Fork lift truck or fork truck is an industrial truck which is powered to lift and transport materials in warehouses, shipping depots, manufacturing and many others. After the World War II, the use and development of forklift truck has increased globally. A forklift can only load a specified maximum weight and cannot exceed the specifications, which are also mentioned on a nameplate provided by the manufacture. Overweight of loads or speed may cause disastrous tip-over accidents. These trucks are addressed in specific standards for the construction, general industry, marine terminals and longshoring, For instance, standards provided by the Occupational Safety and Health Administration (OSHA), an agency of the United States Department of Labour, compliance information that applied to specific activities, involving loading and unloading, working with hazardous materials and vehicle maintenance.
