3.5.2 Handling of glass and façade elements standing upright
⇒
Move the crane with the attached OKTOPUS
®
GLASS-Jack GL-N 400/300 to the ele-
ments. Position the suction pads parallel to the suction area by driving and lifting move-
ments of the crane as well as manual guidance.
In order to avoid unintended rotating or tilting of the load, you have to en-
sure that the release levers are engaged (see fig. 8)!
⇒
Position the suction pads of the OKTOPUS
®
above center of mass of the load (
±
5 cm)
and place it on the suction area. If the surface of the construction element is coated with
protective film, it has to be removed at least in the area of the suction pads before plac-
ing the OKTOPUS
®
.
⇒
Now the construction element is suctioned. Slightly lift the switch “Suction/Release” (see
fig. 6) and slide it towards “Suction“ until it latches (see also section 3.4 “Startup“).
⇒
You can lift the load only if the red warning light and the alarm buzzer have turned off,
the vacuum gauges indicate that the working range has been reached (see figure 5) and
you have ensured that nobody is in the danger area.
⇒
Do not lift the load higher than necessary!
⇒
Fix the element at the installation site in that way, that it does not pose a threat after be-
ing released from the OKTOPUS
®
!
⇒
Then the construction element is released by slightly lifting the switch “Suction/Release“
and sliding it towards “Release“. Lifting the switch is an additional measure against unin-
tentional operating errors.
If your OKTOPUS
®
is equipped with the optional blow-off function, subsequently press
the button “Blow-off” (see fig. 1, pos. 15). Keep the button pressed until all suction pads
have completely disengaged from the load. In this case the suction pads are supplied
with compressed air which ensures that the suction pads are released quicker from the
load.
As a result of the own weight of the OKTOPUS
®
there is still vacuum re-
maining after venting the suction pads through the vacuum system. Lifting
the OKTOPUS
®
jerkily increases this effect. For this reason, always remove
the device slowly and evenly from the installed elements!
