A method of alerting a person to the proximity of a load being carried by a crane includes generating a trigger signal from a crane operator station when a load being carried by a crane is in proximity to a person. A wireless alarm signal is transmitted from a transmitter in response to the trigger signal. The wireless alarm signal is received by a receiver in wireless communication with the transmitter. An alarm from an alarm device is created in response to receiving the wireless alarm signal by the receiver. The alarm device is suspended from a load line that carries the load to be in proximity with the load.
