STRUCTURE AND FUNCTION
12/51 FORCE-LIFT
®
Functional Description
The vacuum lifter consists of the following main components:
(1) Swivel joints with eyelet (2) Lift tube
(3) Control head (4) Suction foot
(5) Supply line (6) Filter unit
(7) Motor protection (8) Vacuum pump/blower
(9) Pillar-mounted slewing crane + jib
Functional description
The vacuum generator (8), pump or blower depending on the use, generates the air flow volume
and provides the vacuum. The vacuum or the generated air flow reaches the product to be
transported through the filter unit (6), via the supply line (5), the lift tube (2), the control head (3)
and then the suction foot (4).
If the suction foot is placed on the product to be transported, e.g. a cardboard box, the device
attaches itself. The external air, which previously streamed in through the suction foot, is
decreased or stops completely which in turn increases the vacuum in the entire system. With the
rapidly increasing vacuum, the previously untensioned lift tube starts to tighten. A spring is
integrated in the lift tube to ensure, among other things, that the lift tube does not implode due to
the vacuum. As soon as the lifting force (negative pressure x lift tube cross-section area) is greater
than the weight of the product to be transported, the product can be lifted.
Regulating the external air in the control head either raises or decreases the vacuum in the entire
system. Adding external air reduces the
