Electric Forklift versus Diesel Forklift
A forklift can function either by internal combustion (IC) motor or by an electric motor. Electric forklifts are best for use indoors and cost much less to utilize. IC machinery are best for outdoor use and are faster to refuel.
Electric Forklifts
Electric lifts produce no exhaust, which makes them the machinery of choice for indoor applications where the quality of air is a concern. Electric forklifts are clean and are not noisy. They are 20 - 40 percent more expensive to buy than IC lifts, but the operating cost of electric models on a per hour basis is less. The downside is that batteries require 16 hours to charge and cool down, so purchasing an extra set of batteries is suggested. Electric lifts are not limited for use indoors, but when used outdoors they must be used cautiously.
Diesel Forklifts
Internal Combustion forklifts have a higher carrying capacity compared to electric forklifts and are generally used for outdoor applications. If your fleet normally operates on one kind of fuel, it might be a good choice to purchase an IC unit which uses the same fuel. They could function on diesel, gas or propane. Diesel is the most economical. IC forklifts have the advantage of being easy to refuel and less expensive to operate; however, their operating cost on a per hour basis is higher. Most IC models cannot be utilized indoors.
Other Kinds of Forklifts
Narrow-aisle electric forklifts are recommended for tight spaces within warehouses. They are designed to pick up loads without having to position the lift facing the stacks. Rough terrain diesel forklifts have huge tires for running on difficult surfaces.
