Top tips for operating forklifts in the summer heat

/in /by

Fork truck fleets are under increasing pressure as the peak summer months get underway. For forklifts in summer, lengthy heatwaves take their toll on lifting machines. It’s not particularly pleasant for operatives either. The current economic climate is hardly helping the situation right now so, before something gives, you need to get on top of both machine and operator welfare this sunny season.

Forklift operation can be adversely affected by rising temperatures and high levels of humidity. Add in increasing demands on warehousing as the Covid recovery continues, plus shortages in many industries ramping up the pressure, and it could just be that the perfect summer storm will see materials handling operations begin to creak.

That means some additional steps are needed to keep the motors running, the forks lifting and the goods moving.

Recognise the signs of forklift overheating

Overheating is a major problem for forklifts in the summer. Indoor-operating fork trucks can be subject to continuous high temperatures while those that work outside are exposed to long periods of sunlight beating down on them

A radiator in good working order and free from debris will help protect forklifts from overheating, while regularly checking coolant levels is essential. Inspect hoses for holes and leaks more frequently as high temperatures can make them more prone to cracking. Clogged filters also make overheating more likely, as do broken fan blades and loose fan belts.

Ensure operatives are fully briefed on recognising the signs that a forklift may be overheating. These include the temperature gauge moving into the red zone, steam coming from the engine compartment, backfiring or a loud growling noise during operation, and the cabin airflow becoming unusually warm. If any of those are noted, the fork truck should halt operations and maintenance personnel called.

Don’t let the battery die

Heat has several effects on a fork truck battery and they’re all negative. High temperatures lead to shorter battery life, so they’ll usually need replacing more often in summer than winter. Heat also causes battery fluids to evaporate so you’ll need to check the levels in the cells frequently.

If water levels are low in older lead-acid batteries, be sure to top up with water that is pH-neutral, distilled and deionised. You’ll likely need to increase the frequency of battery watering throughout the day in hot weather.

Check the tyres regularly

For forklifts in summer the heat can cause forklift tyres to crack. It can also lead to the rubber softening and this, combined with dusty conditions in dirty environments, can quickly result in the tyre sidewalls becoming more prone to damage and failure.

The air inside a fork truck tyre will also expand when it’s warm, causing higher pressure and a greater risk of a blow out. Conduct daily checks of tyre pressure – more when it’s particularly hot and inspect all surfaces for signs of cracking and excessive wear.

Pay attention to the lifting gear

As with all fluids, hydraulic fluid will evaporate more easily in hot conditions. Regularly check the levels to prevent the increased risk of forklift hydraulic systems seizing up and breaking down.

If the Great British weather reverts to type and we experience unpredictable conditions with large swings from cool days and nights to baking hot periods, the big shifts in temperature can play havoc with the sturdiness of cables, chains and connectors so have them examined regularly.

Overworked fork trucks in the long hot summer of ‘22

Aside from an impeccable preventative maintenance programme – which will keep you on top of everything above – a major cause of fork truck breakdown and overheating in the summer is simply overworking the machine itself. And spare a thought for its operator too.

In these times of soaring demand, supply chain issues and shortages in everything from commodities to construction materials, food products to labour, the demands on warehouses, fork trucks and staff are enormous. Plus, it’s a simple fact that working in summer can be exhausting for both humans and machines.

A revised inspection and servicing regime with increased frequencies, coupled with regular breaks and topped-up fluids for both truck and operator throughout the day are essential to avoid a complete meltdown.

What do you need to do for your forklifts during the summer months?

/in /by

In England, most of us cannot wait for when the summer months are upon us, and the weather is finally getting warmer. However, for those of us using forklifts in this extreme heat, it can become tough. Since warm weather can begin to take a toll on your heavy equipment, it’s important that you know what you need to do to make sure your forklift stays in good shape and the things to look out for if it is not. Whether that’s an overheating engine, your tires feeling a little too bouncy, or a run-down battery, here are a few cautionary checks and tips for your forklifts this summer.

Regularly check the battery

Whilst this seems pretty obvious, not many people know that the summer weather can affect your forklift battery and can actually reduce its life span. This is because as temperatures change and the sun starts beaming down on your forklift, it can actually cause the battery fluids to evaporate leading to corrosion.

For this reason, especially in the summer months, you must make sure to regularly check your battery’s fluid levels and top them up with water if need be.

Cool your engine down

On a hot summer day, it’s a good idea to monitor your engine’s running temperature to look out for overheating. If you find it is too hot, turn it off immediately and let it cool down before using it again.

Better yet, find a bit of shade to help speed up the cooling process and ensure minimal damage to your forklift. Just as the heat affects us when we are in it too long, it also affects your forklift, so they need the same care and attention in the heat as we do.

Check for damage to the fan

When trying to make sure your engine does not overheat, checking the fan is the first thing to do. Since all engines rely on a fan to keep them cool on a regular day, during the summer months the fan will often be working overtime to ensure your forklift is not getting too hot.

Check the fan every day for cracks and if you notice anything make sure to get it fixed as soon as possible to avoid damage caused by overheating.

Check your fluid levels

When using a forklift in extreme heat, it’s very important to ensure that your coolant levels are not running low. If coolant levels do run below the minimum this will need to be fixed right away as it can then lead to damage to the engine, causing a vicious circle.

To be safe, regularly check all fluid levels including the oil, and ensure that hoses are fully intact to make sure that your coolant is not leaking.

Look after your operators

Whilst there are many things to look out for to ensure your forklift is running smoothly during summer, it is the operators who are responsible for this, so keeping them safe in the scorching heat will also benefit the process.

Taking precautionary measures towards your operators will protect both them and your forklift and prevent the slowing down of productivity.

To beat the heat, make sure that your operators avoid heat exhaustion by ensuring they are well-rested before taking on the job. It is also extremely important that when your forklift is taking a break from the sun, so are the operators, by taking a well-deserved time out in the shade.

Just as a forklift needs to have its coolant fluid levels checked, operators also need to make sure they are fully hydrated to allow them to have enough energy to carry out the job and keep them safe in the warm weather.
