Diesel forklifts offer several advantages, such as robust power and torque, making them suitable for heavy lifting and outdoor applications. They typically have a longer lifespan and can operate for extended periods without frequent refueling. However, they tend to be noisier and emit exhaust fumes, which can be problematic in enclosed spaces. Compared to electric forklifts, diesel models have higher fuel costs and maintenance requirements. While LPG forklifts share some advantages of diesel in terms of power, they offer cleaner emissions but still fall short of electric models in terms of environmental impact. Overall, the choice largely depends on the operational environment and specific needs, balancing power with emissions and operational costs.
