ABSTRACT:
An anti-collision protection system for machines that operate in a raw material stockpile yard is disclosed. The machines are moveable in the yard in defined paths, with each machine including a material delivery and/or material recovery boom that can be rotated about a vertical axis. The system includes a means for defining an envelope around each boom (5) that moves with the boom, with each envelope forming a boundary of an exclusion zone for the boom. The system also includes a means for detecting an intersection of the boundaries of the exclusion zones and a means responsive to a detected boundary intersection to prevent collision of the machines.
