9116 Welded Rail Clip
Product Overview
9116/08/37 Welded Rail Clip is a robust solution designed to secure medium to heavy-weight rails in industrial applications. With a 55kN (5.6 tonnes) horizontal force capacity, this clip is ideal for cranes, port machinery, and material handling systems requiring permanent welded fixation. 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.

Key Features
Permanent Welded Fixation
Full-perimeter welding (except the side parallel to the rail) ensures a rigid, vibration-resistant connection to support structures.
Weldable base made from high-quality steel for reliable 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.
Vibration & Noise Reduction
Integral vulcanized rubber block provides controlled force to the rail:
14mm thickness for rails with pads (S model).
21mm thickness for rails without pads (H model).
Reduces wear and noise in high-traffic environments.
Wide Rail Compatibility
Suitable for 30.03–74.3 kg/m rails across global standards:
Chinese: QU70, QU80
European: A55, A65, A75, A100, UIC 54
Industrial: S30, S41, S49
Japanese: JIS37
American: ASCE 80, ASCE 85
Corrosion-Resistant Design
Galvanized components and weldable steel resist corrosion in coastal, humid, or industrial settings.
Installation Instructions
Welding Procedure
Weld the clip base to the support structure 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 rail movement.
Bolt Tightening
Insert the M16 captive bolt and tighten to 125 Nm torque to engage the self-locking mechanism.
Adjust rail position within the 8mm horizontal range before finalizing welds.
Quality Assurance
Inspect welds for full penetration and no defects.
Maintenance Guidelines
Regular Inspection: Check annually for bolt tightness, rubber pad wear, and weld corrosion.
Rubber Pad Replacement: Replace every 5–7 years or when signs of cracking or deformation appear.
Corrosion Protection: Apply anti-rust coating to welds and bolt threads in harsh environments.
Applications
Ports & Terminals: Securing rails for medium-duty container cranes (e.g., QU70/QU80).
Industrial Facilities: Fixation for assembly lines, warehouses, and material handling systems (e.g., A65/A75 rails).
Mining & Quarries: Light to medium haul rails in surface operations (e.g., S41/S49 rails).
Shipyards: Small to medium crane rails requiring low-profile, welded solutions.
