A Class 5 forklift is an internal combustion engine (ICE) truck with pneumatic (air-filled) tires. It is one of the seven classifications for powered industrial trucks established by the Occupational Safety and Health Administration (OSHA) and the Industrial Truck Association (ITA).
Key Characteristics
Class 5 forklifts are defined by the following features:
Power Source: Powered by an internal combustion engine that runs on diesel, gasoline, liquid propane (LP) gas, or compressed natural gas (CNG).
Tires: Equipped with pneumatic (air-filled) tires, which provide excellent traction and stability on uneven surfaces.
Operator Position: The operator sits on the truck in a cab with seated controls.
Counterbalance: They are counterbalanced, meaning the weight at the back of the truck offsets the load in the front to provide stability.
Typical Applications
Due to their pneumatic tires, Class 5 forklifts are designed for both indoor and outdoor use, making them one of the most widely used forklift classes. Common applications include:
Outdoor yards and construction sites
Warehouses and distribution centers requiring indoor/outdoor flexibility
Heavy-duty lifting and demanding material handling operations
Benefits
Versatility: Pneumatic tires allow operation on a wide range of surfaces, from smooth concrete to gravel and dirt.
High Performance: Internal combustion engines provide reliable power for heavy loads and demanding applications.
Excellent Traction: Pneumatic tires offer superior grip on uneven or slippery surfaces.
Common Fuel Options
Class 5 forklifts are available with several fuel types:
Diesel
Gasoline
Liquid Propane (LPG)
Compressed Natural Gas (CNG)
How Class 5 Differs from Class 4
The primary difference between Class 5 and Class 4 forklifts is the type of tires:
Feature Class 4 Forklift Class 5 Forklift
Tire Type Cushion (solid) tires Pneumatic (air-filled) tires
Primary Use Indoor use on smooth, flat surfaces Indoor and outdoor use on various surfaces
Terrain Smooth concrete or asphalt Uneven, rough, or unpaved surfaces
Class 4 forklifts are designed primarily for indoor applications with smooth floors, while Class 5 forklifts offer the flexibility to operate both indoors and outdoors on a wider range of surfaces.
Summary
A Class 5 forklift is an internal combustion engine truck with pneumatic tires, offering the versatility to operate effectively both indoors and outdoors on various surfaces. Powered by diesel, gasoline, LPG, or CNG, these counterbalanced, sit-down rider trucks are among the most widely used forklift classes due to their excellent traction, stability, and heavy-duty lifting capabilities.
