Devices are available to help eliminate blind spots and associated accidents involving large off-highway mining equipment. Camera systems and, more recently, radar and RFID systems designed specifically for heavy equipment, are now on the market. Successful implementation of these systems can be achieved if their shortcomings are realized and anticipated. Cameras can benefit from the addition of a sensor system, so that the equipment operator is prompted to check the video monitor while moving the equipment. Radar is good at detecting people and small vehicles, but it is susceptible to nuisance alarms, requiring cameras to verify the cause and exact location of the nearby object. RFID, while more expensive than other solutions, is very reliable, and its increased functionality and integrated camera system make it an attractive long-term solution. No collision warning system can replace the training and caution necessary for operating heavy equipment. However, technology can aid in reducing some of the guesswork required when operating equipment that has extensive blind spots.
