  • 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: 20240017964
    Abstract: The arrangement comprises a hoisting machinery, an electric cabinet, and cable drums positioned at the bottom of the shaft, an elevator car and a counterweight moving in the shaft, upper pulleys and rope suspenders fixed at an upper end of the lifting height of the construction elevator, and hoisting ropes being fixed to the rope suspenders during the operation of the construction elevator and gliding through the rope suspenders during an upwards jump of the construction elevator in the shaft. The hoisting ropes pass in a 2:1 roping between the car, the upper pulleys, the traction sheave, the counterweight, and the rope suspenders.

  • 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.

  • Publication number: 20230192447
    Abstract: The installation platform comprises two decks and a support frame comprising horizontal support beams supporting a respective deck and vertical support beams. The installation platform has a width in a first horizontal direction between the guide rails, a depth in a second horizontal direction perpendicular to the first horizontal direction. The installation platform is guided movably via guide means on the guide rails. At least one of the width and the depth of the installation is adjustable in order to adjust the horizontal dimensions of the installation platform according to the horizontal dimensions of the shaft.
