Abstract

A system and method for monitoring a lifting device is disclosed. The method receives location information from a position determiner module coupled with a point of interest associated with the lifting device and determines an autonomous position of the point of interest based on the location information. The method further includes accessing position information associated with a jobsite object and monitoring the lifting device based on the autonomous position of the point of interest and based on the position information of the jobsite object to prevent collision.
