Details

The Scorpion 100K Truck Mounted Attenuator is mounted to a shadow vehicle for purposes of protecting the work crew in front of the shadow vehicle and protecting the motorist that might drive into the lane closed off by the shadow vehicle. Shadow vehicles should be trucks in a weight range of 16,000 lbs. to 20,000 lbs. and preferably 20,000 lbs., which is the weight of the truck tested for certification. The attenuator is tested at 100 km an hour for use on trucks needing high speed protection. The cartridge section of the device has a hydraulic system and a scissor lock that engages to lock the cartridge in position. The cartridge is then lowered with an operators switch which releases the lockout and lowers the cartridge.

A steel back-up plate is attached to the rear of the truck and is constructed out of all steel angles, plates, and c-channels welded using mig welding. Two all aluminum tube frames extend from the back-up plate and are welded using mig welding on both sides of the tube and plate interface. The tube frames hold a series of 4 aluminum boxes filled with energy absorbing aluminum honeycomb. Each box is constructed using closed end sealing rivets for joining the sheet metal and the aluminum honeycomb is joined to the aluminum face sheets using oven cured epoxy resin.

• TL-3 device tested at 100 km/hr

• Uses a strut system in addition to the TL-2 cartridge section to achieve a higher speed device

• Energy absorbing cartridges are aluminum honeycomb in environmentally sealed aluminum containers

• Modular design crushes in stages, reducing repair costs

• Curved design provides full width protection to the host truck and protects the "coffin corners" of the truck

• Scorpion's low profile and open tubular design minimize wind resistance and drag, allowing you to drive at freeway speeds safely with no buffing at high speeds

• Lightweight aluminum construction minimizes rust and other corrosive elements

• Durable construction and heavy duty side rails help minimize incidental back-up and turning damage

• Hydraulic pump can tilt unit to 90°

• Extends only 13' from rear of truck when deployed
