3120 Bolted Rail Clip
Product Overview
3120 Bolted Rail Clip is a high-performance solution designed to secure medium to heavy-weight rails in industrial environments. With a 75kN (7.6 tonnes) horizontal force capacity, this clip offers robust fixation for cranes, port machinery, and material handling systems. Its 17mm horizontal adjustment range and low-profile design ensure compatibility with guide roller-equipped cranes while accommodating rail misalignments during installation or thermal expansion.

Key Features
Robust Bolted Construction
Constructed from Q235/Q345 forged steel with a Grade 8.8/M20 bolt (length varies by application) for secure attachment to rail supports.
Two-piece design locks into place when tightened, resisting vibration and heavy impacts.
Controlled Clamping Force
Integral vulcanized rubber block applies consistent pressure to the rail, reducing noise, wear, and fatigue while allowing minor rail movement.
17mm horizontal adjustment enables precise alignment in high-traffic or dynamic environments.
Wide Compatibility
Suitable for 30–118.5 kg/m rails, including major standards:
Chinese: QU70, QU80, P50
European: UIC 54, UIC 60
American: A65, A75, A100
Offers two configurations:
(S) with rubber pad: For enhanced vibration dampening.
(H) without pad: For direct rail-to-support installation .
Durability & Corrosion Resistance
Galvanized finish and high-strength steel resist corrosion in coastal, humid, or chemically aggressive settings.
Installation & Maintenance
Bolt Torque
Tighten Grade 8.8 bolts to 250–300 Nm using a torque wrench to ensure secure fixation.
Adjust rail position within the 17mm range before final tightening.
Assembly Steps
Align the clip with the rail and support structure.
Insert the M20 bolt from above or below (no under-access required).
Secure with a hardened washer and nut, ensuring the rubber block contacts the rail uniformly.
Maintenance
Inspect annually for bolt tightness, rubber pad wear, and corrosion.
Replace worn components to maintain clamping force and vibration control.
Applications
Ports & Terminals: Securing rails for gantry cranes and automated guided vehicles (AGVs).
Mining & Quarries: Heavy-duty ore transport rails in underground tunnels and surface operations.
Heavy Industry: Steel mills, power plants, and manufacturing facilities with high-load rail systems.
Urban Transit: Light rail systems requiring easy installation and adjustment.
