Diesel Forklifts Versus Electric Forklifts
Forklifts can function one of two ways, either by internal combustion (IC) motor or by electric motor. Electric forklifts are best for indoor application and cost less to use. IC machines are suitable for use outdoors and are faster to refuel.
Electric Forklifts
For indoor applications, where the quality of air is a concern, the electric forklift is the best machinery you can use because it produces no exhaust. Electric forklifts are clean and are not noisy. They are 20% to 40% more expensive to purchase compared to IC lifts, but the operating cost of electric models on a per hour basis is a lot less. The disadvantage is that batteries require 16 hours to charge and cool down, so buying an extra set of batteries is suggested. Electric lifts are not limited to indoor application, but when used outdoors they must be utilized carefully.
Diesel Forklifts
Internal Combustion forklifts are for outdoor applications, and their carrying capacity is more than electric forklifts. If your fleet normally runs on one type of fuel, it may be a wise idea to purchase an IC unit that utilizes the same kind of fuel. They could run on gas, propane or diesel. Diesel is the most economical. IC forklifts have the advantage of being cheaper to operate and easy to refuel; then again, their operating cost on a per hour basis is higher. Most IC models cannot be used indoors.
Other Types of Forklifts
Narrow-aisle electric forklifts are recommended for tight spaces within warehouses. They are designed to pick up loads without having to face the lift towards the stacks. Rough terrain diesel forklifts have large tires for running on difficult surfaces.
