Mitsubishi Forklift Trucks has developed Envir02 engines that work on the line of 3,000- to 7,000-lb. capacity pneumatic tire forklifts. These engines exceed U.S. Environmental Protection Agency 2004 standards for emissions of hydrocarbons, carbon monoxide and nitrogen oxides. A gas cylinder aids in balancing the liquid propane tank while controlling directional movement. An extended powertrain warranty from the manufacturer covers all key components, including engine, fuel system, exhaust, transmission, drive line and drive axel.
