A drive of a sliding connecting member of a locking system of a telescopic system, having a telescopic cylinder (1) with an outer telescopic section (2, 3) and an inner telescopic section (6, 7), which are each provided with a locking hole (5) into which a locking bolt (11) can be entered and withdr
A drive of a sliding connecting member of a locking system of a telescopic system, having a telescopic cylinder (1) with an outer telescopic section (2, 3) and an inner telescopic section (6, 7), which are each provided with a locking hole (5) into which a locking bolt (11) can be entered and withdrawn in a releasable manner via the sliding connecting member (14), provided with a sliding path (12), and a grasper (10), wherein the locking bolt (11) is designed to be moveable by means of an engagement member (9) running in the sliding path (12) in such a way that the locking bolt (11) effects a linear movement and the jib sections (3, 6) can be connected to one another by insertion of the locking bolt (11) into the bolting hole (5) and the sliding connecting member (14) can be driven by an electric linear drive (4).

1. Crane jib with a locking system of a telescopic system, comprising: an outer telescopic section having a lower shell (2) and an upper shell (3);an inner telescopic section longitudinally displaced within the outer telescopic section, the inner telescopic section having an upper shell (6) and a lower shell (7); anda telescopic cylinder (1) at least partially received within the inner telescopic section, and the upper shell (3) of the outer telescopic section and the upper shell (6) of the inner telescopic section are each provided with a bolting hole (5) into which a locking bolt (11) is entered and withdrawn in a releasable manner via an electric linear drive (4) driving a sliding connecting member (14), provided with a sliding path (12) in which an engagement member (9) is guided, the engagement member (9) is in operating connection with the locking bolt (11), via a grasper (10), wherein the locking bolt (11) is moveable by the grapser (10) in connection with the engagement member (9) running in the sliding path (12) in such a way that the locking bolt (11) effects a linear movement and the upper shell (3) of the outer telescopic section is connected to upper shell (6) of the inner telescopic section by insertion of the locking bolt (11) into the bolting hole (5). 2. The device of claim 1, wherein the electric linear drive (4) is connected to a control unit (20) via a cable (23) and can thereby be controlled. 3. The device of claim 2, wherein the electric linear drive (4) is provided with integrated sensing system (4a) for location detection or with a separate position detection means (8a) for a connection of the sliding connecting member (14) to the linear drive. 4. The device of claim 3, wherein the electric linear drive (4) is provided with a mechanical self-locking means. 5. The device of claim 4, wherein the electric linear drive (4) is provided with a holding brake. 6. The device of claim 5, wherein the holding brake is formed as a self-locking means and holds a respectively approached position without application of electric power. 7. The device of claim 1, wherein the bolting arrangement of the telescopic sections (3, 6, 2, 7) is provided with two bolting holes (5). 8. The device of claim 7, wherein for the bolting of two telescopic sections (3, 6, 2, 7) to one another, two bolting holes are provided in each case, wherein the lateral bolting holes (5) are disposed opposite one another and are bolted to one another by a respective dedicated locking bolt (11).
