Abstract:
An elevator has an elevator car supporting frame that can travel in a travel space provided for a journey of the elevator car supporting frame. The elevator installation is also provided with a first elevator car and a second elevator car arranged on the elevator car supporting frame. Furthermore, a hydraulic moving element is arranged in a lower end region of the travel space. In this way, the first elevator car can be moved in relation to the second elevator car, by the moving device, in the lower end region of the travel space.
Abstract:
An elevator arrangement includes a plurality of elevators in a building, which plurality includes a plurality of zoned elevators moving in an elevator hoistway, which have different ranges of movement of the elevator car in the building to each other, and which zoned elevators each have a top limit and a bottom limit of the range of movement of the elevator car, to above the top limit and to below the bottom limit of which range of movement travel of the elevator car of the zoned elevator in question is prevented. The vertical location, in relation to the building, of the top limit and/or bottom limit of the range of movement of the elevator car of each aforementioned zoned elevator can be changed. The arrangement also comprises a lobby elevator, the range of movement of the elevator car of which differs from the ranges of movement of the elevator cars of the aforementioned zoned elevators, and the stopping floors of the lobby elevator comprise a plurality of lobby floors, each of which is a stopping floor of one or more zoned elevators belonging to the aforementioned zoned elevator plurality. A method is provided for re-adjusting the elevator arrangement, wherein the range of movement of the elevator car of the zoned elevator in question is changed to reach to a different height in the elevator hoistway by changing the vertical location in relation to the building of the top limit and/or the bottom limit of the range of movement of the elevator car of the zoned elevator in question.
Abstract:
An elevator system includes a car, configured to travel through a hoistway; a first stationary drive unit, configured to be mounted in a hoistway, a first movable drive unit, configured to be functionally coupled to the car and to the first stationary drive unit, and a second movable drive unit, configured to be functionally coupled to the car and to the first stationary drive unit.
Abstract:
An elevator system is a one-shaft double-car elevator system and includes a floor-recognition abnormality detector to detect, with respect to one of the cars, a floor recognition abnormality that at least one of a car position and floor information cannot be normally recognized, a terminal-floor driving mechanism to make, on the basis of a notification of floor-recognition abnormality information detected by the floor-recognition abnormality detector, the other one of the cars travel to a terminal floor in a direction opposite to a direction toward the one of the cars, and a floor-recognition-abnormality correcting-operation mechanism to perform, on the basis of terminal-floor traveling information from the terminal-floor driving mechanism, a floor-recognition-abnormality correcting-operation to correct the floor recognition abnormality of the one of the cars; therefore, an operation to recover from the abnormality can be safely performed without collision of the cars.
