Two New Products Improve Safety in Highway Construction Work Zones

An industry leader and global supplier of commercial highway products, Trinity Highway recently added two new products that comply with the Manual for Assessing Safety Hardware (MASH) for testing standards accepted by AASHTO and FHWA. They are the SMT™ and the SS180®M. Both are truck/trailer-mounted attenuators (TMAs) that can be attached to the rear of a stationary or moving shadow support vehicle. The two products are tested to MASH Test Level 3 and are designed to help absorb rear-end impacts at speeds up to 62 mph (100 km/h) when impacted within MASH crash test standards.

SMT is a trailer-mounted attenuator for efficient deployment. Its system is comprised of two lightweight aluminum cartridges contained in a steel support frame. It has LED lighting, replaceable energy-absorbing cartridges, and a potentially reusable steel frame after an impact within MASH crash test standards.

The SS180 M is a truck-mounted attenuator consisting of two lightweight aluminum cartridges contained in a potentially reusable steel support frame. It is designed to help minimize damage from low-speed nuisance hits up to 6 mph.
