Fork trucks are versatile pieces of material handling equipment, crucial for various industries. These trucks are primarily categorized by the type of power they use, such as electric, diesel, or gas, and by their functionality, like counterbalanced, narrow-aisle, and reach trucks. The main function of a fork truck is to lift, move, and stack heavy materials safely and efficiently. Technological features vary but often include advanced AC motor technology for smoother operation, programmable controllers for precision lifting, and various safety features like operator presence sensors. Applications range from warehouses and distribution centers to manufacturing plants and construction sites, where heavy loads need to be transported with ease.
