hihi all ^_^
long story short, my dad was asking me if I knew any thing about Proximity Sensors and stuff. I had no idea but I figured I would ask here ^_^
basickly he needs a Proximity Sensor, that can be used outdoors, and it needs to be wireless.
the reason he needs it is for a crane, basickly the crane for what ever brillent reason, does not have a sensor on it to stop who ever is in the cabin form constily pulling the hook up. so the cables to pull the hook up tend to break. worse, the dumb cabin can not see past the one direction, so if something needs to be lifted form said direction, its impossible to see the hook. (yes its a terrible crane, its not his or his companys).
anywho, what he needs is some kinda Proximity Sensor that would make it so it could sense when the hook/box gets close to the top of the boon where the cable goes in. so who ever operates it would get an alarm saying its to close.
does any one know of such a device or have an idea I could tell him? would be very helpful. thank you all ^_^
