Patent number: 9868615Abstract: Stall condition in an elevator is potentially dangerous situation if it causes slack to the ropes of the elevator. In such situation a counterweight or elevator car does not move even if the hoisting machine is still operating. This situation may be prevented by stopping the elevator as early as possible after detecting such stall condition. The detection of the stall condition is based on monitoring the torque generated by the hoisting machine of the elevator. When rapid change in the torque is detected a stall condition is suspected. The elevator may be stopped or an alarm may be launched when the stall condition is suspected.Type: GrantFiled: October 15, 2014Date of Patent: January 16, 2018Assignee: Kone CorporationInventors: Jari Helvilä, Sakari Korvenranta, Petter Martonen, Petteri Valjus, Jukka Laitinen, Lauri Stolt
