Propane models can operate in inclement weather and are versatile enough to handle rugged, unpaved outdoor terrains and steep grades. Propane forklifts run at peak performance from the beginning of the shift to the end.

Electric forklifts can only operate on paved surfaces and cannot handle steep inclines, because of the weight of the batteries, which ranges from 2,400-3,500 lbs. They must be stored indoors and are limited to indoor applications.
