Advantages

• High performance: Diesel engines typically provide higher power and torque, allowing for efficient handling of heavy loads.
• Long service life: Diesel forklifts can run for longer periods of time without interruptions compared to electric forklifts, making them ideal for continuous operation.
• Durability: They are able to work in a variety of conditions, including outdoors and uneven surface conditions.
• Cost of operation: Currently, diesel fuel can be cheaper on the market compared to batteries for electric forklifts.

Disadvantages

• Emissions: Diesel engines produce harmful emissions, which can be a problem in enclosed spaces or in areas with strict environmental regulations.
• Noise: Using a diesel forklift can result in increased noise levels, which can be a disadvantage in quiet areas.
• Maintenance: Diesel engines require regular maintenance and can have higher maintenance costs than electric models.
• Weight: Diesel forklifts are generally heavier, which can affect their manoeuvrability in narrow aisles.

The choice of a 3.5 tonne diesel forklift truck depends on the specifics of your work. If you need a powerful, robust forklift for outdoor use or in difficult conditions, a diesel option may be ideal. However, if you work indoors and are concerned about emissions and noise, you may want to consider electric alternatives.
