Had to pick between a new hoist rope or a full motor rebuild on a 15-year-old traction unit in a downtown office building, and going with the rope first saved the building owner $8,000 in immediate costs.
The motor had a slight hum, but the rope showed three broken outer wires in a 10-foot section, so I argued for the rope replacement first, and after we swapped it, the car ran smooth and the motor noise actually went away, which makes me think the strain was causing it. Anyone ever have a secondary symptom clear up after fixing the primary, obvious fault?
