Pole-Safe® Omni-Directional Breakaway Supports for Poles

Transpo's "Double Neck" Pole-Safe® breakaway support system is designed for poles located within roadside clear zones and other locations vulnerable to vehicular impacts. The primary component of the system is a high-strength coupling, designed to break away quickly and cleanly upon impact, thus saving lives and reducing property damage. Pole-Safe® couplings are omni-directional, meaning the system breaks away with consistent, predictable behavior, regardless of the vehicle's angle of impact.

Vehicle crash-tested in accordance with NCHRP Report 350, Pole-Safe® is approved for use on all FHWA funded projects. In addition to superior safety performance, Pole-Safe® provides high structural load-carrying capacity. Extensive finite element analysis and simulated wind-load testing has been used to optimize the system for maximum loading conditions.

Pole-Safe® is designed for use with the maximum allowable pole mass as specified by AASHTO. Pole-Safe® can be used on a large range of light pole sizes and configurations for increased safety and efficiency. The high-strength coupling design offers exceptional resistance to forces created by wind and dead loads. Independent fatigue testing has demonstrated that Pole-Safe® couplings are capable of withstanding more than two million loading cycles with no reduction in structural capacity.

Pole-Safe® crash tests were conducted using a 55 foot high, 930 pound pole. Unique physical properties and performance gives designers the greatest flexibility in sizing poles for specific lighting requirements. Pole-Safe® couplings and hardware are hot-dip galvanized in accordance with ASTM A153 to provide corrosion-protection.

No special tools or equipment are required to properly install and maintain Pole-Safe®. All components are easily secured using the American Institute of Steel Construction (AISC) turn-of-nut tightening method, eliminating any precise torque levels on bolts. Low initial cost coupled with high structural capacity and zero maintenance makes Pole-Safe® the most cost-effective solution for all breakaway applications.
