Forklifts are built to handle tough jobs—but even the most rugged machines feel the heat when summer rolls around. Rising temperatures, longer shifts, and increased demand can push your forklifts to their limits, leading to unexpected wear, performance issues, and costly downtime if not addressed.
Here’s how summer heat stresses your equipment—and how smart maintenance can keep your fleet running strong through the hottest months of the year.
1. Overheating Engines and Cooling System Strain
Internal combustion forklifts generate a lot of heat already. Add in 90+ degree weather and your cooling system has to work overtime. If radiators, coolant levels, or fans are neglected, you’re risking engine failure and costly repairs.
Tip: Clean radiator fins regularly, monitor coolant levels, and replace worn belts or hoses before they fail.
2. Battery Drain and Shortened Lifespan
For electric forklifts, heat can be just as damaging. High temperatures accelerate battery fluid evaporation, reduce charge efficiency, and shorten overall battery life.
Tip: Check fluid levels often, store forklifts in shaded or ventilated areas, and avoid overcharging batteries in extreme heat.
3. Tire Pressure Fluctuations
Hot weather causes air to expand, which can lead to overinflated pneumatic tires and weakened cushion tires. This increases the risk of blowouts or poor traction on hot warehouse floors.
Tip: Inspect tire pressure regularly, especially for outdoor equipment. Replace any tires showing signs of cracking or heat damage.
4. Hydraulic System Breakdown
High temperatures can thin hydraulic fluids, reducing effectiveness and increasing the chance of leaks or component failure.
Tip: Use manufacturer-recommended fluids and change them on schedule. Look for signs of wear or overheating in the hydraulic system during regular inspections.
5. Increased Workload from Summer Demand
In many industries, summer means busier operations. That higher demand puts more hours on your forklifts—and more stress on every part of the machine.
Tip: Stick to a strict maintenance schedule and consider rotating equipment to balance wear and tear across your fleet.
Protect Your Investment with Proactive Summer Maintenance
Don’t wait for a breakdown to realize your forklifts are overheating or underperforming. Regular inspections, seasonal service, and smart operating habits can help protect your fleet from the extra stress of summer.
