The Safe-Stop Trailer TMA is a development of the popular SS90® TMA, but in an easy to use trailer package. The Safe-Stop Trailer high-speed TMA meets HCHRP 350, Test Level 3 standards and can be used in work zones with posted speeds as high as 100 km/h. In addition to its high-speed protection, the SST® TMA offers exceptional durability. The SST® can withstand nuisance hits up to 10 km/h. Its two-cartridge design is modular to allow replacement of a single cartridge during partial impacts - reducing refurbishment costs. The cartridges are contained in a reusable steel support frame. All of these features reduce the system's overall life cycle cost as compared to other disposable TMAs on the market today. The SST® TMA features hydraulically locking anti-rotational dampeners, preventing the trailer from swinging sideways in the event of an oblique impact. The SST® TMA is ideal for contractors requiring flexible use of their truck fleet.
