Definitions

  • the invention relates to a crane ballast system for lifting and applying of ballast elements as a counterweight to a crane or their removal from Crane.
  • the object of the present invention is to provide a crane ballast system, in which the ballast elements in a simple and straightforward way can be applied or removed, and in which reduces the risk of accidents is.
  • the crane ballast system according to the invention has at least one ballast element with at least one through opening. Furthermore, a mounting device provided, which comprises an elongated element, which by the at least one opening in the at least one ballast element inserted therethrough can be. In addition, the mounting device has a lifting device for Lifting up the entire mounting device. The opening in the at least a ballast element and the mounting device each have connecting devices for interlocking with each other.
  • the ballast elements simple and uncomplicated as a counterweight to put on or taken off.
  • By locking the mounting device in the ballast this is raised with and can on the crane as Counterweight are stored. Unlock the connection and pull out the Mounting device from the opening of the ballast element close the process from.
  • the Kranballast istssystem invention can be also for removing the ballast elements from the ballast stack or dismantling the crane.
  • ballast elements are provided, which are stacked on each other as a ballast stack and depending on the number of stacked elements a different Counterbalance. It is particularly easy to stack plate-shaped Ballast elements.
  • the particular advantages of the crane ballast system according to the invention occur especially when picking up ballast elements from a ballast element stack on.
  • z. B. when receiving ballast elements z. B. from a transport vehicle to hang up on the ballast stack as a counterweight on a crane or during dismantling of the crane for receiving the crane Ballast elements from the ballast pile of the crane for storage on a transport vehicle.
  • a simple embodiment of the lifting device for lifting the mounting device provides an eyelet in the z. B. engage a crane hook for lifting can.
  • Kranballast istssystems has the elongated element of the mounting device a preferably downwardly tapered centering on. Such Centering facilitates the precise placement of a ballast element the ballast pile.
  • the centering device be slidably mounted so that they are in the insertion of the mounting device in the opening is pushed together when the mounting device through the Opening to an object arranged underneath, z. B. the support base plate for the ballast elements abuts.
  • the lock between the mounting device and the opening of a ballast element can be realized in different ways. So z. B. appropriate Bolt be extended radially from the mounting device. Especially however, an embodiment is simple in which the opening in the at least a ballast element is not circular and the mounting device over a Counterpart has that in a position through this non-circular opening does not fit and in another position does not. For this the counterpart towers over the elongated one Element of the mounting device laterally and has an outer contour, which fits in a first position through the non-circular opening and in one second position not. It is provided that the first and the second position by twisting the elongate element about its longitudinal axis can be adjusted. After pushing through the elongated element through the opening, the rotation of the mounting device leads around the longitudinal axis the elongate member for locking the counterpart in the opening of the ballast element.
  • the mounting device at least one transverse pin extending from the elongated device extends laterally outward, wherein the at least one opening of the at least a ballast element has an insertion slot through which this cross bolt can be performed during insertion of the mounting device in the opening.
  • rotation of the mounting device leads to the Longitudinal axis of the elongated element for locking the transverse pin in the opening of the ballast element.
  • the embodiment is simple, e.g. B. by Pressing the transverse pin in the elongate element, produced.
  • the centering device a corresponding embodiment mounted on this cross bolt become. This forms an easy to install and cost effective solution.
  • the Centering has z. B. on an axially extending slot.
  • the opening in the at least a ballast element triangular designed and the connecting device to the Mounting device has z. B. on a triangular counterpart.
  • the mounting device with the counterpart by first passed through the triangular opening. Turn 60 ° around the longitudinal axis of the elongated element of the mounting device leads to the locking of the counterpart in the ballast element.
  • the ballast element has markings on its surface for indicating the locking position of the mounting device in the ballast element on. In this way it is easy to see when a secure lock is present and the ballast element to be lifted with the mounting device can.
  • the mounting device itself has a rotating device for rotation around its longitudinal axis. This can, for. B. from a fold-out lever which can be easily handled by an operator.
  • the elongate device of the mounting device has a such length that they not only an opening of a ballast element, but the Openings of several superimposed ballast elements can prevail. In this way it can be decided depending on the requirement, whether in one Operation one or more ballast elements raised or placed as a weight should be.
  • the elongated element can be moved and locked Stop, which can be adjusted so that it enters another prevents the mounting device in the overhead ballast element when the mounting device the desired length far into the stack of ballast elements occurred.
  • ballast elements are particularly favorable. Just when only a few are lifted from a ballast stack with several ballast elements or a number of ballast elements on an existing one Ballast stacks are to be stored, would be a downwardly projecting counterpart hinder. In a simple way, this can be done with downwardly open recesses realize at the openings.
  • ballast element It can be provided per ballast element a plurality of through openings, by the lifting of the ballast element a corresponding number of mounting devices is inserted through it. It is particularly advantageous if a Opening of the ballast element in its center of gravity, so usually central, is arranged so that only a single mounting device can be used got to.
  • ballast elements of a ballast stack can in an advantageous embodiment of the crane ballast system have grooves / wedges, lugs and / or recesses, which in corresponding counter-elements of another ballast element for lateral fixation can intervene.
  • a similar lateral fixation can be z. Belly achieve with opposing approaches.
  • Particularly easy to manufacture and easily rotatable in the openings is a cylindrical Mounting device or a tubular configuration, the z. Belly can serve to receive a centering element.
  • she comprises an elongated tubular element 11 with two radial bores, in which a transverse pin 7 is pressed.
  • cross bolt 7 hangs down tapered centering 37 in a slot 39, which is upwards extends into the tubular member 11 and the transverse pin 7 comprises.
  • the Centering element 37 can over the entire length of the slot 39 in the axial Direction of the elongated element 11 are moved.
  • At the upper end the elongated element 11 is an eyelet 9, in the z. B. a crane hook can be hung.
  • About the elongated element 11 is another Pipe 13 inverted, which has an approach 15.
  • On the tube 13 is a hinged lever 35 attached.
  • the tube 13 is connected to the elongated tube 11 with Help a bolt 17 can be fixed, which are inserted through openings can, hidden in the view of Figure 2 through the tube 13 and not so far are visible. In this way, the distance of the stop 15 of the Set cross bolt 7 at different heights.
