A passenger is identified in connection with giving a call on the basis of the ID number of an identifier. The favorite floor list is updated on the basis of calls given by the passenger and/or a given updating criterion.

Abstract: A method for modernizing a hydraulic elevator including an elevator car guided by car guide rails for moving in an essentially vertical direction in the elevator hoistway, a hydraulic system including a lifting cylinder having a cylinder part essentially vertically supported on the base of the elevator hoistway and a piston rod moving in relation to the cylinder part and a hydraulic powerpack and a control center. The hydraulic system of the hydraulic elevator is modernized to include a function for preventing unintended starting at a floor, in such a way that the hydraulic powerpack is retained and an electrically-operating valve that is monitored with a control and that acts on the flow of hydraulic fluid of the lifting cylinder is added to the hydraulic system. The control controls a valve to prevent movement of the piston rod of the lifting cylinder downwards and/or upwards, if predetermined criteria are fulfilled.

Abstract: An elevator including one or more hoisting members that are continuous in the vertical direction, a load-receiving part suspended on the hoisting member, and also a driving member engaging with the hoisting member for moving the load-receiving part. The driving member engaging with the hoisting member is configured to be driven with a detachable drive unit.

Abstract: The invention refers to an Elevator door arrangement having at least one door leaf comprising a support structure and at least one door panel having a back part facing away from the public and a front part facing the public, which door panel is supported in the support structure of the door leaf. The door panel is configured to be supported in the support structure either with its back part or front part facing the public, as desired. This invention allows a protected use of a door panel during construction time use.

Abstract: An elevator, more particularly an elevator for passenger transport and/or freight transport, which elevator includes an elevator car, is arranged to travel in an elevator hoistway. Above the elevator hoistway is a space bounded by a floor, a counterweight, a first suspension roping and a second suspension roping, which suspension ropings connect the aforementioned elevator car and counterweight to each other, a mechanism configured to move the first suspension roping and the second suspension roping, one or more diverting pulleys of the first suspension roping disposed in said space, one or more diverting pulleys of the second suspension roping disposed in said space, and in which elevator the first suspension roping and the second suspension roping travel on vertical planes parallel to each other.
