A control system for an elevator is separated into a first assembly allocated outside and a second assembly allocated inside an elevator shaft. The first assembly includes a power switch for turning on/off the control system, a light switch for switching a light inside the shaft, a safety unit for protecting electrical safety of the control system, a communication unit for data communication with the elevator and/or an external communication device, and a bypass device for bypassing a safety chain of the elevator. The second assembly includes a power supply system for driving the elevator and/or for the safety chain, a monitoring system for monitoring the safety chain, a drive control unit for a drive motor, and a processor for data processing of the control system. The first assembly and the second assembly can communicate with each other and be connected respectively as segments into the safety chain.

An elevator system having: an elevator car vertically movable in an elevator shaft; a traction medium for raising and lowering the elevator car and being guided around at least one roller to the car and being fixed merely at ends thereof; a traction medium reservoir including at least one first deflecting axle and at least one second deflecting axle around which the traction medium is guided in alternation between the first and second axles so that a section, the length depending on the spacing of the first and second axles, of the traction medium is received in the reservoir; and a fixing unit to which the second deflecting axle is fixed, wherein the fixing unit is fastenable at different positions in the elevator shaft so that the spacing between the first and second axles is settable to determine the length of the traction medium received in the reservoir.

The invention relates to a method for constructing an elevator, comprising providing an elevator car; providing plurality of prefabricated hoistway modules to be piled on top of each other, each hoistway module bordering a hoistway space into which the whole elevator car or at least an upper or lower end thereof can be fitted to move; and piling said plurality of prefabricated modules on top of each other, such that the hoistway spaces of the prefabricated modules are vertically aligned forming a continuous vertically elongated hoistway where the elevator car can be fitted to move; and arranging the elevator car to be vertically movable in the hoistway. The invention also relates to an elevator obtained with the method.

A car for an elevator in an elevator shaft is suspended substantially in the center of gravity thereof at least in a ratio of 2:1 by a carrying apparatus guided via pulleys and is guided through car guides. The car has a car base, a car roof and car walls that define a passenger space. For using the car in a machine room-free elevator, to provide a shaft cross-section as large as possible and to reduce the required shaft pit depth and/or the required shaft head height, at least a first part of one of the pulleys is located between the car base and the car roof and a second part of the pulley is located in the car base or at the same height as the car base or in the car roof or at the same height as the car roof.

An elevator and an elevator control method are provided. The elevator includes a car (4) and counterweights (10); the elevator includes posts (2), a steel frame structure (13), and a power device (7), where the steel frame structure (13) is fixed on the top of the elevator, and the power device (7) is fixedly installed on the steel frame structure (13); and the counterweights (10) are disposed in the posts (2).

A building site device includes a climbing formwork platform for the floor-by-floor production of concreting portions of a building core having at least one elevator shaft. An elevator system has an elevator machine platform vertically movable in the elevator shaft. In order to minimize the use of lifting cranes and the manual raising of supporting structures, the elevator machine platform can be moved jointly with the climbing formwork platform.

Aspects of the present invention provide an approach for controlling energy generation by an airflow originating from a moving elevator cabin. Wing pressure pads are positioned outside the elevator cabin extending to walls of the elevator shaft for preventing an airflow in the elevator shaft from above the elevator cabin to an area in the shaft below the elevator cabin. The elevator shaft is pressure-tight, and the elevator shaft has, at one end of the elevator shaft, an air conduit in which a first power generator stage having a propeller-driven electrical power generator is positioned. The method further intercepts a floor selection for the cabin and disables the power generators if a floor difference from a current position of the elevator cabin to a target position of the elevator cabin is below a predefined threshold value.

The present approaches are in the in the field of vacuum (or pneumatic) elevators, where the elevator cabin is brought into motion in a vertically situated or vertically inclined and hermetically sealed elevator shaft by means of aerial pressure differential above and below the elevator cabin. Such approaches do not require having any ropes, pulleys, chains, gears, or hydraulics that are traditionally used in conventional elevator systems. More specifically, the present approaches are in the field of panoramic vacuum elevators, where the elevator hoistway is built of panoramic glass panels running from floor to ceiling of every floor and the elevator cabin is built of panoramic glass panels running from floor to the ceiling of the cabin, and that this type of elevator does not incorporate any metal constructive structures—frames, mesh, guides or rails that are traditionally used in every conventional elevator product.
