Definitions

  • the re-shearing means can be actuated at least indirectly with a horizontal drive of a crane that is equipped with the re-shearing device, in particular if it can be moved from an initial position into a decoupling position, the re-shearing from the N-line operation to the M-line operation can be performed by uncoupling the top block from the breakpoint without a separate drive to actuate the reversing means.
  • the horizontal drive can be a drive of a trolley of the crane on which the reversing device is designed or arranged.
  • the reshearing device has a reshearing link in which the Breakpoint is formed.
  • the reversing link can be connected at least indirectly to a support structure, for example to the above-mentioned traverse or the above-mentioned jib of the crane.
  • the re-shear device in particular the previously mentioned re-shear link of the re-shear device, can have an upper dead center which is preferably arranged above the holding point and/or opposite the holding point.
  • the top block After reaching the top dead center, the top block can be lowered with the hoist to an intermediate position above the holding point until the load and/or the moment reaches a relief value below the previously mentioned limit value. When the load and/or moment reach(s) the unloading value below the limit, suggests that the intermediate position has been reached.
  • the top block can remain in this intermediate position for a defined period of time, for example by setting the crane hoist to stop. By stopping the top block in the intermediate position below top dead center, but above the stopping point, vibrations that can impair the engagement of the top block in the stopping point can initially be reduced. When the defined period of time has elapsed, the top block can then be lowered and the reversing bolt of the top block engaged in the holding point. The top block can be lowered from the intermediate position by a defined lifting distance, for example.
  • the re-shearing device 2 comprises a re-shear link 10 in which the holding point 7 is formed.
  • the re-shearing means 8 can be moved from an initial position into a decoupling position for re-shearing the crane 1 from 4-strand operation to 2-strand operation. This is done indirectly by a horizontal drive 27 of the crane 1 for a trolley 11 of the crane 1. In the uncoupling position, the reversing means 8 closes the breakpoint 7 for the reversing bolt 6 of the top block 4.
  • the Figures 18 and 19 show the reversing means 8 in its disengaged position.
  • the top block 4 with its reversing bolt 6 can at least temporarily bear weight on the reversing arm 13 of the reversing means 8 , it is advantageous for the reversing arm 13 to be shorter than the stop arm 14 of the reversing means 8 .
  • the stop 28 is arranged between a coupling point 29 of the supporting structure 9 of the crane 1, for example adjacent to a pulpit of the crane 1, and a working point 30 of the trolley 11 closest to the coupling point 29 on the supporting structure 9 of the crane 1.
  • figure 1 makes it clear that the reversing means 8 has already contacted the reversing stop 12 before the trolley 11 has reached its stop 28 . In this way it is possible to move the reversing means 8 from the initial position to its uncoupling position by moving the trolley 11 against its stop 28 .
  • the control unit 27 comprises a computer-readable medium 31, namely a data memory, on which a computer program 32 is stored, which comprises instructions which cause the crane 1 to carry out the method steps of the methods for reversing the crane 1 explained above.
