Devices and systems for improved traffic control signal assembly

摘要

Methods and apparatuses are provided for improved traffic control devices including a continuous central hanger support system that is integral to the traffic control device and provides a central load path. In an embodiment of the invention, the terminal housing and traffic signal housing of the traffic control device can be included in a single unit housing. A single unit housing can also include an integral backplate. Also provided are span wire clamps, tether clamps, and mast arm clamps that can be used to affix the continuous central hanger of the traffic control device to various fixtures such as a single span wire, two span wires, a pole or a mast arm. The continuous central hanger integrated with the single unit housing can provide the traffic control device with improved securement of electrical components and structural stability for survivability during high wind events as compared to conventional traffic signal devices.

主权项

1. A support apparatus for a traffic control device, wherein the traffic control device has a terminal housing and a traffic signal housing positioned below the terminal housing, and a mounting support positioned above and supporting the traffic control device, the support apparatus comprising:
a continuous load path hanger, a majority of the continuous load path hanger in operation is deployed closer to a vertical central axis of the traffic control device than to edges of the traffic control device, the continuous load path hanger extending vertically along at least a portion of the traffic control device; and connection hardware that operably connects the continuous load path hanger to the mounting support and the traffic control device; wherein the continuous load path hanger in operation receives the load of at least most of the gravitational and wind-induced stresses of the traffic control device and transmits those stresses past the terminal housing and to the mounting support.
