Forklift classes categorize industrial trucks based on power sources, design, and applications. The seven OSHA-approved classes (I-VII) include electric motor riders, internal combustion engine trucks, and specialized equipment. Each class serves unique purposes, such as narrow aisle operations or heavy outdoor lifting. Proper classification ensures safety, compliance, and equipment optimization in warehouses, construction, and manufacturing.

How Does OSHA Classify Forklift Types?
OSHA groups forklifts into seven classes. Class I covers electric motor rider trucks, while Class II includes electric narrow aisle models. Class III features electric hand/pallet trucks, and Class IV-VII comprise internal combustion forklifts with cushion or pneumatic tires. This system standardizes training, maintenance, and operational safety protocols across industries.
The classification system also accounts for specialized equipment variants. Class V forklifts (internal combustion engine trucks with pneumatic tires) are specifically designed for outdoor applications like lumber yards or construction sites, while Class VII rough-terrain forklifts feature reinforced frames and all-wheel drive for unstable surfaces. OSHA requires facilities to display classification decals visibly on all equipment and maintain separate inspection logs for each class.
When Should You Choose Electric vs. Internal Combustion Forklifts?
Electric forklifts (Classes I-III) suit indoor operations with zero emissions and lower noise. Internal combustion models (Classes IV-VII) handle outdoor/rough terrain tasks using diesel, propane, or gasoline. Consider fuel costs, maintenance frequency, and load capacity—electric trucks typically lift 3,000-8,000 lbs versus IC’s 15,000+ lb capacity.
What are the classifications of forklifts?
Forklifts are classified based on their design and use. The main types include electric, internal combustion, rough terrain, and pallet trucks. Each category is further divided into classes (Class I to Class VII) by the American National Standards Institute (ANSI) for specific environments and needs.
What is a B1, B2, and B3 forklift licence?
A B1, B2, and B3 forklift license refers to the specific classifications for operating different types of forklifts in the UK. B1 covers standard counterbalance forklifts, B2 is for reach trucks, and B3 is for articulated trucks. Each requires proper training and certification.
How does OSHA classify forklifts?
OSHA classifies forklifts into seven categories based on their power source and design, including electric, LPG, and diesel models. The categories range from Class I (electric motor riders) to Class VII (rough terrain vehicles), helping define their use in various industrial environments.
What are the 10 common forklift types classifications and uses?
Forklifts are classified into 10 types:
-
Counterbalance forklifts
-
Reach trucks
-
Order pickers
-
Pallet jacks
-
Rough terrain forklifts
-
Side loaders
-
Telescopic forklifts
-
Tow tractors
-
High-lift pallet trucks
-
Stackers
Each type serves different warehouse, construction, and material handling needs.
Why Does Forklift Training Vary by Class?
OSHA mandates class-specific training due to operational differences. For example, Class 4-7 training includes fuel handling, while Class 2 requires narrow aisle maneuvering certification. Training duration ranges from 8 hours (basic) to 40+ hours (specialized), covering load charts, stability triangles, and class-specific accident statistics.
How Do Maintenance Requirements Differ Across Classes?
Electric forklifts need battery watering systems and charger maintenance every 150-200 cycles. IC models require oil changes every 200 hours and spark plug inspections. Class 5 trucks demand tire pressure checks daily due to pneumatic systems, while Class 1’s cushion tires need replacement only when worn to the base line.
| Class | Maintenance Task | Frequency |
|---|---|---|
| I-III | Battery Watering | Weekly |
| IV-VII | Oil Change | 200 Hours |
| V | Tire Pressure Check | Daily |
Hydraulic system maintenance shows significant variation – electric models require fluid changes every 1,000 hours versus 500 hours for combustion engines. Class VII forklifts need additional drivetrain inspections due to extreme operating conditions.
“Understanding forklift classes isn’t just regulatory compliance—it’s operational optimization. At Redway, we’ve seen 23% productivity gains when companies match equipment classes to specific tasks. The emerging trend? Hybrid Class I/IV trucks that switch between electric and propane power, reducing downtime during mode transitions.”
