Abstract
A safe-zone sensing system for a lift having a base, a lift platform, and a driving system for raising and lowering the lift platform. The safe-zone sensing system includes a sensor system having a plurality of sensors mounted to the base of the lift. The sensors collectively defining a safe-zone around the base of the lift and detecting motion or obstructions within the safe zone, a controller fires the sensors in a preselected sequence for continuously scanning the safe zone. Scanning is started when the platform raises above a preselected height. The sensor controller generates an alert which initiates a safety sequence when motion or obstructions are sensed by at least one of the plurality of sensors.
