A customer may find the right electric pallet stacker capacity and lift height, only to discover that the machine does not fit comfortably in the warehouse aisle.
This is why turning radius and aisle width should be checked before ordering an electric pallet stacker.
For a typical walkie electric pallet stacker, the minimum turning radius may be around 1,300–1,500 mm depending on the model. Published specifications show examples such as approximately 1,342 mm for a 1.5-ton CDD15 and approximately 1,494 mm for a 2-ton walkie stacker.
But the turning radius alone does not tell you the aisle width you need.
The actual working aisle also depends on:
Pallet dimensions
Pallet orientation
Fork length
Overall machine length
Machine width
Turning radius
Operator clearance
Rack layout
For buyers, the most useful number is therefore not simply “turning radius.”
It is:
“What aisle width does this exact stacker require with my actual pallet?”
1. Turning Radius and Aisle Width Are Not the Same
This is an important distinction when comparing electric pallet stackers.
Turning radius describes how tightly the machine can turn.
Working aisle width describes how much space is required for the machine and pallet to make the necessary maneuver.
A machine can have a small turning radius but still require a wider working aisle because the pallet and forks add length to the overall combination.
For example, one published 1.5-ton electric stacker has a turning radius of about 1,342 mm, while its listed aisle width with a 1,000 × 1,200 mm pallet is about 2,074 mm when the pallet is positioned across the forks.
That difference is exactly why warehouse buyers should not use turning radius as the only measurement.
2. A 2.0-Meter Aisle Is Not Automatically Enough
Suppose your warehouse has a 2,000 mm aisle.
You may think:
“The stacker has a 1,400 mm turning radius, so it should fit.”
Not necessarily.
The machine needs to maneuver the pallet, not just rotate its own chassis.
A published 1.5-ton electric stacker lists an aisle requirement of about 2,040 mm for an 800 × 1,200 mm pallet in one orientation and about 2,074 mm for a 1,000 × 1,200 mm pallet in another configuration.
That means a nominal 2,000 mm aisle could be too tight for that particular machine and pallet combination.
This is a good example of why the supplier should check the complete application before confirming the model.
3. Practical Example: 1,200 × 1,000 mm Pallet
Imagine a warehouse with:
Pallet size: 1,200 × 1,000 mm
Maximum load: 1,500 kg
Lift height: 3,000 mm
Aisle width: 2,400 mm
Indoor concrete floor
A 1.5-ton electric pallet stacker can be evaluated for this application.
One published 1.5-ton walkie stacker has:
Capacity: 1,500 kg
Fork length: 1,150 mm
Turning radius: 1,342 mm
Overall width: 795 mm
Aisle width with 1,000 × 1,200 mm pallet: approximately 2,074 mm in the listed configuration.
With a 2,400 mm aisle, there is more nominal working space than the listed 2,074 mm aisle requirement.
However, the final recommendation should still consider the rack clearance, pallet orientation, operator movement, and actual maneuvering path.
This is the type of information a buyer should request before placing an order.
4. What If the Warehouse Has Narrow Aisles?
Narrow warehouse aisles do not necessarily mean that you cannot use an electric pallet stacker.
It means the machine configuration needs to be selected more carefully.
For example, if your available aisle is approximately 2,300 mm, a compact walkie electric pallet stacker may be worth evaluating.
A published 2-ton electric pallet stacker lists aisle widths of approximately 2,307 mm for an 800 × 1,200 mm pallet and 2,377 mm for a 1,000 × 1,200 mm pallet. Its minimum turning radius is approximately 1,494 mm.
This gives buyers a useful reference point.
However, do not assume that every 2-ton stacker will have the same dimensions.
Two machines with the same:
2,000 kg capacity
can have different:
Wheelbase
Overall length
Fork length
Turning radius
Chassis width
Aisle requirement
Always check the actual model specification.
5. Fork Length Can Affect Warehouse Maneuverability
Fork length is another reason why two similar electric pallet stackers may require different working space.
A common fork length is around 1,150 mm.
If a customer requires a special longer fork, the total handling geometry can change.
For example:
Application A
Standard 1,200 × 1,000 mm pallet
1,150 mm forks
1.5-ton capacity
3,000 mm lift height
Application B
Oversized pallet
1,500 mm special forks
1.5-ton capacity
3,000 mm lift height
Although both machines may have the same rated capacity and lift height, they should not automatically be expected to have identical maneuvering requirements.
This is particularly important for warehouses with rack-to-rack aisles.
6. Walkie vs. Stand-On Electric Pallet Stackers
The operating configuration also affects the space requirements.
A walkie electric pallet stacker is controlled by the operator walking behind or beside the machine.
A stand-on model gives the operator a platform and is generally designed for applications involving more frequent travel.
Published specifications for stand-on electric pallet stackers show aisle requirements around 2.6–3.0 m for certain 1.5–2.0 ton configurations with 1,000 × 1,200 mm pallets, depending on whether the platform is folded or open.
This demonstrates an important purchasing point:
Do not compare a walkie stacker and stand-on stacker only by capacity.
The machine structure and operating configuration can affect the space required.
If your warehouse has very limited aisles, tell the supplier whether you need:
Walkie operation
Stand-on operation
Frequent long-distance travel
Occasional pallet positioning
The application can determine which design is more appropriate.
7. Check the Tightest Point in Your Warehouse
When measuring your warehouse, do not measure only the average aisle.
Find the tightest areas.
Typical problem locations include:
Rack ends
Warehouse corners
Loading areas
Doorways
Container entrances
Production-line entrances
Pallet staging zones
Narrow passages between racks
For example, your main warehouse aisles may be 2,500 mm wide, but a doorway may only be 2,100 mm.
The doorway could become the actual limiting dimension.
This is why we recommend sending a simple warehouse layout or photographs when requesting an electric pallet stacker quotation.
8. Example: Choosing a Stacker for a 2.5-Meter Aisle
Consider a customer who operates a distribution warehouse with:
Aisle width: 2,500 mm
Pallet: 1,200 × 1,000 mm
Maximum load: 1,500 kg
Lift height: 3,500 mm
Indoor application
High-frequency pallet movement
A 1.5-ton walkie electric pallet stacker is one configuration worth evaluating.
The supplier should check:
Turning radius
Working aisle width
Fork length
Mast height
Overall width
Residual capacity at 3,500 mm
Doorway clearance
A machine with a nominal 1,500 kg capacity is not enough information to approve the order.
The complete dimensions need to fit the customer's facility.
9. Give Your Supplier These Five Numbers
If you are a dealer, distributor, warehouse operator, or equipment buyer, you can make the quotation process much faster by providing five basic figures:
1. Maximum load:
For example, 1,500 kg
2. Pallet size:
For example, 1,200 × 1,000 mm
3. Required lift height:
For example, 3,500 mm
4. Narrowest aisle:
For example, 2,500 mm
5. Operation type:
Walkie or stand-on
With these five pieces of information, the supplier can start checking whether a specific electric pallet stacker configuration is suitable.
A warehouse drawing or pallet photograph is even better.
10. Don't Choose a Pallet Stacker From Capacity Alone
A common purchasing mistake is to compare:
1.5T vs. 2T
and choose the machine with the required capacity.
For warehouse applications, a better comparison is:
| Specification | Example |
|---|---|
| Rated capacity | 1,500 kg |
| Lift height | 3,500 mm |
| Fork length | 1,150 mm |
| Turning radius | 1,342–1,500 mm range depending on model |
| Pallet | 1,200 × 1,000 mm |
| Working aisle | Confirm for exact model |
| Operation | Walkie |
| Application | Warehouse / distribution |
The exact figures vary by model, so the final selection should be based on the manufacturer's technical drawing and the customer's actual warehouse layout. Published models demonstrate that even machines in the same capacity class can have different turning radii and aisle requirements.
