Forklifts are categorized into different classes based on their power source, design, and intended use. Understanding these classifications is essential for choosing the right equipment, improving operational efficiency, and ensuring workplace safety.
In the United States, forklift classifications are defined by the Occupational Safety and Health Administration (OSHA), which divides forklifts into seven classes (Class 1–7).
This guide explains each forklift class, its features, and when to use it—helping you make the right decision for your business.
