Abstract
A method and system for managing an elevator system (10), includes providing a plurality of elevator cars (14) to travel in a hoistway (11), and selectively introducing and removing at least one of the plurality of elevator cars (14) to and from the hoistway (11) via a loading station (50).
Claims16
An elevator system comprising:
- a plurality of elevator cars to travel in a hoistway, the plurality of elevator cars propelled by a motor;
- a loading station to selectively introduce and remove at least one of the plurality of elevator cars to and from the hoistway;
- and
- an evaluation station configured to evaluate at least one of the plurality of elevator cars;
- wherein the evaluation station evaluates at least one of a thrust performance of the motor and a power performance of an on-car power system of the at least one of the plurality of elevator cars when positioned in the evaluation station to determine a condition of the at least one of the plurality of elevator cars;
- the evaluation station signaling the loading station to remove the at least one of the plurality of elevator cars from the hoistway in response to the condition of at least one of the plurality of elevator cars.
