  • Publication number: 20200031626
    Abstract: An elevator system includes an elevator car with a car door arranged on the elevator car. The car door includes at least one door leaf movable in a translatory manner, a guide rail fastened to the elevator car, which guide rail forms a guide for the translatory movement of the door leaf, and a drive assembly for driving the door leaf. The drive assembly is movably mounted on the elevator car.

  • Patent number: 9650229
    Abstract: An elevator shaft door sill installation apparatus includes first and second assembly jig parts mounted at gage guide rails and a laser arranged at one of the parts for aligning the sill in the vertical direction. The alignment of the sill in the horizontal direction is undertaken with a line set including at least two lines, a first line having a first run extending from the first part to a first sill corner and from there by a second run to the second part, and a second line extending from the second part to a second sill corner. If the lines are tightened and a marking between the first and second runs is at the first corner of the sill, the sill is aligned in the horizontal direction.

  • Patent number: 8833036
    Abstract: A sill is aligned in the vertical direction on a laser line. The alignment of the sill in the horizontal direction is undertaken with a line set of an assembly jig. The line set includes at least two lines, for example a first line and a second line. The first line runs by a first run from the first part of the assembly jig to a third marking of the first line and from there by a second run to the second part of the assembly jig. If the lines are tightened and the marking is at one corner of the sill and the free end of the second line at the other corner of the sill, the sill is aligned in horizontal direction.

  • 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: 7909145
    Abstract: An elevator drive has a brake device with compression springs to actuate brake levers, and brake linings on a brake drum creating a braking force. A sensor is provided to detect the movement of a brake magnet armature tappet. A bracket is attached to the brake magnet tappet on one end and a distance piece carrying the sensor housing is arranged on the other end. A restoring lug is attached to the existing mechanical indicator. A monitor evaluates the sensor signal and turns off the elevator drive in the event of dangerous operational states via a safety circuit. The system allows the state of the brake device to be monitored. The more the brake linings wear off due to abrasion, the smaller the distance between the armature and the brake magnet housing. If the armature is in contact with the brake magnet housing, the braking ability of the brake linings is completely void.

  • Publication number: 20030136611
    Abstract: An apparatus and method for installing elevator shaft equipment includes utilizing an installing elevator to transport guide rail sections upwardly in an elevator shaft. The installing elevator includes an installing frame having at least one installation platform from which one or more movable parts can be retractably extended to change the size of the support area. Thus, the installing frame can be used for elevator shafts having different cross-sectional areas. At the completion of the shaft equipment installation, an elevator car is attached and the installing frame becomes part of the permanent elevator installation.
