Definitions

  • the invention relates to a method for transporting Lattice boom cranes including counterweights according to the The preamble of claim 1 and a device for Performing this procedure.
  • a mobile crane is described in DE-AS 1 279 904, whose lattice boom is composed of spacers which have a rectangular cross section, which is along the longitudinal axis from the foot area to the head area of the Cantilever continuously tapered. Therefore, individual Slide spacers into one another for transport Achieve volume reduction. For intermediate pieces that this is a constant cross-section not possible.
  • a tower crane is known from DE-GM 1 937 030, whose tower is composed of intermediate pieces, the are each formed from elbows that releasably connected and in the same number are present like the sides of the tower, each Flat leg of an elbow has a width that the Half of the width of the tower side corresponds. in the disassembled state the contra-angles Stack into each other to save space. This is at Intermediate pieces, which form a solid structural unit, not possible.
  • This document also mentions that in Inside the construction space that the collapsed tower forms also other crane parts such as a crane ladder can be. This corresponds to that mentioned at the beginning Procedure, smaller intermediate pieces of a jib to be inserted into larger intermediate pieces of a main boom.
  • the object of the invention is to provide a method for transporting Specify lattice boom cranes, regardless of which Training of an auxiliary boom as well as a dismantling and a constant cross-section of the respective Boom spacers the required number of Transport movements can be significantly reduced.
  • lattice mast elements of Boom for the transport of counterweight elements used for the transport of counterweight elements used, the counterweight elements in or on the each lattice mast element are secured in place.
  • the attachment can be frictional; however, it is preferred form-fitting.
  • a device is used to implement the method a counterweight element and one as a lattice mast element trained intermediate piece proposed to the End faces with at least one attachment point provided connecting element and thereby is characterized in that at least one counterweight element can be secured in position or on the intermediate piece.
  • Counterweight element with the inside of the side wall of the Connecting piece. This is done on the inside a mounting frame arranged as a guide and in this the counterweight element inserted and secured.
  • the It can be inserted either from above, from the side or from from the front.
  • a backup is by means of Bolts, straps, chain, screws or clamps possible.
  • the Mounting frame is preferably made of sheet metal profiles composed, depending on the direction of insertion of the Weight element one up, to the side or to the Form an open U towards the front.
  • the Fastening frame composed of angle plates and form an L.
  • a less preferred method is that Counterweight element from the end face of the intermediate piece to lay on the inside of the lower chord side, whereby the Dead weight forms part of the positional security system an additional attachment is added.
  • Figure 1 shows a perspective view of a well-known intermediate piece prepared for transport 1 in lattice mast construction. It's rectangular in cross section, in particular square and points in this Embodiment an upper chord side 2, a lower chord side 3 and two side walls 4,4 '.
  • the end areas of the Intermediate piece 1 are here with two or three Fastening points 5, 5 ', 6-6 " Provide fasteners.
  • intermediate piece 1 is already for transport prepared when the corresponding guy rods 7 already are stored on the upper side 2.
  • Figure 2 also shows a perspective view a stack designed according to the invention Counterweight elements 8.9. Both counterweight elements 8.9 are in the four corner areas, each with an attachment point 10-10 '' ', 11-11' ''. In addition, everyone is Counterweight element 8.9 on two opposite sides at least one eyelet 12-12 ", 13-13" arranged to the counterweight element 8.9 regardless of the Attach attachment points 10-10 ", 11-11" to a hoist to be able to.
  • the first step is a counterweight plate 8.9 using the lifting eyes 12-12 ", 13-13" in the End region of the intermediate piece 1 filed.
  • the filing takes place in such a way that the Attachment points 10.10 'of the intermediate piece Counterweight element 8 between the two Fastening points 5.5 'of the intermediate piece 1 inserted become.
  • the two inner ropes 14, 14 'loosened and the two below lying bolts 15, 15 ' In Figure 4, the Steps 3 and 4 shown.
  • FIG 5 is also a perspective Representation of a less preferred attachment of Counterweight elements 17, 17 'in an intermediate piece 1 shown.
  • the attachment is made here that the respective counterweight 17.17 'on the inside of the Lower belt side 3 of the intermediate piece 1 deposited and through his own weight and one not shown Attachment to the adapter 1 in its position for the Transport is secured immovably.
  • the disadvantage is that there is a need for special lifting equipment in order to Counterweight element 17,17 'from the front of the To be able to insert intermediate piece 1 inwards.
  • FIG. 6 A preferred alternative to this is shown in FIG. 6.
  • 4.4 'of the on each side wall Intermediate piece 1 a mounting frame 18, 18 'each arranged.
  • the details of this are shown in FIG. 7.
  • the Mounting frame 18, 18 ' is in this embodiment designed so that the respective counterweight element 17, 17 'from above into the mounting frame 18, 18' can be inserted and secured.
  • FIG. 8 shows a stack example for a counterbalance wagon and Figure 9 shows a stack example of a base support plate of a lattice boom crane.
  • the reference symbols used therein correspond to those of the other figures.
