Class Vocabulary

Term	Definition
aisle sideloader	A type of powered industrial truck designed for use in narrow spaces, such as warehouses.
attended vehicle	A PIT with an operator either on board or within a given number of feet of the PIT while it is running.
capacity	The maximum amount of volume or weight that can be safely contained or handled. The capacity of a PIT is listed on a metal plate that is attached to the vehicle.
center of gravity	The point at which all the surrounding weight is equal. It is the point at which an object is in balance.
combined center of gravity	On a forklift, it is the point at which the vehicle weight and the load weight combine. When the combined center of gravity is within the vehicle's stability triangle, the PIT will not tip.
counterbalance	To balance one weight with another. Counterbalancing increases stability.
counterweight	A weight that is used to counterbalance a heavy load. The forklift's own weight acts as a counterbalance to a load, but additional weight may be added for greater counterbalancing.
data plate	A metal plate affixed to the vehicle by the manufacturer that contains information such as the weight of the vehicle.
distribution	The method that the weight of a load is spread over the lifting device.
dynamic stability	A forklift’s ability to stay upright while in motion. When the vehicle is moving, braking, turning corners, lifting, tilting, or otherwise moving, various forces can act on the load and vehicle to make it less stable and more likely to tip over.
electric-powered industrial truck	A type of powered industrial truck or forklift that runs on electricity.
Fair Labor Standards Act	The federal law which sets minimum wage, overtime pay, equal pay, record keeping, and the child labor standards for employees.
forklift	A type of powered industrial truck that has two prongs on the front for lifting pallets of material. Forklifts are one of the most common types of PIT.
fulcrum	A pivot point of a lever, or the point around which an object turns.
inch pounds	The recommended number of pounds per square inch that the vehicle should carry.
internal-combustion-engine-powered industrial truck	A type of powered industrial truck that runs on gasoline, liquefied petroleum gas, or diesel fuel.
lateral stability	The ability of a PIT to remain upright and not tip over sideways. A load that is out of balance or on an uneven traveling surface can affect lateral stability.
liquefied petroleum gas	Fuel made from propane, butane, or a mixture of both.
load backrest extension	The back wall on the lifting portion of the forklift that lies perpendicular to the forks or platform. The load backrest extension prevents the load from falling backwards onto the driver.
load center	The horizontal space that exists between the edge of the load and the vertical stability line. The load center is the distance portion of the moment principle.
longitudinal stability	A PIT's ability to resist tipping forward. When vehicle weight exceeds load weight, longitudinal stability generally exists.
manifest	A list of goods or materials being transported by truck, train, or other means. The manifest usually includes details such as the size, weight, and contents of the objects or substances.
mast	The vertical portion of the lift mechanism that raises the load into the air.
moment	A force that attempts to produce motion around a given point or fulcrum. Moment is the combination of weight and distance from the fulcrum.
momentum	Mass multiplied by velocity, or the combination of weight and motion. Excessive momentum can cause a vehicle to tip.
nonagricultural industries	Those industries, such as manufacturing, that do not involve growing or harvesting food products.
noncombustible agent	A substance that will not catch fire or explode.
Occupational Safety and Health Administration	A government agency under the U.S. Dept. of Labor that helps employers reduce injuries, illnesses, and deaths in the workplace.
overhead guard	The upper portion of the body of the vehicle that serves as a type of roof or rollbar. The overhead guard protects the operator from falling loads.
pallet	A low, portable platform made of wood, metal, or plastic on which goods and materials are stacked for storage or transportation. Pallets are also known as skids.
pallet lift	A type of powered industrial truck used to raise wooden or metal platforms or pallets on which objects or materials are resting.
pivot pin	The point on the rear axle of a forklift that transfers the motion of the steering wheel to the wheels to change their direction.
powered industrial truck	Any mobile, power-propelled truck, other than an earth-moving or road-hauling vehicle, that is capable of carrying, pushing, pulling, lifting, or stacking materials. A forklift is a common type of PIT.
rated capacity	The manufacturer's guidelines for how much weight a PIT can safely carry.
see-saw	A long, narrow board balanced in the middle on a fulcrum in such a way that, as one end goes up, the other goes down.
stability	The ability of a PIT to remain upright. Stability is the most important factor necessary for avoiding accidents.
stability triangle	The area on a forklift in which the load must be suspended in order for the forklift not to tip. The vehicle's center of gravity is within the stability triangle.
standard load center measurement	Half the distance from the inside edge of the forks or platform to the center. On a 48 in. platform, the standard load center measurement is 24 inches.
three-point suspension system	A device that is balanced or supported at three different locations. A forklift has a three-point suspension system.
track	The distance between the wheels on the same axle.
unattended vehicle	A vehicle that does not have an operator on board or within proximity. There are specific rules governing unattended vehicles, including how they should be secured.
vehicle height	The total vertical distance covered by the vehicle and mast at its highest extension.
vehicle wheel base	The distance between the centerlines of the vehicle’s front and rear wheels.
vertical stability line	An imaginary line drawn through the vehicle's center of gravity and the load's center of gravity.
