Definitions

  • a ballast is secured [30] Fomlgn Apphcamn Pnomy Dam on a frame which is pivoted on the rotatable frame of the Jan. 14, 1970 France ..7001162 crane about a vertical axis but which can be immobilized in the rotational direction relatively to this rotating frame.
  • U-S. Coupling means are fixed or may be fixed on the lower frame [5]] lint. Cl.
  • Transportable tower cranes which comprise a lower frame, the angular position of which is stationary when the crane is working and which is associated with supporting or stabilizing elements; an upper frame which can rotate on this stationary frame, generally through the intermediary of a slewing ring; a tower or a mast comprising one or several elements which can be collapsed on to the rotatable upper frame for the purpose of transportation; and a jib connected to this mast.
  • One object of the invention is to provide a solution to this problem.
  • a transportable tower crane for rapid erection and of the above-mentioned kind, which comprises a lower stationary frame associated with supporting or stabilizing elements; an upper rotating frame; a mast made of one or more parts which can be collapsed on to this rotating frame and a foldable jib, the arrangement being such that these various elements are horizontally positioned for transportation, characterized in that there is provided a ballast secured to a frame which pivots on the rotating frame of the crane about a vertical axis but which can be angularly immobilized relatively to this rotating frame, there also being provided a beam or equivalent coupling means which is fixed or may be fixed on the stationary frame and is so disposed that it can be pivotally connected to a tractor vehicle about a vertical axis coincident with the vertical pivotal axis of the ballast-carrying frame on the rotating frame of the crane.
  • the ballast-carrying frame may be of any shape that pennits the above'mentioned pivotal movement and immobilization.
  • a possible arrangement consists in using a ballast-carrying frame of triangular form and one or more tie rods which enable it to be immobilized in the rotational direction during operation of the crane.
  • the coupling beam may also be of triangular form.
  • Another object of the invention is to provide, for transportation purposes, at least one axle-tree which can be fitted below the collapsed parts of the crane, particularly of the mast, and members connected to the stationary frame of the crane to enable it to be lifted from the ground so as to enable the rear portion of the collapsed crane to be raised.
  • An arrangement of this kind enables this rear portion of the crane and particularly the ballast to be raised so as to position the platform or deck of a tractor vehicle, which may be of conven tional type, below the ballast so that the ballast rests on said platform for the purpose of transportation.
  • the lifting members connected to the fixed frame can be, for example, the jacks usually provided at the ends of the stabilizing arms associated with the stationary frame of the crane and normally used to ensure stability, or they may be one or more jacks specially provided for this purpose on the stationary frame, or they may be constituted by the erecting system itself adapted to suit this purpose.
  • FIG. I is a schematic side view of a tower crane in accordance with the invention and in the position for transportation.
  • FIG. 2 is a schematic partial plan view.
  • the numeral I designates the normal stationary lower frame of the crane which here is of square form and at the corners of which are pivoted stabilizing arms 2 which hold the crane in position when it is operating.
  • these arms are shown in solid lines in the position for transportation and in broken lines in the operating position.
  • the fixed frame 1 carries a slewing ring 3 which in turn supports the upper rotating frame 4 on which is pivoted the lower element 5 of the crane-mast which comprises an upper element 6.
  • the jib 7 is collapsed on to the folded elements of the mast.
  • the ballast 8 of the mast is secured on a frame 9, which, in the embodiment illustrated is of triangular form providing an apex and is pivoted at 10 on the rotating frame 4 through its apex about a vertical axis indicated by the numeral Ill.
  • the ballast-carrying frame 9 is immobilized relatively to the rotating frame 4 and coaxially therewith, by means of a tie rod I2.
  • the stationary frame 1 carries a beam 13 which, in the embodiment illustrated, is of triangular form having an apex and is so located and dimensioned that it can be attached at 14 through its apex to a tractor vehicle generally indicated by the reference numeral 15.
  • the attachment point 14 is located on the vertical axis 11 and can be seen in FIG. 1.
  • an axle-tree shown schematically at 16 in FIG. I, is fixed below the folded mast of the crane at a suitable distance which may range from 7 to 12 meters depending on the type of crane.
  • the folded assembly is raised by its rear portion.
  • This lifting movement can be achieved for example by means of the jacks shown schematically at 17 in FIG. 2 and normally provided at the ends of the arms 2 for the purpose of stabilizing the crane when it is operating; alternatively the lifting movement can be achieved by means of a central jack provided below the fixed frame and illustrated schematically at 18 in FIG. I, or by using the system for erecting the crane, in which case several different arrangements are possible.
  • the platform 19 of the tractor vehicle 15 is brought below the counterweight and the shaft 13 is attached at the point 14 to the tractor vehicle by lowering the counterweight 8 in such manner that it alone rests upon the platform 19.
  • the tie rod 12 is then removed so that the assembly is ready to be transported.
  • the ballast is supported by the tractor vehicle as is a portion of the weight of the crane through the intermediary of the pivot arrangement 10, and the assembly is pulled by the vehicle through the attachment hook and the beam 13.
  • pivot points 10 and I4 are located along the same vertical axis 11 so that when bends in the road are being negotiated, the assembly pivots around its vertical axis, the ballast 8 resting on the platform 19 of the vehicle without being displaced relatively thereto.
  • a transportable tower crane for rapid erection to be coupled to a tractor vehicle for transportation comprising a stationary lower frame, stabilizing elements provided on said stationary lower frame, an upper rotating frame, slewing means provided between said rotating frame and said stationary frame, a mast, means for collapsing said mast on said rotating frame, a foldable jib, whereby said mast and said jib are horizontally positioned for transportation, a ballast, a frame on which said ballast is secured, pivoting means for connecting said ballast-carrying frame to said rotating frame for pivotal movement about a first vertical axis, coupling means connectable to said stationary lower frame for coupling said crane to said tractor vehicle and means for pivotally connecting said coupling means with said tractor vehicle about a second vertical axis, said second vertical axis being coincident with said first vertical axis.
  • ballast-carrying frame has a triangular portion having an apex directed towards said rotating frame, said pivoting means connecting said apex of said triangular portion with said rotating frame and comprising tie rod means insertable between said ballastcarrying frame and said rotating frame for angularly immobilizing said ballast-carrying frame with respect to said rotating frame.
