Scorpion II TL-3 Towable Attenuator Trailer

The Scorpion II Towable Attenuator (TA) is a mobile crash cushion designed with a attenuator tongue and axle/wheel that connects directly to the support vehicle’s pintle hook connection and from a lunette ring on the attenuator. The TA can be used on support vehicles with a minimum actual/curb weight of 12,000 lbs with no upper weight limit (infinite weight). The TA has overall dimensions of 17.8 ft (5.4 m) × 8 ft (2.4 m) × 4.3 ft (1.3 m) with ground clearance of 12.0 in ± 1.0 in (305 mm ± 25 mm). The TA consists of three main components: the attenuator tongue, front Strut, and rear Cartridge. The attenuator tongue is positioned nearest to the support vehicle, the Strut is bolted to the tongue and Cartridge. The Cartridge is the rear most component, furthest away from the support vehicle. The attenuator tongue acts as a standard single point connection under normal towing conditions and is designed with an integral Telescoping Anti-Rotation System (TARS) that is activated when the TA is impacted. The forward sliding action occurs during an impact, upon completion of the full telescoping action the outboard anti-rotation supports come into contact with support vehicle frame plate which in turn prevents angular rotation about the rear of the host vehicle. The Strut consists of four outboard convex aluminum tubes forming an aluminum structural weldment. The aluminum structural weldments bolt directly to the TARS tongue and the rear Cartridge. The structural assembly encompasses the aluminum crush Module D. The Cartridge consists of four outboard convex aluminum tubes forming an aluminum structural weldment. The aluminum structural weldments bolt directly the Struts steel angles and rear diaphragm. The TA uses a Cartridge Diaphragm with an axle/wheel attachment for towing the TA. The structural assembly encompasses the two-aluminum crush Module C’s. Attached to the rear most end of the Cartridge is the single crush Module A.
