Determining the best-suited forklift fuel type for your application is an important factor in running an efficient and cost-effective operation. We’ll describe 3 fuel types- Diesel, LPG, and Electric- along with the appropriate application for each fuel type and their advantages and disadvantages. With this information, you will be able to determine which fuel type would be most suitable for your workplace and whether your current fuel type is appropriate.
Diesel forklifts are most commonly used for heavy lifting, industrial or outdoor applications. The lifting capacity for a diesel forklift ranges from 4,000 lb. to 55,000 lb. Wet or damp environments do not adversely affect the performance of a diesel truck making it a great option for outdoor applications.
Lower running costs, when compared to gas, fueled forklifts
More torque when compared to electric counterparts
Longer lifespan when compared to propane counterparts
Quick refueling – when gas level is low you can simply refuel without wasting time charging a battery
Higher purchase price compared to other fuel types
Create a lot of loud noise
Requires an EPA standard fuel reserve storage room
More maintenance required than electric counterpart
Can only be operated in open spaces or well-ventilated area
Electric forklifts are battery operated and most commonly used for indoor or cold storage applications. These forklifts are safe to use in closed food processing environments because there are no fumes emitted. Electric forklifts should never be used outdoors. Exposure to rain or snow can cause a short circuit.
Most environmentally friendly fuel type
Best suited for indoor and small areas
Longer life span compared to other forklift types
Cheaper consumption when it comes to hourly work compared to gas/diesel
Lower noise level
Low center of gravity; more stable at greater lift heights
Less maintenance because it is more mechanically simplistic (no transmission, torque converter etc.)
Not appropriate for outdoor use especially in wet weather
Extra batteries are needed if the lift is used for extended periods
Charging the battery takes 8 hours plus additional cool down time
Swapping batteries takes 10-45 minutes
Required to have an onsite charging station that is well ventilated, dry and temperature controlled
Liquefied Petroleum Gas (LPG)
LPG forklifts offer the versatility to be used in various environments. This is the perfect option for a workplace that requires both indoor and outdoor applications. Emissions from LPG forklifts are much lower than their diesel counterparts making it safe to use indoors. No concern for short circuits allow this lift to be used outdoor in wet climates.
Low carbon emissions – burns cleaner than diesel with no soot and very few Sulphur emissions
Better travel speeds, rates of acceleration and lift speeds than electric and diesel counterparts due to their power to weight ratios and responsive engines
Parts are readily available
Non-corrosive, nontoxic and free of any additives, high octane rating
Required on-site storage of propane which can be dangerous if not stored properly
More maintenance required than electric counterpart due more complicated engine
Less power than diesel/petrol (90%)
