Fortis Exoskeleton

FORITS Exoskeleton System

Whether grinding barnacles off a ship’s hull, welding a long section of beam or drilling hundreds of holes in preparation for riveting, repetitive work using heavy hand tools can be physically exhausting. With only a limited time to work on the task before requiring a rest, tool operators run the risk of extreme muscle fatigue. Lockheed Martin’s FORTIS® exoskeleton allows operators to effortlessly support heavy tools, enhancing their strength and endurance.

FORTIS™ exoskeleton transfers loads through the exoskeleton to the ground in standing or kneeling positions and allows operators to use heavy tools as if they were weightless. An advanced ergonomic design moves naturally with the body and adapts to different body types and heights. Using the FORTIS tool arm, operators can effortlessly hold heavy hand tools, increasing productivity by reducing muscle fatigue.

Recently, the National Center for Manufacturing Sciences concluded that the FORTIS exoskeleton could mitigate nearly all injuries from industrial power tools by making them effectively weightless during operation.




The FORTIS tool arm design is a lightweight extension to Lockheed Martin’s FORTIS exoskeleton. Targeted particularly for hand-held industrial tool use, the arm has a lightweight, folded aluminum construction that eliminates pinch points. User-selected stainless steel locking mechanisms also prevent unwanted movement for greater safety.

By supporting the weight of heavy tools that may weigh as much as 36 pounds, the arm significantly reduces the user’s metabolic burn rate that leads to fatigue and other health issues. Operators using the arm can focus on operating their tools without the strain of having to support them which effectively renders the tool weightless and extends their work periods by a factor of up to 27. Now, one person can safely do the work of many.

The tool arm uses an adjustable spring tension system instead of hydraulics or motors, which reduces emissions to zero and can be used with the FORTIS exoskeleton system or station-mounted and operated independently of the system via the FORTIS tool arm bracket.
