  • 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: 9676595
    Abstract: A method of manufacturing an elevator includes installing a movable supporting platform and an elevator car in the elevator hoistway; taking the elevator car into use to serve passengers and/or to transport goods; removing the elevator car from use; changing the service range of the elevator car to reach higher up in the elevator hoistway by lifting the supporting platform higher up in the elevator hoistway; and taking the elevator car back into use. The elevator is reeved to include construction-time hoisting roping, which includes one or more ropes, the longitudinal power transmission capacity of which is based at least essentially on non-metallic fibers in the longitudinal direction of the rope. In the method, guide rails to be fixed with guide rail brackets can additionally be installed by the aid of an installation device. An elevator arrangement can be used to perform the method.

  • Patent number: 8851238
    Abstract: Apparatus for raising and lowering objects. In accordance with some embodiments, a winch motor is adapted to rotate a winch member in opposing first and second directions to wrap/unwrap a portion of a cable on/from the winch member to raise and lower a lifting platform assembly, respectively. A tension detection switch assembly includes an on/off switch connected to the winch motor and a biasing member which exerts a bias force upon the winch member to nominally deflect the winch member to a first position which sets the switch to deactivate the winch motor in an absence of tension in the cable from the lifting platform assembly. A presence of tension in the cable from the lifting platform assembly deflects the winch member to a second position which sets the switch to facilitate activation of the winch motor.

    Abstract: A segmented elevator sheave assembly has independently variable shoulder and crowning elements for use with flexible flat ropes in an elevator system. This enables selection of high-traction surface finish and crowning for the sheave groove that contacts a belt, and of low-traction, smooth sheave groove shoulders having a low friction coefficient that may inadvertently contact the belt side surfaces. This configuration is more forgiving to angular misalignment of the sheave and reduces the likelihood of premature degradation of a flat flexible rope due side-surface scuffing along sheave groove shoulders.
