Diesel

Diesel forklift trucks run on diesel fuel, and they tend to be the largest type of forklift. The ideal environment for them is outdoors, If you’re considering adding a diesel machine to your fleet, check out the main diesel forklift pros and cons below. 

Pros 

• Unit price: While not as cheap as propane forklifts, the initial cost of a new diesel forklift truck is usually much less than an electric one. When deciding between a diesel vs. electric forklift, you’re better off selecting the former option if you seek cost-effectiveness.
• Fuel price: Diesel fuel tends to be significantly cheaper than propane, saving you more money over time.
• Torque: Diesel engines can produce much greater torque than propane or electric, enabling them to do more substantial work — lifting heavier loads, going up steeper ramps, and accelerating more rapidly.
• Long lifespan: Diesel forklifts tend to last the longest out of the three types, giving you the most time in return for your investment.
• Easy maintenance: Diesel engines typically require less maintenance than propane or electric ones, due to their longevity and durability.
• Higher residual value: Diesel forklifts are generally worth more at the end of their life than propane or electric models.

 Cons 

• Unit price: Though cheaper than electric forklifts, diesel forklift trucks are typically more expensive to buy new than propane ones.
• Maintenance costs: Diesel engines may require less maintenance than their counterparts, but when they do need it, it tends to cost more.
• Environmental impact: Diesel is a fossil fuel, meaning it releases significant amounts of carbon into the atmosphere. While not nearly as bad as many fuels, it’s the least environmentally friendly of the three types used in forklifts.
• Noise: Diesel forklifts are unquestionably the loudest of the three. Fuel combustion occurs at a high volume, which can be inconvenient.

LPG

LPG forklift trucks use propane as their fuel source. Regarding size, they occupy the middle ground between diesel and electric forklifts. The same is true of their ideal environment — they can be comfortably operated both indoors and outdoors. Learning these propane forklift pros and cons can give you more information on this equipment type. Pros 

• Unit price: Propane forklifts are usually less expensive than both diesel and electric forklift trucks when buying new. In the debate of gas forklifts vs. electric, the former wins on sticker price.
• Fuel efficiency: Propane forklifts have the greatest efficiency, as they can run for the longest time on a given amount of fuel. They can usually last for an entire shift on a single tank.
• Refuel time: Propane fuel tanks are easy to switch when depleted, minimizing the amount of time spent on refueling during a shift.
• Torque: Though propane forklift truck torque isn’t as high as diesel, it’s significantly greater than electric.
• Environmental impact: Despite not being as environmentally friendly as electric forklifts, propane trucks release far fewer emissions than diesel ones, making them the more sustainable of the two.

 Cons 

• Overall cost: Though propane forklift trucks have the lowest sticker price, the cost of ownership over time tends to be higher than that of either diesel or electric.
• Visibility: Due to the space taken up by the fuel tank on the back of the machine, propane forklifts have poor rear visibility, making them harder to navigate.
• Lower residual value: Out of the three forklift types, propane tends to have the least residual value at the end of its life.
• Torque: Propane trucks may have better torque than electric ones, but they still have significantly less than diesel.
• Environmental impact: Though propane is more environmentally friendly than diesel, it’s still a fossil fuel, making it inferior to electric concerning sustainability. It also releases high quantities of carbon monoxide.

Electric

Electric forklift trucks run entirely on rechargeable batteries instead of fuel tanks. They tend to be the smallest type of forklift, and their ideal environment for use is indoors. If you’re stuck between an electric vs. LP gas forklift — or a diesel model — these electric forklift pros and cons can help you decide. Pros 

• Fuel price: Because electric forklifts don’t use traditional fuel, they don’t have the refueling costs that diesel and propane do.
• Noise: The absence of fuel combustion leads to much lower noise levels, making electric forklift trucks easily the quietest of the three types.
• Maneuverability: Without the need for fuel storage, electric forklifts are smaller and more compact than their counterparts. They are therefore much easier to turn and maneuver, particularly through small, enclosed spaces.
• Environmental impact: Electric forklift trucks don’t burn any fossil fuels, which means they don’t release any carbon emissions. This arrangement makes them very environmentally friendly, more so than diesel or propane. Choosing between an electric vs. propane forklift is easy if you value sustainable machines.
• Maintenance costs: Since electric engines have less complex mechanics than diesel or propane ones, they’re less expensive to maintain and repair.

 Cons 

• Unit price: They may save on fuel costs down the road, but electric forklifts usually have the highest initial price out of the three types.
• Torque: Unfortunately, the cost of sacrificing fuel results in significantly lower torque. Electric forklift trucks can occasionally have a hard time reaching high speeds or making it up ramps.
• Quality decline: Diesel and propane forklifts can run at more or less the same level of efficiency until all their fuel is gone. Electric forklifts, however, decline in speed and power as their battery drains, making them less useful later in the day. Ensure you know how much electricity your forklift uses before making your final choice.
• Refuel time: Electric batteries take a long time to recharge. If an electric forklift depletes its battery two-thirds of the way through a shift, it may be out of commission for the rest of the day.
