# Vacuum lifting tube arrangement having extension-lockable lifting tube

## Abstract

A vacuum lifting tube arrangement is disclosed comprising a lifting tool attached to a flexible lifting tube which is retractable from an extended state and extendible from a contracted state, respectively, and a controllable source of vacuum fluidly connected to an inner volume of the flexible lifting tube, and more particularly additionally comprising a locking mechanism preventing extension of the flexible vacuum lifting tube from a contracted state upon deactivation of the source of vacuum.
