The Iron Man of Firefighting Imagine climbing upwards of a grueling 50 flights of stairs while wearing 30 pounds of gear. That’s the reality for many high-rise firefighters. A little help would be nice, right?! That’s where the AFA Powered Exoskeleton comes in. Strapped over the firefighter’s gear, the device provides supplemental muscle to aid performance in walking, running and carrying up to 200 lbs.. Enough to carry equipment or even injured victims in time-crucial emergency situations.
