Definitions

  • the present invention relates to a stacking device for lattice boom crane elements, in particular for jib sections of a crane.
  • the aim of the present task is to create a stacking device that allows stacking of lattice boom crane elements of different diameters, which leads to a further reduction of the storage area when storing cranes of different types or when storing a crane with elements that have different diameters.
  • the stacking device for lattice boom crane elements in particular for jib sections, comprises a first support body, a profile rail, and a second support body, with the first support body having a concave, continuous trough on its bottom surface in order to accommodate or hold a longitudinal beam of a lattice boom crane element to be supported there, and on its top surface opposite to the bottom surface has a coupling section for displaceable attachment to the profile rail, and the second support body has a concave continuous trough on its top surface in order to accommodate a longitudinal beam of a lattice boom crane element, and on its bottom surface opposite to the top surface has a coupling section for displaceable attachment to the profile rail.
  • the first support body can be arranged on a lattice mast crane element arranged on the ground, for example a jib section of a crane.
  • the concave trough (i.e. a trough that runs to the inside of the first support body) of the first lattice boom crane element is placed on a longitudinal beam of the lattice boom crane element arranged on the ground, so that the top surface of the first support body protrudes upwards.
  • This ceiling surface is coupled via its coupling section with the rail, usually in such a way that the first support body only along the Can be moved longitudinally of the rail.
  • the second support body is in contact with the profile rail in a similar way.
  • the coupling section is arranged on the profile rail in such a way that, as a rule, only a displacement movement in the longitudinal direction of the profile rail is possible.
  • a concave trough for accommodating a longitudinal beam of a lattice boom crane element is then in turn provided on the top surface of the second support body facing away from the profile rail.
  • the concave trough is an arcuate contour extending toward the interior of the second pad body and extending continuously throughout the body. It is advantageous if the trough of the first support body is essentially identical or identical to the trough of the second support body.
  • the (upper) second support body can simply be moved along the profile rail in a corresponding manner, so that stacking a such element different in cross-sectional diameter is possible.
  • the rail consists of aluminum.
  • the profile rail to have an essentially rectangular, preferably essentially square, basic structure in its cross section.
  • the coupling section of the first support body and the coupling section of the second support body each have engagement elements for engaging behind a profile of the profile rail.
  • the respective support body engages in an associated profile of the profile rail, so that the support body can only be moved along the longitudinal direction of the profile rail.
  • the support bodies are thus pushed onto the profile rail.
  • first support body and the second support body can be fastened to the profile rail at the same time, with different profiles of the profile rail preferably being provided for this purpose.
  • These profiles are preferably on opposite sides of the rail.
  • the longitudinal direction of the profile rail is preferably arranged transversely to the direction of the trough of the support body.
  • the profile rail thus runs transversely to a longitudinal beam of the lattice boom crane element that is placed in the trough.
  • first support body and/or the second support body is/are made of a plastic, a composite material, an elastomer and/or a rubber.
  • the second support body has, in its trough arranged in the top surface, a groove running on a trough base in order to drain off water that collects in the trough when a longitudinal member is picked up.
  • a further groove running in the trough is provided in the lower area of the trough, in order to be able to drain off any water that collects there.
  • the coupling section of the first support body is identical to the coupling section of the second support body.
  • the coupling section of the first support body and/or the second support body has engagement hooks for engaging in a profile of the profile rail.
  • the distance from the bottom surface to the top surface of the at least one first support body is preferably greater than the distance from the bottom surface to the top surface of the at least one second support body, preferably at least twice as large, preferably at least three times as large.
  • At least two first support bodies, a profile rail and at least two second support bodies are provided, the at least two first support bodies and the at least two second support bodies being arranged on the same profile rail via their respective coupling section.
  • the at least two first support bodies are arranged on a first side of the profile rail and the at least two second support bodies are arranged on a second side of the profile rail.
  • the at least two first support bodies are each introduced into one and the same first profile of the profile rail and the at least two second support bodies are each introduced into one and the same second profile of the profile rail.
  • the stacking device 1 shows a representation of the stacking device 1 according to the invention together with a lattice boom crane element 2 in a side view.
  • the stacking device 1 is on the side facing away from the ground Lattice boom crane element 2 arranged so that more lattice boom crane elements can be stacked.
  • the stacking device 1 according to the invention is provided on the upper side of the lattice boom crane element 2, for example a boom section of a lattice boom crane.
  • This comprises two first support bodies 3, which each interact with different longitudinal beams 25 of the lattice boom crane element 2 running parallel to one another. Both of the first support bodies 3 are connected to a profile rail 4, on the upper side of which at least two second support bodies 5 are arranged.
  • first support bodies 3 can be designed differently from the second support bodies 5 . These can be longer in the height direction, so that the profile rail 4 running transversely does not collide with add-on parts of the lattice boom crane element 4, in this case a retaining rod 24.
  • FIG. 2 shows a representation of several stacking devices 1 according to the invention together with several stacked lattice boom crane elements 21, 22, 23 of different diameters in a side view.
  • the present invention it is also possible to stack lattice boom crane elements 21, 22, 23 of different diameters.
  • the respective support bodies 3, 5 are simply pushed along the profile rail 4 until they are arranged at the appropriate point for receiving a longitudinal beam of a lattice boom crane element 21, 22, 23.
  • the advantage of the invention is that the support bodies 3, 5 arranged on the opposite side of the profile rail 4 can be displaced independently of one another along the longitudinal direction of the profile rail 4.
  • the figs 3a and 3b show a view of the transverse and the longitudinal side of the stacking device 1 according to the invention in a non-assembled state.
  • Figure 3a one recognizes the profile rail 4 in a cross-sectional view, so that one can see the indentations 41 which form the profile of the profile rail.
  • the two coupling sections 32, 52 of the support bodies 3, 5 are each provided with engagement hooks 321, 521, which are designed to engage in corresponding indentations 41 of the profile rail 4 in such a way that the support bodies 3, 5 are only moved along the longitudinal direction of the profile rail 4 be able. A movement deviating from this is not possible due to the engagement of the engagement hooks 321, 521 in indentations 41 provided for this purpose.
  • the coupling section 32, 52 can form an undercut together with the respective engagement hooks 321, 521, so that the support bodies 3, 5 have to be pushed onto the profile rail 4.
  • Figure 3b shows a longitudinal side of the profile rail 4 and correspondingly aligned support bodies 3, 5. It can be seen that the troughs 31, 51 of the support bodies 3, 5 run transversely to the longitudinal direction of the profile rail 4 and are used to insert a longitudinal beam 25 of a lattice boom crane element 2.
  • the base of the trough of the second support body 5 has a groove 512 in order to be able to drain off any water that may have accumulated in the trough 51 .
  • such a groove can also be provided in the trough 31 of the first support body 3 .
