Forklift classes define industrial trucks by power source, design, and application. OSHA recognizes seven classes, ranging from electric motor riders to rough-terrain internal combustion forklifts. Each class has distinct advantages, whether for indoor warehouses, narrow aisles, or heavy outdoor lifting. Proper selection improves efficiency, safety, and operational longevity in warehouses, manufacturing sites, and construction projects.
How Does OSHA Classify Forklift Types?
OSHA categorizes forklifts into seven classes to standardize safety, training, and operational procedures:
| Class | Type | Power Source | Primary Use |
|---|---|---|---|
| I | Electric Motor Rider Trucks | Electric | Indoor warehouses, docks |
| II | Electric Motor Narrow Aisle Trucks | Electric | Tight spaces, high-shelf storage |
| III | Electric Hand or Hand/Rider Trucks | Electric | Short-distance indoor material handling |
| IV | IC Engine (Cushion Tires) | Diesel, Gas, LPG | Smooth indoor surfaces |
| V | IC Engine (Pneumatic Tires) | Diesel, Gas, LPG | Indoor/outdoor, versatile surfaces |
| VI | Electric/IC Tractors | Electric or IC | Towing/pulling heavy loads |
| VII | Rough Terrain Forklifts | Diesel | Outdoor, uneven terrain |
Specialized classes such as Class V and VII are tailored for outdoor or rugged operations, while Classes I-III excel in indoor, emission-sensitive environments. OSHA mandates clear classification decals and separate inspection logs for each class.
When Should You Choose Electric vs. Internal Combustion Forklifts?
Electric forklifts (Classes I-III) are ideal for indoor operations due to zero emissions, lower noise, and reduced maintenance costs. Internal combustion models (Classes IV-VII) perform best outdoors or on rough terrain, using diesel, propane, or gasoline. Load capacity is another key factor: electric trucks lift between 3,000–8,000 lbs, while IC forklifts handle 15,000 lbs or more.
Redway Battery’s lithium forklift solutions ensure electric models maintain full performance across long shifts, making them an optimal choice for modern warehouses seeking sustainability and reliability.
What Are the Classifications of Forklifts?
Forklifts are classified primarily into electric, internal combustion, rough terrain, and pallet truck categories. Each category is further divided into OSHA-approved classes I through VII to match specific operational environments and tasks. This classification ensures optimal safety, efficiency, and equipment longevity.

What Is a B1, B2, and B3 Forklift Licence?
In the UK, forklift licenses correspond to different operational classes:
B1: Standard counterbalance forklifts
B2: Reach trucks
B3: Articulated trucks
Each license requires specific training and certification to ensure safe handling of the respective equipment types.
Why Does Forklift Training Vary by Class?
Training varies due to operational complexity. Classes IV-VII involve fuel handling and heavy lifting, while Class II requires narrow aisle maneuvering skills. Training duration can range from 8 to 40+ hours, covering load charts, stability triangles, and class-specific safety procedures.
How Do Maintenance Requirements Differ Across Classes?
Maintenance schedules depend on power source and tire type:
| Class | Maintenance Task | Frequency |
|---|---|---|
| I-III | Battery watering | Weekly |
| IV-VII | Oil change | Every 200 hours |
| V | Tire pressure check | Daily |
Hydraulic fluid replacements differ as well: electric forklifts require changes every 1,000 hours, while internal combustion engines need them every 500 hours. Class VII forklifts require additional drivetrain inspections due to rough terrain usage. Redway Battery provides integrated battery management systems that simplify electric forklift upkeep and extend lifespan.
