Definitions

  • the invention relates to an arrangement and a method for constructing an elevator.
  • the elevator is preferably an elevator for transporting passengers and/or goods.
  • Such construction time elevators are known, hereinafter also referred to as jump-lifts, where the bottom part of an elevator hoistway is taken into use already when the upper parts of the building and the hoistway are still under construction or even non-existent.
  • the upper parts of the building as well as the top part of the elevator hoistway can be constructed at the same time as an elevator moving in the bottom part of the elevator hoistway already serves people on the lower floors of the building under construction.
  • the elevator car moving in the lower parts of the elevator hoistway is supported and moved during construction-time use with a hoisting machine supported on a machine room which is vertically movable in the elevator hoistway.
  • jump-lifts are known where the hoisting machine is supported on a guide rail.
  • construction of the upper part of the elevator shaft and installation of elevator components in the shaft can be a safety risk for the people and elevator components.
  • Objects, such as installation tools or construction parts can fall from the upper parts of the hoistway, and hit and damage people or elevator components located in the lower parts of the hoistway.
  • a protective cover in the hoistway, which covers substantially completely the cross section of the hoistway and is able to block falling objects.
  • the protective cover separates the hoistway to a lower portion and an upper portion.
  • An elevator car can safely operate and serve in the lower portion below the protective cover, while construction work can be safely performed in the upper portion above the protective cover.
  • prior art documents W02010010226 Al and WO202 1170847 Al different protective structures have been disclosed, for example.
  • the completed part of the elevator hoistway can be taken into use.
  • a "jump" is performed, wherein the hoisting machine is hoisted higher in the elevator hoistway.
  • the car can reach a higher position than before the jump and start to serve additional floors.
  • the protective cover is removed from its position as part of the jump. It can be placed e.g. above the hoisting machine in its new location so as to separate the hoistway again in two portions, if construction above the hoisting machine is to be done also when the hoisting machine is in its new position.
  • a drawback of prior art has also been that the car interior height has been standard, thereby not allowing transport of very long objects. Long objects have therefore been transported to floors by other means, such as via other special construction time elevators e.g. traveling along the building outer face, cranes or e.g. a hoist used in some other hoistway.
  • other means such as via other special construction time elevators e.g. traveling along the building outer face, cranes or e.g. a hoist used in some other hoistway.
