A warehouse floor may look smooth enough for manual forklifts, but that does not automatically mean it is suitable for an automated forklift operating repeatedly along fixed routes or placing pallets at high rack levels.

Floor conditions can affect vehicle stability, localization, braking, steering, lifting performance, and pallet placement. For overseas buyers planning an AGV project, checking the floor before equipment selection can help identify engineering risks before they become commissioning problems.

Why Floor Conditions Matter

Manual forklift drivers can often compensate for minor floor irregularities through steering and driving adjustments. An AGV follows configured motion and positioning rules. Repeated floor variations may therefore affect its operating consistency.

The impact depends on the vehicle type, wheel configuration, travel speed, payload, lift height, route, and required positioning performance.

Check Floor Flatness and Levelness

Flatness describes local surface variation, while levelness relates to the overall slope of the floor. Both may matter, but they affect AGV operation in different ways.

For high-lift forklifts, floor variation can influence mast behavior and the accuracy of pallet placement. For narrow-aisle vehicles, floor conditions along the travel path may also affect repeated alignment.

Ask the AGV supplier to specify the floor measurement method and acceptance criteria for the proposed vehicle and operating conditions. Avoid applying one universal tolerance to every AGV project.

Inspect Joints, Cracks, and Local Transitions

Pay particular attention to:

• Concrete expansion joints

• Floor cracks and repaired areas

• Changes between concrete and epoxy surfaces

• Dock transitions

• Drainage channels

• Uneven patches near rack rows

• Thresholds between warehouse zones

A small transition may be manageable for one vehicle but problematic for another, especially when the vehicle carries a high or sensitive load.

Check Floor Load Capacity

Floor capacity should be reviewed using the actual vehicle and load data, not only the AGV's rated payload.

The relevant information may include vehicle weight, axle loads, wheel arrangement, load distribution, and operating conditions. For heavy-duty AGVs, the building's structural engineer may need to review the floor design.

Evaluate Surface Conditions

Surface material and condition can influence traction, wheel wear, and braking behavior.

Check for:

• Loose dust and debris

• Oil or chemical contamination

• Water accumulation

• Polished or slippery areas

• Damaged epoxy coatings

• Loose floor coverings

Where the floor is frequently wet or contaminated, the supplier should evaluate the actual operating condition rather than relying only on a dry-floor demonstration.

Map the Critical Routes

It is not always necessary to inspect every square meter with the same level of detail. Start with the routes that have the greatest operational impact.

These may include narrow aisles, high-lift storage areas, charging locations, dock approaches, and frequently used intersections.

Record the location of defects on a warehouse drawing or digital floor plan so the supplier can review them against the proposed AGV routes.

Request a Project-Specific Floor Assessment

Before finalizing the vehicle specification, provide the supplier with floor survey information and ask which conditions could affect the proposed operation.

The review should identify whether floor repairs, route restrictions, speed adjustments, or additional testing are required.

Include Floor Conditions in Acceptance Testing

FAT and SAT should use representative floor conditions wherever practical. Test loaded travel, braking, turning, pickup, and placement on the routes that matter to the project.

If the warehouse has known floor defects, document how they will be handled rather than leaving them as an informal commissioning assumption.

A floor assessment is most useful when it connects measured conditions to the actual AGV model, load, lift height, and warehouse route.
