Forklifts are organized into seven distinct classes, primarily defined by the Occupational Safety and Health Administration (OSHA). These classifications are based on factors like power source, tire type, and intended application. Understanding these classes is crucial for selecting the right equipment and ensuring operator safety.
Here is a breakdown of the seven forklift classes:
Class Name Common Examples Key Features & Applications
Class I Electric Motor Rider Trucks Sit-down and stand-up counterbalanced forklifts Battery-powered, zero emissions, quiet operation. Ideal for indoor warehouses and general material handling.
Class II Electric Motor Narrow Aisle Trucks Reach trucks, order pickers, turret trucks Designed for tight spaces and high-density storage. Maximizes warehouse space without needing to expand.
Class III Electric Motor Hand or Hand/Rider Trucks Powered pallet jacks, walkie stackers Walk-behind or ride-on models. Used for low-lift, short-distance pallet movement on warehouse floors.
Class IV Internal Combustion Trucks (Cushion Tires) Counterbalanced forklifts with solid tires Powered by gas, LPG, or diesel. Cushion tires are for smooth, indoor surfaces.
Class V Internal Combustion Trucks (Pneumatic Tires) Counterbalanced forklifts with air-filled tires Similar engines to Class IV, but with pneumatic tires for better traction. Versatile for both indoor and outdoor use on uneven surfaces.
Class VI Electric and Internal Combustion Engine Tractors Tow tractors, tuggers Primarily used for pulling loads (like trains of carts) rather than lifting them. Common at airports and in assembly lines.
Class VII Rough Terrain Forklift Trucks Telehandlers, construction forklifts Large, heavy-duty pneumatic tires and high ground clearance. Designed for rugged outdoor conditions on unimproved surfaces like construction and logging sites.
While seven is the standard number of forklift classifications, some organizations or standards may define eight distinct classes, which can include specialized equipment like container handlers.
In short, forklift classifications are essential for identifying the right machine for the job, from Class I electric warehouse trucks to Class VII rough terrain workhorses.
