Safety should be evaluated as a complete system rather than by counting sensors on an autonomous forklift. A vehicle may have LiDAR, cameras, emergency-stop buttons, warning lights, and other safety components, but the buyer still needs to verify how those components interact during real operating conditions.
For an overseas warehouse, the most useful approach is to define safety functions, test conditions, and expected responses before purchasing the fleet.
Start by asking what the vehicle is designed to do when a person, obstacle, vehicle, or abnormal condition enters its operating area.
The safety review should cover detection, warning, controlled stopping, emergency stopping, restart behavior, fault detection, and recovery.
Ask which scanner or protective sensing devices are installed and what role each one performs.
A buyer should understand the protective field, warning field, mounting position, response behavior, and integration with the vehicle's safety control system.
A scanner model number alone does not prove that the complete safety function is correctly implemented.
Physical emergency-stop buttons should be tested under representative operating conditions.
The test should record the vehicle speed, payload, floor condition, direction of travel, stopping behavior, and reset procedure.
Emergency-stop response time and stopping distance are different measurements and should not be treated as the same requirement.
If the project uses a wireless emergency-stop device or remote safety function, test the actual communication environment.
Test range, interference, signal loss, communication recovery, and the vehicle's behavior when the wireless connection is interrupted.
Ordinary wireless communication should not automatically be treated as a safety-rated emergency-stop channel.
Use representative pedestrian approach directions and warehouse traffic conditions.
The test should include people entering the vehicle's path from different directions, people approaching from the side, and obstacles that partially block the sensing area.
The exact detection and stopping behavior should be documented rather than described only as “360-degree safety.”
Vehicle behavior can change with payload.
Safety testing should therefore consider both unloaded and representative loaded conditions, especially when braking distance, stability, or lifting operations are involved.
High-lift autonomous forklifts require additional attention around rack clearance, load stability, mast movement, fork positioning, and elevated loads.
Testing should include representative rack levels and payload conditions rather than only floor-level travel.
Safety performance includes what happens after a fault occurs.
Test scenarios such as sensor faults, communication loss, blocked routes, low battery, manual intervention, and system restart.
The system should have a defined procedure for returning to normal operation rather than allowing an unexpected automatic restart.
Ask the supplier to explain how safety scanners, emergency stops, safety controllers, drive control, hydraulic functions, warning devices, and fleet software interact.
The purpose is to understand which functions are safety-related and which are ordinary operational controls.
Depending on the project, request applicable standards information, risk-assessment documentation, safety-related control documentation, electrical schematics, scanner specifications, emergency-stop information, test records, and operating manuals.
The exact documentation should correspond to the purchased vehicle and the destination site's requirements.
Safety should not be tested only during the supplier's internal demonstration.
The agreed FAT and SAT procedures should contain measurable safety tests and documented results.
Site acceptance should consider the actual warehouse environment, because racks, walls, pedestrians, floor conditions, traffic patterns, and local equipment can change the real operating environment.
For overseas buyers, safety verification should therefore combine the vehicle's technical documentation, the supplier's safety architecture, controlled FAT testing, and site-specific validation rather than relying on a marketing statement or a sensor list.
