3.2 Rotary Suction
Fitting
The rotary suction fitting is connected to the suction hose of the blower and the
lifting tube (3).
The lifting device is suspended on the rotary suction fitting.
The lifting device can be rotated endlessly.
3.3 Lifting Tube
The lifting tube transmits the vacuum to the vacuum head(s) and realize the lifting
movement of the lifting device.
3.4 Control Unit
With the control unit the lifting and lowering of loads is controlled by changing the
vacuum in the lifting device. It regulates the flow of outside air to the lifting unit.
The flow of outside air and therefore the vacuum is controlled by an orifice disc.
It is operated by a regulator lever (Pos. 4.2). The load is lifted when the control
opening is fully closed by the slider. The farther the control opening is open, the
more outside air will be drawn in. The load will lower.
