  • Patent number: 8230979
    Abstract: The invention relates to a method and an arrangement for transporting people in a building using an elevator installation (10) having at least one elevator cage (11). The elevator cage (11) is entered by people on at least one first or one second access floor (S1, S2). In order to increase the transport efficiency, at least one target floor (S3, S4, S5, S6, S7) is associated with each access floor (S1, S2) in a fixed manner, in such a way that the elevator cage (11) travels from the first access floor (S1) to the associated first target floor (S4, S5) and from the second access floor (S2) to the associated second target floor (S5, S6, S7).

  • Patent number: 8210321
    Abstract: A method and system for transporting people in a building using an elevator installation having at least one elevator cage determines a destination story based on the movement direction of people on an access story. The movement direction of one or more persons on an access story is detected using a movement direction sensor. The destination story may be based on detected movement and the access story on which the movement is detected. The elevator cage is entered by people on at least one first access floor (S1, S2). In order to increase the transport efficiency at least one target floor (S3, S4, S5, S6, S7) is associated with the access floor (S1, S2) in a fixed manner, in such a way that the elevator cage (11) travels from the first access floor (S1, S2) to the target floor (S3, S4, S5, S6, S7) associated therewith.

  • Patent number: 8020667
    Abstract: A lift apparatus to deploy from a storage position in a ceiling to a working position supported by the floor of a room below the ceiling where the lift apparatus is stored. A electrically motor powered drive raises a lift platform and lowers a lift platform to carry items from the room to an attic above the room. Controls are used to deploy the lift apparatus and to operate the lift platform on the lift apparatus. Preferred method of operating the lift apparatus is an acme screw drive which provides an appropriate mechanical advantage reducing the size of the motor required, but also will prevent downward movement either of the lift apparatus during the deployment procedure or of the lift platform while moving items from the attic to the room below the attic or from the room below the attic to the attic. The lift apparatus is supported by the floor and does not require any special bracing or strengthening of floor joists.

  • Patent number: 8016081
    Abstract: An elevator drive with a brake device has compression springs that act on brake levers, whereby brake linings generate a brake force on a brake drum. The more the brake linings wear due to abrasion, the smaller the distance of the plunger from the brake magnet housing becomes. Should the plunger come into contact with the brake magnet housing, the braking capacity of the brake linings is completely eliminated creating an operating condition that is dangerous for elevator users. A switch is provided that detects a minimum distance. The switch can be arranged on the plunger of the brake magnet and detect the minimum distance to the brake magnet housing or, in the case of a retrofit, the switch can be arranged on the brake magnet rod and, for example, detect the distance of the second joint from the brake magnet housing, and at the minimum distance the switch switches.

  • Patent number: 8011481
    Abstract: A method for monitoring the operating state of an elevator drive having a brake includes the mounting of a sensor on a movable brake part. The sensor generates an output proportional to the extent of relative movement between the brake part upon which it is mounted and a fixed brake part. The sensor output is monitored to provide an indication of the operating state of the drive and may be combined with other data to provide indications of a variety of drive states.

  • Patent number: 8011478
    Abstract: A vibration damping system for an elevator is provided with a damping device (5) that is provided between a cab (1) and a car frame (2) for supporting the cab (1) and whose damping coefficient can be changed. A speed detector detects the traveling speed of a reference elevator car, and a calculation unit (15) receiving the traveling speed detected by the speed detector calculates a control signal for the damping device (5), and outputs the control signal to the damping device. The calculation unit (15) controls the damping device (5) in such a way that, in the case where the traveling speed exceeds a predetermined value, the damping coefficient of the damping device (5) is larger than that in the case where the traveling speed is the same as or smaller than the predetermined value.

  • Patent number: 7992686
    Abstract: A method for counting the pallets or loads moved by a lift truck using internal sensors is disclosed. The lift truck includes a weight sensor for weighing a load, a height sensor, for measuring a height of the forks, and a distance sensor for determining whether the vehicle has moved. When the data from each of these sensors exceeds a corresponding minimum value, a vehicle control system increments a pallet counter. A count of the number of pallets moved is therefore maintained without the need for tracking specific pallets of for adding expensive components and devices.

  • Patent number: 7980362
    Abstract: Safety equipment for an elevator installation with an upper elevator car and a lower elevator car, which cars are both movable substantially independently along a vertical direction in a common elevator shaft of the elevator installation includes a first electro-optical detection system with a first light source in a lower region of the upper elevator car and with a first detector which comprises a light-sensitive first sensor region in an upper region of the lower elevator car. The first light source issues a focused first light beam at a first angle with respect to the vertical direction. The first angle is predetermined such that on approach of the upper and the lower elevator cars the first light beam is incident on the first sensor region and thus is detectable by the first detector. In this case, the first detector triggers a reaction.
