Fulton Hogan is a major Australasian civil contractor with 50 depots and offices across Australia.
The electrical system at the Fulton Hogan asphalt plant in Toowoomba had reached the end of its 33 year lifespan and was unreliable, unpredictable and dangerous.
Fulton Hogan initially introduced administrative solutions to address the failing electrical system; however, electrical failures increased, which led to the elimination of the defunct wiring and the installation of new systems. Several safety features were also implemented including soft starter circuitry, a functional circuit breaker and touch screen controls on a programmable logic controller (PLC).
The PLC and input/output cards make up a touch screen user interface used for the automation of electromechanical processes, such as the control of machinery in the field and the monitoring of faults and issues. Operators now have a digital display indicating how each process works.
The solution has led to:
- a reduction in lost work hours due to outages (from 60 per month to almost zero)
- opening the MCC electrical cabinet from several times per day to not at all
- faster and less complicated training
- a more simplified process to produce asphalt.
