Propane fuels 670,000 forklifts in U.S. factories and warehouses, representing the largest segment of the propane internal combustion engine market. Propane forklifts are used to engage, lift, and transfer palletized loads in warehousing, manufacturing, materials handling, and construction applications both indoors and outdoors.


Of the seven classes of electric and internal combustion engine forklifts, propane forklifts primarily comprise three classes: Class 4 (internal combustion engine trucks with solid tires), Class 5 (internal combustion engine trucks  with pneumatic tires) and Class 6 (electric and internal combustion engine tractors with both solid and pneumatic tires). Propane has become a fuel of choice by operators of these forklift classes due to the reduced emissions and operational advantages that propane forklifts offer.

Propane forklifts provide the following benefits:
•    Produce 19 percent fewer emissions than gasoline forklifts and 7 percent fewer emissions than diesel forklifts.
•    Meet 2007 Environmental Protection Agency standards (forklift engines with off-the-shelf electronic engine controls and three-way catalysts).
•    Maintain consistent, 100 percent power throughout operation, with faster ground speeds than electric forklifts.
•    Refuel quickly — it takes less time to fill a propane tank than to switch or charge a battery.
