  • the invention relates to an elevator and to mounting of the guide rails thereof.
  • the elevator is particularly meant for transporting passengers and/or goods.
  • Elevators have an elevator car moving in a vertical hoistway.
  • elevators usually have a counterweight connected to the elevator car and moving in the hoistway.
  • These elevator units are each guided with at least one guide rail line located in the hoistway.
  • each guide rail line has plurality of vertically oriented guide rail sections placed end-to-end on top of each other.
