2.5 Conditions and restrictions of application
The glass and cladding elements to be processed with the OKTOPUS
®
GL-RN 400/600/800
have to fulfil the following criteria in the suction areas:
•
they have to be airtight,
•
they must have a smooth, dry, oil-free and clean surface and
•
they must not be equipped with a protective plastic film.
The OKTOPUS
®
shall be delivered with suction pads for smooth glass and cladding elements.
Generally, no statements can be made on the length and the width of the elements to be in-
stalled with the OKTOPUS
®
, as this depends - upon observing of the safe work load criteria -
almost exclusively on the inherent rigidity and the deformation behaviour of the construction el-
ements connected thereto.
The suction of oil, water, vapours or aggressive gases shall be avoided. The ambient tempera-
ture shall be min 0 °C and may be max 40
°
C (valid for 1013 mbar and sea level). At low tem-
peratures the capacity of the batteries in use is reduced. The airborne sound deriving from the
OKTOPUS
®
GLASS-Jack GL-RN 400/600/800 is < 70 dB(A), vibrations are at < 2.5 m/s
2
, so
that no special protective measures are required.
Limitations of application arise from the limited Working Load Limit of the OKTOPUS
®
GLASS-
Jack GL-RN 400/600/800 (see section 2.3 Symbols and markings) as well as from the capacity
data, the conditions of application of the crane to be used and the building site conditions. Fur-
thermore, it shall be taken into account that the element to be installed should be of sufficiently
inherent stability and appropriate for mounting by vacuum lifting attachments (to be clarified with
the elements‘ manufacturer if so).
Due to the large number of the elements existing in the market and their surface coatings, we
cannot take over liability in case of possible material incompatibilities between suction pad and
surface coating.
The maximum Working Load Limit stipulated on the OKTOPUS
®
only applies to the use of the
original suction pads and a working height of maximum 400 m above sea level. Employing the
OKTOPUS
®
in heights above 400 m leads to a decreased Working Load Limit of the OK-
TOPUS
®
on the one hand, on the other hand the OKTOPUS
®
control system needs to be ad-
justed. If you want to employ the OKTOPUS
®
in heights above 400 m, please contact the Wirth
Service Team beforehand.
Employing the OKTOPUS
®
at heights above 400 m leads to a decreased Work-
ing Load Limit! The Working Load Limits stipulated on the OKTOPUS
®
and in
this operating manual do not apply in this case!
Never carry out unauthorized adjustments at the control system of the OK-
TOPUS
®
as it may lead to serious malfunctions of the device! It means danger
to life and limb! Consult with the OKTOPUS
®
manufacturer if it is necessary to
adjust the control system of the OKTOPUS
®
, e.g. for height adjustment.
