A Class 5 forklift is a type of internal combustion (IC) forklift equipped with pneumatic tires, designed for heavy-duty outdoor and indoor applications.
According to the classification system defined by the Occupational Safety and Health Administration (OSHA), Class 5 forklifts are known for their power, durability, and ability to operate on rough or uneven surfaces, making them one of the most widely used forklift types in industrial and outdoor environments.
What Is a Class 5 Forklift
What Defines a Class 5 Forklift?
Class 5 forklifts are powered by internal combustion engines, typically using diesel, gasoline, or LPG, and are equipped with pneumatic (air-filled) tires.
Key features:

- Pneumatic tires for outdoor use
- High load capacity and durability
- Suitable for both indoor and outdoor environments
👉 These forklifts are designed for versatility and heavy-duty performance.
What Are Pneumatic Tires?
Pneumatic tires are air-filled tires similar to those used on trucks or cars, designed to provide better traction and shock absorption.
Benefits of pneumatic tires:
- Handle rough and uneven terrain
- Provide better grip outdoors
- Absorb shocks for smoother operation
- Suitable for gravel, dirt, and asphalt
👉 This is the key feature that differentiates Class 5 forklifts from Class 4 forklifts.
