What is the e2055 railroad clip?
The E2055 railroad clip is a specific type of high-strength, U-shaped elastic rail clip, part of the versatile Pandrol e-Clip family, used to securely fasten steel rails to railway sleepers (ties) for heavy-duty track applications, providing essential tension and stability against train forces and thermal movement. Made from hot-forged spring steel, these clips offer high fatigue life and are a standard component in ballasted track systems with wood or concrete ties, ensuring consistent rail alignment.
| Item | Diameter | Material | Weight | HRC Under pressure | Fatigue test |
|---|---|---|---|---|---|
| E2055 | ø20 | 60Si2MnA, 60Si2Cr, 55Si2Mn, 38Si7 | 0.80 kg | 44-48 | ≥950kg 5000000 times without breaking |
- Type: An "E-type" elastic rail clip, known for its iconic 'e' shape.
- Material: Forged spring steel (like 60Si2MnA) for strength and durability.
- Function: Clamps onto the base of the rail to hold it firmly to the sleeper/tie plate, preventing longitudinal movement.
- Application: Used in ballasted track, suitable for heavy-haul railways and various sleeper types (wood, concrete).
- System: Often used as part of a complete fastening system with rail shoulders, pads, and insulators.
- Performance: Offers high clamping force and excellent fatigue resistance, with hardness typically around 44-48 HRC.
What is the maximum pressure-bearing capacity of the E2055 rail clip?
The E2055 rail clip's pressure capacity is typically defined by its toe load, which is around 500-700 Kgf (kilogram-force), but under fatigue testing, it withstands forces of ≥950kg for millions of cycles, or achieves clamping forces of ≥2,950 lbs (about 1300 kg) at specific deflections, indicating high durability and bearing strength.
Key Specifications:
- Toe Load: Often cited as 500-700 Kgf.
- Static/Proof Load: Can withstand ≥950kg (approx. 2094 lbs) without breaking in fatigue tests.
- Clamping Force (Deflected): ≥2,950 lbs (approx. 1338 kg) when deflected to 7/16″.
- Fatigue Life: Designed to last 3-5 million cycles without failure.
- These figures show the E2055 clip's robust design, combining high static holding power with excellent fatigue resistance for long-term railway application.
Function and features of E2055 Rail Clip
1.Secures rails: As a spring clip, the E2055 is designed to exert continuous, self-tensioning clamping pressure on the base of the rail, holding it firmly in place.
2.Maintains track stability: It plays a crucial role in preventing the lateral and longitudinal movement of rails, which is vital for the integrity and stability of continuously welded track.
3.Absorbs stress: The clip's robust spring steel construction allows it to withstand and absorb the significant dynamic forces and vibrations that occur during train operations.
4.Durable and low-maintenance: It is designed for a long service life with minimal need for manual adjustments or torque checking, offering a "fit-and-forget" solution.
5.Versatile applications: While known for its use in heavy-haul lines that experience intense loads, the E-clip system is adaptable for a wide range of railway applications, including metro, high-speed, and conventional tracks.
6.Easy installation: The E2055 clip is installed by being driven parallel to the rail, a process that can be done manually with standard tools or with mechanized equipment.
