automatically calculate a plurality of walk path options from the call kiosk to the designated elevator based on the graph-based map model;
determine an optimal walk path from the call kiosk to the designated elevator from the plurality of walk path options;
automatically render a floor map image displaying the optimal walk path between the call kiosk and the designated elevator; and
communicate the floor map image from the computing structure to the dispatch kiosk to enable the dispatch kiosk to exhibit the floor map image on the dispatch kiosk display in response to an elevator call.

LIFT INSTALLATION HAVING A COMPENSATING DEVICE, SO THAT A FIRST ROLLER IS LARGELY RELIEVED OF LOADING WHEN THE LIFT CAR IS AT REST

thyssenkrupp Elevator AG,...

1. A lift installation having a lift car which can be moved along a guide rail, the lift installation comprising:a first pair of rollers comprising a first and second roller receiving the guide rail therebetween;
a second pair of rollers comprising a first and second roller receiving the guide rail therebetween, wherein the lift installation has an apparatus for subjecting the lift car to a retaining force, wherein there is a horizontal offset between a point at which the retaining force takes effect and a center of gravity of the lift car, and therefore the lift car is subjected to a first torque; and
a first compensating device so that, when the lift car is at rest, the guide rail is subjected to sufficient force to give rise to a second torque, which at least partially compensates for the first torque, so that the first roller of the first pair of rollers is at least partially relieved of loading when the lift car is at rest,
wherein the first compensating device includes an actuator configured to move a contact element into and out of contact with the guide rail, wherein a travel distance of the actuator is selectively adjustable by a control unit such that the first compensating device is configured to selectively (i) relieve the entire loading on the first roller of the first pair of rollers, or (ii) partially relieve the loading on the first roller of the first pair of rollers.

ELEVATOR INSTALLATION

THYSSENKRUPP ELEVATOR AG,...

1. An elevator system comprising:a first elevator car;
a second elevator car disposed either above or below the first elevator car, wherein the first and second elevator cars are displaceable vertically upwards and downwards separately from one another in a shaft, wherein each of the first and second elevator cars is coupled to a counterweight via at least one cable arrangement, wherein at least one of the cable arrangements includes two cable portions that extend vertically in the shaft from one of the first and second elevator cars along mutually opposite sides of the other elevator car that is disposed between the two cable portions; and
a limiting roller rotatably mounted laterally alongside each of the two cable portions in one or more of the shaft, on the first elevator car, or the second elevator car disposed between the two cable portions, wherein each limiting roller is spaced apart from a corresponding one of the two cable portions such that each limiting roller comes into contact with a respective one of the two cable portions only in the event of horizontal cable deflection.
