An elevator car may tilt due to an unbalance in its own weight. Excessive car tilt can adversely affect ride comfort and the lifespan of equipment. Therefore, the elevator installation process includes measuring the car’s posture and adjusting its unbalanced mass. These processes require repeated operations to enhance adjustment accuracy, which causes prolonged working hours and an increased burden on workers. In order to improve this situation, we developed a measurement system for the adjustment of the car’s unbalanced mass. This system can automate the measurement of the car posture and find the moment to counterbalance any unbalanced mass based on the regression curve relating to the car posture and the moment acting on it. Furthermore, this system presents the optimal arrangement pattern for the additional mass that achieve the counterbalancing moment. This paper presents the general configuration of the system, the method for finding the counterbalance moment and the optimal arrangement pattern, and the results of verification test of the system.
