As environmental considerations and fluctuating oil prices continue to push consumers toward alternatives to traditional internal combustion engines, material handling operations increasingly look toward electric equipment solutions.

In operations that utilize forklifts, far more electric units are now sold than those powered by internal combustion engines. Electric forklifts now make up nearly 70 percent of all trucks sold, and with increasing demand for electric power comes a need to provide a solution that provides all of the benefits of traditional engines without a loss in productivity.

Lead acid batteries have been a capable but imperfect solution for years, and they continue to dominate the market today. It is estimated that lead acid batteries power 90 percent of electric forklifts in operation.

But a new player has emerged on the scene in recent years and is revolutionizing the way some companies do business. Lithium-ion battery (LiB) technology represents the next generation of forklift technology, and LiB market share in electric forklifts is expected grow significantly in the coming years.

But while LiB technology offers unique benefits, these batteries don’t make sense for every operation. You can use a new metric – Equivalent Battery Usage (EBU) – to help you decide if making the shift to LiB batteries is best for you.

EBU measures the number of cycles customers typically use their lead acid batteries per day. A common threshold for determining whether LiB makes sense for your operation is 1.6 times per day. If your operation’s EBU is above 1.6, LiB could be a potential fit for you. If it falls below 1.6, however, it probably makes more sense to continue using lead acid.

Typically, multi-shift applications are above the 1.6 EBU threshold – so any customer operating their equipment for more than one shift per day is a good candidate for considering LiB technology.

The reason LiB doesn’t make sense for every customer today is simple – the high upfront cost, and the high variability in return on investment. LiBs are more expensive than lead acid batteries, and they’re best used in high-throughput applications – such as distribution facilities, retail, and paper industries.

Running a material handling business is a tall task – not only do you have to monitor your product, your sales, and your employees, you also have to ensure your forklift fleet is operating at its best capacity. Malfunctioning and overheating forklifts can skyrocket your operating costs and require expensive repairs. So what do you do if you’ve followed all maintenance suggestions and they are still overheating? Here are three areas that may be the cause of your forklift running hot:

Maintenance

The first area to check is also the easiest to fix: are routine maintenance tasks being completed correctly? Issues such as low coolant levels or worn hoses can contribute to a forklift’s overheating. If your on-site tech stretches parts past their optimal use, such as clogged filters, your forklifts could be choking on thick, dusty air. Worn fans or damaged radiators can also contribute to high running temperatures in material handling equipment.

Environment

The same advice for workers in high temperatures applies to your forklifts – give them frequent breaks and make sure their fluids are topped off.

Is your work yard paved or on packed dirt? Excessive dust, debris, and rough terrain can put additional demands on your forklifts and cause unforeseen maintenance problems. If this is a recurrent summer problem then the outside temperature can even be to blame. The same advice for workers in high temperatures applies to your forklifts – give them frequent breaks and make sure their fluids are topped off. If your forklifts are overheating indoors then you’ll want to survey your work area to find issues. Is the floor dusty or dirty? Are pieces of paper, pallet wrap, or other debris being left on the ground where they can clog filters? Once you find these issues then you can optimize your work areas to prevent damage.

Operation

If it’s not maintenance or environmental issues causing your overheating problems, then you need to check on how you are driving the equipment. If you are overloading the forklift with loads above capacity, this can cause overheating and create unnecessary risks for product damage and accidents. Are you driving forklifts constantly at top speeds? This can also contribute to high heats.

Many IC forklifts come equipped with an inching pedal to use when maneuvering your forklift while raising the mast to retrieve loads. If you are “riding” this pedal while driving it can cause many problems, as it slightly applies the brakes. The inching pedal should only be used when retrieving loads.

Once you’ve identified the cause of the problem and put a fix in place, ask why it arose in the first place. Are you overworking forklifts due to high expectations? Should your work area floor upkeep be added to existing maintenance plans? Don’t just solve the problem. Find a solution to keep it from happening again.
