9120 Rail Clip: Heavy-Duty Adjustable Crane Rail Clip

Glory Rail’s (9120/15/38) 9120 Rail Clip is a high-performance welded base rail clip engineered exclusively for heavy rails in the most demanding industrial settings. It delivers exceptional strength, withstanding up to 120kN (12.2 tonnes) of horizontal rail force—ideal for freight yards, ports, and manufacturing hubs. Its low-profile design works seamlessly with cranes equipped with guide rollers, while the welded installation eliminates the need for access from below, simplifying setup in tight or elevated spaces.

9120 Rail Clip: Proven Features for Maximum Heavy Rail Stability

  • Global Reliability: Successfully used worldwide for years, ensuring consistent performance in harsh environments (e.g., high-vibration freight lines, coastal ports).
  • Welded Base Convenience: Clips are welded directly to rail supports—no access from below needed, cutting installation time in hard-to-reach areas.
  • Dual Locking Mechanism: Two main parts lock securely when tightening the Grade 8.8 bolt, plus a built-in self-tightening design prevents loosening under extreme vibration.
  • Protective Rubber Block: A special vulcanized rubber block (integrated into the clip cap) applies controlled force to the rail, avoiding surface scratches and absorbing minor impacts.
  • Wide Rail Compatibility: Designed to fit more rail types than illustrated—contact Glory Rail for full compatibility details for your specific rail.

Simple Installation & Load Capacity

9120-rail-clip-installation

Welding Requirements

  • Weld Scope: Weld all around the clip base (except the side closest/parallel to the rail) with a 4mm throat thickness fillet weld.
  • Electrode Recommendations: Use low-hydrogen electrodes (AWS E7018 or E7028) to ensure weld strength and durability.
  • Continuous Weld Option: If a full continuous weld around the base is needed, contact Glory Rail for customized technical guidance.

Tightening & Documentation

  • Tightening Torque: 350 Nm (for M20 Grade 8.8 captive bolt) – critical for proper locking and self-tightening performance.
  • Full Instructions: To get step-by-step installation documentation tailored to your project, reach out to our technical team directly.
