Forklift impact sensors use an accelerometer mounted on the truck to measure sudden changes in motion. When a shock exceeds a set threshold, the unit records the time, the truck, the logged-in operator and, with location tracking, the place. Depending on configuration, it can alert a supervisor by text, email or app, and on compatible forklifts it can drop the truck to a slow speed or lock it out until a supervisor resets it. Thresholds are set per truck type and floor condition so that normal bumps over dock plates and joints do not count as impacts.
The full guide is forklift fleet management and telemetry. Impact data pays off in aggregate: repeated hits at the same rack bay, door or corner point to a layout or visibility problem, while repeated hits by one operator point to coaching. Calibrate thresholds during the first weeks of use, since thresholds set too low generate noise and thresholds set too high miss real damage. Pair impact logs with racking inspection so struck uprights get checked. Impact sensors record collisions after they happen; they do not detect pedestrians or prevent contact.
