W220 Rail Clip: Heavy-Duty Adjustable Crane Rail Fixing
The W220 rail clip withstands horizontal forces up to 300 kN (30.6 tonnes), making it ideal for cranes with guide rollers and other ultra-heavy-duty rail systems that demand secure and reliable fixation.
What is W220 Rail Clip?
When heavy rails demand uncompromising strength, GloryRail’s W220/21/43 welded base rail clip delivers. Engineered for the most arduous industrial scenarios, this adjustable clip withstands a staggering 300kN (30.6 tonnes) of horizontal rail force—making it the go-to choice for high-capacity freight yards, heavy manufacturing hubs, and industrial crane systems. Its sleek low-profile build works flawlessly with guide roller-equipped cranes, while welded-to-support installation eliminates the need for below-access—cutting setup time in tight or elevated spaces where traditional fasteners fail.
W220/21/43 Rail Clip Components
| Component Number | Component Name | Key Function |
|---|---|---|
| 1 | Flange Nut | Secures the entire clip assembly, collaborating with the self-tightening mechanism to maintain stability under 300kN loads. |
| 2 | Forging Steel Clip | High-grade forged steel construction resists bending and fatigue in continuous heavy-use industrial environments. |
| 3 | Vulcanized Rubber Block | Applies controlled, scratch-free pressure to the rail while absorbing operational impacts to extend rail lifespan. |
| 4 | Weldable Base | Weldable-grade steel design enables direct attachment to rail supports—no below-access or extra fasteners required. |
| 5 | M20 Captive Bolt | Grade 8.8 captive bolt creates a permanent, secure lock between the clip’s two main components. |
Key Features & Benefits
Field-Tested Globally: Proven in decades of real-world use—from saltwater coastal ports to high-vibration freight lines—with zero compromise on stability.
Welded for Accessibility: Weld directly to rail supports; no need to reach below structures—perfect for elevated tracks or compact industrial layouts.
Dual-Lock Security: Tighten the Grade 8.8 bolt to lock two core parts, plus a built-in self-tightening mechanism that resists loosening under extreme stress.
Rail-Friendly Force: A precision vulcanized rubber block applies controlled pressure—protecting rail surfaces from scratches while absorbing operational impacts.
Adaptable Assembly: Three minimum width options (W/V/U) tailor to your rail size, from compact setups to industrial-scale installations.

Simple Installation & Load Capacity
Welding Guidelines
- Scope: Weld all around the base (except bolt position) with a 5mm throat fillet weld—critical for supporting 300kN loads.
- Key Note: For rails without pads, omit the weld closest to/parallel with the rail (contact us for guidance).
- Electrodes: Use low-hydrogen AWS E7018/E7028 for durable, load-bearing welds.
Torque & Docs
- Tightening Torque: 350 Nm (for M20 Grade 8.8 bolt)—use a calibrated torque wrench for precision.
