Abstract
Description
Diese Erfindung bezieht sich auf eine Überkopf-Arbeitsbühne, bestimmt, um an dem Ende eines Hebearms eines Hebefahrzeugs angebracht zu sein, z.B. von dem Typ, wie er im Dokument EP-A-0375705 von der Anmelderin beschrieben ist.These The invention relates to an overhead working platform intended to to be attached to the end of a lift arm of a lift truck be, e.g. of the type described in EP-A-0375705 of the Applicant is described.
Ein Problem solcher Arbeitsbühnen ist, dass die Abmessung ihrer maximalen lichten Höhe in senkrechter Richtung bezüglich der Fortbewegungsrichtung des Fahrzeugs innerhalb eines Werts liegen muss, welcher durch die Regeln der Straßenverkehrsordnung in den Regelungen zum maximalen Lichtraumprofil von Fahrzeugen, welche sich auf Straßen bewegen, definiert ist. Oft ist die vom Gesetz bestimmte maximale Höhe für die Zwecke der Benutzer solcher Arbeitsbühnen zu gering.One Problem of such work platforms is that the dimension of their maximum clear height in vertical Direction regarding the direction of travel of the vehicle must be within one value, which by the rules of the Highway Code in the regulations to the maximum clearance profile of vehicles moving on roads, is defined. Often the maximum height determined by law is for the purpose the user of such work platforms too low.
Ausziehbare Überkopf-Arbeitsbühnen wurden vorgeschlagen, wie etwa Arbeitsbühnen, welche in der Lage sind, eine Transportkonfiguration anzunehmen, deren Höhe innerhalb der Grenzen des Gesetzes liegt, und eine Konfiguration zum Arbeiten, bei welcher die Höhe größer ist.Extendible overhead work platforms were proposed, such as work platforms, which are able to adopt a transport configuration, their height within the limits of the law, and a configuration to work, at which the height is larger.
FR-A-2466586 offenbart eine ausziehbare Überkopf-Arbeitsbühne, welche einen zentralen Abschnitt mit einer rechtwinkligen Bodenwand einschließt, ausgerüstet mit Anbringungsvorrichtungen zum Verbinden der Arbeitsbühne mit dem Ende eines Hebeauslegers, und ein Paar von Seitenabschnitten, welche sich bezüglich dem Zentralabschnitt bewegen können, so dass die Arbeitsbühne eine geschlossene Anordnung zum Transport und eine offene Anordnung zum Arbeiten annehmen kann. Jeder der Seitenabschnitte ist an dem Zentralabschnitt angelenkt und bewegbar von einer abgehobenen Position, entsprechend der geschlossenen Anordnung, und einer abgesenkten Position, entsprechend der offenen Anordnung.FR-A-2466586 discloses an extendible overhead work platform which a central portion with a rectangular bottom wall, equipped with Attachment devices for connecting the work platform with the end of a lift boom, and a pair of side sections which with respect can move the central section, so the work platform a closed arrangement for transport and an open arrangement to accept work. Each of the side sections is on the Center section articulated and movable from a raised position, according to the closed arrangement, and a lowered position, according to the open arrangement.
Eines der Hauptprobleme der bekannten Arten von ausziehbaren Überkopf-Arbeitsbühnen ist, dass die Öffnungs- und Schließungsvorgänge nur durch ein Betätigen von außerhalb der Arbeitsbühnen her erfolgen können. Folglich können solche Vorgänge nicht durchgeführt werden, wenn die Arbeitsbühne vom Boden angehoben ist.One The major problem of the known types of telescopic overhead work platforms is that the opening and closing operations only by an actuation from outside of the work platforms can take place. Consequently, you can such events not done be when the work platform lifted from the ground.
Es ist die Aufgabe dieser Erfindung, eine ausziehbare Überkopf-Arbeitsbühne vorzusehen mit einer einfachen Struktur, welche durch Betätigen von der Innenseite der Arbeitsbühne her geöffnet und geschlossen werden kann.It The object of this invention is to provide an extendable overhead platform with a simple structure, which by pressing from the inside of the platform opened and can be closed.
Gemäß dieser Erfindung wird eine solche Aufgabe erreicht durch eine Überkopf-Arbeitsbühne mit den Merkmalen des Anspruchs 1. Die Merkmale und Vorteile dieser Erfindung werden in einer bevorzugten Ausführungsform dargestellt werden, welche als nicht beschränkendes Beispiel mit Bezug auf die eingefügten Zeichnungen gegeben wird, wobei:According to this Invention, such an object is achieved by an overhead work platform with the features of claim 1. The features and advantages of this Invention will be illustrated in a preferred embodiment, which as non-limiting Example given with reference to the attached drawings, in which:
