Definitions

  • the present invention relates to a device for mounting elements such as a roof light in an exterior construction in a building, where the device comprises:
  • the present invention also relates to the application of this device.
  • a guiding rail can be mounted a point above the window opening, on which there is placed a so-called crane crab or hoisting device, which can be used to lift the window up in place in the frame.
  • JP 5138557 A describes a different hoisting device, which can be placed on the guiding rail.
  • the hoisting device it is necessary to initially raise a scaffold on each side or end wall of the building, whereafter the guiding rail and the hoisting device can be mounted.
  • the guiding rail can be mounted on a frame, which is placed above the opening. The use of such hoisting devices contributes to complicate and raise the costs of the mounting process since it requires a lot of preparatory work before the window can be mounted.
  • CN 201753244 U describes a portable hoisting crane comprising a first telescopic rod with abutting surfaces in both ends, a crane arm connected, in a tiltable way, to the telescopic rod and another telescopic rod connected to the crane arm and with an abutting surface in the bottom.
  • the crane arm is connected to an electrically operated hoist, such that the hoisting crane can be operated by one person.
  • the first telescopic rod is fixed to floor and ceiling where the other telescopic rod is used to adjust the angle of the crane arm.
