The rear door of the armored vehicle weighs 500 pounds and is opened manually. It was designed for flat ground, which makes opening it difficult on uneven terrain or in a rollover situation.
The new rear door system, developed by engineers from the Naval Surface Warfare Center using commercial off-the shelf hardware, is electric. It is self-powered and can be activated from two locations within the vehicle and from a switch outside the vehicle.
"If all else fails, we have a manual way to crank out the pump's hydraulic cylinder," said Buffalo Systems Deputy Project Engineer Steven (Tate) Carow. "A Marine can pull out a handle, which fits into a slot in the integrated hydraulic cylinder and he or she can then simply use this to jack the door open."
