Success.Yes, it was a little "too free", but I found the problem and proved it.A little trial and error would make it perfect. Instead of drawing 25-28 Amps going up, it was 15-18 Amps.Going down 2-7 amps, instead of 13-15 Amps. Almost non stop.Torturing it pretty hard, zero problems with the gear box.Īt some point, a bearing in the drive failed, from the abuse.This was heat related, they never fail in the field.While it is apart for repair, I change one dimension on the rack and pinion drive mechanism.Moved the pinion away from the rack by. Had it running 3 minutes ON, 30 seconds OFF. Add a fan, and a larger battery charger.Because the motor was rated for "intermittent use", 3 minutes on, 10 minutes off, it ran HOT.Get a bigger fan.

A lady in the lane next to me couldn't wait her turn to give her order to the order taker in her lane. There is usually one order taker for each lane.
