Abstract
An apparatus for automatically equalizing the uneven tension between ropes of an elevator in combination with a load cell to determine elevator load. The load of an elevator car having multiple tension members is automatically balanced while load is measured using a single load cell. The incorporation of a load cell with an autobalancing system allows for an accurate measure of an elevator load to be taken while providing the benefits of having uniform rope lengths in the elevator system. The apparatus may have various arrangements, including an in-line configuration and a grouped configuration. The apparatus may also dampen the vibration energy that is usually imparted to an elevator car.
