ABSTRACT:
The invention contemplates incorporation of a vertically guided jack-driven mechanism at the point of suspension-cable connection to an elevator car, the jack and all means for control thereof being carried by the elevator car, so that floor-leveling trim adjustment of car floor to landing level can be performed independent of the cable suspension and while the cable-sheave drive motor of the hoist system is at rest. Floor-leveling jack operation is fast and may be initiated upon hoist-system delivery of the car to the approximate level of a destination landing, and the jack may be reset while the hoist system is in operation to deliver the car to the approximate level of a different destination landing.
