Abstract
According to one embodiment, a method for monitoring hoisting ropes in an elevator system comprises measuring tension of each hoisting rope, calculating a mean value of the tension in the hoisting ropes, determining if the tension in any rope is significantly higher than the mean value and providing a signal that rope snag has been detected if the tension in any rope is significantly higher than the mean value.
