Definitions

  • the present invention relates to a climbing device for a tower crane, with a movable along the crane tower climbing frame for climbing and / or climbing off tower pieces, with a guide for longitudinally movable supporting the climbing frame is provided opposite the crane tower.
  • Tower cranes are usually adapted to the increasing height of the structure by installing additional tower sections. This process is commonly referred to as climbing.
  • the crane top which may comprise a crane boom, detached from the top tower piece and held by a climbing frame, which is mounted axially displaceable on the crane tower. After loosening the connection of the crane shell from the top tower section of said climbing frame is moved far enough that between the dissolved crane shell and the top tower piece another tower piece can be fitted, then dropped off the crane top or another tower section after a second climbing up can be.
  • Said climbing frame can surround the crane tower on the outside in the manner of a sliding sleeve and have a lateral insertion opening through which another tower section can be inserted or taken out again when climbing.
  • said climbing frame is mounted longitudinally displaceable on the crane tower or its tower sections.
  • the climbing frame In order to support the mounted during climbing and climbing temporarily only on the climbing frame crane top together with boom and record appropriate tilt and bending moments, the climbing frame by means of a guide on the crane tower, although longitudinally displaceable, but supported tilt stability. Such tilting moments can arise on the one hand by wind loads, on the other hand, for example. But also by receiving and releasing of climbing andinkletternden tower pieces that can be opened and lowered by the lifting means on the crane itself.
  • the longitudinally displaceable guidance of the climbing frame on the crane tower can in this case include transverse support elements, for example in the form of sliding plates, which, for example, can be attached to the climbing frame and can encompass the crane tower from different sides.
  • sliding plates can engage the longitudinal or corner posts of the tower sections, which are usually designed as truss girders, in order to guide the climbing frame longitudinally displaceable but tilt-stable on the crane tower.
  • guide rollers can also be provided on the climbing frame, which, for example, can roll on the said corner posts of the tower sections.
