When buying a 1.5 ton electric stacker, many buyers focus on the 1,500 kg capacity and lifting height but overlook one specification that directly affects daily operation: fork size.
The wrong fork length or fork spacing can make pallet handling difficult even when the stacker has enough lifting capacity.
For warehouse operators and equipment distributors, checking the relationship between electric stacker fork size and pallet dimensions before ordering can prevent problems with pallet entry, load support and storage operations.
A common 1.5 ton configuration uses forks around 1,150 mm long, while some market models offer approximately 1,070 or 1,150 mm fork lengths.
1. What Fork Size Should You Check?
When comparing a 1.5 ton electric stacker, do not look only at "fork length."
There are several important dimensions:
Fork length
Fork width
Fork thickness
Distance between forks
Overall fork outside width
Load center
For example, a representative 1.5T electric stacker configuration may use:
Fork length: 1,150 mm
Fork width: approximately 170–190 mm
Fork thickness: approximately 55–65 mm
Fork outside width: approximately 570–695 mm
Actual dimensions vary by stacker design and fork configuration. Publicly listed 1.5T models show examples including 60 × 170 × 1,150 mm and 65 × 190 × 1,150 mm fork dimensions.
This is why pallet compatibility should always be confirmed from the actual machine drawing or specification sheet before purchase.
2. Is a 1,150 mm Fork Suitable for Standard Pallets?
For many common pallet applications, 1,150 mm forks provide a practical balance between pallet support and machine dimensions.
For example, a warehouse may use:
800 × 1,200 mm pallets
1,000 × 1,200 mm pallets
Other customized industrial pallets
A 1,150 mm fork can enter many pallet configurations from the appropriate side, but compatibility depends on the pallet's entry openings and the direction in which the pallet is handled.
Therefore, pallet dimensions alone are not enough.
You should also confirm:
Which side will the forks enter?
3. 800 × 1,200 mm Pallets
The 800 × 1,200 mm pallet is a common format used in warehouse and logistics operations.
For example, if the pallet is 800 mm wide and 1,200 mm long, a buyer might assume that any 1,150 mm fork will automatically work.
That is not always correct.
The pallet design can include:
Two-way entry
Four-way entry
Open-bottom construction
Block construction
Different fork openings
Therefore, the stacker needs to be matched to the actual pallet structure.
Some 1.5T electric stacker specifications list aisle requirements based specifically on an 800 × 1,200 mm pallet, demonstrating that pallet size is directly related to machine maneuverability and warehouse layout.
4. 1,000 × 1,200 mm Pallets
For warehouses using 1,000 × 1,200 mm pallets, the larger pallet footprint provides a different handling requirement.
The buyer should confirm:
Fork entry direction
Fork length
Fork spacing
Load center
Required aisle width
Pallet construction
For example, some 1.5T stacker specifications list aisle widths of approximately 2,500–2,600 mm depending on the pallet orientation and machine configuration.
This is particularly important when the machine will operate in a narrow warehouse.
5. Fork Length: 1,070 mm vs. 1,150 mm
One of the most common questions from buyers is:
Should I choose 1,070 mm or 1,150 mm forks?
The answer depends on the pallet and load.
1,070 mm Forks
These can be suitable when:
Loads are relatively compact
Warehouse space is limited
The pallet design matches the fork length
Shorter forks are preferred for maneuverability
1,150 mm Forks
These are commonly selected when:
Handling standard warehouse pallets
Supporting longer loads
Working with common 1,200 mm pallet dimensions
More fork engagement is required
Several commercially available 1.5T stackers list 1,070/1,150 mm fork options.
For a distributor selling to multiple markets, offering a practical 1,150 mm configuration can cover many common pallet-handling applications.
6. Fork Spacing Is Just as Important as Fork Length
Fork length gets most of the attention, but fork spacing can determine whether the forks can actually enter the pallet openings correctly.
For example, a pallet may have:
Narrow central openings
Wide openings
Reinforced blocks
Bottom boards
Cross beams
If the fork spacing does not match the pallet structure, the machine may not be able to position both forks correctly.
A typical adjustable fork configuration may provide different fork outside widths. Some 1.5T electric stacker specifications list overall fork widths around 570 mm and 695 mm.
For custom pallets, buyers should send a pallet drawing or photos to the supplier before ordering.
7. Load Center: The Specification Buyers Should Not Ignore
Another important specification is the load center.
A 1.5 ton stacker does not simply mean that every 1,500 kg load can be placed anywhere on the forks.
The rated capacity is normally associated with a specified load center.
For example, published 1.5T stacker specifications show load centers such as 500 mm or 600 mm, depending on the machine design.
Example
Imagine a 1,500 kg pallet.
If its center of gravity is approximately 500 mm from the fork face, the machine's rated capacity may apply under the specified conditions.
But if the load is significantly longer and its center of gravity moves farther forward, the effective load condition changes.
This is why buyers should provide both:
Pallet size + pallet weight
rather than simply saying:
"We need a 1.5 ton stacker."
8. Example: Choosing a Stacker for an 800 × 1,200 mm Pallet
Suppose a customer operates a warehouse with:
Pallet size: 800 × 1,200 mm
Maximum pallet weight: 1,000 kg
Required lifting height: 3,000 mm
Indoor operation
Narrow warehouse aisles
Frequent pallet stacking
A practical configuration could be a:
1,500 kg electric stacker
3,000 mm lifting height
1,150 mm forks
The 1,500 kg rated capacity gives a capacity margin above the customer's 1,000 kg normal load, while the 3,000 mm mast provides the required vertical storage height.
The final selection should still be confirmed against the manufacturer's rated-capacity chart, load center and actual pallet entry direction.
9. Example: Heavy 1,200 kg Pallets
Now consider a different customer:
Pallet size: 1,000 × 1,200 mm
Pallet weight: 1,200 kg
Lifting height: 3,500 mm
Load center: approximately 500 mm
Daily operation: frequent pallet stacking
This buyer should not simply select a machine based on the 1,500 kg headline capacity.
The supplier should confirm the rated capacity at the required lifting height and load center.
This is especially important because the working capacity of a stacker can depend on the specific configuration.
10. Pallet Compatibility Checklist Before Ordering
Before purchasing a pallet stacker for sale, ask the customer for these six pieces of information:
| Item | Example |
|---|---|
| Pallet length | 1,200 mm |
| Pallet width | 800 mm |
| Maximum load | 1,000 kg |
| Fork entry | 800 mm side |
| Required lifting height | 3,000 mm |
| Load center | 500 mm |
With these numbers, the supplier can recommend the appropriate fork and mast configuration much more accurately.
11. Common Pallet Applications for a 1.5 Ton Electric Stacker
A 1.5 ton electric stacker can be used for many commercial and industrial pallet-handling applications, including:
Warehouses
Moving finished products between storage and picking areas.
Manufacturing Plants
Transporting raw materials and finished goods.
Logistics Centers
Moving palletized shipments between staging and storage areas.
Retail Distribution
Handling packaged products in backroom and distribution operations.
Workshops
Moving heavy components and materials between production areas.
The important point is that the stacker should be configured around the customer's actual pallet and warehouse conditions.
12. Don't Choose Fork Size From Pallet Size Alone
A pallet measuring 800 × 1,200 mm does not automatically tell you which fork configuration is correct.
You also need to know:
Pallet entry direction
Pallet opening dimensions
Bottom-board arrangement
Load weight
Load center
Fork spacing
Required lifting height
Aisle width
This information can turn a general equipment inquiry into a precise machine quotation.
13. Why 1,150 mm Forks Are a Practical Choice for Many Buyers
For many warehouse applications, 1,150 mm forks provide a useful working length for standard palletized loads.
They can be paired with different lifting-height configurations, allowing the same basic 1.5 ton electric stacker platform to serve different warehouse requirements.
For example:
1,150 mm forks + 2,500 mm mast
For lower pallet storage.
1,150 mm forks + 3,000 mm mast
For general warehouse stacking.
1,150 mm forks + 3,500 mm mast
For medium-height storage.
1,150 mm forks + 4,500–5,000 mm mast
For higher pallet rack applications.
This approach is also useful for distributors because the product can be configured according to different customer requirements rather than selling one fixed specification.
14. Choose the Right 1.5 Ton Electric Stacker for Your Pallets
When purchasing a 1.5 ton electric stacker, fork size and pallet compatibility should be confirmed before discussing the final machine configuration.
A suitable specification may include:
1,500 kg rated capacity
500 mm load center
1,150 mm fork length
Adjustable fork spacing
Multiple lifting-height options
Electric travel and lifting
Configuration for indoor warehouse applications
The exact fork dimensions and capacity should be confirmed according to the selected model.
