Definitions

  • the buffers are pre-assembled and are required when the elevator system is in operation.
  • the space thus created between the floor of the elevator shaft and the elevator car is so small that it is not sufficient for a safety space during the installation of the elevator system.
  • a shaft module is placed on a pit element to form an elevator shaft of the elevator system.
  • a cabin of the elevator system is arranged in the shaft module.
  • a safety element is arranged in the shaft module or in the pit element in such a way that it limits a downward displacement of the cabin if the cabin comes to rest on the safety element during the downward displacement.
  • the safety element is arranged in such a way that the safety space is high enough for an installer to be able to stay safely in it and also carry out installation steps from the safety space. With the cabin resting on the safety element, a positive and therefore particularly secure connection is created between the cabin and the safety element, which reliably prevents the cabin from penetrating the safety space.
  • the at least one safety element is removed when the lift system is installed to such an extent that the car is held by a support means and buffers are arranged at the bottom of the pit element.
  • the buffers then ensure an appropriate safety space. If the safety space is provided by other devices after the lift system has been put into operation, for example by using extendable bolts on the cabin, at least one safety element shall be removed, in particular when the said device has been put into operation.
  • directional information such as up, down and sideways or vertical and horizontal refers to the orientation of the respective component in an operating state of the elevator system.
  • the operating state of the elevator system is understood to be the state after installation has been completed and the elevator system has been put into operation.

  • the pit element on which the basic module is placed encloses a shaft space, which contains the aforementioned safety space if required.
  • the aforementioned shaft space is in particular a little higher than the safety space.
  • the pit element can, but does not have to, have a shaft opening.

  • the downward movement of the cabin limited by the safety element can take place while the shaft module is being placed on the pit element.
  • the movement of the cabin therefore takes place together with the movement of the shaft module; in particular, there is no movement of the cabin relative to the shaft module.
  • the joint movement of the cabin and shaft module ends as soon as the cabin rests on the safety element. If the shaft module is not yet resting on the pit element, a relative movement of the cabin relative to the shaft module begins. This continues until the shaft module rests on the pit element.
  • the downward movement of the cabin limited by the safety element takes place after the shaft module has been placed on the pit element.
  • the shaft module with the cabin is first placed on the pit element placed on top and then the cabin is moved downwards and thus relative to the shaft module and the pit element until it rests on the safety element.
  • the cabin is held in particular by the crane used to stack the shaft modules.
