The forklift truck is a working vehicle equipped with wheels and powered by diesel engines, which is used for lifting and moving goods inside logistics warehouses or for loading and unloading goods from the transport vehicles. In its basic version, which can have 3 or 4 wheels depending on use (3 wheels for maneuvering in tight spaces, 4 wheels for heavy use), it is equipped with two parallel metal front arms (the so-called "forks") that allow the gripping and handling of pallets, thus favouring a fast and safe movement of large quantities of goods.
