Diesel fuelled trucks are most suitable for outdoor use where the fumes they produce can easily escape without concentrating in an enclosed space and causing environmental or safety issues.
Diesel forklifts have a higher torque compared with a gas powered trucks, which improves their performance on gradients and increases the power available for towing or scooping aggregates.
Furthermore, with diesel engines there is no danger of suddenly losing power, as there can be with gas or electric powered engines, which is especially important when hydraulic attachments are in use, including 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.
