GDGL clips, also known as 514 double-hole clips, are heavy-duty fastening components primarily designed to secure steel rails to I-beam girders or concrete support structures. These clips are essential for maintaining track stability in industrial environments like steel plants, mining operations, and container terminals.
Key Specifications and Components
GDGL clips are typically manufactured from Q235B carbon steel, chosen for its high tensile strength and durability. A standard set of GDGL rail clips includes:
One Double-Hole Clip: The main body that provides the clamping force.
One Base Pad: Often a composite rubber pad used to absorb vibration and reduce noise.
Two Wedge-Shaped Pads: These provide a wedge structure to limit lateral displacement of the rail.
Two Sets of Bolts/Nuts: Hexagon or pre-embedded bolts used to fasten the assembly to the support beam.
Core Functions and Performance
Powerful Clamping Force: They generate a clamping force of ≥60kN to prevent longitudinal creep and lateral movement.
Load Distribution: They transmit vertical and horizontal impact forces from moving machinery uniformly to the underlying foundations, preventing stress concentration.
Adjustability: The body of the clip often features elliptical long holes to allow for precise lateral alignment during installation or maintenance.
Fatigue Resistance: High-quality GDGL clips are tested to withstand over 2 million fatigue cycles under heavy loads.
Primary Applications
GDGL fastening systems are widely used in the following scenarios:
Crane Runway Systems: Securing tracks for overhead industrial cranes, gantry cranes, and stacker-reclaimers.
Heavy-Haul Railways: Supporting rails that carry extreme loads, such as those in coal or ore transport lines.
Industrial Sidings: Fixing tracks in logistics parks and ports where frequent start-stop cycles occur.
