A fall arresting/prevention safety protection device for aerial lifts that delivers notifications and warnings to individuals who are subject to accidental falls or other safety hazards when performing construction or the like or when operating elevating construction machinery such as aerial lift work platforms, bucket trucks and similar type elevating work platforms. The invention further provides a load sensor that when activated transmits an emergency signal to operators, supervisors and emergency personnel. The present invention further provides a remote control to access and control movement of the aerial lift through a wireless transmission in the event the lift operator falls out of or is ejected from the bucket or work platform.
