Diesel forklift trucks are most suitable for outdoor operation, and for long term use. The Diesel engine is the most fuel efficient as it tends to operate longer than the other fuel types.
The engine produces a higher torque compared to gas powered trucks, which improves their performance on gradients and increases the power available for towing or scooping aggregates.
Furthermore, there’s no danger of suddenly losing power as there would with gas or electric powered engines. This is specifically important when using hydraulic attachments such as rotating clamps, forward tipplers and fork spreaders.
Unlike electric models which require overnight charging, diesel forklifts can be used at any time without a break. With a gauge indicating when the fuel tank is nearly empty, there are no sudden stoppages that can occur with gas powered forklifts, and refilling rakes just a few minutes.
