The system has been running in the two test periods. The first trial run showed problems with severe fogging in the premises that disturbed the camera images and even problems with many false alarms due to inadequate tuning. The second measurement period worked much better, but the measurement of the thickness of the brake blocks still had problems. Additional tests with alternative technologies showed improvement.
The system has been equipped with Internet site and remote end reports as UH staff in Malmberget get detailed info about the carts that are on their way north. Their inspection could with the system in operation could be streamlined, particularly in winter. Despite the above limitations in the measurement quality of the prototype system, there has been positive response from LKAB's maintenance staff.
The system became dormant before new decisions at LKAB in the autumn of 2015, but because of the economic situation and the low price of ore, LKAB decided to close down the project and to dismantle the equipment mothballed.
