unter Benutzung von Räderwerlien erfolgt, die den gebräuchlichen Hebewerken gleichen und durch Menschenhand betrieben werden. Die Manövrierfähigkeit und Betriebssicherheit solcher Leitern hangt alsdann in erster Linie von dem mehr oder weniger vollkommenen Ausbau dos benutzten Triebwerkes, daneben aber auch von der Zuverlässigkeit der Be-
EMI1.3
Bei der vorliegenden Erfindung wird dieser Vorteil dadurch erreicht, dass das zum Ausziehen des Leiterausschubes dienende Räderwerk nicht mehr wie seither, unmittelbar durch die Bedienungsmannschaft selbst. sondern vielmehr durch einen besonderen Motor betätigt wird, der durch Druckluft, gepresste Kohlensäure oder ein ähnliches Mittel betrieben werden kann.
EMI1.4
Zutritt des Betriebsmittels in den Motor erfolgt aus dem Behälter d durch das Rohr c und wird durch einen Hahn e gesteuert, der zunächst von Hand aus gestellt werden kann, ausserdem aber selbsttätig von dem Leiteranszug so beeinflusst wird, dass ein zti weitgehendes

stück ausgebildet ist.
Auf dieses Querstuck trifft heim Ausschieben der Leiter kurz vor Erreichung des grössten zulässigen Ausschubes ein am verschiebbaren Leiterteil k vor- gesehener Anschlag 1auf, wodurch die Stange g mitgenommen und der Hahn c geschlossen wird, so dass der Motor n zum Stillstand gelangt.

takes place using wheels that are similar to the usual lifting gear and are operated by human hands. The maneuverability and operational safety of such ladders then depends primarily on the more or less complete expansion of the engine used, but also on the reliability of the
EMI1.3
In the present invention, this advantage is achieved by the fact that the gear train used to pull out the ladder extension is no longer operated directly by the operating team as it has been since then, but rather by a special motor operated by compressed air, compressed carbon dioxide or a similar means can.
EMI1.4
The operating fluid enters the engine from the container d through the pipe c and is controlled by a tap e, which can initially be set by hand, but is also automatically influenced by the conductor pull so that a zti extensive

piece is formed.
When the ladder is pushed out, a stop 1 provided on the slidable ladder part k hits this cross piece shortly before reaching the maximum admissible extension, whereby the rod g is carried along and the cock c is closed so that the motor n comes to a standstill.
