  • Patent number: 11548762
    Abstract: An elevator car includes a roof deck; a plurality of walls; a floor; one or more doors; and a transport space bordered by the roof deck, the plurality of walls, the floor, and at least one openable and closable door for allowing access to said transport space. The roof deck is vertically movable from a first normal use position upwards to a second cargo use position for increasing the height of the transport space, and from the second position downwards back to the first position for reducing the height of the transport space. An elevator and a method implementing the elevator car are also disclosed.

  • Publication number: 20210387832
    Abstract: The invention concerns a method, system and computer program for monitoring the run of a roping interconnecting a car and a counterweight of an elevator and for detecting an abnormal operation condition during the drive of a traction sheave intending therewith the car and the counterweight to be moved via said roping. Said roping is running on its way from the car to the traction sheave via at least one pulley and on its way from the counterweight to the traction sheave via at least one pulley, wherein the rotation of said at least two pulleys is monitored by sensing their rotation. These rotation data are then analysed in view of a mutual correlation indicating therewith a synchronized run of the roping on either side of the traction sheave, and detecting therewith an abnormal situation when detecting an absence of such correlation.
