Cable dampening system and traffic control assembly comprising same
A traffic control assembly comprising a length of flexible cable as a cable dampener. The cable may be formed of wire rope, which comprises a bundle of twisted wire strands, with a fitting at each end. The cable section has the ability to resist torsional movement and the ability to bend to a limited extent along its vertical axis in response to wind forces and to return to its resting or straight configuration like a spring as the wind subsides. This provides a dampening function between the components of the traffic control assembly to absorb impacts imposed by winds or moving objects so as to reduce the likelihood that the connection will break and disconnect or dislocate the signal or other traffic control device.
1. A flexible hanger assembly for a traffic control assembly, wherein the traffic control assembly comprises a traffic control device attached to the bottom of a disconnect hanger box, wherein the traffic control assembly is supportable from a span wire and messenger wire, and wherein the flexible hanger assembly comprises:
an upper rigid hanger member having first and second ends, the first end connectable to the span wire;
a lower rigid hanger member having first and second ends, the second end connectable to the disconnect hanger box;
wherein the upper and lower rigid hanger members are conventional hanger extension bars;
a flexible hanger connector comprising:
a length of flexible cable having first and second ends, wherein the length of flexible cable comprises wire rope;
a first end fitting having first and second ends, the first end connectable to the first end of the flexible cable and the second end connectable to the second end of the upper rigid hanger member; and
a second end fitting having first and second ends, the first end connectable to the second end of the flexible cable and the second end connectable to the first end of the lower rigid hanger member;
wherein each of the first and second end fittings has a front face and a rear face, and wherein each front face has a pair of spaced apart parallel ribs configured to mate with the conventional hanger extension bars.
2. The flexible hanger assembly of claim 1 wherein each rear face defines a bolt channel.
