Moving massive loads requires forklifts built for brute strength. That’s a HUGE factor, and these heavy-duty machines must deliver high horsepower and have reinforced lifting mechanisms to move heavy materials safely and efficiently. 

But power alone isn’t enough, and big forklifts also rely on stability and control to manage extreme weights. To answer this need, advanced hydraulics and counterweight systems maintain balance and prevent tipping. 

Lastly, torque, the engine’s twisting force, is integral to a heavy-duty truck’s performance. It allows the truck to lift heavy loads and manage rough terrain without overloading the truck. This blend of balance, power, and torque makes the lift indispensable to industries that need extra strength and durability. 

Besides lifting capacity, torque, and horsepower, here are some other factors to consider when buying a big forklift: 

• Height Requirements – Big forklifts need to reach the lifting height needed for high storage needs. 

• Fuel Type – Diesel, electric, and propane models all have varying operating costs, maintenance requirements, and environmental impact. 

• Attachments and Customization – Specialized forks, clamps, and booms can make your forklift versatile. This fact comes in handy when handling large irregularly shaped or oversized loads.  

• Operator Training and Safety – Larger forklifts require skilled operators. Ensure the operators have OSHA compliant forklift certification to the class of forklift they’ll be driving.  

• Long-term Costs – Beyond the purchase price, consider fuel, maintenance, parts availability, and potential downtime when calculating the total cost of ownership. 

• Maneuverability and Training Radius – Big forklifts need more space to move around. Verify your work environment can accommodate their size and movement.  

• Aftermarket Support – Consider availability of replacement parts, service agreements, and manufacturer support to keep your big truck running smoothly. 

The above points are a good starting point, but there are several others to consider based on your specific needs. A trusted partner like CLARK can help you through the process and find a forklift that fits your applications, budget, and work environment.

Big forklifts go through a lot more punishment than standard forklifts due to their extreme lifting capacity, rugged environment, and heavy-duty applications. As such, they require additional maintenance beyond standard checks of fluid levels, tire pressure, and battery   

Here are some important maintenance tips for heavy-duty forklifts:  

1. Check Tire Pressure Often
   Big forklifts carry huge loads and tires get extra stress, so check them often to prevent uneven wear and blowouts.
2. Change Engine Oil and Filters
   Regular oil and filter changes keeps the engine running smooth and prevents debris buildup.
3. Inspect Hydraulic System
   These vehicles run on high pressure hydraulics to lift heavy loads, so be vigilant for leaks, pressure changes and worn seals that they are prone to have. 
4. Check Brakes Often
   A forklift this size has to be equipped with powerful brakes for strong stopping power. Therefore, check brake pads, drums and hydraulic components.
5. Check Load Bearing Components
   Mast rollers, chains and lifting cylinders take a beating in a big lift. Check often to detect wear and prevent failures that can compromise safety.
6. Check Frame and Chassis
   Carrying oversized loads can cause stress fractures or metal fatigue. Look for cracks, warping or other signs of weakness.
7. Maintain Cooling System

Big forklifts generate more heat than regular ones. Checking coolant levels and radiator function will prevent overheating. 

8. Inspect Transmission and Driveline Components

Gear slippage or power transfer issues can reduce efficiency and put stress on the drivetrain. Monitor these components often to keep the truck running smoothly under heavy loads.

Evaluating how your equipment choices affect the environment is key to balancing operational needs with ecological responsibility. A 2021 study revealed that 44% of consumers value brands committed to sustainability and prefer doing business with them. However, operational demands may sometimes require prioritizing performance over environmental considerations.  

When deciding between an electric or diesel forklift, it’s important to weigh their environmental advantages against their operational suitability. Below is a breakdown of each type. 

Electric Forklifts 

Electric models are often the go-to choice for clean, quiet environments. They offer a range of advantages—but also a few limitations:  

• Zero Emissions – Electric forklifts produce no exhaust fumes, making them ideal for indoor use where air quality is a priority. Their performance may be less suitable for outdoor or heavy-duty applications, though. 

• Lower Noise Levels – These models operate quietly, which reduces noise pollution for indoor operations. In outdoor settings, this advantage tends to matter less.  

• Energy Efficiency – Electric models convert more energy into productive work.  However, their battery life depends on regular recharging, which can interrupt continuous operations. 

Diesel forklifts 

Diesel forklifts are built for power and durability in rugged environments. Here’s how they stack up:   

• High Power Output – Diesel models deliver the power and torque needed for heavy lifting and outdoor terrain. The trade-off is higher emissions, including nitrogen oxides and carbon monoxide.  

• Extended Operation – With fast refueling and long run times, diesel forklifts can operate continuously over long periods. This capability comes at the cost of increased fuel cost and environmental impact. 

• Rugged Durability – Designed for outdoor use, diesel trucks perform well on uneven, rugged terrain. However, their loud noise and emissions make them less suitable for indoor environments.  

Electric forklifts generally cost more upfront, but when it comes to long-term return on investment, electric forklifts often come out ahead—especially in indoor or light-duty applications. Lower fuel and maintenance costs, fewer service interruptions, and a cleaner operation all add up to savings and advantages over time.  

Diesel forklifts may be cheaper up front and better suited to outdoor, high demand tasks, but they require more maintenance and consume more fuel. a CLARK Dealer can help you compare every factor—cost, applications, and lifespans—so you can choose the model that fits your long-term business goals.  

Electric forklifts generally cost more upfront but tend to save money over time through less energy use. The maintenance on them is also simpler since there are not as many moving parts.   

Diesel forklifts, on the other hand, tend to offer lower initial costs and longer continuous run times. They use more fuel and typically require more intensive maintenance but are often preferred for outdoor operations due to key advantages such as greater lifting capacities and higher torque and horsepower.  

No operation is the same, and the right forklift for you depends on your specific needs. Start by looking at where and how often you’ll utilize the equipment. Then, think about the kind of loads you’ll be handling, and how much weight is involved. Noise levels, emissions, and run time can also be important factors.  

Electric models are great indoors and in quiet settings. Diesel forklifts are better suited for outdoor work and heavy-duty tasks. A CLARK Dealer can help you sort through these factors and others to find the best fit for your business.  

Electric and diesel forklifts play to different strengths, and the right one for you will depend on how you plan to use them. So, it’s not about choosing the best—it’s about picking what works best for your operation. Think about your day-to-day demands, budget, and long-term goals and take action.
