摘要:
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.

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 (εult,Ind) which is smaller than the breaking elongation (εult,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.

An elevator system can be operated while recording the energy consumption of at least one energy consumer of the elevator system and at least one traffic situation of the elevator system. At least one energy consumption value is determined for the recorded energy consumption and the recorded traffic situation, and the calculated energy consumption value is output to at least one output means.

A device can actuate and reset a safety gear in an elevator system. The device contains a pressure accumulator, possibly a compression spring, which, in case of need, can move at least two engagement elements of the safety gear essentially synchronously into an engaged position, and a remotely actuatable resetting device, which can retension the pressure accumulator into a ready position.

An elevator installation includes a cage, a counterweight which balances the cage and a supporting and/or drive means at which the cage and the counterweight are suspended. The elevator installation has a sound pick-up designed for detecting solid-borne sound generated at the counterweight.
摘要:
A support for an elevator installation includes at least two cables of several strands each, which are designed for acceptance of force in longitudinal direction, and wherein the cables are arranged along the longitudinal direction at a spacing from one another and are connected by a cable casing, which forms a web between the two cables. 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.

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.
摘要:
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.

摘要:
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.
