An elevator includes at least one elevator shaft and at least one elevator car traveling in the elevator shaft. The elevator has at least one elevator motor including at least one linear stator located vertically along the elevator shaft and at least one mover located in connection with the elevator car and co-acting with the stator. The elevator includes a vertical stator beam supporting at least one stator, which stator beam has at least one side face carrying ferromagnetic poles of said stator spaced apart by a pitch. The mover includes at least one counter-face facing the side face(s) of the stator beam, in which electro-magnetic components of the mover are located.

The invention relates to a method for defining a tension of a belt of an automatic door. The method comprises: exciting a resonant frequency of the belt to cause a vibration of the belt, obtaining motion data representing motion of an electric motor configured to move the belt, defining vibration information representing the vibration of the belt based on the obtained motion data, and defining the tension of the belt based on the defined vibration in-formation and predefined characteristics of the belt. The invention relates also to a door drive unit and a computer program for defining a tension of a belt of an automatic door.

An elevator system and a support column assembly. The elevator system includes a support column, with the bottom end thereof connected to a bottom mounting base, and the top end thereof connected to a top mounting base; a counterweight arranged in the support column; a car having a through hole penetrating in a vertical direction, wherein the car is arranged around the support column via the through hole; and a traction assembly, wherein the car is connected to the counterweight via the traction assembly, and the car and the counterweight reciprocate along the length direction of the support column under the traction of the traction assembly.

A door system for an elevator installation having an elevator car with a car door arranged to travel in an elevator shaft with shaft doors, wherein the car door is spaced from the shaft doors in a closed position of the door system. A primary pivot spindle is coupled to a pivotable door leaf of the shaft door or the car door and a secondary pivot spindle is coupled to a pivotable door leaf of the other of the car door and the shaft door. A drive unit includes a driven, pivotably mounted shaft to which a first entrainer and a second entrainer are fixed. During a pivoting movement of the shaft, the first entrainer engages a first counterpart element on the primary pivot spindle and the second entrainer engages a second counterpart element on the secondary pivot spindle to effect a pivoting movement of the door leaves.
