- the rotary member 68 is rotatably driven in accordance with FIG. 1 1 clockwise about the axis of rotation 67.
- the roller chain 70 is driven clockwise around the gears 71 and by means of the coupling element 40 b
- Counterweight unit 24 shown in FIG. 1 1 shifted from left to right to the Kragelement 23 out.
- the counterweight unit 24 is decoupled from the first force transmission element 70 and coupled on the cantilever element 23 by means of the locking unit 64.
- the rotary member 68 is displaced downwardly along the coupling direction 69 until the rotary member 68 is engaged with the second power transmission member 72 (FIG. 12).
- Rotary shaft 67 rotatably driven in the counterclockwise direction.
- the second power transmission element 72 by means of a first
- Power transmission element / coupling element 76 is coupled to the first telescopic element 31.
- the first telescopic element 31 is telescoped out.
- Telescopic element 32 is shown in FIGS. 15 and 16.
- FIG. 16 A doubly extended maximum telescoping condition of the counterweight adjustment device 19b is shown in FIG. A Einteleskopieren done in accordance with the reverse procedure.
- Clamping unit 14 is tensioned on the uppercarriage.
- a bracing 46 is provided from the top of the superlift mast 79 to the cantilever element 23.
- the bracing 46 may preferably be coupled in the center of gravity of the counterweight unit 24. A coupling outside of the center of gravity is possible.
- a coupling between the superstructure 8 and the longitudinal member 22 may be advantageous.
- the A-frame 15 is connected via the cable sheath 16 with the top of the superlift mast 79.
- the triangle formed by the A-frame 15, the reeving 16 and the superlift mast 79 is rigid.
- the triangle is rotatable about the axis of rotation 80 on
- Counterweight unit 24 on the superlift mast 79 is designed in particular by support rods, which have a constant length. In a shift of
- Counterweight unit 24 by means of the cantilever 23, the counterweight unit 24 is non-linearly displaced, in particular along an arc segment. To ensure support on the ground, the vertical supports 28 can
- the support rods of the bracing 46 may be made variable in length to allow a displacement of the counterweight unit 24 along a linear direction.
