Abstract

Die vorliegende Erfindung betrifft einen Teleskopausleger für Hubarbeitsbühnen, insbesondere für fahrbare und selbstfahrbare Hubarbeitsbühnen, mit mehreren zueinander verschiebbar angeordneten Telekopträgern, wobei der äußere Teleskopträger (12) zur Aufnahme und Führung der inneren Teleskopträger (14, 16, 18) dient und mindestens drei der inneren Teleskopträger (14, 16, 18) miteinander gekoppelt und verschiebbar sind und eine Teleskopträgergruppe bilden, wobei wenigstens die innersten zwei Teleskopträger (16, 18) über mindestens zwei Ketten- oder Seilzüge (20, 26) miteinander verbunden sind. Erfindungsgemäß steht der äußere Teleskopträger (12) und mindestens die beiden äußeren Teleskopträger (14, 16) der Teleskopträgergruppe (14, 16, 18) über einen einzelnen, innerhalb des Teleskopauslegers (10) angeordneten, doppelwirkenden und mindestens doppelstufigen Teleskopzylinder (36) in Wirkverbindung zueinander.

The present invention relates to a telescopic boom for aerial work platforms, in particular for mobile and self-propelled aerial work platforms, with a plurality of telescopic supports arranged to be displaceable relative to one another, the outer telescopic support (12) being used for receiving and guiding the inner telescopic supports (14, 16, 18) and at least three of the inner ones Telescopic supports (14, 16, 18) are coupled to one another and displaceable and form a telescopic support group, at least the innermost two telescopic supports (16, 18) being connected to one another via at least two chain or cable hoists (20, 26). According to the invention, the outer telescopic support (12) and at least the two outer telescopic supports (14, 16) of the telescopic support group (14, 16, 18) are operatively connected via a single, double-acting and at least double-stage telescopic cylinder (36) arranged within the telescopic boom (10) to each other.
