  • Patent number: 11299372
    Abstract: 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.

  • Patent number: 11208296
    Abstract: 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.

  • Patent number: 11034550
    Abstract: 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.

  • Patent number: 10807833
    Abstract: 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.
