What is W120 Rail Clip?

GloryRail’s W120/21 is a specialized adjustable crane rail clip engineered to secure heavy rails on narrow supports in the most arduous industrial environments. It delivers exceptional load capacity, withstanding up to 185kN (18.5 tonnes) of horizontal rail force—ideal for compact freight yards, manufacturing plants, and crane rail systems. Its low-profile design works seamlessly with cranes equipped with guide rollers, while welded installation eliminates the need for access from below, simplifying setup in tight or elevated spaces.

W120/21 Rail Clip Components

Component NumberComponent NameKey Function
1Flange NutSecures the assembly, working with the self-tightening mechanism for long-term stability under 185kN loads.
2Clip Cap with Integral Rubber BlockCombines structural support with a built-in vulcanized rubber block—saves space and protects rails.
3M20 Captive BoltGrade 8.8 bolt ensures secure locking of the clip’s two main parts, critical for heavy rail performance.
4Weldable BaseWeldable-grade steel base enables direct attachment to narrow supports—no extra space needed for fasteners.

Simple Installation & Precise Torque Guidelines

Welding Requirements

  • Weld Scope: Weld all around the clip base with a 5mm throat thickness fillet weld (critical for supporting 185kN loads). Note: For rails without pad, omit the weld closest to/parallel with the rail.
  • Electrode Recommendations: Use low-hydrogen electrodes (AWS E7018 or E7028) to ensure weld strength on narrow supports.
  • Custom Guidance: For complex narrow-support setups, contact Glory Rail for personalized welding support.

Tightening & Documentation

  • Tightening Torque: 350 Nm (for M20 Grade 8.8 captive bolt) – precise torque is essential for self-tightening performance.
