Trailer-mounted attenuator aids work-zone safety

First publishedin The Global Road Safety Review
2015
Gregory’s TTMA-100 trailer-mounted impact attenuator offers an alternative to bulky truck-mounted attenuators for effective work-zone safety, says the company.

The hitch-mounted TL-3 trailer attenuator with patented tube bursting technology utilises the trailer frame as energy absorber to safely dissipate the energy of the impacting vehicle, eliminating the need for separate energy-absorbing material.

The fully-galvanised attenuator meets all required and optional NCHRP 350 Test Level 3 (TL-3) test criteria and can be used with any support vehicle of 10,000-lb GVW or more; no maximum weight limit.
