Forklift collision avoidance systems differ more by method than by brand, so compare companies on what their systems do. The main types are camera AI that detects people without tags, ultra-wideband (UWB) or RFID tag systems that work without line of sight, radar and LiDAR that detect any obstacle, and fixed intersection systems. Check whether a system combines warning with automatic slowdown on compatible forklifts, covers electric and internal-combustion trucks of mixed brands, and logs every event for review. Avoidance in the strict sense, where the truck acts, needs a speed-control interface; many products only warn.
The full comparison is Forklift collision avoidance systems compared. Suppliers are also listed in the vendor directory, and Forklift safety system vendors compared explains how they were assessed.
Ask each company which truck models support automatic slowdown, what retrofit work is needed, how it handles forklift-to-forklift as well as forklift-to-pedestrian approaches, and what false alert rate it recorded at a comparable site. A system reduces collision risk; it does not remove the need for separated walkways, training and the operating rules in OSHA 1910.178.
