If you require a forklift for outdoor work, capable of being used 24/7 with a hardy nature and fuel efficiency, a diesel powered forklift could be the solution you’re looking for.
Available from 1.6 ton up to 9 ton, diesel forklifts have a lot more power behind them, allowing these machines to work better on gradients, in poor conditions and also make them more suited for towing/pushing duties.
Although far better suited to outdoor use due to fumes, diesel powered forklifts can be used indoors (though it’s not recommended and if they are used, it’s better that its done irregularly).
Due to their large size, tight maneuverability is not their strong suit, and the noise and fumes they emit could put some users off. However if you’re looking for strength, reliability, reasonable purchase rates and sensible maintenance costs, these could be the forklifts for you.
