The forklift class system, defined by OSHA, sorts every powered industrial truck into one of seven categories. Understanding these classes helps you choose the right machine for your environment and loads, and it matters for safety: OSHA operator certification is specific to the class and type of truck a person is trained on. Below is a breakdown of all seven classes.

Class I

Electric Motor Rider Trucks

Electric-powered sit-down and stand-up rider forklifts with cushion or pneumatic tires, used for indoor warehousing, loading docks, and general material handling. Clean and quiet, they are a staple of modern indoor operations.

Frequently Asked Questions

How many classes of forklifts are there?

OSHA classifies powered industrial trucks into seven classes (Class I through Class VII), based on their power source, tires, and design. The classes range from electric indoor rider trucks to rough-terrain outdoor machines.

Why do forklift classes matter?

The class system helps buyers and operators match the right truck to the job and environment, and it is tied to OSHA operator training, since certification is specific to the type of truck a person is trained to operate.

Which forklift class do I need?

It depends on your environment and loads. Indoor smooth-floor work often points to Class I, IV, or narrow-aisle Class II; outdoor and rough surfaces point to Class V or VII. Tell us your needs and we will match you with dealers who can recommend and quote the right class.
