3.3.2 Lifting
NOTICE
LIFTING - EQUIPMENT DAMAGE RISK
Incorrect lifting can result in equipment damage.
•
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.
Handling and lifting of the unit must only be undertaken
by qualified personnel. 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 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, the storage area should be
vibration free. Where exposure to some vibration is
unavoidable, the shaft should be locked. Bearings may be
fitted with a shaft locking device which should be kept in
place during storage. Shafts should be rotated by hand,
one quarter of a revolution, at weekly intervals.
Bearings are despatched from the works fully charged with
lithium-based grease.
3.3.4 Bearing Life and Lubrication
The life expectancy of the ball bearings is standard, when
the following conditions are fulfilled:
•
temperature of 80
°
C
•
radial forces in load point corresponding to half
shaft extension do not exceed the values
specified by motor manufacturer
