  • the mounting means 31 could alternatively be in the form of gripping means arranged to grip a guide rail mounted in the hoistway, such as an actuatable safety gear or an actuatable friction pad caliper brake, for instance.
  • the hoisting is prepared such that the method comprises before said hoisting the movable support structure 30 actuating said releasable mounting means 31 to release mounting of the movable support structure 30.
  • the hoisting is illustrated, and at this phase, the releasable mounting means 31 have been actuated to release mounting of the movable support structure 30 (in this case retracted towards the center of the hoistway 2).
  • the hoisting can be performed in different ways.
  • the hoisting is performed with a hoisting arrangement 50 mounted above the movable support structure 30.
  • the hoisting arrangement comprises a support structure 51 as well as a hoist 52 and a roping 53 supported by support structure 51.
  • the hoist 52 is arranged to pull the support structure 31 upwards powered by the hoist 52.
  • the hoisting arrangement could be any known type.
  • the hoisting arrangement can be an integral part of the movable support structure 30, such that the support structure can perform self-climbing movement in the hoistway 2 in which case the hoisting arrangement would be mounted on the movable support structure 30 and comprise an up and down movable support structure.
  • the method comprises after said hoisting the movable support structure 30 actuating said releasable mounting means to mount the support structure 30 stationary in the hoistway 2. This is illustrated in Figure 7 , where the releasable mounting means 31 have been actuated to mount the support structure (30) stationary in the hoistway 2 (in this case to extend on top of a support face f).
  • the method comprises before or during said hoisting opening a rope clamp 43 and feeding rope via the rope clamp 43 into the roping 3 from a rope storage 42, as illustrated in Figure 6 .
  • the method comprises, before said first using, connecting a terminal 16;26 of the cable 12;22 to a terminal 100a connected to or comprised in the control system 100 of the elevator for establishing a connection, preferably an electrically conductive connection, between the cable 12;22 and the control system 100 as illustrated in Figure 8 .
  • the method can, although this is not necessary, comprise before said second discharging disconnecting the terminal 26 from a terminal connected with or comprised in the control system 100 of the elevator, and after said second discharging reconnecting the terminal 26 to a terminal 100a connected to or comprised in the control system 100 of the elevator. This facilitates particularly use of embodiment illustrated in Figure 2 where rotation of components is involved in discharging.
  • the method can, although this is not necessary, comprise maintaining, during said second discharging, the terminal 16 connected to a terminal 100a connected to or comprised in the control system 100 of the elevator for maintaining a connection, preferably an electrically conductive connection, between the cable 12;22 and the control system 100.
  • a connection preferably an electrically conductive connection
  • each said using the elevator car 1 for transporting passengers and/or goods comprises automatically operating, in particular by an elevator control system 100, a machinery 4, to move the elevator car 1 between vertically displaced landings F0,Fn, in particular in response to signals received from one or more interfaces 200, such as one or more user interfaces operable by a user.
  • Each discharging preferably comprises when the cable storage unit 10 is in accordance with the embodiment illustrated in Figure 1 pulling or allowing gravity to pull cable 12 bent by folding out from said storage space 11.
  • Each discharging preferably comprises when the car cable storage unit 20 is in accordance with the embodiment illustrated in Figure 2 rotating or allowing rotation of the said first and second cable wheels 28,29.
  • car cable storage unit 10,20 as defined provides that the car cable storage unit 10,20 can be positioned relatively freely to a desired position in cross-section of the hoistway 2. Due to shape and formation achieved being relatively high the car cable storage unit 10,20 can be made even so thin in thickness and width direction that it fits to be positioned between counterweight guide rails effectively. Accordingly, in a further embodiment the car cable storage unit 10,20 is positioned between two guide rails adjacent a hoistway wall.
