Can you hear me now?



IMCO recently landed another project with Boeing; this time around it’s a job inside a building. We all know the dangers of using emission producing vehicles/equipment inside an enclosed environment. So management decided to obtain 3 "gently" used Cushman electric carts. We took extra caution not to cause any shorts because of the nearly 60volts running the motor. Not too complex in design except the one with the Curtis electronic motor controller. The controller is programed to make the electric motor behave like a combustion engine powered vehicle. A tech can hook up a programmer and change the drive-ability parameters of the cart. We didn't have a programmer so we had a little trouble with it. With the help of the magical internet and some manuals we found there, we had these voltage juiced up battery beasts running around in no time. One concern that I addressed though was that these things were incredibly quiet, too quiet. A man striding through a warehouse would cause way more noise than these Cushmans. There is a backup alarm on every single one, but going forward? This is not new technology for use where emissions are prohibited but I’m curios to know how many accidents occurred simply because you can’t hear these things put-put, or should I say zip along. Some people reference comically to equipping electric vehicles to imitate motor sounds, but I see somebody getting rich. Can you hear me now?

  1. Hi Alex,

    You're too slow. http://en.wikipedia.org/wiki/Electric_vehicle_warning_sounds

    Good thought though. (;
