Australia’s summers are known for their intense heat, especially in Sydney and the greater New South Wales region. For businesses that rely on forklifts daily, soaring temperatures pose a serious challenge. Excessive heat impacts machine performance, accelerates wear, and can even lead to breakdowns, resulting in lost time, money, and operational efficiency.
At Forkserve, we have spent decades helping Sydney businesses keep their forklift fleets running reliably through harsh Australian summers. In this guide, we offer expert advice to help you keep your forklifts operational in extreme weather and protect your investment.
Why Summer Heat is Hard on Forklifts
Forklifts, like any heavy machinery, operate within specific temperature ranges. High summer temperatures in Australia can cause:
- Engine overheating
- Battery degradation
- Tyre failures
- Hydraulic fluid breakdown
- Cooling system malfunctions
- Increased wear on seals and hoses
Without proactive maintenance and operational adjustments, your forklift fleet is at greater risk during the hottest months.
Common Heat-Related Forklift Issues
1. Overheating Engines
High ambient temperatures put extra pressure on forklift engines, particularly diesel models operating outdoors. Poor cooling system maintenance can lead to overheating, breakdowns, and costly repairs quickly.
2. Battery Failures in Electric Forklifts
Batteries in electric forklifts are sensitive to heat. Temperatures above 30°c can reduce battery life, accelerate discharge, and even damage internal components.
3. Hydraulic System Problems
Hydraulic fluids thin out at higher temperatures, reducing lifting power, increasing leak risks, and accelerating wear on seals and cylinders.
4. Tyre Blowouts and Premature Wear
Heat causes forklift tyres to expand and weaken, especially pneumatic tyres. Underinflated tyres can suffer catastrophic failures if not appropriately managed.
Pre-Summer Forklift Maintenance Checklist
Before summer arrives, ensure your forklift fleet is fully prepared with these essential maintenance tasks:
1. Inspect and Service the Cooling System
- Check coolant levels and top up if necessary.
- Inspect radiator hoses and belts for cracks.
- Clean the radiator to remove dust and debris.
At Forkserve, we recommend coolant flushes before the start of each summer season for diesel and LPG forklifts.
2. Test Batteries and Charging Systems
- Inspect battery terminals and cables.
- Check fluid levels in lead-acid batteries.
- Perform a load test to assess battery health.
Proactive battery maintenance prevents costly breakdowns during peak operational periods.
3. Change Hydraulic Fluids if Needed
- Use hydraulic fluids rated for higher temperatures.
- Inspect hoses and seals for early signs of wear and tear.
Fresh, high-quality hydraulic fluid ensures consistent lifting performance in the heat.
4. Check and Maintain Tyres
- Inspect for cracks, cuts, or unusual wear.
- Check and adjust tyre pressures according to the manufacturer’s recommendations.
- Consider using solid tyres for high-temperature environments.
Proper tyre maintenance protects your forklift’s handling, safety, and load-carrying capability.
Summer Operational Best Practices
Maintenance is only part of the solution. Adjusting operational practices during summer can further extend forklift life and protect your business operations.
1. Schedule Operations Strategically
Where possible, operate forklifts during cooler parts of the day — early morning or late afternoon. Reduce workload during peak heat periods.
2. Monitor Engine and Battery Temperatures
Install temperature gauges or utilise built-in monitoring systems to track overheating risks in real-time.
3. Train Operators to Spot Warning Signs
Operators should be trained to recognise signs of overheating, including unusual smells, warning lights, or reduced performance.
4. Provide Shaded Parking
Where feasible, park forklifts under shade structures to prevent unnecessary heat buildup during breaks.
5. Keep Work Areas Clear
Dust, debris, and obstructions around cooling intakes can significantly reduce cooling efficiency. Keep operational areas clean and well-ventilated.
Special Considerations for Different Forklift Types
Diesel and LPG Forklifts
- Cooling system maintenance is critical.
- Regular engine inspections recommended.
- Check for exhaust system issues that worsen with heat.
Electric Forklifts
- Battery cooling must be a priority.
- Reduce continuous operation time to prevent heat accumulation.
- Charge batteries in well-ventilated, cool areas.
The Risks of Ignoring Summer Forklift Maintenance
Neglecting forklift maintenance and operational adjustments during summer can result in:
- Costly mechanical failures
- Extended downtime and operational disruption
- Shortened forklift lifespan
- Voided warranties due to maintenance non-compliance
- Increased workplace safety risks
Forkserve offers preventative maintenance services to keep Sydney forklift fleets running smoothly through the most challenging summer conditions.
