Abstract: A system for releveling an elevator car floor with a landing floor includes a load weight sensor to sense a load weight of an elevator car at a landing floor, and a releveling controller operably connected to the load weight sensor to calculate a corrective velocity for the elevator car based on the load weight and estimates of the effective stiffnesses at the landing floor. A machine is operably connected to the releveling controller with both feedback and feedforward control and the elevator car to apply the corrective velocity to the elevator car thereby reducing a mismatch between the elevator car and the landing floor.

Abstract: An illustrative example elevator governor includes at least one flyweight configured to move a first distance between an initial position corresponding to a zero speed condition and an activation position corresponding to an elevator speed that reaches a predefined threshold. A biasing member biases the at least one flyweight toward the initial position. The biasing member is configured to allow the at least one flyweight to reach the activation position when the elevator speed reaches the predefined threshold. A flyweight position member sets a rest position of the at least one flyweight in the zero speed condition that is between the initial position and the activation position. A range of motion of the at least one flyweight is limited to a second, shorter distance between the rest position and the activation position.

Abstract: An elevator car is constructed and arranged to move along a hoistway. The car includes a cab support from below by a platform. A vertical member is connected to the platform via a flex joint and extends upward from platform for further elevator cab support. The flex joint facilitates cab isolation from vibration and noise.

Abstract: A system for determining stiffness of an elevator system tension member includes a landing floor indicator to transmit a landing floor signal of an elevator car to a stiffness estimator, and a car position encoder to transmit a car position signal of the elevator car in a hoistway to the stiffness estimator. A machine position encoder transmits a machine position signal to the stiffness estimator. The tension member is operably connected to the machine to move the elevator car along the hoistway. A load weight sensor is located at the elevator car to transmit a load weight signal of the elevator car to the stiffness estimator. The stiffness estimator utilizes at least the landing floor signal, the car position signal, the machine position signal and the load weight signal to calculate an estimated stiffness of the tension member.
