The Case for Choosing 3-Phase AC Electric Forklift Trucks Over Vehicles Based on DC Electric, Internal Combustion or Diesel Technologies

In the early 90’s, Jungheinrich was the first company to use static inverters to change the direct current of a forklift truck’s battery into 3-phase AC current, opening the door to the many benefits of AC-power (See Sidebar entitled “Chronology of three-phase AC introduction”). Today, Jungheinrich installs its proprietary AC technology in all its electric truck categories (counterbalanced models, reach trucks, very narrow aisle vehicles and electric pallet trucks, among others – See Fig. 1). It has now been tested and proven in all areas of the material handling industry.
