Embodiments are presented, inter alia, where the adjusting can be carried out quickly. Embodiments are presented, inter alia, where the adjustment result is optimal for the final configuration of the elevator.
  • the elevator car is formed to comprise a floor comprising a sandwich element comprising an upper plate and a lower plate parallel with each other and a plurality of adjacent inside spaces separated by core walls extending between the upper and lower plate, and in the method the weight of the elevator car and/or the balance thereof is adjusted by adding ballast material to form a part of elevator car.
  • the weight of the car and/or the balance thereof is adjusted by adding ballast material into at least some of said inside spaces.
  • the car weight and/or the balance thereof can be adjusted accurately and space-efficiently.
  • a rigid floor structure is achieved.
  • the inside spaces become utilized, which facilitates space-efficiency of the elevator.
  • the adjacent inside spaces allow the car balance to be adjusted by controlling the distribution of the added weight by adding ballast weight selectively to only some of the inside spaces and/or by adding different amounts of ballast weight to the inside spaces.
  • the ballast material is added in fluid form. In this way the amount of the ballast material as well as the distribution thereof can be more freely and accurately adjusted. Also, this enables efficient way to add the ballast material, as it can be done by pumping.
  • the weight of the car and/or the balance thereof is adjusted in the defined manner while the elevator car is in the hoistway. In this way, the adjustment is performed according to the final environment, and can be used to compensate for inaccuracies in installation of other elevator components.
  • the balance of the car is adjusted in the defined manner by adding substantially different amounts of ballast material into the inside spaces. This enables adjusting the weight distribution accurately.
  • the weight of the car and/or the balance thereof is adjusted in the defined manner while the elevator car is in the hoistway and suspended by the elevator ropes. In this way, the adjustment is performed according to the actual suspension, and can be used to finetune the properties to fit accurately for the suspension.

  • the drive machine comprises a motor M and a traction sheave 2, which engages elevator ropes 3, which ropes 3 are connected to the elevator car 1.
  • driving force can be transmitted from the motor M to the car 1 via the traction sheave 2 and the ropes 3.

  • Figure 1 illustrates the cross section of the elevator car 1.
  • an elevator car 1 as illustrated in Figure 1 is installed in the hoistway S to move up and down.
  • an elevator car as illustrated in Figure 1 is manufactured.
  • the elevator car is manufactured with a method wherein the elevator car is formed to comprise a floor F comprising a horizontally planar sandwich element 4, a ceiling, walls and at least one door these all forming together an interior space for receiving a load to be transported.
  • the construction of the sandwich element 4 is further illustrated in Figures 2 and 3 .

  • the ballast material 9 forms a filler material for said inside spaces 7.
  • the inside spaces become utilized, which facilitates space-efficiency of the elevator. In this way, for example, a great amount of weight elements need not be mounted on the bottom of the elevator car 1. This will allow the car floor structure to be more compact and the hoistway pit can be made shallow (i.e. reduced pit).
  • the adjacent inside spaces 7 allow the car balance to be adjusted by controlling the distribution of the added weight by adding ballast weight selectively to only some of the inside spaces 7 and/or by adding different amounts of ballast weight to the inside spaces 7.

  • the balance in particular can be adjusted such that the effect of the suspension is present.
  • the elevator can be finetuned to be very accurately balanced in its final environment. It should be appreciated that it is not necessary that the elevator car 1 is balanced to have a mass center in the center of the vertical projection but the location of the desired mass center depends on the suspension point, and even the position of the guide rails.
  • the elevator car comprises the sandwich element 4 as described and illustrated in Figures 2 an 3. Accordingly, it comprises a plurality of inlets 10 each leading to one of the inside spaces 7. It is illustrated a step where through one of said inlets 10 ballast material 9 is being guided to pass into the inside space 7.
