9216 Welded Rail Clip
Product Overview
9216 Welded Rail Clip is a premium solution designed to secure heavy-weight rails in the most arduous industrial applications. With a 165kN (16.8 tonnes) horizontal force capacity, this clip is ideal for cranes, port machinery, and mining systems. Its 8 mm horizontal adjustment range and low-profile design ensure compatibility with guide roller-equipped cranes, while the self-tightening mechanism guarantees long-term stability under high vibration and load.
Installation Guide
Welding Procedure
Weld the clip base to supports with a 4mm throat thickness fillet weld using low-hydrogen electrodes.
Omit welding on the side closest and parallel to the rail to allow for thermal expansion.
Bolt Tightening
Insert M16 captive bolt and tighten to 125 Nm torque to activate the self-locking mechanism.
Adjust rail position within the 8mm horizontal range before finalizing welds.
Quality Assurance
Inspect welds for full penetration and compliance with ISO 3834 standards.
Maintenance Guidelines
Annual Inspection: Check bolt tightness, rubber pad wear, and weld corrosion.
Rubber Pad Replacement: Replace every 5–7 years or at signs of cracking/deformation.
Corrosion Protection: Apply anti-rust coating to welds in harsh environments.
Applications
Ports & Terminals: Heavy container cranes (e.g., QU80/QU100 rails).
Mining & Quarries: High-load haul rails in underground operations (e.g., ISCR120, GCR183).
Steel Mills: Rail-mounted heavy machinery (e.g., A120 rails).
Shipyards: Marine cranes requiring permanent, vibration-resistant fixation.

Key Features
Permanent Welded Fixation
Full-perimeter welding (except rail-parallel side) ensures a rigid, vibration-resistant connection to support structures.
Weldable base constructed from high-strength steel for superior load distribution.
Self-Tightening Mechanism
Two-piece design locks securely when the Grade 8.8 bolt is tightened to 125 Nm torque, maintaining consistent clamping force over time.
Vibration & Noise Control
Integral vulcanized rubber block reduces wear and noise:
14mm thickness for rails with pads (S model).
21mm thickness for rails without pads (H model).
Wide Rail Compatibility
Suitable for 37.2–183.06 kg/m rails across global standards:
Chinese: QU70, QU80, QU100, QU120
European: A75, A100, A120
Industrial: ISCR80–ISCR120, GCR183
Japanese: JIS50N, JIS60
Corrosion-Resistant Design
Galvanized components and weldable steel resist corrosion in coastal, humid, or industrial environments.
