3. Storage, transport, preparation, installation
3.1 Storing the gear unit
For short-term storage before commissioning, please observe the following:
 Store in the fitting position (see Section 6.1) and secure gear units against falling
 Lightly grease bare metal housing surfaces and shafts
 Store in dry rooms
 Temperature in the range from –5
o
C to +50
o
C without large fluctuations
 Relative humidity less than 60%
 No direct exposure to sunlight or UV light
 No aggressive, corrosive substances (contaminated air, ozone, gases, solvents, acids,
alkalis, salts, radioactivity etc.) in the immediate vicinity
 No vibration or oscillation
3.2 Long-term storage
Note!
For storage or standstill periods in excess of 9 months, Getriebebau NORD
recommends the long-term storage option. With the long-term storage option and the
use of the measures listed below, storage for up to 2 years is possible. As the actual
influences on the unit greatly depend on the local conditions, these times should only
be regarded as guide values.
Conditions of the gear unit and storage area for long-term storage prior to
commissioning:
 Store in the fitting position (see Section 6.1) and secure gear units against falling
 Transportation damage to the external paint must be repaired. Check that a suitable rust
inhibitor is applied to the flange bearing surfaces. If necessary apply a suitable rust inhibitor
to the surfaces.
 Gear units with the long-term storage option are completely filled with lubricant or have VCI
corrosion protection agents added to the gear oil. (See label on gear unit)
 The sealing band in the vent plug must not be removed during storage. The gear unit must
remain sealed tight.
 Store in a dry place.
 In tropical regions, the drive unit must be protected against damage by insects
 Temperature in the range from –5
o
C to +40
o
C without large fluctuations
 Relative humidity less than 60%
 No direct exposure to sunlight or UV light
 No aggressive, corrosive substances (contaminated air, ozone, gases, solvents, acids,
alkalis, salts, radioactivity etc.) in the immediate vicinity
 No vibration or oscillation
Measures during storage or standstill periods
 If the relative humidity is <50% the gear unit can be stored for up to 3 years.
