•
Use both lifting lugs when provided.
•
For vertical lift, prevent uncontrolled rotation.
•
For lift machine, do not lift other equipment
with motor lifting points only.
Only qualified personnel must undertake handling and
lifting of the unit. Ensure:
•
Availability of full product documentation,
together with tools and equipment necessary for
safe working practice.
•
Cranes, jacks, slings, and lifting beams are rated
to bear the weight of the equipment to be lifted.
For weight of unit, see chapter 6.1.5 Weight.
•
When using an eyebolt, that the shoulder of the
eyebolt is tightened firmly against the face of the
stator frame, before lifting.
Eyebolts or lifting trunnions supplied with the unit are
rated to bear the weight of the unit only, not the
additional weight of ancillary equipment attached.

3.3.3 Bearings

The standard solution is fixed bearing in the drive side of
the motor (shaft output side).
To avoid static indention, ensure a vibration-free storage
area. Where exposure to some vibration is unavoidable,
lock the shaft. Bearings may be fitted with a shaft locking
device, which should be kept in place during storage.
Rotate shafts by hand, 1/4 of a revolution, at weekly
intervals.
Bearings are despatched from the works fully charged with
lithium-based grease.
