Rough terrain lift trucks are two axle machines for materials handling on unimproved ground. They either feature a vertical mast – similar to an industrial forklift truck – or a telescopic boom. The latter are often called telescopic handlers or simply telehandlers. Telehandlers can be fitted with a variety of attachments, including pallet forks, bucks and access platforms, which combine with their vertical and horizontal reach capabilities to provide a versatile machine.
