Standard pallets make automated forklift deployment relatively straightforward. The challenge begins when a warehouse uses plastic pallets, custom wooden pallets, steel skids or wire mesh containers with different bottom structures.

For a Chinese AMR forklift, the critical issue is not simply whether the forks can physically enter the pallet. The vehicle must also determine where the load is located, whether the fork entry is safe, whether the load is properly supported and whether the configured fork position matches the actual pallet design.

Before importing an AMR forklift for non-standard pallet handling, buyers should therefore evaluate the vehicle's mechanical dimensions, sensing technology, fork positioning accuracy and software configuration capabilities.

Can a Chinese AMR Forklift Handle Plastic Pallets With Non-Standard Bottom Runners?

Potentially, but compatibility depends on the pallet's actual geometry.

Plastic pallets can have runner configurations that differ substantially from conventional wooden pallets. Some have three longitudinal runners, while others use multiple support feet or complex molded structures.

An automated forklift needs sufficient clearance for the forks to enter without contacting the pallet structure.

Important dimensions to verify include:

• Overall pallet length and width

• Fork entry height

• Runner height

• Runner spacing

• Bottom clearance

• Fork pocket dimensions

• Maximum pallet deformation

• Maximum load weight

• Load center position

A pallet that can be handled by a manual forklift may still require additional validation for an autonomous forklift because the AMR must repeat the same insertion movement without an operator visually correcting the fork position.

Why Bottom-Rail Geometry Matters

Consider two pallets with identical external dimensions.

The first pallet may have large open fork pockets.

The second may have narrow openings created by closely spaced bottom runners.

Both pallets may be described as the same nominal size, but their automation compatibility can be completely different.

For this reason, a Chinese AMR supplier should evaluate the actual pallet drawing or physical sample rather than relying only on the pallet's nominal dimensions.

How Does the Optical Sensor System Align With a Customized Steel Skid?

Steel transport skids create a different challenge because their surfaces, edges and reflectivity can differ considerably from conventional wooden pallets.

Depending on the AMR design, sensors may be used to determine:

• Pallet or skid position

• Fork-entry alignment

• Load presence

• Distance to the load

• Fork position

• Obstacle location

• Whether the vehicle has reached the expected pickup position

However, sensor performance should not be judged simply by asking whether the vehicle has “vision.”

The important question is:

Which sensor performs which function?

A fleet may use a combination of laser scanners, cameras, fork-position sensors and other proximity or safety sensors.

For a custom steel skid, the supplier should demonstrate the complete pickup process under realistic warehouse conditions.

Test the Actual Skid

Ideally, provide the Chinese manufacturer with:

CAD drawing → dimensional specification → photographs → load information → physical sample

This gives the engineering team enough information to determine whether mechanical or software modifications are necessary.

Does a Chinese AMR Forklift Use Hydraulic Clamping for Wire Mesh Containers?

This depends on the vehicle configuration.

A conventional autonomous forklift normally relies on correctly positioned forks to support a pallet or container. A wire mesh container may require a different attachment mechanism if the container cannot be safely supported by standard forks.

If a project requires hydraulic clamping, the engineering team should define the operating parameters rather than simply adding a hydraulic actuator.

Important parameters include:

• Maximum container weight

• Container dimensions

• Center of gravity

• Required clamping force

• Minimum and maximum clamping stroke

• Hydraulic pressure range

• Clamp opening width

• Required positioning accuracy

• Emergency release behavior

The control system should also prevent excessive force from being applied to lightweight or deformable containers.

Why Clamping Pressure Matters

A wire mesh container can behave very differently from a rigid pallet.

Too little clamping force can allow the container to move.

Too much force can deform the container or damage its contents.

Therefore, the required pressure should be determined through engineering validation rather than using one universal setting for every load type.

Can I Program Different Fork-Insertion Profiles for Different Pallets?

This is one of the most useful capabilities to investigate when purchasing an autonomous forklift for mixed pallet environments.

Different pallet types may require different:

• Approach speeds

• Stopping positions

• Fork heights

• Fork spacing

• Insertion depths

• Acceleration profiles

• Final positioning tolerances

A sophisticated fleet-management or vehicle-control system may allow these parameters to be associated with specific tasks, stations, pallet types or operating zones.

However, buyers should distinguish between user-configurable parameters and settings that require manufacturer engineering access.

If every modification requires the Chinese factory to remotely change the vehicle software, daily operational flexibility may be limited.

What Information Should I Give a Chinese AMR Manufacturer?

For non-standard pallets, the quality of the technical information provided during the RFQ can directly affect the accuracy of the proposed AGV configuration.

Prepare a pallet specification package containing:

Pallet Dimensions

• Length

• Width

• Overall height

• Bottom clearance

• Runner dimensions

• Runner spacing

• Fork-entry dimensions

Load Information

• Minimum load

• Maximum load

• Typical load

• Load center

• Load distribution

• Whether loads can overhang the pallet

Material Information

• Wood

• Plastic

• Steel

• Wire mesh

• Composite materials

Operating Conditions

• Indoor or outdoor operation

• Floor type

• Floor flatness

• Lighting conditions

• Dust or moisture exposure

• Rack or staging configuration

This information allows the Chinese engineering team to evaluate both the vehicle and the warehouse environment.

What Happens If a Pallet Is Slightly Misaligned?

A manual forklift operator can visually correct the fork position while entering a pallet.

An autonomous forklift needs another mechanism.

Depending on the system design, the vehicle may use sensors and localization information to detect the pallet or target position and make controlled corrections.

If the alignment falls outside the configured tolerance, the vehicle may stop rather than force the forks into the pallet.

This is an important point when evaluating an AMR:

The goal is not simply to make the vehicle pick up a pallet. The goal is to make it recognize when a pallet cannot be safely picked up.

That distinction becomes particularly important with damaged pallets, irregular runners and partially obstructed fork pockets.

How Should Non-Standard Pallets Be Tested Before Mass Deployment?

A factory acceptance test should include representative pallet types instead of testing only one standard pallet.

For example:

Testing should be performed with the actual pallet designs expected at the customer's warehouse.

A successful single pickup does not necessarily demonstrate reliable automation.

For B2B deployment, the more meaningful metric is the successful pickup rate over repeated cycles.

What Should I Include in the Chinese AGV RFQ?

If your warehouse uses non-standard industrial pallets, add explicit technical requirements to the RFQ.

Ask the manufacturer to confirm:

1. Compatible pallet dimensions

2. Minimum fork-entry clearance

3. Maximum pallet weight

4. Maximum load center

5. Fork positioning accuracy

6. Fork spacing adjustment range

7. Available pallet-detection sensors

8. Supported pallet-recognition methods

9. Configurable insertion speed

10. Configurable fork height

11. Configurable insertion depth

12. Handling procedure for misaligned pallets

13. Handling procedure for damaged pallets

14. Whether parameters can be changed locally

15. Whether custom pallet profiles can be stored in the software

16. Whether the supplier will test customer pallets before production

For a customized AMR forklift, these requirements should be agreed upon before manufacturing begins, not after the vehicles arrive at the warehouse.

Use Your Actual Pallet Geometry as the Starting Point

The biggest mistake when automating non-standard pallets is selecting an AMR based only on payload capacity and lifting height.

A 1.5-ton autonomous forklift may have more than enough lifting capacity but still be unsuitable if its fork dimensions, entry clearance or sensing configuration does not match the customer's pallets.

The better approach is to start with the actual pallet and load:

Pallet geometry → Load characteristics → Fork configuration → Sensor requirements → Software parameters → Repeated pickup testing

This gives the Chinese manufacturer a clear engineering target and gives the warehouse buyer measurable acceptance criteria before the fleet is shipped.
