HDGY Rail Clips

Features of HDGY Rail Clips

1. Elastic Fixation and Reduced Wear
   • HDGY Rail Clips are designed for elastic fixation of rails to concrete crane beams.
   • They reduce rail head wear, minimize crane beam impact, decrease crane wheel flange wear, and lower noise levels.
2. Enhanced Stability with Elastic Composite Rubber Pad
   • The inclusion of an elastic composite rubber pad between the rail and crane beam increases friction, preventing rail movement.
   • It also eliminates or minimizes uneven gaps along the rail length, improving bolt stress distribution on the clamp plates.
3. Optimal Stress Distribution
   • The rubber pad features a slightly convex cross-section for rational stress distribution.
   • Small rectangular ridges on the pad enhance contact with the rail, increasing elasticity and providing vibration dampening.
4. Durable Design
   • Rectangular grooves on the pad minimize lateral deformation under stress and reduce surface damage from compression.
   • With treated steel reinforcement, the structure is highly durable, maintaining excellent performance even after 2 million fatigue cycles.
5. Secure and Symmetrical Clamp Plates
   • Clamp plates are firmly secured to the crane beam and resistant to loosening or crane beam wear.
   • The symmetrical clamp plates form a wedge-shaped structure in the cross-section, limiting lateral rail displacement.
6. Adjustability for Installation and Maintenance
   • Elliptical slots in the clamp plate allow lateral adjustments.
   • Sloped holes paired with anti-slip blocks prevent clamp movement, simplifying lateral alignment during installation or maintenance.
7. Tolerance for Rail Movement
   • The system accommodates slight rail movements during crane operation, ensuring flexibility without compromising stability.

Installation Steps for HDGY Rail Clips

1. Positioning the Rubber Pad
   • Place the rubber pad with its rectangular ridges and grooves aligned parallel to the rail and underneath it.
   • Ensure the pad is perpendicular to the rail’s centerline and positioned relative to the bolts on both sides.
2. Preparation of the Base Layer
   • Before placing the rubber pad on the concrete base layer, clean the surface thoroughly to prevent debris from reducing performance.
3. Assembling the Clamp Plate
   • Follow this sequence:
     • Insert bolts into the pre-drilled holes in the reinforced concrete crane beam.
     • Place the clamp plate body.
     • Add the anti-slip block (with the small end facing the rail).
     • Add the spring washer and nut.
     • Pre-tighten the assembly.
     • Adjust the clamp plate to press tightly against the rail edge.
     • Finally, fully tighten the bolts.
4. Alignment of the Clamp Plate
   • Ensure the clamp plate’s centerline is perpendicular to the rail’s centerline without skewing.
