A speed limiter slows a forklift near pedestrians only if it is linked to a detection system, such as UWB tags worn by people or cameras that recognize them, and to the truck's speed controls. A fixed limiter caps top speed everywhere and does not respond to people, and a radar speed sign only displays speed to the driver. Detection-linked limiters apply a lower limit, often in stages, when a person is inside a set distance, and work only on compatible forklifts with a CAN-bus or speed-control interface. Many are sold as part of a wider collision avoidance platform rather than as a standalone limiter.
The full guide is forklift speed limiters, explained, and the speed control buyer’s guide compares governor types. Suppliers that offer pedestrian-triggered slowdown are grouped by capability in what collision avoidance means and listed in the vendor directory. The vendors compared guide lists suppliers by technology, and the provider vetting guide sets out the questions to ask.
When comparing, ask which of your truck models each supplier can integrate, whether the manufacturer approves the modification under 29 CFR 1910.178(a)(4), how deceleration is controlled with a raised load, and what the truck does if the detection system fails. Pilot it on your busiest route before fleet rollout.
