Abstract: An elevator system having at least two elevators, wherein at least one of the elevators is designated as an emergency personnel elevator, can be operated to allow a firefighter to commandeer a second elevator for the purpose of ferrying persons to a safe evacuation floor. The elevator system is configured to determine if a request for an evacuation elevator originates from the firefighter elevator car positioned at one of several floors of a building. In response to the request, an elevator car other than the emergency personnel elevator car is designated as the evacuation elevator car. Further, the evacuation elevator car is dispatched to the floor the emergency personnel elevator car is positioned, and the evacuation elevator car is dispatched to a predefined evacuation floor upon receipt of an evacuation request made by the firefighter.

Abstract: Brake equipment, for an elevator installation, includes: a static element; a movable element movable relative to the static element in a first degree of freedom, wherein selectably a first frictional contact is produced in a first contact surface between the static element and the movable element by a controllable normal force acting in a second degree of freedom, and a first friction force opposes movement of the movable element relative to the static element; and a relative element, wherein a second frictional contact is produced in a second contact surface between the movable element and the relative element by the normal force, and a second friction force opposes movement of the movable element relative to the relative element. The relative element is movable in the first degree of freedom relative to the static element between a normal position and a braking position and is resiliently biased into the normal position.

Abstract: The step (1) comprises cheeks (5) which are manufactured from deep drawing sheet metal, and a tread element (22) and a deep drawn seating element (24). The arc (BO1) of the seating element (24) follows a first radius (R1) in the upper region and a second radius (R2) in the lower region, wherein the second radius (R2) is somewhat smaller than the first radius (R1). The sheet (BO1) of the seating element (24) merges smoothly at the line (ÜR) from one radius into the other radius. By way of the two radii (R1, R2), the size of the step gap between the tread element (22) and the seating element (24) of the adjacent step is independent of the position of the step gap; the step gap always remains very small, for example smaller than 2.8 mm. As a result, the risk of clothing items, sharp objects, shoes, children's fingers and so on getting jammed is reduced considerably.
