Joint bars (fishplates) with 4 holes for 60E1 (UIC 60) rail are essential heavy-duty connectors designed for standard track applications, typically weighing between 17.47 kg and 18.1 kg per piece. These components connect the ends of two 60.21 kg/m rails to ensure track stability and smooth load transfer. While 6-hole variants offer 50% more clamping force for high-stress main lines, 4-hole bars are widely used in standard maintenance, industrial branches, and crane tracks where ease of installation is a priority.
Manufactured according to international standards such as UIC 864-4 and EN 13674-1, these bars are precision-engineered to match the 60E1 rail profile.
Standard Lengths: Commonly available in 600 mm or 630 mm.
Hole Configuration: Features 4 round or oval holes, typically with diameters of ø25 mm, ø26 mm, or ø28 mm.
Material Grades: Typically forged from high-carbon steel like 55#, 45#, or Q235 to withstand extreme dynamic stresses.
Weight Variance:
600 mm / ø28 holes: ~17.47 kg.
630 mm / ø26 holes: ~18.07 kg.
630 mm / ø25 holes: ~18.10 kg.
Precision Alignment: The top and bottom edges are tapered to wedge securely between the rail head and base when bolted, maintaining critical vertical and horizontal alignment.
Durability: High-carbon steel construction provides the necessary fatigue and impact resistance for axle loads exceeding 30 tons.
Versatility: Suitable for standard freight lines, passenger transit, and heavy-duty gantry crane tracks.
Protective Treatments: Available with surface finishes like black oil, black oxide, or hot-dip galvanizing to prevent corrosion in harsh environmental conditions.
