The American Society of Mechanical Engineers (ASME) defines a forklift, also called a powered industrial truck (PIT), as a vehicle used to tier, stack, pull, push, carry, or lift materials. Other names are lift truck, pallet truck, rider truck, lifttruck or forktruck. Before going out shopping for forklifts for sale in Dallas and in Fort Worth, TX, it is a good idea to make sure you know all the different classes of forklift to make sure you get the right one for your uses.
The vector forces that influence a lift truck make it inherently unstable. Each year, almost 100 individuals are killed in accidents involving forktrucks, while more than 30,000 see the inside of an emergency room before they go home from work. Fatalities and serious injuries mostly arise as a result of the forklift tipping over and crushing the rider, or from a collision involving a pedestrian and a lift truck. Studies have shown that most serious forklift accidents in which someone is killed or maimed would have been prevented by proper training. In 1999, the Occupational Safety and Health Administration (OSHA) began levying fines on companies that employed people who did not have the necessary training and certification.
Fork trucks are classified according to whether they are powered by an internal combustion engine or by a battery. Non-electric powered trucks may use gasoline, diesel or liquefied petroleum gas (LPG). Powered industrial trucks are further classified according to the type of tire they have, whether solid or pneumatic. Each one is particularly suited to a specific environment.
Class I forktrucks are powered by electricity and the operator sits on the vehicle. As they do not produce noxious fumes as do internal combustion engines, Class I trucks are used where ventilation cannot support the use of gas-powered vehicles. These trucks may use either solid or pneumatic tires.
Class II PITs, electric motor narrow aisle trucks, are designed for high-density, narrow-aisled warehouses or shop floors. They are used when air quality and conservation of space are important. They have special features that enable them to function optimally in conditions where the aisles are narrow.
Class III trucks are manipulated by hand as the operator walks alongside. These are ideal for loading and unloading materials close to the ground. They have a tiller located on the side of the truck where all the controls are located. The operator manipulates the controls while he or she walks.
Classes IV, V, and VI are powered by LPG, diesel, or gasoline and have internal combustion engines. Class IV vehicles are equipped with solid, or cushion, wheels. Their main application is moving materials between the storage area and the loading dock. They are lower to the ground than vehicles with pneumatic tires and are suitable for low-clearance situations. They require smooth, dry surfaces.
Class V lifttrucks have the option of using compressed natural gas as a fuel, as well as LPG, gasoline or diesel. These are the most versatile of all the classes of lift truck and are consequently the most common. Class VI lifts are used in rough terrain.
