- 10a-h different Verbolzungspositionen can be provided per telescopic section, which then set a telescopic section 10a-h in a full or half or otherwise pre-selected extension path of the telescopic section 10a-h.
- the cables 16a, 16b are then tensioned successively and in sections in the same manner between the respective guy supports 15 of the telescopic sections 10a-g and the boom base box 9. It is important here that the unclamping of the ropes 16a, 16b not only between the attachment points 20a and 20b and the

- the holding mechanism 17 is in each case
- first counter-holding element 24a or second counter-holding element 24b each with a first holding element 27a
- a pulley in particular in the form of a pulley, or a second holding element 27b, in particular in the form of a pulley, cooperate to hold or clamp the respective cable 16a, 16b between them.
- Counter holding element 24a, 24b is formed in each case as a stationary contact surface of the respective leg 15a and 15b and is located in each case at one of
- Telescopic boom 8 opposite end of the legs 15a and 15b and adjacent to the through holes 22a and 22b.
- the abutment surface is adapted to the contour of the rope 16a, 16b and can have an increased frictional resistance.
- each of the legs 15a and 15b receives a rod-shaped sliding element 25a, 25b.
- the sliding element 25a, 25b is thus respectively integrated in the legs 15a and 15b and receives at its end facing away from the telescopic boom 8 in each case one of the holding elements 27a, 27b.
- the sliding element 25a, 25b along the legs 15a and 15b of the guy support 15 is displaceable.

- the width b is about 200 cm and the length I of the legs 15a, 15b about 95 cm.
- these dimensions can be interpreted differently.
- the right compromise must be found to achieve a load increase without exceeding the legal vehicle width and height for road operation ,
- the holding mechanism 17 is described in a mechanical construction. In principle, it is also conceivable to drive the holding mechanisms 17 electrically, hydraulically or pneumatically. Also, instead of the holding elements 27a, 27b and the rollers 26a, 26b sliding elements may be provided.
- FIGS. 5 to 9 show, in addition to that described in FIG.
- the invention is not limited to these five exemplary ones
- the cable 16a, 16b can be held on the guy support 15 by frictional engagement and / or by positive locking via the retaining mechanism 17 applied by the holding mechanism 17.
- Figures 5 and 6 show exemplary embodiments of a
- Holding mechanism 17 which holds by means of traction the rope 16a, 16b.
- a first holding element 27a or a second holding element 27b is moved in a linear actuating direction R from an open position to a holding position.
- the holding element 27a, 27b acts on the cable 16a, 16b with a holding force H and pushes it against the first counter-holding element 24a and / or the second counter-holding element 24b.
- the holding force H thus acts at a right angle to a longitudinal direction of the cable 16a, 16b and in the direction of the opposing counter-holding element 24a, 24b.
- the holding element 27a, 27b is designed as a clamping wedge, which is displaceable along a ramp 28 in the direction of actuation R.
- the ramp 28 in this case runs parallel to the longitudinal direction of the rope 16a, 16b and increases in the longitudinal direction of the rope 16a, 16b seen.
- the retaining element 27a, 27b is moved toward the cable 16a, 16b in the direction of the holding force H via the ramp 28 and thus presses the cable 16a, 16b against the counter-holding element 24a, 24b frictionally clamped.
- the wedge-shaped holding member 27a, 27b has a clamping force enhancing effect. If the cable 16a, 16b further pulled in the pulling direction Z, this takes over the wedge-shaped retaining element 27a, 27b with frictional engagement. This thereby moves the ramp 28 further high and increases the holding force H in the direction of the cable 16a, 16b.
- Holding element 27a, 27b provided on its the rope 16a, 16b facing surface with a profiling that is substantially complementary to the outer surface of the rope 16a, 16b formed and thus positively engages the surface of the rope 16a, 16b.
- the strands 29 of the rope 16a, 16b form a surface of the rope 16a, 16b with a helical and thread-like structure.
- the holding mechanism 17 uses a positive connection.
- the holding element 27a, 27b is thereby displaced in the direction of actuation R, as in FIGS. 5 and 7.
- the cable 16a, 16b is provided at least in the region of the holding mechanism 17 with longitudinally spaced-apart moldings 30 pressed onto one another.
- the holding element 27a, 27b is provided on its surface facing the cable 16a, 16b with a profiling which is complementary to the outer surface of the cable 16a, 16b with its shaped pieces 30 , At least one
- Shaped piece 30 is held by the holding element 27a, 27b in the holding position
- retaining element 27a, 27b and the counter-holding element 24a, 24b may be equipped with a profiling (not shown), which is for receiving the
- Fittings 30 is suitable and thus the rope 16a, 16b additionally prevents it from being pulled in the pulling direction Z.
- the holding mechanism 17 shown in FIG. 9 is also essentially a form-fit, which is used to hold the rope 16a, 16b.
- FIG. 9 shows a retaining element 27a, 27b which, in the manner of a nut, rests on the rope 16a, 16b with its profiled, thread-like outer
- These holding elements 27a, 27b can rotate correspondingly to the thread produced by the wire strands 30 when the cable 16a, 16b is moved in or against the pulling direction Z - for example when extending and retracting the telescopic boom 8.
- the rotational movement of the holding member 27 a, 27 b to block is between the
- Counter holding element 24a, 24b in which the holding element 27a, 27b is rotatably mounted, and the holding element 27a, 27b, a blocking device, for example a Brake, provide. This is indicated in the figure 9 by the arrow B.
- the holding member 27a, 27b When the holding member 27a, 27b is prevented from rotating, the holding member 27a, 27b, like the embodiment of FIG. 7, holds the cord 16a, 16b against the pulling direction Z.
- guy system 1 1 also works with chains instead of ropes 16a, 16b, so that in the context of the invention, the ropes 16a, 16b are to be understood as a flexible traction means.
