Abstract: An elevator system and a multi-deck car for an elevator system. The elevator system has a multi-deck car that moves up and down along an elevator guide rail in an elevator shaft and comprises a first car and a second car connected to and located below the first car, wherein the second car is provided with a stop-support device configured to be operably engaged with a mating device mounted at a pre-set position on the elevator guide rail and/or the inner wall of the elevator shaft, for stopping and supporting the multi-deck car at the pre-set position upon engaging of the stop-support device and the mating device. The invention not only has advantages of quick and convenient operation, but also can effectively ensure the safety of both elevator equipment and field workers.
