Input (Czech): Sestava (12) zahrnuje podlouhl² prvn  nosn k (20) a podlouhl² druh² nosn k (22), z nich  ka d² m  protilehl² horn  a doln  konec. Horn  konec prvn ho nosn ku (20) je opat°en otvorem, do kter ho je teleskopicky zasunut spodn  konec druh ho nosn ku (22) a k horn mu konci prvn ho nosn ku (20) je oto n  p°ipojena sk°   (40) pr choz ho kloubov ho mechanismu (38). Sk°    (40) je opat°ena pr choz m otvorem pro suvn  ulo en  druh ho nosn ku (22). Mezi prvn m nosn kem (20) a druh²m nosn kem (22) jsou uspo° d ny pohonn  prost°edky pro vz jemn  teleskopick  p°estavov n  prvn ho nosn ku (20) v  i druh mu nosn ku (22). Ke sk° ni (40) jsou p°ipojeny prost°edky pro nat  en  sk° n  (40) vzhledem k prvn mu nosn ku (20). Sk°   (40) je oto n  p°ipojena k horn mu konci prvn ho nosn ku (20) pomoc  p ru s odstupem od sebe uspo° dan²ch souos²ch  ep  (82, 84), kter  definuj  pevnou osu (42) ot  en . Mezi  epy (82, 84) je mezera pro pr chod druh ho nosn ku (22), jeho  spodn  konec je oto n  spojen s pohonn²mi prost°edky. Druh² nosn k (22) je na spodn m kopci opat°en p rem vodic ch dr  ek (90), pro p°ijet   ep  (82, 84) a pro vyrovn n  osy oto n ho spojen  s pevnou osou  (42) ot  en , kdy  se druh² nosn k (22) teleskopicky vysune do pln  vysunut  polohy vzhledem k prvn mu nosn ku (20).\
Output (English): The assembly (12) includes an elongated first carrier (20) and an elongated second carrier (22), each of which opposes the upper and lower ends. The upper end of the first carrier (20) is provided with an opening into which the lower end of the carrier (22) is telescopically inserted and the upper end of the first carrier (20) is swiveled (40) ) the articulation mechanism (38). Sk ° (40) is provided with a slide hole for the type of support (22). Between the first carrier (20) and the second carrier (22) there are means for the telescopic adjustment of the first carrier (20) in the second carrier (22). Devices (40) are connected to the housing (40) relative to the first carrier (20). Sk ° (40) is connected to the upper end of the first carrier (20) by means of spaced apart coaxial axes (82, 84) which define a fixed axis (42) open. Between the eps (82, 84) there is a gap for the passage of the type of carrier (22), its lower end being connected to the propulsion means. The second carrier (22) is provided on the lower hill with guide rails (90), for ep (82, 84) and for alignment of the axis it is connected to the fixed axis (42) ot when the second carrier (22) is telescopically extended to the fully extended position relative to the first carrier (20). \ t
