An elevator system for a building, wherein an elevator shaft becomes taller as the building height increases during a construction phase, includes a self-moving construction-phase elevator car guided on a guide rail section(s) for conveying persons or goods during the construction phase, an assembly platform arranged above the car from which the guide rail section is elongated upwards in a rail assembly phase, an upper protection platform temporarily fixed in the elevator shaft on which the assembly platform is suspended via a cable-based lifting device or is suspended in the rail assembly phase, a lower protection platform, wherein the assembly platform is moved vertically between the upper platform and the lower platform by the lifting device during the rail assembly phase, and a docking device temporarily suspending the car on the lower platform to secure the car for evacuations, the docking device connecting the car to the lifting device.

Elevator system

A measuring tape arrangement is used in an elevator system for determining a position of an elevator car along a travel path. The measuring tape arrangement has a one-piece measuring tape arranged along the travel path, wherein varying location information is stored along the measuring tape, by which information a current position of the car relative to the measuring tape can be determined, and a retaining structure arranged at an upper end of the travel path on which structure the measuring tape is fastened by a fastening device at a fixed position relative to the travel path. A receiving device receiving a measuring tape supply is arranged on the retaining structure, wherein a measuring tape piece of the measuring tape supply can arranged along an extension portion when the travel path is extended upwards by one extension portion.

An elevator system includes a lifting platform for securing at a plurality of securing positions in an elevator shaft and at least one guide rail for vertically guiding an elevator car in the elevator shaft. The lifting platform has a protective roof that protects the lifting platform against falling objects, wherein the protective roof has a rail opening, through which the guide rail extends, and wherein the protective roof has a cover covering the rail opening, the cover having a cover opening through which the guide rail extends.

A climbing elevator system has an elevator shaft and an elevator car, a lifting platform, and a supporting device, wherein, in the course of different construction phases of a building, the lifting platform can be anchored at various positions within the elevator shaft. A protective roof is arranged above components of the lifting platform that are to be protected, such as a drive machine. The protective roof has a central roof structure and a peripheral flank structure that has flank walls fixed to the lateral edges of the central roof structure and project outwardly from the central roof structure at an angle with respect to the horizontal. Because of the inclined arrangement of the flank walls, the flank structure can better withstand falling objects and better protect components located underneath. Cantilevered edge regions of the flank walls can be supported on side walls of the elevator shaft.

A method for constructing at least two elevators in a building under construction adapts the usable lifting heights of the elevators to an increasing height of the building, wherein each of the elevators is arranged in an elevator shaft of the building associated with the elevator and includes a drive platform having an elevator drive machine that supports and drives an elevator car and a counterweight by a traction sheave and at least one flexible suspension device. In order to adapt the usable lifting heights, lifting operations are performed in which in alternation one of the drive platforms is raised to a higher level in the associated elevator shaft and is locked there. A single lifting platform is temporarily fastened above the particular drive platform to be lifted to apply a lifting force required to raise the drive platform, which force is transferred to supporting elements of the elevator shaft.

Method for constructing an elevator system having increasing usable lifting height

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.

An elevator system arranged in an elevator shaft of a building in the construction phase grows with the building using a lifting process. The system includes a machine platform with an elevator drive machine and an elevator car suspended on the machine platform by a carrier. The elevator car is raised during the lifting process by a lifting device. The elevator system also includes an assembly platform that can be mechanically moved in relation to the machine platform along the elevator shaft. The lifting device includes a drive arranged on the machine platform and is also used to move the assembly platform.

Elevator system and method for constructing such an elevator system

A method for constructing an elevator system in a building includes performing at least one lifting operation to adapt a usable lifting height of the elevator system to an increasing height of the building. A drive platform supporting an elevator drive machine and, by a flexible support, an elevator car and a counterweight is raised during the lifting operation. A difference between an elevator-car-side support weight and a counterweight-side support weight is substantially compensated by a compensating tension device guided from a bottom side of the elevator car to a bottom side of the counterweight by a deflecting device including two roller assemblies having deflecting rollers forming a compensating tension loop. A distance between the roller assemblies is reduced before and/or during the lifting operation such that an amount of the compensating tension device required for the performance of the lifting operation is released from the compensating tension loop.

Method for constructing an elevator system having an adaptable usable lifting height

A method for erecting an elevator system in an elevator shaft of a building includes performing at least one lift process to adapt a usable lift height of the elevator system to an increasing height of the building. During the lift process, a drive platform, which supports an elevator drive machine and, via a flexible support, an elevator car and a counterweight, is lifted along at least one elevator car guide rail. Prior to the lift process, the at least one elevator car guide rail is elongated in the upwards direction above the drive platform and fixed to a shaft wall of the elevator shaft by at least one auxiliary support in the region of the elongation. After the lift process, the at least one auxiliary support, which then lies below the drive platform, is replaced by a final guide rail mounting which is designed differently than the auxiliary support.
