Air Technical Industries (ATI), Mentor, Ohio, developed new heavy duty self-propelled platform truck-tug. In addition to carrying heavy loads, it is powerful enough to pull along several trailers or loads simultaneously, saving time by doing it in one trip instead of multiple trips.
The propulsion is battery-powered 24 volt DC, and controls are built-in below the platform, which can open at one end for service access. The travel speed varies from zero-4 mph and is equipped with automatic braking.
