 | Barb Breakage, Corrosion | Barbed shank with corrosion-resistant coating | 18 Months | Pull-out force <60kN | 9.5 | Barbed design + anti-corrosion treatment extends lifespan |
