I was setting governor rope tension wrong for years until a call in Atlanta
I was on a call for a stuck car in a high rise in Atlanta last spring. The governor rope was jumping off the sheave, and I figured it was just a worn guide. I had my tension gauge set to what I always used, about 150 pounds. An older mechanic from the local union hall showed up to help, and he just shook his head. He said, 'Kid, you're reading the gauge right, but you're checking it with the car at the wrong landing.' I always checked it from the top floor. He showed me you have to check it from the lowest possible point of travel with the car empty, or the weight of the rope itself throws it off. I'd been over-tensioning every single one, which was causing premature wear and those jumps. How do you guys handle governor rope tension on really tall runs? Do you factor in the rope weight differently?
