In a busy manufacturing facility, people, forklifts, and materials are constantly moving.
Introduce an autonomous mobile robot (AMR) forklift into that environment, and one question becomes especially important:
A SESTO Magnus Forklift MF1400PS, capable of handling payloads up to 1,400 kg, approaches a shared factory crossing. What should happen next?
The answer goes beyond whether the AMR can detect a person and stop in time. It depends on how the entire operating environment has been planned, from pedestrian movement and vehicle routes to crossings and material flow.
Safe AMR deployment starts with system and workflow design, not with a single sensor or warning device.
Before deploying an AMR forklift, look at how people already move around the factory.
🚶 Where are the busiest pedestrian walkways?
🏗️ Where do manual forklifts travel?
⚠️ Where are the blind corners?
🚪 Where do operators frequently enter and leave production areas?
These are potential interaction points that should be identified before AMR routes are finalised.
The shortest route from Point A to Point B may not always be the most suitable route when people and other equipment are sharing the same space.
2. Manage Speed Around Shared Areas
An AMR forklift does not necessarily need to travel at the same speed throughout its entire route.
Busy pedestrian crossings, intersections, production entrances, and blind corners may require different operating considerations from an open material-handling aisle.
Creating appropriate operating zones can help make AMR movement around these areas more controlled and predictable.
The goal isn’t simply maximum speed. It’s predictable material movement.
3. Make the Crossing Obvious
Workers should be able to recognise where AMR forklifts are likely to travel.
Clearly defined pedestrian crossings, AMR routes, floor markings, and designated operating areas can help reduce unexpected interactions between workers and autonomous equipment.
Instead of relying entirely on workers noticing an approaching vehicle, the environment itself should help communicate:
People cross here. AMRs travel here. Pay attention here.
However, floor markings and designated crossings are only part of the overall safety approach. Safety measures should be determined through a site-specific risk assessment based on how people, vehicles, AMRs, and materials actually move through the facility.
4. Consider Visibility and Warning Signals
Blind corners and obstructed intersections deserve additional attention.
Depending on the application, site requirements, and risk assessment, visual indicators, audible warnings, and other signalling measures can help communicate that an AMR forklift is approaching.
Manufacturers should also consider whether racks, machinery, pallets, or other equipment are restricting visibility around important crossings.
Sometimes improving safety isn’t about adding more technology to the AMR.
It can also involve improving the operating environment around it.
Importantly, no individual sensor, warning light, floor marking, or other measure should be treated as sufficient on its own.
Safety measures must be determined through a site-specific risk assessment, taking into account the AMR, its payload, pedestrian movement, other vehicles, crossings, visibility, and the surrounding operating environment.
5. Think About the Load Too
When discussing crossing safety, don’t look only at the AMR forklift.
Look at what it is carrying.
A loaded pallet can affect the overall operating environment, including visibility, manoeuvring requirements, and the space occupied by the complete moving system.
Manufacturers should therefore evaluate the AMR forklift + load + route + surrounding traffic together rather than treating each element separately.
6. One Safe Crossing Isn’t Enough
A manufacturing facility may have many interaction points.
An AMR forklift could travel from a warehouse through a production area, pass several pedestrian crossings and intersections, collect another pallet, and return through a different route.
As more autonomous vehicles are introduced, manufacturers need to consider how these movements work together across the entire facility.
This shifts the question from:
“Can the AMR forklift safely cross here?”
to:
“How do we design material flow so people, AMR forklifts, and existing equipment can operate predictably together?”
Where the SESTO MF1400PS Fits In
For manufacturers looking to automate pallet movement, the SESTO MF1400PS is a compact autonomous forklift stacker designed for material handling in confined environments.
With its compact 1,710 × 989 mm footprint, the MF1400PS has a payload capacity of up to 1,400 kg and is designed for autonomous pallet handling in manufacturing and warehouse environments.
But the AMR forklift is only one part of the deployment.
When integrating the MF1400PS into an existing facility, its routes should be considered together with pedestrian crossings, manual forklift traffic, production entrances, pickup and drop-off locations, and other shared areas.
The objective is not simply to introduce an autonomous forklift.
It is to integrate autonomous material movement into the existing workflow safely and predictably.
Start With the Workflow
Safe AMR forklift deployment is not achieved by relying on a single sensor, warning light, floor marking, or piece of equipment.
It requires manufacturers to look at the complete operating environment, which includes pedestrian movement, vehicle routes, crossings, visibility, traffic patterns, payloads, and material flow.
Safety measures should be determined through a site-specific risk assessment, with applicable safety requirements and standards considered as part of the overall system design.
Safe AMR deployment starts with system and workflow design and not with a single sensor or warning device.
