Abstract: An illustrative example embodiment of an elevator system includes a platform and a plurality of supports configured to selectively engage a nearby structure. The plurality of supports include at least a first support and a second support. The first and second supports alternate between engaging the nearby structure to support the platform while the other one of the supports is disengaged from the nearby structure. At least one of the first and second supports is configured to move relative to the platform while engaging the nearby structure to cause vertical movement of the platform.

Abstract: An illustrative example embodiment of a device for communicating information regarding an elevator car that moves along a vertical path includes at least one sensing portion configured to be supported on the elevator car and to sense at least one characteristic of the elevator car. A transmitter is configured to transmit a wirelessly communicated output indicating at least one condition based on the sensed characteristic. The transmitter is configured to use a first transmit power when the device is at a first location along the vertical path and to use a second, different transmit power when the device is at a second, different location along the vertical path.

Abstract: An illustrative example elevator system includes at least one elevator car that is moveable along a hoistway. An elevator controller is configured to respond to a communication from a portable device indicating a desire for the at least one elevator car to be placed in a maintenance mode and indicating a location of desired hoistway access. The controller automatically moves the elevator car to a determined positon based on the communication. That position corresponds to the location of the desired hoistway access. The controller performs at least one automated procedure to place the elevator car in the maintenance mode. The controller provides an indication to the portable device that the elevator car is in the determined position and that the automated procedure has been completed.
