Accordingly, a further extension of articulated masts with at least five boom arms is possible if the control device for Mastarm Gay has a responsive to the selected Abstützkonfiguration subroutine or limiting circuit, which also limits the pivoting angle of the third Mastarms about its bending axis.
  • the alternatively provided limiting circuit expediently has at least one limit switch.
  • the invention is seen above all in that the control device for the Mastarmamba a blocking device has, which blocks the buckling drive of the first mast arm in its aligned substantially parallel to the vertical axis position.
