A recent site visit to the Burpengary Wastewater Treatment Plant to inspect existing clarifiers revealed that they required upgrading in order to meet current Health & Safety standards. All clarifier bridges are required to have obstruction sensing devices installed in front of the bridge access ladders and the leading wheel on each wheeled support carriage. This is to prevent bodily injury being inflicted should the machine unexpectedly contact an unaware observer.
The EPCO solution was to provide four ladder sensor (plough) assemblies complete with a stainless steel spring, stainless steel assembly bolting & Omron micro switch and actuator.
There were also four leading wheel track wiper assemblies supplied (one per leading wheel) each manufactured from stainless steel with stainless steel assembly bolting, neoprene wiper blade & Omron micro switch and actuator.
These were able to be retrofitted to the existing equipment and provided an efficient, cost effective solution.
