Lifting loads with a vacuum hose lifter:
How does a hose lifter work?
Vacuum hose lifters are devices that facilitate the lifting and moving of objects, especially large loads.
When used, a vacuum pump draws air out of the lifting unit through a vacuum hose, creating a vacuum. In the process, the object to be lifted and the suction cups are pressed against each other, sucked in, so to speak. The difference in pressure between the vacuum and the surrounding air creates the lifting force. When the operating lever is actuated, the vacuum in the lifting hose increases, it contracts further and the load is lifted. When the load is to be lowered again, the operating lever opens the valve again, the hose expands, and the load is lowered. The focus here is on work safety: as the loads are lifted by the vacuum, they remain sucked in even in the event of a possible power failure, leakage causes the vacuum in the lifting hose to reduce slowly and the load is lowered safely.
