This thing is more than meets the eye... Kelly, you'd appreciate this.. its run off a plc and can be run by remote control when in the loading unloading area. It has sound and collision avoidance system. Pretty high tech! Most of the system I'll have to strip out to get it running again. I pulled the motor and dropped the battery pack out from underneath it today to assess their condition before I go to far into this thing. Might be better off converting to gas as having to replace all 24 batteries could put a man in the poor house.
