  • Patent number: 11447365
    Abstract: A brake device for an elevator system generates a friction grip on an elevator rail and includes two legs with brake ends. The first leg is connected to a first articulation point of a transmission lever that has, located at a distance in a longitudinal direction from the first articulation point, a second articulation point that is connected to a first pivot of a pressure lever. The second leg is connected to a second pivot of the pressure lever. A third pivot of the pressure lever is connected to an articulation point of an actuating element (crank rod) whereby a longitudinal movement of the actuating element moves the brake device between a braking position with the brake ends spaced apart a minimum distance, and an opened position with the brake ends spaced apart a maximum distance. The actuating element longitudinal movement is predefined by first and second end points.

  • Patent number: 11420848
    Abstract: An elevator safety supervising entity (SSE) includes a car safety supervising unit (SSU) controlling functions of car safety components and having at least one car sensor sensing car-related parameters, a head SSU controlling functions of shaft safety components and having at least one shaft sensor sensing shaft-related parameters, and a data linkage transmitting signal data between the SSUs. Both SSUs detect a failure in the other one of the SSUs and in the data linkage signal data transmission and in response switch from a normal operation mode to a failure operation mode. In the failure operation mode, the SSUs operate autonomously to keep the elevator operative at least temporarily with a sufficiently high safety even when functions of the elevator SSE are disturbed due to failures and e.g. passengers may be evacuated from the elevator car before completely stopping elevator operation.

  • Patent number: 11407051
    Abstract: The application relates to a device and to an assembly line for producing a supporting structure for a passenger transport system, such as an escalator, which have a sequential arrangement of semi- or fully automatically operating and mutually cooperating assembly stations and a sequential order of assembly steps. Each of the assembly stations can include at least one holding device and at least a welding robot as well as, optionally, at least one handling robot. The assembly stations are configured in such a way that intermediate products can be produced efficiently by respective assembly steps. Each can be coordinated with a subsequent assembly station, so that the intermediate products can be passed sequentially with optimized short cycle times from assembly station to assembly station, to be able to provide a finished, load-bearing supporting structure at the end of the sequence.

  • Patent number: 11396440
    Abstract: A method determines information relating to elevator components received in an elevator shaft, the elevator components each being provided with a machine-readable marker on which component-specific information is stored, which information is read out by a marker reading device. In the method, a movable elevator element on which the marker reading device is arranged is moved through the elevator shaft and the component-specific information is read out from the markers. The markers can be, for example, markers that can be read out electromagnetically and in a contactless manner, such as RFID tags. The method also includes a comparison of the read-out component-specific information with nominal specifications, and the compiling of a report indicating instances of conformity and/or differences between the read-out component-specific information and the nominal specifications.

  • Patent number: 11365088
    Abstract: A monitoring device for monitoring a passenger transport system includes at least one sensor, a control unit, a bus, and at least one bus node connected to the bus. The bus node has a microprocessor and an inspection unit for data exchange with the control unit. A first program module in the microprocessor detects a state change of the sensor that is connected to an input of the microprocessor via a transmission line and spontaneously transmits a corresponding state message to the control unit. A second program module in the inspection unit, after receiving an instruction from the control unit, transmits an activation signal to a coupling point in the bus node that simulates a state change of the sensor, the activation signal being superimposed on a sensor signal and/or being coupled into a power supply line connected to the sensor.

  • Patent number: 11365093
    Abstract: A method for detecting a deterioration state in an elevator suspension member including electrically conductive cords uses a multiplexing unit (MU) to apply first and second alternating voltages to proximal ends of first and second groups of the cords respectively and connect the proximal end of a third group of the cords to a voltage measurement arrangement connected to a reference potential. Distal ends of the groups are connected together. A first neutral point voltage between the third proximal end and the reference potential is determined. The MU is switched to apply the first alternating voltage to the second proximal end, apply the second alternating voltage to the third proximal end and determine a second neutral point voltage between the first proximal end and the reference potential. The deterioration state of the suspension member arrangement is determined based on the first and second neutral point voltages.

  • Patent number: 11319185
    Abstract: An elevator system has a central control unit for generating control signals and/or processing sensor signals and controlling functions of the system, a plurality of field devices distributed inside a structure accommodating the system, preferably along an elevator shaft, and a field bus system for interchanging the signals between the control unit and the field devices. Each field device outputs sensor signals generated by a sensor and/or receives control signals to be implemented by an actuator. Data packets including the signals are interchanged in a serial manner between the control unit and all field devices in a summation frame method using a closed ring topology. Each field device has a driver to insert the sensor signals into the data packet or to remove the control signals from the data packet. Data and signal transmission is thereby carried out quickly and safely in a safety circuit of the elevator system.

  • Patent number: 11305966
    Abstract: A method and a correspondingly configured device detect damage or defects in a support, including at least one tension member, for an elevator system. A pulse generator generates at least one electrical digital input signal that represents at least one first binary number and is fed to the tension member. After the digital input signal has passed through the tension member, it is detected as a digital output signal that likewise represents at least one second binary number. The second binary number is then compared, in particular compared digit by digit or bit by bit, with a setpoint binary number and/or directly with the first binary number. Damage in the tension member is determined on the basis of an issued comparison result. If the second binary number deviates from the setpoint binary number and/or from the first binary number, a fault message is generated.

  • Patent number: 11305965
    Abstract: An elevator has a drive unit displacing an elevator car in an elevator hoistway, an elevator controller controlling operation of the drive unit, multiple safety switches switchable upon occurrence of safety relevant events, and a safety chain overlay control unit including a safety PLC. The PLC has first connectors connected to first safety switch contacts and second connectors connected to second safety switch contacts. The PLC monitors a current safety status of the elevator and identifies a safety critical status by detecting when at least one of the safety switches changes its switching state and comparing the current switching states of the first and second safety switches. The PLC interrupts a main energy supply to the drive unit in response to the safety critical status of the elevator. Comparing switching states of the safety switches connected to the first and second connectors also enables detecting faulty safety switches.
