The frame helps to contain any debris.
Even in the most severe of incidents, the frame prevents the bullet vehicle
from smashing all the way through, preventing damage to the truck.
The rigid support/lifting frame is designed to protect the rear of the truck
from damage.
Research showed that during an impact, many competitors products deformed in
such a manner.
During development for safety testing, this crash cushion was vibration tested continuously for a period of one month, with no signs of wear or failure (see image).
