Right now the alarm sounds the whole time the forks are above free lift (raising or lowering or reaching). But a lot of time and thought was used to research the best way to warn other associates without driving the operator crazy.
The audible was mounted away from the operator. Five of the six sides of the audible was insulated in sound retardant material. This was very pleasing to the operators. We ran a demo on five units for a week (24/7), and received excellent reports from both the operators and co-workers.
I do agree with both of you, there will be some who will try to "modify" the system. But like all other parts of the lifts, this would be added to the daily check list. And of course the possibility of termination SHOULD deter the desire to "modify" somewhat.
What about the idea of using a photo cell on the load beams, that would illuminate a stop light, strobe or similar to warn associates? This would be without noise, and could be a alternative.
Thanks again for you input.
