Abstract
Systems and methods for detecting attachment of a lanyard at a utility platform of an aerial device are described. In some embodiments, a lanyard attachment device is disposed on a utility platform. The lanyard attachment device may comprise a sensor detecting when a lanyard is attached to the lanyard attachment device. In some embodiments, the utility platform is separated from a base of the aerial device by a dielectric gap, and a light signal is indicative of the state of the lanyard attachment device. Furthermore, anti-tie-down functionality may be used to detect error or tampering of the lanyard attachment device.
