Description

Bei Elektro-Staplern, welche von einer Etage in die andere fördern, ist es möglich, daß das Fördergut über die Plattform hinausragt und Quetschgefahr besteht. Hiergegen ist eine Sicherheitsschaltung vorgesehen, in der Weise, daß ein Bügel B in der Länge der Durchbruchsöffnung hart an dieselbe anschließt, mit Bewegungsmöglichkeit nach oben. Falls nun das Fördergut F über die Plattform P hinausragt, wird dasselbe den Bügel heben und hierdurch einen elektrischen Ausschalter S betätigen, welcher den Stromkreis des Antriebsmotors unterbricht und dadurch das Hubwerk sofort zum Stillstand bringt. Nun kann die Plattform nur gesenkt werden, um das Überragen des Fördergutes zu beseitigen. Es ist also diese Sicherheitsschaltung in ihrer Wirkungsweise gleich einem Endschalter und es fehlte bisher bei Elektro-Staplern, welche für Etagenförderung benutzt werden, eine solche Sicherheitsvorrichtung. Die bekannte Sicherheit durch aufklappbare Bohlen würde sich in der Herstellung des Durchbruches zu kostspielig stellen und auch zuviel Platz beanspruchen.For electric forklifts that move from one floor to the other, it is possible that the material to be conveyed protrudes beyond the platform and there is a risk of crushing consists. Against this, a safety circuit is provided in such a way that a Bracket B adjoins the same hard in the length of the breakthrough opening, with the possibility of movement up. If the conveyed material F protrudes beyond the platform P, the same will happen lift the bracket and thereby actuate an electrical off switch S, which interrupts the electric circuit of the drive motor and thereby the hoist immediately to the Brings to a standstill. Now the platform can only be lowered to prevent the To remove the conveyed material. So it is this safety circuit in its mode of operation equal to a limit switch and so far electric forklifts have not had one for floor conveying be used such a safety device. The well-known security through hinged planks would be too costly to produce the breakthrough and take up too much space.

Die beschriebene vorliegende Erfindung ist eine absolut sicher wirkende Vorrichtung.The present invention described is an absolutely safe one Contraption.
