Cold stores and chilled environments create very different working conditions for forklift trucks.
Low temperatures, condensation, moisture and changes between chilled and ambient areas can all affect equipment performance. Choosing a forklift designed to cope with these conditions can therefore make a significant difference to reliability, productivity and maintenance requirements.
But what type of forklift works best in a cold store?
There isn’t a single answer for every application. The right choice depends on the temperature, operating hours, floor conditions, load requirements and whether the truck will be working entirely inside the cold store or moving between different environments.
Why Are Cold Stores Challenging for Forklifts?
Forklifts operating in chilled environments face conditions that aren’t normally encountered in a standard warehouse.
Cold temperatures can affect batteries, hydraulic fluids and other components, while moving between cold and warmer areas can create condensation.
The floor environment can also be challenging. Moisture and condensation may affect traction, while frozen surfaces can increase the risk of slipping.
For businesses operating cold stores, choosing suitable equipment and maintaining it properly is essential.
Are Electric Forklifts Suitable for Cold Stores?
Electric forklifts are commonly used in indoor environments and can be well suited to many cold-store applications.
They produce no direct exhaust emissions during operation, making them particularly appropriate for enclosed working environments.
However, cold temperatures can affect battery performance. Businesses should therefore consider the operating temperature specified for the battery and forklift, as well as how long the truck will spend working in the cold environment.
Lithium-ion technology can offer advantages in some applications, particularly where opportunity charging and high utilisation are important.
However, battery selection should always take the specific operating environment into account.
What About Diesel or LPG Forklifts?
Diesel and LPG forklifts may be appropriate for certain applications, particularly where trucks need to operate outdoors as well as inside.
However, businesses need to consider ventilation carefully when using internal combustion forklifts in enclosed or partially enclosed environments.
The suitability of any forklift will depend on the specific site, operating conditions and manufacturer’s recommendations.
For a business moving goods between an external yard and a chilled warehouse, for example, the priorities may be different from those of a forklift operating continuously inside a cold store.
What Should You Consider When Choosing a Cold Store Forklift?
Operating Temperature
The first consideration is the temperature the forklift will be exposed to.
A truck working in a mildly chilled environment may have very different requirements from one operating inside a freezer at significantly lower temperatures.
Always check the manufacturer’s specifications to ensure the equipment is suitable for the intended conditions.
Time Spent in the Cold
How long the forklift remains inside the chilled environment can also affect your choice.
A truck that spends most of its working day in a cold store will face different challenges from one that only enters occasionally to collect or deliver loads.
Battery Performance
For electric forklifts, battery performance is particularly important.
Cold temperatures can affect battery capacity and charging behaviour, so businesses should consider the battery technology, charging arrangements and operating schedule before choosing equipment.
Floor Conditions
Cold-store floors can become wet or slippery due to condensation, making traction particularly important.
The correct forklift tyres can help provide appropriate grip for the operating environment, while regular checks can identify excessive wear or damage before it becomes a problem.
Load Requirements
As with any forklift application, the truck must be capable of safely handling the required loads at the necessary lifting height.
The environment shouldn’t be the only factor influencing your decision. Load capacity, lift height, aisle width and manoeuvrability all need to be considered together.
Maintenance Is Particularly Important in Cold Environments
Forklifts working in chilled environments can experience additional wear, making regular maintenance particularly important.
Condensation and moisture can contribute to corrosion, while repeated temperature changes can place additional demands on certain components.
Regular inspections can help identify issues early, while planned forklift servicing ensures key systems are checked and maintained according to the manufacturer’s recommendations.
Operators should also report unusual noises, warning lights, reduced performance or other changes immediately rather than waiting for a fault to develop.
Moving Between Cold and Ambient Environments
Some cold-store forklifts regularly move between refrigerated areas and warmer warehouse or loading areas.
These changes in temperature can create condensation, which may affect electrical components and other parts of the truck.
Where possible, businesses should follow the manufacturer’s guidance on moving equipment between different temperature zones and allow appropriate procedures to be followed before returning equipment to service.
Don’t Forget Operator Safety
The working environment isn’t the only consideration in a cold store.
Operators may be working in low temperatures for extended periods, often with reduced visibility or busy traffic routes.
Good lighting, visibility, appropriate operator protection and clear pedestrian segregation should all form part of the wider workplace safety strategy.
Regular pre-use checks are also essential. Our daily forklift checklist provides a useful starting point for the areas operators should check before using their equipment.
Choosing the Right Forklift for Your Cold Store
The best forklift for a chilled environment depends on the application.
Before choosing equipment, consider:
- Operating temperature
- Time spent inside the cold store
- Load weights and dimensions
- Required lift height
- Aisle widths and manoeuvrability
- Battery technology and charging requirements
- Floor conditions
- Indoor and outdoor use
- Number of operating shifts
- Maintenance requirements
Getting the specification right from the beginning can help improve reliability, reduce downtime and ensure the forklift is capable of handling the demands placed upon it.
