Rail Clamp Fastening System
The Railway Clamp is a forged steel fastener that secures rails to sleepers in traditional track systems. Its simple offset head design allows rapid hammer installation without special tools. The smooth shank penetrates timber fibers, creating friction-based holding power. Made from low-carbon steel with optional galvanized coating, this economical clamp remains widely used in mine tracks, industrial sidings, and temporary construction railways where modern elastic systems are unnecessary.
Technical Specifications:
| Parameter | Standard Value | Option |
|---|---|---|
| Material | Low carbon steel | Q235 / A36 |
| Shank diameter | 16 mm | 14 – 19 mm |
| Length | 140 mm | 125 – 165 mm |
| Head shape | Offset dog ear | Round or square |
| Point shape | Chisel | Wedge |
| Surface | Black oiled | HDG |
| Hardness | HRB 70 – 85 | As forged |
Installation & Maintenance Perspective:
- Offset head directs hammer force straight down the shank axis.
- Chisel point splits wood fibers without causing major cracking.
- No pre-drilling needed for most softwood sleeper applications.
- Skilled worker drives over four hundred clamps per eight-hour shift.
- Removal uses standard claw bar for quick rail replacement.
Maintenance & Operational Perspective
- Compressed wood fibers create radial pressure around embedded shank.
- Head overhang presses rail base firmly against sleeper surface.
- Vertical lift resistance depends on timber density and condition.
- Lateral forces from curving trains are partially resisted by friction.
- Wet or decayed sleepers significantly reduce clamp holding ability.
