Publication number: 20200346892Abstract: An elevator system (1) includes a load sensor (4, 24, 34, 44), a flexible member (2, 18, 22) and an elevator unit (10, 20, 28) arranged to move vertically in a hoistway. The system is arranged such that the load sensor (4, 24, 34, 44) detects a load from at least a fraction of the flexible member (2, 18, 22) and the fraction of the flexible member (2, 18, 22) that applies load to the load sensor (4, 24, 34, 44) changes as the elevator unit (10, 20, 28) moves vertically in the hoistway. The system further includes a non-volatile memory, arranged to store load conversion information for converting the detected load into an elevator unit position.Type: ApplicationFiled: May 1, 2020Publication date: November 5, 2020Inventors: Ergün Alkan, Helmut Lothar Schroeder-Brumloop

Patent number: 9637349Abstract: An example elevator brake includes a first braking member that is biased by a first spring member into engagement with a braking surface. The first braking member includes a first armature arranged to be actuated by an electromagnetic actuator to disengage the first braking member from the braking surface against the biasing force of the first spring member. A second braking member is biased by a second spring member into engagement with a braking surface. The second braking member includes a second armature arranged to be actuated by an electromagnetic actuator to disengage the second braking member against the biasing force of the second spring member. A first electromagnetic actuator actuates the first armature and a second electromagnetic actuator actuates the second armature.Type: GrantFiled: April 30, 2014Date of Patent: May 2, 2017Assignee: Otis Elevator CompanyInventors: Helmut Lothar Schroeder-Brumloop, Pascal Rebillard, Gerard Sirigu, Olivier Stanislas Dukacz, Ralph S.
