Definitions

  • a crane disclosing the preamble of claim 1 is disclosed US3949882A described.
  • a tower crane having the features of claim 1. Accordingly, a tower crane is provided with a tower structure at the upper end of which a boom is arranged, wherein according to the invention at least part of the tower structure is formed by at least three parallel tower sections arranged next to one another.
  • the transition piece has an upwardly tapering conical shape and is preferably designed as a lattice element, as a tower piece or as a frame, for example as a sheet metal construction.
  • the transition piece connects the at least three parallel tower sections with a single tower section, with the individual tower section preferably being made wider than each of the parallel tower sections.
  • the at least three parallel tower sections represent independent crane towers or at least parts thereof which can be used in other tower cranes.
  • the broader individual tower section represents an independent crane tower or at least a part thereof which can be used in another tower crane.
  • the at least three parallel tower sections are connected to one another by stiffeners. This further increases the stability of the tower structure according to the invention. It can be provided that the individual tower pieces are connected to one another by cross braces, stiffeners, lattice pieces or other stiffening elements.
  • the tower crane 10 is designed as a top-slewing crane and has a tower structure 2, at the upper end of which a boom 8, consisting of a main boom and a counter-jib, is rotatably attached via a slewing gear.
  • the tower structure 2 has three sections.
  • the upper section which is connected to the jib 8, is formed by a single tower piece 7.
  • the lower section which is connected to the crane foundation 3 , is formed by four parallel tower pieces 1 arranged next to one another, each of which has a smaller width or outer circumference than the individual tower piece 7 .
  • the smaller tower sections 1 form the corners of a square and are connected via a conically shaped transition piece 6 (middle section) to the single wider one Tower section 7 connected. To increase stability, the smaller tower sections 1 are connected to one another by additional stiffeners 5.
  • FIG. 2a a section (top view) through the lower portion of the tower structure 2, indicated by the arrows marked "A", is shown. It can be seen that the four parallel tower sections 1 form the corners of a square, as a result of which high stability of the tower structure 2 is ensured.
  • the invention is based on the insight that several smaller tower sections 1 can enable a more stable crane tower configuration than a single, wider or stronger tower section 7.
  • smaller tower sections 1 of other crane systems are typically cheaper and more readily available on the market than larger crane towers 7.
  • Tower sections 1 of smaller crane systems unused kept ready and can thus be used easily and inexpensively in the tower structure 2 of a tower crane 10 according to the invention.
  • a tower system can be constructed which is stronger or more stable and, based on the price per meter, cheaper than a single, larger crane tower of the 1250 HC type. This makes it possible, for example, to provide free-standing Liebherr 550 / 630 / 1000 EC-H cranes with hook heights of over 100 m.
  • smaller tower sections of the 120 HC type for example, are more economical to assemble and more readily available on the market than larger tower sections of the 1250 HC type.
