The Scorpion II METRO Truck Mounted Attenuator from TrafFix Devices

The Scorpion II METRO is the only TL-2 Plus (50 mph / 80 kph) TMA that is MASH Tested, Passed and Eligible.

The Scorpion II METRO is the ideal TMA for cities, counties, and urban districts with posted speeds of 50 mph (80 kph) or less.

The Scorpion II Metro is the shortest TL-2 Plus MASH TMA on the market with a length of only 8 ft (2.44 m), and a vertical storage height of less than 11.2 ft (3.4m), making it ideal for urban areas. The Scorpion II Metro provides full width impact protection by redirecting the impacting vehicle away from the "coffin corner" with its patented curved aluminum tube frames, and energy absorbing modules. The curved aluminum tubes provide protection against nuisance impacts while providing re-directional capabilities along the entire length of the TMA. Each energy absorbing module is made powder coated aluminum boxes with an aluminum honeycomb core for maximum durability and longevity.

The Scorpion II Metro is MASH Tested, Passed and Eligible at "infinite weight" allowing attachment to host vehicles with curb weights of only 7,500 lbs (3,402 kg), such as a Ford F-550.

Like the rest of the Scorpion line of impact attenuators, the Scorpion II Metro has a modular design that crushes in progressive stages, slowing the vehicle to a stop, and allowing easy replacement of damaged parts. This keeps your repair costs down, and helps to reduce waste entering our landfills.

The Truck Mounted Attenuator (TMA) is a mobile crash cushion attached to the rear of a support vehicle’s frame. The TMA may be used on moving shadow trucks, stationary block vehicles, or advanced warning vehicles upstream of a moving or stationary operation. The Metro TMA shall be tested, passed and eligible to MASH TL-2 Plus (50 mph / 80 kph). The TMA can be used on support vehicles with a minimum actual/curb weight of 7,500 lbs (3,402 kg) with no upper weight limit (infinite weight). Lighting consists of LED brake, directional, signal, and running lights for enhancement of advanced warning to drivers. The Metro TMA has an overall dimension of 8 ft (2.4 m) × 8.0 ft (2.4 m) × 2.0 ft (0.6 m) and has a ground clearance of 12 in ± 1 in (305 mm ± 25.4 mm) when deployed in the horizontal operating position. The Metro TMA consists of two (2) main components: Cartridge and backup/diaphragm frames. The Cartridge section is the energy attenuation component. The aluminum structural weldments bolt to a structural steel diaphragm/backup frame. The Metro can be used with all existing Scorpion mounting systems (Standard and Fast-Trak Mounts). The Metro TMA can be vertically lifted in a single 90° fold position to the support vehicles bed with a stored height of less than 10 ft (3.0 m) with the low pivot mounting option or 11.2 ft (3.4 m) with the high pivot option. An optional hydraulic powered vertical lift can be utilized with the Metro TMA to deploy a display panel when the Metro TMA is lowered into the use position. The vertical lift is powered by the same onboard hydraulic system that raises the TMA into the stored and/or use position. The vertical lift is sequenced to raise and lower a panel for displaying advanced messages, directional indicators, or other notifications.
