  • Publication number: 20240067504
    Abstract: This invention relates to a method of monitoring assembly of an elevator, comprising prefabricating a plurality of hoistway sections each hoistway section having a hoistway space, transporting the hoistway sections to a building site, and lifting the hoistway sections at the building site on top of each other. In order to facilitate fast and reliable assembly, a hoistway section is provided during prefabrication with a sensor device having a transmitter which is activating during prefabrication to transmit sensor data via to a data storage storing the transmitted sensor data in a memory. The sensor data is monitored, and transmission of a message to a predetermined recipient is triggered when the sensor data fulfills at least one predetermined criterion defined in an assembly plan.

  • Publication number: 20230373755
    Abstract: The invention relates to an elevator, comprising a hoistway with a plurality of hoistway sections attached to each other to provide a hoistway with a hoistway space, an elevator car arranged in the hoistway space to be vertically movable in the hoistway space between door openings at landings of a building, and doors at the door openings. In order to avoid problems caused by a mutual change of height of a hoistway and a building, a sensor provides to a control system a signal indicating a level difference between a first reference point of the hoistway and a second reference point of the building.
