Diesel Forklifts Vs. Electric Forklifts
Forklifts could function one of two ways, either by electric motor or by internal combustion (IC) motor. Electric forklifts are best for indoor application and cost less to utilize. IC machinery are best for outdoor application and are faster to refuel.
Electric Forklifts
Electric lifts produce no exhaust, that makes them the equipment of choice for indoor use where air quality is a concern. Electric forklifts are not noisy and clean. They are 20 - 40 percent more expensive to purchase than IC lifts, but the operating cost of electric models on a per hour basis is less. The downside is that batteries need 16 hours to charge and cool down, so the purchase of an extra set of batteries is suggested. Electric lifts are not limited for use indoors, but when used outdoors they should be utilized carefully.
Diesel Forklifts
Internal Combustion forklifts have a higher carrying capacity than electric forklifts and are usually utilized 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 can function on propane, diesel or gas. Diesel is the least expensive. IC forklifts have the advantage of being cheaper to operate and easy to refuel; nevertheless, their per-hour cost to operate is higher. Most IC models cannot be used indoors.
Other Forklifts
Narrow-aisle electric forklifts are suitable 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.
