Really,....hmmm..... I thought their was feet per minute because of safety. Too fast encourages un-safe work habits. It breaks down the system. People on the belt can't properly do their jobs. Splitting, spa, loading. It also breaks down production. Blow bys, poor load quality, pkgs not being tapped up, mis-loads, end of sort wrap up, egress issues... Attitudes..... I could keep going. I also understand the set back of calibrated to slow as well. Is there anybody out there like a part time sup. that calibrates your belt each preload shift from the reload. Anybody from Orlando Florida, Kissimmee center. I understand that they calibrate their belt every morning, by marking the belt and a stop watch. ***** I also thought there was the same for a boxline as well.. so chargers and loader could do their jobs in a safe manner as well. Safety, Service, Production. In that order...isn't that the order
