The present invention relates to a telescopic sliding beam for supporting a work machine comprising a sliding beam box and an internal sliding beam that is outwardly telescopically supported in the sliding beam box. The sliding beam box and the internal sliding beam have an opening in the peripheral region, with the openings overlapping one another in an outwardly telescoped state, and with a bolt being able to be introduced into the overlapping openings. The sliding beam box has an abutment at its inner side and the internal sliding beam has an abutment at its outer side, with the abutment of the sliding beam box and the abutment of the internal sliding beam contacting one another in an outwardly telescoped state such that a further pulling of the internal sliding beam out of the sliding beam box is suppressed. The invention furthermore comprises a work machine comprising this telescopic sliding beam.

1. A telescopic sliding beam for supporting a work machine, comprising: a sliding beam box; andan internal sliding beam that is outwardly telescopically supported in the sliding beam box, whereinthe sliding beam box and the internal sliding beam each have an opening in a peripheral region, with the openings overlapping one another in an outwardly telescoped state of the telescopic sliding beam, and with a bolt introduceable into the overlapping openings;the sliding beam box has an abutment at only one inner side at the peripheral region; andthe internal sliding beam has an abutment at an outer side, wherein the abutment is an outwardly projecting collar, with the abutment of the sliding beam box and the abutment of the internal sliding beam contacting one another in the outwardly telescoped state such that a further pulling of the internal sliding beam out of the sliding beam box is suppressed;wherein the opening of the sliding beam box and the opening of the internal sliding beam overlap one another when the abutment of the sliding beam box and the abutment of the internal sliding beam contact one another. 2. The telescopic sliding beam in accordance with claim 1, wherein the opening of the sliding beam box and the opening of the internal sliding beam are arranged in a respective top chord; and the abutment of the sliding beam box and the abutment of the internal sliding beam are arranged in a respective bottom chord. 3. The telescopic sliding beam in accordance with claim 1, wherein the abutment of the sliding beam box is formed in one piece with the sliding beam box and/or the abutment of the internal sliding beam is formed in one piece with the internal sliding beam. 4. The telescopic sliding beam in accordance with claim 1, wherein the opening of the sliding beam box and the opening of the internal sliding beam are of identical form. 5. The telescopic sliding beam in accordance with claim 1, wherein the opening of the sliding beam box and the opening of the internal sliding beam are arranged directly above one another in the outwardly telescoped state. 6. The telescopic sliding beam in accordance with claim 1, wherein, in a marginal region of its opening, the sliding beam box has an outwardly or inwardly projecting elevated portion that is perpendicular to a telescoping direction of the sliding beam and that is aligned with the opening in the peripheral region of the sliding beam box. 7. The telescopic sliding beam in accordance with claim 6, wherein the perpendicular elevated portion is formed in one piece with the sliding beam box. 8. The telescopic sliding beam in accordance with claim 1, wherein, in the outwardly telescoped state of the sliding beam, a gap is present between the inner side of the sliding beam box and the outer side of the internal sliding beam, with the gap being larger than or equal to a height of the abutment at the outer side of the internal sliding beam. 9. The telescopic sliding beam in accordance with claim 1, wherein, in an outwardly telescoped state of the siding beam, an insertion block is inserted into a gap between the inner side of the sliding beam box and the outer side of the internal sliding beam. 10. The telescopic sliding beam according to claim 4, wherein the opening of the sliding beam box and the opening of the internal sliding beam have a circular or rectangular shape. 11. The telescopic sliding beam according to claim 5, wherein the opening of the sliding beam box and the opening of the internal sliding beam are aligned flush with one another. 12. The telescopic sliding beam according to claim 7, wherein the perpendicular elevated portion surrounds the entire marginal region of the opening of the sliding beam box. 13. The telescopic sliding beam according to claim 8, wherein the gap is between a top chord of the sliding beam box and a top chord of the internal sliding beam. 14. The telescopic sliding beam in accordance with claim 9, wherein the gap is between a top chord of the sliding beam box and a top chord of the internal sliding beam. 15. A work machine having a telescopic sliding beam for supporting the work machine, comprising: a sliding beam box; andan internal sliding beam that is outwardly telescopically supported in the sliding beam box,wherein the sliding beam box and the internal sliding beam each have an opening in a peripheral region, with the openings overlapping one another in an outwardly telescoped state of the telescopic sliding beam, and with a bolt introduceable into the mutually overlapping openings;the sliding beam box has an abutment at only one inner side at the peripheral region;the internal sliding beam has an abutment at an outer side, wherein the abutment is an outwardly projecting collar, with the abutment of the sliding beam box and the abutment of the internal sliding beam contacting one another in an outwardly telescoped state such that a further pulling of the internal sliding beam out of the sliding beam box is suppressed;wherein the opening of the sliding beam box and the opening of the internal sliding beam overlap one another when the abutment of the sliding beam box and the abutment of the internal sliding beam contact one another. 16. The work machine according to claim 15, wherein the work machine is a mobile crane or an excavator.
