A method for detecting a deterioration state in an elevator suspension member including electrically conductive cords uses a multiplexing unit (MU) to apply first and second alternating voltages to proximal ends of first and second groups of the cords respectively and connect the proximal end of a third group of the cords to a voltage measurement arrangement connected to a reference potential. Distal ends of the groups are connected together. A first neutral point voltage between the third proximal end and the reference potential is determined. The MU is switched to apply the first alternating voltage to the second proximal end, apply the second alternating voltage to the third proximal end and determine a second neutral point voltage between the first proximal end and the reference potential. The deterioration state of the suspension member arrangement is determined based on the first and second neutral point voltages.

The method comprises installing a lowermost first section of guide rail elements, moving a guide rail element upwards along a row of already installed guide rail elements with a transport apparatus, connecting the guide rail element to an upper end of the row of already installed guide rail elements and attaching the guide rail element to a wall of the shaft from a transport platform, moving the transport apparatus downwards along the row of already installed guide rails in order to fetch a new guide rail element.

A mounting device and a method for carrying out an installation process in a vertically extending elevator shaft of an elevator system include a carrier component, a mechatronic installation component and a displacement system. The displacement system displaces the carrier component vertically within the elevator shaft. The installation component is held on the carrier component and, at least semi-automatically, performs a mounting step as part of the installation process. The displacement system also displaces the carrier component horizontally in a shift direction within the elevator shaft between adjacent vertical car tracks.

The self-climbing installation platform comprises two decks positioned upon each other. Each deck comprises guide means supporting the deck movably on guide rails and locking means locking and unlocking the deck to the guide rails and/or to guide rail fixing means. Lifting means move the two decks along the guide rails in relation to each other. At least one power source provides power to the lifting means. The installation platform climbs stepwise along the guide rails by alternatingly locking and unlocking the lower and the upper deck to the guide rails and/or to the guide rail fixing means and thereafter raising the unlocked deck.

Methods and devices for optimizing control data of the elevator control unit of an existing or modernized elevator installation are described. An elevator control unit is connected to a programmable device. A three-dimensional digital replica data record, which can be generated by a computer program product, is loaded onto the programmable device as a simulation environment. The three-dimensional digital replica data record maps and simulates the existing or modernized elevator installation assigned to the elevator control unit. By testing the elevator control unit in the simulation environment, a parameter set for the elevator control unit of the existing or modernized elevator installation, which is matched for operation in the simulation environment, can be determined.

A pit leveling device for elevators, a leveling method and an elevator system. The pit leveling device includes a base having supporting portions and a plurality of supporting feet, wherein the plurality of supporting feet are detachably disposed below the supporting portions; a plurality of lifting devices disposed below the supporting portions for pushing the supporting portions away from at least a part of the supporting feet during an upward movement; and height compensators detachably disposed in gaps where the supporting portions are pushed away from at least a part of the supporting feet by the lifting devices.

In an elevator renewal construction method, a series of divided construction work steps includes a first divided construction work step including the steps of: installing a communication-enabled hall device at each hall; installing a communication-enabled car device in a car; and installing a communication relay device and connecting the communication relay device and an old control panel to each other; connecting the communication relay device and each of the communication-enabled hall devices to each other and connecting the communication relay device and the communication-enabled car device to each other. After termination of the first divided construction work step, the old control panel is in a state of being communicable with the communication-enabled hall devices and the communication-enabled car device via the communication relay device.

A measuring device for measuring an elevator shaft has two cable-like, elongate guide elements that extend in parallel with one another, a measuring platform and a lifting apparatus. Each of the guide elements is fixedly attached to an upper holding point and a lower holding point in the elevator shaft and is tensioned between the upper holding point and the lower holding point. The measuring platform has guide apparatuses that laterally support the measuring platform on the guide elements and guide the measuring platform parallel to the guide elements during a displacement movement in a displacement direction. The measuring platform has a distance measuring apparatus to measure lateral distances to the lateral walls of the elevator shaft. The lifting apparatus moves the measuring platform in the displacement direction.
