<p>The system comprises multiple guides fixed or implemented in a border zone of a platform. The vertical movement of multiple panels noticeably passes through the platform, which is formed in a barrier. The barrier protects against the fall of people in the channel zone, which is absent from a convoy. An articulated skate is prepared in each convoy, with extreme flanks of entry and exit, acting on some mounted pulley wheels in each panel to produce the automatic retractions in the passage while controlling the action of some average media recovery.</p> |
