2.5.1 Compressed air deactivation when using an ejector:
2.6 Rotary union
2.7 Supply hose/compressed air hose
The supply hose transfers the vacuum generated by the vacuum pump to the rotary union of the tube
lifter.
The necessary compressed air is supplied to the ejector via the compressed air hose.
The length of the supply hose is adapted to the application, but must not exceed
50 m as otherwise the correct function of the vacuum tube lifter JUMBO would no
longer be guaranteed.
The diagram opposite shows compressed air being turned off on
SEM 100/SEM 150 (here with ball valve closed).
Compressed air is turned off by means of the activation cable
attached to the side of the ejector. The activation cable is approx.
0.9 m in length. The two balls located on the activation cable
(black and red) are used to open and close the valve.
To open the valve, pull on the black ball. To close it again, pull on
the red ball.
Compressed air should be switched off at the pressure-reduction
valve (item 8) at end of the shift.
The rotary union connects the vacuum supply hose (from the vacuum
generator ) with the lift tube of the vacuum tube lifter. At the same
time, the vacuum tube lifter
J
UMBO
is connected to the crane system
by the suspension eye on the rotary union.
The connection between the lift tube and rotary union is infinitely
rotatable to enable the tube lifter to be continuously rotated.
The rotary union contains the tube lifter safety valve, which causes the
tube lifter to be lowered slowly in the event of a vacuum supply failure.
The vacuum tube lifter
J
UMBO
must only be attached to the rotary
union via the eyelet!
