FIELD: transport.SUBSTANCE: invention relates to latching device for locking drop arm on input shaft of semitrailer extension supporting pillar. System for semitrailer extension supporting pillar control includes arm (20) and latching device (30) for locking drop arm (20) on input shaft (10) of extension supporting pillar. The arm (20) is fixed on input shaft (10) by articulated joint and with possibility to be turned from inoperative removed position (I) into thrown-out operative position (II). The latching device (30) contains mounting section (31) for mounting on arm (20), as well as cramp (33) connected with mounting section (31) for spring attachment on which one locking section (34) is made. The locking section (34) in thrown-out operative position (II) of arm (20) encloses input shaft butt end (10) partially with form closure and at the same time is made with pretension or stretched (F) relative to this input shaft butt end (10) thus providing detachable locking of the arm (20).EFFECT: easier operation of thrown-out or rotary arms of extendible supporting pillars.10 cl, 6 dwg |
