  • Span bolster
    Patent number: 12565247
    Abstract: A method for manufacturing a multiple axle railcar utilizing a non-stressed span bolster is disclosed. The span bolster supports the load of the railcar using camber to efficiently distribute the load from the railcar among the truck assemblies and axles. The manufacturing method discloses the fabrication and layout of a span bolster where non-stressed camber is incorporated into the structural elements of the span bolster. The camber is produced geometrically by parallelogram shaped plates supporting the weight of the railcar. The amount of camber may be modified for different load ratings. The railcar and span bolster are constructed of alloy steel to minimize railcar tare weight and maximize load capacity.
