Internal Combustion Forklifts vs. Electric Forklifts: Which is Right for You?

If you’re looking for a forklift for your next project, you’ll likely consider the pros and cons of internal combustion forklifts vs. electric forklifts. IC forklifts run on traditional fuels like propane, diesel or gasoline, while electric forklifts are powered by a rechargeable battery. IC forklifts, or lift trucks, are mainly used in outdoor applications. Electric forklifts, on the other hand, are primarily used in indoor settings like warehouses and distribution centers.

With a wide range of electric and internal combustion forklift options available, how can you determine the best solution to meet your material handling needs? In this post, we look at some of the key features of internal combustion forklifts vs. electric forklifts. We compare both models’ performance, cost effectiveness and environmental impact to help you select the best option for your next project.

Pros and Cons of Electric Forklifts

Electric forklifts are commonly used in indoor settings due to their quiet operation and zero emissions. Here are some of the pros and cons of electric forklifts.

Electric Forklifts: Pros

1. Lower Fueling Costs

Electric forklifts are powered by rechargeable batteries, compared with IC models that run on gasoline, liquid propane or diesel fuel. The average cost of electricity to charge a forklift battery is typically much lower than the cost of fuel. That means it will cost you less to power electric versus internal combustion forklifts. 

2. Zero Emissions

Unlike IC forklifts, electric models don’t produce exhaust fumes. This is especially important when working indoors or in confined spaces, where exhaust fumes can be hazardous to workers. Because electric forklifts use less energy than IC models, they are often preferred by environmentally conscious businesses.

3. Less Maintenance

Electric forklifts feature fewer moving parts compared with IC models. This means electric forklifts require less maintenance than IC options. Electric forklifts don’t require oil changes or complicated engine repairs, saving you time and money while keeping your team working.

4. Quieter Operation

Electric forklifts operate much quieter than diesel or propane models. This benefit is advantageous for workplaces where noise reduction is essential, such as warehouses near residential areas or during night shifts. Quieter operation also enhances employee comfort, reduces noise pollution and improves workplace safety by allowing for better worker communication.

Electric Forklifts: Cons

1. Lower Load Capacity

Typically, electric forklifts are better suited for smaller loads. They generally have a lower weight capacity than IC models, and they may not be able to handle heavy-duty projects. Pay close attention to your project needs and to the weight capacity of the forklift you’re considering before making a final decision.

2. Diminished Performance in the Elements

Electric forklifts usually are built for indoor use. Because the forklift is battery-powered, working in the elements can damage its electric components. If an electric model is used outside, it may need expensive weatherproofing for certain components like drive motors.

3. Battery Maintenance and Charging

Electric forklifts require regular battery maintenance to ensure proper charging. Depending on the type of battery the forklift uses, you may need to adhere to specific charging protocols to avoid battery damage. Some batteries require up to eight hours to charge and eight hours to cool, which can interfere with productivity at your project if not accounted for when scheduling shifts.

Pros and Cons of Internal Combustion Forklifts

Now, let’s look at some of the pros and cons of internal combustion forklifts.

Internal Combustion Forklifts: Pros

1. Higher Load Capacity

IC forklifts generally have a higher load capacity and greater power than electric models. In addition, IC models will not experience a decrease in load capacity as the work shift continues. In electric forklifts, the power and lifting capacity begins to decrease as the battery charge drains.

2. Longer Operating Times Between Refueling

IC forklifts run longer between refueling than most electric forklifts. Electric options need regular battery charging, which can take several hours to complete. Longer operating times between refueling means your team is more productive and experiences less downtime.

3. Easy Refueling

Refueling an IC forklift is a quick and straightforward process. You simply refill the fuel tank like you would on a car or truck. IC forklifts refuel in a matter of minutes, allowing your team to get back to work with little interruption.

Internal Combustion Forklifts: Cons

1. Higher Fueling Costs

IC forklifts run on gasoline, diesel or propane, which can be more expensive than recharging an electric forklift’s battery. Over the long-term, the cost of refueling an IC forklift is typically greater than recharging an electric forklift, even though the process is faster and more efficient.

2. More Maintenance Needs

IC forklifts feature more complex engines than electric models. IC models have more moving parts and fluids that need to be maintained. This means IC engines require more upkeep than electric engines. Herc Rentals IC forklifts undergo meticulous inspections and maintenance between rentals so they can deliver optimal material handling performance every time.

3. Less Environmentally Friendly

IC forklifts produce exhaust fumes that can be hazardous to workers in enclosed spaces. This is why IC forklifts primarily operate outdoors. IC engines also create more waste related to maintenance, like engine oil and transmission fluid, requiring specific disposal processes.  

Which Forklift Is Right for You?

Ultimately, choosing between internal combustion forklifts vs. electric forklifts will depend on the needs of your project and the environment of your jobsite.

If you plan to use the forklift primarily indoors for lighter projects, an electric forklift may be the best choice. However, if you have heavy-duty material handling needs in an outdoor project site with rough terrain, and IC forklift may be more suitable.
