A method of operating an elevator system, for example operated by linear motors, wherein the elevator system includes a shaft system including at least one vertical elevator shaft, and a multiplicity of elevator cars which respectively have a plurality of functional components for carrying out different functions. The method provides that in a special operating mode of the elevator system, a first elevator car is assigned at least one auxiliary device, the auxiliary device providing a replacement function for at least one function of one of the functional components of the first elevator car, the corresponding function of a functional component of the first elevator car being replaced with the replacement function provided by the auxiliary device, and the elevator system continuing to be operated by using the replacement function provided. The invention furthermore relates to an elevator system configured for carrying out such a method.

Method for operating a lift system and lift system designed for carrying out the method

A braking device may include first and second brake pads disposed opposite one another about a guide rail, for developing braking forces when the brake pads engage the guide rail. The first brake pad has a wedge shape and may taper in a wedge direction. A front side of the first brake pad facing the guide rail is aligned parallel to the guide rail, and a rear side of the first brake pad is angled corresponding to the wedge shape. The rear side of the first brake pad lies in a sliding manner against a contact surface of a first brake pad seat disposed at an angle corresponding to the first brake pad. In a first setting a locking device unblocks a sliding movement of the first brake pad, and in a second setting the locking device blocks the sliding movement of the first brake pad.

Braking device for a car of a lift system

An elevator system may comprise a vertical guide rail, a horizontal guide rail, a shaft relative to which at least one of the first or second guide rail is kept stationary, a rotatable rail segment, a car that is movable along the guide rails and switchable between the first and second guide rails via the rail segment, and locking devices configured to selectively secure an orientation of the car and/or the rail segment. A method for operating the elevator system may involve positioning the car into a transfer position on the rail segment while the rotatable rail segment is aligned with the first guide rail, rotating the rail segment into alignment with the second rail segment whereby movement of the rail segment is braked by a rotary brake, and securing the rotational position of the rail segment relative to the shaft with one of the locking devices.

Method for operating an elevator system

A transportation device such as an elevator installation, an escalator, or a moving walkway may comprise a person conveying unit and an electromagnetic linear drive for driving the person conveying unit. The electromagnetic linear drive may include a stator segment and a runner element. The runner element can be driven by the force of an electromagnetic field of the stator segment in a first drive direction or in an opposite second drive direction. The runner element is movably mounted on the person conveying unit such that a magnetic resistance in an air gap between the stator segment and the runner element is adjustable depending on a drive force acting between the stator segment and the runner element.
