Definitions

  • the invention relates to a device for storing a rope for a descending device.
  • the invention further relates to an arrangement comprising the above device and a descending device.
  • the invention also relates to the use of the above arrangement.
  • rope access techniques can be used, in which a worker, also known as a height worker, rappels down to the work site.
  • Height workers are typically used when it is either too expensive or too inconvenient to set up a crane or scaffolding to gain access to the work site. For example, height workers clean windows on high-rise buildings or carry out assembly, maintenance and repair work on wind turbines.
  • a descender In order to descend as reliably as possible from a higher work location to the ground in emergency situations, descending devices, also known as abseiling devices, can be kept at the work location.
  • a descender is a device with which a user can reach from a higher to a lower position safely and under planned load on a rope of the descender by the descender braking the passing rope.
  • the EP 2 512 605 B1 a rappelling device with a housing through which a rope is passed over a distance, with almost no force being exerted on the rope in a load-free position.
  • the abseiling device has a through opening in which a load to be abseiled can be attached, with one the ends of the rope are attached to the starting point of the abseiling process and the load is moved down along the rope together with the abseiling device.
  • descending devices are not only relevant for planned work assignments by workers at height, but are also used in the areas of (occupational) safety and rescue. For example, if a firefighter or work platform operator is trapped in a fire, they must be able to rescue themselves quickly. Appropriate abseiling devices must always be carried in special work situations. It should also be noted that the length of the rope of the abseiling device carried determines the maximum height from which safe abseiling is possible. Particularly for operations at very high altitudes, for example 150 m and more, the abseiling devices are correspondingly large, heavy and unwieldy. Since the abseiling devices are carried on the user's body, there is a need to provide abseiling devices that are as small and light as possible.
  • the object is achieved by a device for storing a rope for a descending device, the device comprising the rope, a rope drum and a dimensionally stable rope bag, the rope having a diameter of less than or equal to 8 mm, and being at least partially wound on the rope drum , such that a first end of the rope can be unrolled from the rope drum, and the rope drum is arranged in the rope pocket, such that the first end of the rope can be led out of an opening in the rope pocket.
  • the object is achieved by an arrangement comprising the above device and a descending device, the descending device comprising a centrifugal brake designed in such a way that a rope running through the descending device can be slowed down while running, and the rope of the device is guided through the descending device.
  • the rope has a diameter of less than or equal to 8 mm and is at least partially wound on the rope drum arranged in the rope pocket. Preferably, at least 3 ⁇ 4 of the rope is wound on the rope drum and particularly preferably essentially completely.
  • Devices and/or arrangements known in the prior art, comprising the device and the abseiling device for long abseiling distances, are large, heavy and unwieldy due to the long rope required for this, so that they cannot be carried on the user's body or can only be carried with great effort. It has unexpectedly been shown that reducing the diameter of the rope leads to the rope held in the rope bag becoming tangled and/or knotted during abseiling, which makes abseiling impossible or highly unsafe.
  • Winding the rope at least partially around the rope drum and arranging the rope drum in the dimensionally stable rope bag reduces the risk of knots forming in the rope or the rope becoming tangled when the rope is pulled out of the rope bag during abseiling, thus enabling safe abseiling also for long abseiling routes.
  • the rope is wound on the rope drum in such a way that the first end of the rope can be unrolled from the rope drum.
  • the rope can be unrolled from the rope drum by pulling on the first end. Since the first end of the rope is preferably used to attach to an anchor point when abseiling, the rope carried in the rope bag is unrolled from the rope drum during abseiling.
  • the cable drum is preferably mounted without a connection in the dimensionally stable cable bag, which in the present case means that the cable drum is not mechanically connected to the cable bag, for example by a screw connection, but is movable with a certain amount of play relative to the cable bag.
  • the freedom of movement of the rope drum in the rope bag is preferably limited by the inner dimensions of the rope bag. Storing the rope drum in this way and winding the rope on the rope drum preferably ensures that the rope flows undisturbed when abseiling, so that the safety of the user is guaranteed despite the small diameter of the rope.
  • the small diameter of the rope makes it possible to provide a very light and small device for storing the rope and/or a very light and small arrangement comprising the device and the abseiling device, in particular for long abseiling routes.
  • a dimensionally stable rope bag means that the rope bag essentially retains its shape even when unfilled and does not collapse due to the rope bag's own weight.
  • the rope bag is preferably not designed as a plastic bag, bag made of plastic film and/or polybag, and preferably does not have completely flaccid and completely deformable properties.
  • the rope bag is designed as a rope bag that can be slipped over the rope drum and/or removed from the rope drum.
  • the diameter of the rope is 8 mm or less than 8 mm, and preferably less than 8 mm. More preferably, the rope has a diameter of less than or equal to 6.5 mm and particularly preferably less than or equal to 6 mm.

More preferably, the rope has a diameter of less than or equal to 4.5 mm and particularly preferably less than or equal to 4 mm. These rope diameters have proven to be particularly suitable, on the one hand, to meet the mechanical requirements and/or loads of abseiling and also to be able to provide a lightweight device and/or a lightweight arrangement comprising the device and the abseiling device. For example, the device allows an arrangement with 200 m of rope to weigh less than 6 kg.
