Abstract

system for monitoring a status of attachment of a ground engaging tool (GET) at a mining, earth moving or rock processing machine. The system comprises providing GET with at least one proximity sensor configured to sense a proximity of the GET relative to a mount region of heavy machinery to which the GET is mountable, the proximity sensor being provided at the electronic tag. The proximity sensor is configured to generate proximity data that is transmitted from the GET via a wireless communication pathway to a receiver located remote from the GET with the receiver configured to output in real-time the attachment status of the GET. The system further comprises an activator having a printed circuit board (PCB), a processor and a transceiver, the activator being configured for wireless communication with the electronic tag. The present system is advantageous to identify partial detachment or loosening of a GET so as to prevent undesirable GET loss and contamination of extracted or processed raw material.
