RAISING THE BAR 3 Plant person interface Issued July 2012 Revised January 2015 Pedestrian and driver combined warning systems Ref System Trial by Summary Positives e The system is very robust The transponders are sealed units and not affected by weather The antennae unit is very durable e Larger machines can have more antennae added to give very full coverage of the machine or you can concentrate coverage for a specific area such as the counterweight of the machine e The plant operator can temporarily silence the alarm but has to continually hold a button to continually silence the alarm This prevents him from operating the plant machinery at the same time so making pedestrian access to the plant machinery for communication or slinging loads safe e A Plant is seriously considering fitting this to all machines excavators and dumpers that Costain hire and then selling the transponders as consumables A lot cheaper than buying the units e The Transponders work for all Sender units so any surviving the end of the contract can be used elsewhere Also the same transponder will alarm any number of sender units the holder approaches e Drivers are issued with a transponder thus making two machines capable of seeing each other and thus avoid two machines colliding The system is also designed in such a way that the driver s transponder will not trigger the alarm while in Walters at Costain the machine Ongrade Port Talb
