Handling and lifting of VLT
®
DriveMotors (FC motors)
must only be undertaken by qualified personnel. Full
product documentation and operating instructions
must be available together with tools and equipment
necessary for safe working practice. Eyebolts and/or
lifting trunnions supplied with the FC motor are
designed to support only the weight of the FC motor,
not the weight of the FC motor and any auxcillary
equipment attached to it. Be absolutely sure that
cranes, jacks, slings and lifting beams are capable of
carrying the weight of equipment to be lifted.
■
Handling the FC motor
Where an eyebolt is provided with the motor,
this should be screwed down until its shoulder is
firmly against the face of the stator frame to be lifted.

Bearings.
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.
