Abstract
An elevator load weighing system (100) includes a brake assembly (104) configured to apply a braking force that inhibits vertical movement of an elevator car (106), and rotate in response to realizing a torque applied thereto. A position monitoring mechanism (112) is coupled to the brake assembly (104) and is configured to output a position signal in response to a rotation of the brake assembly (104). An electronic elevator control module (102) is configured to determine a zero-torque position of the brake assembly (104) prior to engaging the brake assembly (104). The electronic elevator control module (102) is further configured to detect at least one rotational brake displacement of the brake assembly (104) based on the position signal.
