Industrial trucks are vehicles used for the internal transport of goods. They can be trackless, track-bound or track-guided and have equipment for lifting and stacking loads. Mainly, these vehicles are used in horizontal goods transport in warehouses and production halls of companies. Probably the best-known and most important industrial truck in industry and commerce is the forklift truck, which belongs to the group of trackless material handling vehicles. The second group includes, for example, trolleys, which, however, are used less frequently in everyday warehouse operations. Instead, track-bound systems, which include driverless transport systems, are more common. Industrial trucks have a high flexibility and are characterized by good maneuverability. At the same time, they require a high level of operating effort, which in some cases is offset by a considerable amount of maintenance. Industrial trucks are moved along paths between stored goods. They are moved either by manual muscle power or automated by electric, diesel or gas engines. Smaller industrial trucks such as pallet trucks do not require a forklift license, whereas forklifts do.
