Abstract
Pivot mounts for enabling pivotal attachment of support struts of a fifth wheel hitch assembly to the deck of a raiway car are provided with a fabricated inverted U shaped torque box or beam fixed transversely between upright pivot mount plates of the center sill mounted hitch on the railway car for structural strength and rigidity. Due to the torque box the mount is sufficiently rigid to preclude the need to attach the pivot mount to the inside of the box sill of a railway car.
