3220 Bolted Rail Clip
Product Overview
3220 Bolted Rail Clip is a robust solution designed to secure medium to heavy-weight rails in demanding industrial environments. With a 150kN (15.2 tonnes) horizontal force capacity, this clip is ideal for cranes, port machinery, and heavy-duty transport systems. Its 17mm horizontal adjustment range and low-profile design ensure precise alignment and compatibility with guide roller-equipped cranes, making it a versatile choice for high-traffic applications.

Key Features
Heavy-Duty Bolted Construction
Constructed from forged steel with an M20 Grade 8.8/10.9 bolt (90mm, Customizable length ) for secure, vibration-resistant attachment to rail supports.
Two-piece design locks tightly when tightened, minimizing lateral rail movement under dynamic loads.
Controlled Clamping & Adjustability
Integral vulcanized rubber block provides consistent clamping force, reducing noise, wear, and fatigue while accommodating minor rail movement.
17mm horizontal adjustment allows fine-tuning during installation or track maintenance, critical for aligning rails in high-precision setups.
Wide Rail Compatibility
Suitable for 33–74.3 kg/m rails across global standards:
Chinese: QU70, QU80, P50
European: UIC 54, UIC 60, 56E1, A65, A100
American: ASCE 80
Two configurations:
(S) with rubber pad: Enhances vibration dampening.
(H) without pad: For direct rail-to-support installation.
Durability & Corrosion Resistance
Galvanized finish and high-strength materials ensure longevity in harsh environments (e.g., coastal ports, mining sites).
Installation & Maintenance
Tighten Grade 8.8 bolts to 200 Nm or Grade 10.9 bolts to 300 Nm using a torque wrench.
Adjust rail position within the 17mm range before final tightening.
Align the clip with the rail and support structure.
Insert the M20 bolt from above or below (no under-access required).
Secure with a special washer and nut, ensuring uniform contact with the rail.
Inspect quarterly for bolt tightness, rubber pad wear, and corrosion.
Replace worn components to maintain clamping efficiency and vibration control.
Applications
Ports & Terminals: Securing rails for container gantry cranes and heavy-load AGVs.
Mining & Heavy Industry: High-traffic ore transport rails and industrial conveyor systems.
Urban Transit & Construction: Light rail systems and temporary tracks for heavy machinery.
Shipyards: Fixation for marine cranes and rail-mounted equipment.
