Electric Forklift versus Diesel Forklift
A forklift can function either by internal combustion (IC) motor or by an electric motor. Electric forklifts are suitable for use indoors and cost less to utilize. IC machines are best for use outdoors and are quicker to refuel.
Electric Forklifts
For indoor applications, where the quality of air is a concern, the electric forklift is the suitable machine you could use as it produces no exhaust. Electric forklifts are clean and are not noisy. They are 20% to 40% more expensive to purchase than IC lifts, but the per-hour operating cost of electric models is a lot lower. The disadvantage is that batteries require 16 hours to charge and cool down, so purchasing an extra set of batteries is recommended. Electric lifts are not limited to indoor use, but when used outdoors they must be used carefully.
Diesel Forklifts
Internal Combustion forklifts are for outdoor use, and their carrying capacity is higher than electric forklifts. If your fleet usually runs on one type of fuel, it might be a wise choice to buy an IC unit which utilizes the same fuel. They can run 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; nonetheless, their per-hour cost to operate is higher. Nearly all IC models cannot be used indoors.
Other Forklifts
Inside warehouses where there are limited spaces, the narrow aisle electric forklift is most suitable. They are constructed to pick up loads without having to face the lift towards the stacks. Rough terrain diesel forklifts have huge tires for running on hard surfaces.
