Abstract: An elevator has a car movable within a hoistway, a rack extending along the hoistway, the rack having a toothed profile with wave troughs and wave crests and a drive mounted in proximity to the rack so that the drive interacts with the rack to move the car. The drive includes a roller pinion unit fixedly mounted on a shaft and having a predetermined number of roller pinions arranged in a circle around the shaft and extending parallel to the shaft. The roller pinion unit interacts with the toothed profile of the rack. The drive also includes a motor unit configured to rotate the shaft. Optionally, the drive includes a brake unit configured to act on the shaft.

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.

Abstract: The invention relates to an elevator system having an elevator car, a load carrier for holding and/or moving the elevator car, and a detector device for detecting a condition of the load carrier, the detector device having an ultrasonic emitter for generating and coupling ultrasonic waves into the load carrier and for generating ultrasonic waves in the load carrier, and an ultrasonic receiver for detecting ultrasonic waves of the load carrier.

Abstract: An elevator system with a car or platform to transport passengers and/or goods as well as with a counterweight, which are arranged as traversable or movable along a travel path, and which are coupled and/or with a drive by a suspension element interrelating their motion. The suspension element is guided and/or driven by a traction sheave and/or a drive shaft and/or a deflecting pulley. The suspension element is sheathed and/or belt-type, with a first layer made of a first plasticizable and/or elastomeric material, containing a first exterior surface, and with at least one tension member—rope-type, tissue-type, or comprising a multitude of partial elements—that is embedded in the first layer of the suspension element. A manufacturing procedure for one of the suspension elements is provided.

Abstract: An elevator has a mechanical linear drive arranged laterally at an elevator shaft head to drive at least one belt that moves a car and a counterweight in the shaft. The belt is fixed in the shaft at opposite ends and extends about a drive wheel of the elevator drive. Deflection rollers of the drive determine the angle of encirclement of the belt on the drive wheel.

Abstract: A belt has at least two fiber strands which have synthetic fiber threads twisted in themselves and are designed for acceptance of force in longitudinal direction. The strands are arranged at a spacing relative to one another along the longitudinal direction of the belt and are embedded in a belt casing. At least one of the strands comprises an electrically conductive indicator thread which is twisted together with the synthetic fiber threads of the strand, wherein the indicator thread is arranged outside the center of the fiber bundle. The indicator thread has a breaking elongation (?ult,Ind) which is smaller than the breaking elongation (?ult,Trag) of individual synthetic fiber threads of the strand. It can be electrically contacted so that an electrical monitoring of the integrity thereof is made possible.

Abstract: A support for an elevator installation includes at least two cables of several strands each, which cables are designed for acceptance of force in a longitudinal direction, and wherein the cables are arranged along the longitudinal direction of the support at a spacing from one another and are connected by a cable casing. The cable casing has a transition region which lies between the cables and is provided with openings and webs. The webs are formed to enable a relative displacement of the cables relative to one another in the longitudinal direction.

Connectors are provided in the region of the web, wherein the connectors are so designed that they enable a guided relative movement of the cables relative to one another in the longitudinal direction.

Abstract: A rope apparatus includes two ropes of synthetic fiber strands arranged for taking up force applied in a lengthwise direction. The ropes are arranged a predetermined distance apart and are fixed by a rope sheathing forming a fixed link running in the lengthwise direction between the two ropes. The rope apparatus also has at least one reinforcement element for the mechanical reinforcement of the rope sheathing.

Abstract: A device for remote maintenance and monitoring of an elevator installation has at least one input for the detection of first signals from an elevator control and/or from a sensor, at least one output of second signals to a telecommunications network and a processor and a data memory. A set of remote maintenance functions is stored in the data memory and each of these remote maintenance functions is selectively activatable.

Abstract: An apparatus for moving a car along a travel path along guide rails includes a linear drive having a fixed first platform attached to the car and connected by springs with a movable second platform. Holding-units are attached to both platforms for engaging the guide rails and operating-units are connected between the platforms for relative movement. The holding-units and the operating-units include piezoelectric actuators that are selectively energized to move the car.
