How to determine the required quantity of rail clips?

 The rail elastic clips (also called rail clip, elastic rail clip )are used with railway sleeper to fasten rails on both sides. The rail clips are usually made of forged spring steel, which are manufactured by hot forging process. The forged rail clips are considered to be better than other metal forming process due to most uniform microstructure.

For meeting various needs of clients, GNEE RAILWAY RAILWAY supplies E-clips, PR clip, SKL clips, Russia rail clip, Deenik clip, Nabla spring blade, KPO rail calmp, gantrex rail clips, fast clip, crane rail clip and other special clips for rails. We have proffesional production cline to design and manufacture standard rail clips or nonstandard clips. welcome to as.

To determine the required quantity of rail clips, calculate the total length of the rail, determine the correct clip spacing based on load and rail deflection, and then multiply the total length by the number of clips per unit of length (e.g., per meter or kilometer). For specific applications like cranes, estimate the horizontal load and choose a clip strong enough to handle it, using engineering standards and consulting manufacturers for precise calculations and spacing recommendations.

1. Determine total length and estimate clips per kilometer

• Calculate the total length of the rail required for your project.

• Use a standard guideline for the number of clips per kilometer. A common figure for railway lines is about 7,000 clips per kilometer.

2. Calculate clip spacing for your specific application

• Estimate loads: If not provided, estimate the horizontal force on the clip by multiplying the vertical wheel load by a factor (e.g., 15% for crane applications).

• Calculate rail deflection: Determine how much the rail deflects between clips to minimize lateral movement and prevent the rail pad from shifting.

• Determine spacing: Calculate the correct clip spacing, or use best practices. A common maximum spacing guideline for crane rail clips is around 600mm, but this depends on the specific application.

3. Choose appropriate clips

• Select a clip style (e.g., welded or bolted) and ensure it is rated for the estimated horizontal loads.

• Verify that the clip's dimensions are compatible with the specific rail profile being used.

4. Calculate the final quantity

• Multiply the total length of the rail by the number of clips per meter or kilometer to find the total quantity needed.

• For a single sleeper and single rail, 2 sets are needed. For a single sleeper and two rails, 4 sets are required.

5. Account for additional factors

• Consider extra clips for curves, switches, and other specific areas where greater support is needed.

• Order a small percentage of extra clips to account for any damage or future replacements.
