Electric vs. Combustion: How to Choose the Right Forklift

Written by Canadian Forklift | Dec 8, 2023 4:24:24 PM

Forklifts come in many shapes and sizes, which means it can be tough to figure out which one will work best for your needs. Of course, you can probably figure out that a massive forklift capable of picking up and moving pallets that weigh over 7,000 pounds doesn’t belong in your moderately-sized supply yard, but the question remains: Electric or combustion engine? Let’s go over the pros and cons of each.

Combustion forklifts: Yay or nay?

A combustion engine is a traditional vehicle engine that burns fuel to create tiny explosions that push a piston (or series of pistons), which in turn rotates a crankshaft. This moves a system of gears that ultimately drives the vehicle’s wheels and moves other parts of the machine, including a set of hydraulic pistons that lift and lower the fork.

Forklifts with combustion engines normally use gasoline, diesel fuel, liquified petroleum gas (LPG) or compressed natural gas (CNG) in their engines. LPG is a type of natural gas, while CNG is a compressed natural gas that is commonly used in ovens and furnaces. Diesel is a denser type of gas with a higher price point but an estimated 20 percent more fuel efficiency than regular gasoline.

Combustion engine machinery is traditional, and there are plenty of reasons to choose a fuel-burning forklift for your business. Of course, there are some drawbacks to keep in mind as well.

Pros of internal combustion forklifts:

  • Quick to refuel
  • More often designed for outdoor work
  • Consistent power levels
  • Higher speeds when travelling

Cons of combustion-engine forklifts:

  • Not ideal for indoor spaces because of the carbon monoxide in the fuel exhaust
  • Can be noisy
  • Require fuel storage
  • LPG engines can be damaged if you run completely out of fuel
  • Negative environmental impact

Electric-engine forklifts: Why and why not?

Electric vehicles run on battery packs, which are normally charged via electrical sockets. They can also recharge at specialised charging ports like those designed for road vehicles, so long as the proper voltage is available. The electricity used to power a vehicle battery can come from a variety of sources, including hydroelectric plants and coal-burning plants.

Electric motors work by converting primary electricity into movement, just as a combustion engine converts the force from burning fuel into movement. In this case, the electric current from the battery is run through a magnetic field, which creates a force that spins a wire coil and produces the movement required for anything from a blender to a forklift truck.

The advantages of using an electric forklift over a fuel-burning one are mostly quite obvious, but there are some benefits and drawbacks to using this type of work vehicle that you may not have considered before.

Pros of electric-engine forklifts:

  • No fumes from exhaust
  • No noise
  • Little effect on ambient temperature, so won’t raise the temperature of your cold storage space
  • No fuel cost
  • No fuel storage necessary
  • Running a vehicle on electricity is cheaper than running one on fuel
  • Fewer moving parts that need to be maintained and replaced over time

Cons of electric-engine forklifts:

According to the World Industrial Vehicle Statistics Association, 2.34 million forklifts were purchased in 2021, and 1.61 of those were electric. The trend is clearly moving towards the electric option, particularly indoors, where it’s necessary to maintain clean air for staff and other people entering the area.

One of the main concerns when operating an electric forklift is the battery power. Once your battery has drained, it will take several hours to recharge—and during that time, your machine is useless. However, you’ll find that universal battery packs work in many forklifts so that you can simply insert a pre-charged battery into the machine while the drained battery charges.

Why go electric?

Moving to electric power in place of fuel-burning engines in your forklifts and other equipment means no emissions and a much lower negative environmental impact. If you live in a region where electric power is supplied by fuel-burning power plants, then this can seem like a fallacy; however, it’s important to remember that this isn’t the case everywhere!

In fact, 60 percent of Canada’s electricity generation comes from hydropower, 5 percent from wind and a fraction of a percent comes from wind. The infrastructure is growing throughout Canada to support more electrical vehicles, and to provide more energy to those vehicles, homes and commercial properties through environmentally sustainably methods. One day, that electric car charging port that seems silly in a fossil-fuel-heavy region won’t need to convert fossil fuel to electricity.

Other considerations in choosing a forklift

It’s important to think about how a forklift will be used while making a decision about which model is the best for your needs. Forklifts, like other equipment, can underperform or suffer damage if used improperly, so for the sake of longevity and saving money on maintenance and repair costs, follow your machine’s instructions!

Take care not to use your forklift in the wrong environment. There are specially designed electric forklifts that operate better than other models in cold warehouses, as they are better protected against the cold and condensation. Other models, both electric and fuel-powered, are better designed for heavy lifting outdoors in the dirt, mud, sand and weather. You’ll also need to think about the tires on your work vehicle—will they damage the floor of your warehouse, or be unable to grip slippery mud in the yard?

There are two basic types of forklifts available: The electric stacker forklift and the construction forklift. Basically, stacker forklifts are designed to pick up and transport palettes over very short distances indoors, while construction forklifts are designed to handle very heavy palette loads and transport them over longer distances.

Checklist for choosing a forklift

To help you make a decision about which forklift you need, we’ve compiled all the information you need to keep in mind. Read through the following checklist and think carefully about each factor—from load weight to the workspace—while shopping for forklifts. Once you’ve purchased your work vehicle (or several) you’ll need to have easy access to fuel, a charging station, off-hours parking and somebody who can perform maintenance and repairs.

  1. Lifting Requirements

    • Lift Height: Determine the required elevation for your loads. If you're dealing with trailers, consider the forklift's lowered mast height.
    • Capacity: Identify the maximum weight you need to lift. Ensure your forklift can handle your heaviest loads, accounting for attachments that may reduce capacity. Common capacity ranges include:
      • Less than 2,000 lbs
      • 2,000 – 6,000 lbs
      • 6,000 – 7,000 lbs
      • 7,000 – 12,000 lbs
      • 12,000 – 17,500 lbs
      • 17,500+ lbs
    • Load Type: Forklift capacities are based on a standard pallet size with a 24-inch load center. If you work with non-standard loads like long, wide, or irregularly shaped items, it will affect capacity. In such cases, consider specialised forklifts like 4-direction forklifts. Consult a material handling expert to determine the right capacity for your specific needs.
  2. Space Considerations

    • Aisle and Doorway Width: Your choice of forklift should accommodate your workspace. Three-wheel and stand-up rider forklifts are suitable for narrow aisles (less than 10 ft or 10-12 feet). In some situations, narrow aisle order pickers or reach trucks might be more appropriate. Measure the narrowest spaces your equipment will navigate before purchasing. Standard forklifts are designed for areas 12 feet or wider. Reach trucks can work in a 9-foot aisle, while models designed for aisles can manage a 7-foot or narrower aisle.
  3. Environment and Terrain

    • Indoor or Outdoor Use: The operating environment influences your choice of fuel type and tire selection. Consider whether the forklift will be used indoors, outdoors, or both.
    • Concrete or Rough Terrain: Select appropriate tires based on your work surface. Cushion tires are suitable for indoor settings like warehouses and loading docks with concrete floors. Pneumatic tires are best for outdoor use, such as on asphalt, dirt, or gravel. In some cases, you can combine both types for versatility.
  4. Fuel Type

    • Electric or Internal Combustion: Decide between electric forklifts powered by batteries and IC forklifts with traditional engines running on various fuels like CNG, diesel, gas or liquid propane. Consider emission requirements, particularly for handling food, where electric forklifts are often necessary. Many applications previously reliant on IC forklifts are discovering that electric conversions save time and money while being environmentally conscious.
  5. Usage Patterns

    • Operational Hours: Determine how many hours per day and days per week you will use the forklift. For busy multi-shift operations, collaborating with material handling experts is advisable to analyse your application thoroughly and identify the most suitable fuel and equipment solutions.
