# Vacuum lifting arrangement and lifting tube for use therein

## Abstract

A vacuum lifting arrangement having a lifting tube and a suction foot for engaging with an object to be lifted, is disclosed, said vacuum lifting arrangement having a pneumatic valve fluidly connected to ambient air, wherein, during operation of the vacuum lifting arrangement, when an object is not engaged with the suction foot, an air-flow from the suction foot into the lifting tube is prevented by the valve which is in a closed position, and, upon generation in the suction foot of a pressure lower than the surrounding pressure, e.g. due to engagement with an object to be lifted, the valve will be in an open position, allowing an-air flow from the suction foot into the lifting tube. A lifting tube comprising a pneumatic valve for use in the lifting arrangement is also disclosed.
