Class VII: Rough Terrain Forklifts

This class includes telehandlers, straight mast rough terrain forklifts, and other rugged types of forklift trucks built for unstable surfaces. They’re indispensable in construction, agriculture, and any setting where terrain is unpredictable.

• Power Source: Diesel
• Tires: Large pneumatic, high-clearance
• Use Case: Outdoor construction sites, farms, logging operations
• Capacity Range: 5,000–36,000 lbs.
• Key Benefits: High ground clearance, 4WD capability, extreme durability

Understanding these forklift classifications is the first step in choosing the right machine. Next, we’ll look at the most common and practical types of forklifts you’ll encounter and what they’re best suited for.

 

Most Common Forklift Types (and Where They Work Best)

Beyond official classifications, it’s helpful to break down the different types of forklifts based on how they’re actually used on job sites, in warehouses, and in outdoor environments. These are the forklift types and names you’ll hear most often in real-world operations, and each comes with its own strengths.

1. Counterbalance Forklift

What It Is:
The most recognizable type of forklift, counterbalance models have forks in front and a heavy counterweight in the back to balance the load.

Best For:

• Indoor and outdoor use
• Warehouses, docks, manufacturing
• General-purpose lifting up to 12,000+ lbs.

Why It Matters:
If you only have room for one forklift, this is often the go-to. It’s versatile, easy to operate, and compatible with various attachments.

Forklift types covered: Class I, IV, V

2. Reach Truck

What It Is:
A compact type of forklift truck designed to extend its forks forward to "reach" into warehouse racking.

Best For:

• Indoor use
• Narrow aisle storage
• Lifting to high shelves (30+ feet)

Why It Matters:
Ideal for warehouses trying to maximize vertical space. Not suited for outdoor or uneven surfaces.

Forklift types covered: Class II

3. Pallet Jack (Manual & Electric)

What It Is:
A basic, low-lift truck for moving pallets, manually operated or battery-powered.

Best For:

• Loading docks
• Stock rooms
• Short-distance moves on flat floors

Why It Matters:
These forklift models are small, simple, and essential for moving palletized goods quickly and safely in tight areas.

Forklift types covered: Class III

4. Order Picker

What It Is:
An operator-up forklift type that raises both the load and the operator to retrieve individual items from racks.

Best For:

• Warehousing and e-commerce
• Picking inventory from multiple shelf levels
• High-density racking systems

Why It Matters:
Perfect for operations where efficiency and picking accuracy are critical. Not for moving entire pallets.

Forklift types covered: Class II

5. Telehandler (Telescopic Handler)

What It Is:
A cross between a forklift and a crane, using a telescoping boom to extend forward and upward.

Best For:

• Construction and agriculture
• Lifting loads to rooftops, balconies, etc.
• Uneven terrain

Why It Matters:
One of the most adaptable different kinds of forklifts, telehandlers can reach places traditional masts can’t, with the lifting power to match. This comparison between a telehandler and a forklift breaks down the key differences in reach, capacity, and jobsite versatility so you can choose the right machine for your needs.

Electric vs Internal Combustion Forklifts

One of the biggest decisions when choosing between different types of forklifts is whether to go electric or internal combustion (IC). Each has advantages depending on your work environment.

Electric Forklifts

• Best for indoor use
• Lower operating costs over time
• Zero emissions
• Quieter operation
• Requires battery charging infrastructure

Internal Combustion Forklifts

• Best for outdoor or heavy-duty work
• Longer run times without recharging
• Higher lifting capacities available
• Requires ventilation if used indoors
• Runs on LPG, diesel, gasoline, or CNG

Understanding the power source is just as important as understanding forklift classifications. The wrong choice can increase costs, reduce efficiency, or create safety concerns in your workspace.

Choosing the Right Forklift for the Job

It’s not just about what the machine can lift; it’s about where and how you’re using it. Matching the right type of forklift to your work environment ensures better safety, higher productivity, and fewer breakdowns.

Here’s how to make the right call based on your jobsite conditions:

Indoor vs Outdoor Use

Indoor Jobs: Choose electric forklifts (Class I, II, III) with cushion tires for smooth concrete surfaces. These are ideal for warehouses, distribution centers, and retail settings.

Outdoor Jobs: Go with IC forklifts (Class V or VII) with pneumatic tires. They can handle uneven terrain, dirt, gravel, and weather exposure.

Tight Spaces or Wide-Open Areas?

Narrow Aisles: Use narrow aisle forklifts like reach trucks or order pickers (Class II). They’re built for maneuverability and vertical lift.

Wide Open Yards:  Opt for counterbalance or rough terrain forklifts that have room to move and turn freely.

What Are You Lifting?

Palletized Goods: Pallet jacks and walkie stackers are often enough, especially for short, repetitive tasks.

Long, Bulky Materials (Lumber, Pipes): Side loaders or telehandlers are your best bet, depending on load size and terrain.

Heavy Loads: Need to move 10,000 lbs. or more? Look for higher-capacity Class V forklifts or telehandlers designed for tough jobs.

Surface Conditions

Smooth Floors: Cushion tires are better for stability and tight turns.

Uneven or Rough Terrain: Pneumatic tires and rough terrain forklift types (Class VII) offer more grip and clearance.

Work Hours & Runtime

Short Shifts or Light Use: Battery-powered forklifts are a clean, efficient choice.

Long Shifts or Remote Sites: Internal combustion models can run all day with quick refueling, making them ideal for high-demand operations.

It’s important to weigh all these factors, not just capacity or price. The right fit means fewer delays, safer operation, and lower long-term costs.
