Disclosed is a fixture plate comprising a back plate defined by a member extending in a widthwise (W) direction and a height-wise (H) direction, a plurality of support arms including a first support arm and a second support arm connecting proximate a bottom edge of the back plate and spaced in the widthwise direction by a distance W, each of the plurality of support arms comprising a compound profile defining a pivot section and a support section the pivot section extending arcuately downward along the height-wise direction to a first distal end, the support section comprising a first portion forming a support base, the support base extending perpendicularly away from the back plate to a second distal end, and a second portion that forms a hook portion, the hook portion extending upwardly along the height-wise direction to a third distal end to from a free end of the support section.

Fixture plate and housing

A method includes determining that an elevator car is arriving at a landing at which re-leveling is anticipated; upon the elevator car arriving at the landing at which re-leveling is anticipated, initiating the at least one of a brake cycling operation and a power cycling operation to reduce elevator car sag at the landing; monitoring transfer of weight to or from the elevator car at the landing over a period of time; terminating the at least one of the brake cycling operation and the power cycling operation upon at least one of (i) the transfer of weight to or from the elevator car at the landing over the period of time being less than a threshold and (ii) the elevator car sag at the landing meeting a sag threshold.

Brake operation management in elevators

Embodiments are directed to determining that an elevator car of an elevator system is approaching a landing, obtaining, by a controller, a value for at least one parameter associated with the elevator system based on the determination that the elevator car is approaching the landing, determining that the elevator car arrives at the landing within a threshold distance, determining, by the controller, when to engage in at least one of a brake cycling operation and a power cycling operation based on the value for the at least one parameter and based on determining that the elevator car arrives at the landing within the threshold distance, and initiating the at least one of a brake cycling operation and a power cycling operation at a time corresponding to the determination of when to engage in the at least one of a brake cycling operation and a power cycling operation.

An exemplary elevator passenger interface device includes a touch screen configured to allow a passenger to indicate a request for elevator service by touching the screen. An assistance button is positioned near the touch screen. A controller is configured to determine a destination requested by a passenger touching the screen. The controller is also configured to determine whether the assistance button has been manipulated and then to determine a destination requested by a passenger from a subsequent manipulation of the assistance button.

Elevator passenger interface including special assistance features

An exemplary method of controlling an elevator system includes determining that a temporary heavy traffic condition exists that includes a plurality of passengers requiring elevator service from an originating floor in the building that is distinct from a lobby floor. At least one elevator car out of a plurality of elevator cars within the building is temporarily dedicated to carry the passengers from the originating floor. A peak travel scheduling strategy is temporarily used for controlling the dedicated elevator car or cars for a selected period of time.

Elevator system with dynamic traffic profile solutions

An exemplary elevator system includes a first controller configured to recognize a hall call signal that indicates a passenger's desire to board an elevator car at a particular landing. The first controller is associated with at least one elevator car for assigning a hall call request to that elevator car. A second controller is configured to recognize a destination request that indicates a passenger's desire to be carried to a particular level. The destination request originates outside of an elevator car. The second controller is associated with at least one elevator car for assigning a destination request to that elevator car. The second controller is configured to determine whether a selected condition will be satisfied if a received destination request is serviced by an elevator car associated with the second controller. The second controller handles the received destination request in that manner if the condition will be satisfied. A cross dispatcher is configured to communicate with the second controller and to handle the destination request. If the condition will not be satisfied, the cross dispatcher provides an indication of a hall call signal corresponding to the received destination request to the first controller.
