Title (EN) BARRIER WITH RETRACTABLE POST
(FR) BARRIERE AVEC POTEAU ESCAMOTABLE
Abstract: front page image
(EN)The retractable post (9) is guided on two locations by two sets of rollers (10) arranged in a cross and facing each other. The supports of the different rollers (10) are mounted inside a support structure (6) carrying on the upper face thereof a cover plate (3) which is traversed by the sliding post (9). The barrier may be mounted as a unit in a well (1), the cover plate (3) being used both as a unique support of the barrier and as a closure, an electric motor (13) with autoblocking transmission lifts or lowers the post (9) by means of a chain, belt or rack drive (15). The autoblocking transmission stops the post (9) in its extreme positions; a clutch (18) which may be actuated from the outside allows the manual displacement of the post.

La barriere peut etre montee comme unite dans un puits (1) la plaque de couverture (3) servant a la fois de support unique a la barriere et de fermeture, un moteur electrique (13) a transmission autobloquante fait monter ou descendre le poteau (9) grace a un entrainement a chaine, courroie ou cremaillere (15).
