"We also installed structural monitoring systems (SMS) made up of sensors on each dragline's boom, A-frame and mast, and on-board alarms," said Nick. "The alarms sound each time excessive strain is placed on the machine.
"The SMS records and displays how the dragline is being used, allowing us to pinpoint exactly which operator practices cause the highest damage. This was information we had never had access to before," he said.
The data enabled RTCA to create scorecards for each operator, through which they can track their performance, including "wear and tear" damage on the draglines. These scorecards are a first for our industry, and RTCA was able to use them to build a development programme for its operators.
Supervisors can now understand how each person operates a dragline, and where they need to focus to reduce damage to the equipment. The scorecards also help the operators reduce wear and tear, while maintaining their productivity targets.
The live feedback on board the dragline and the monthly scorecard summary has created a culture of improvement across the fleet. RTCA is now using the scorecards to validate individual performance reviews.
