Patent

CA 2316562

A railroad crossing gate mechanism is provided that includes a gate arm adapter which is pivotally mowed to allow a lowered gate arm to rotate away from a generally perpendicular force in a generally horizontal plane. The gate arm mechanism further includes multiple interchangeable spring assemblies that generate a retain force to bring a displaced gate arm back to its normal operating position, and a latch hook assembly for selectively latching the gate arm in its normal position and controlling the rate of return of the gate arm from a displaced position through application of a pivotally leveraged force to a braking surface.
