WARNING
Transporting or lifting the machine
The motor or the motor set may only be transported and lifted with the hoisting lugs, as it
might otherwise tip over or slip out of the lifting equipment. Death, serious injury, or material
damage can result.
● Always use the lugs on the stator frame to lift the motor. Use suitable rope guidance or
spreading devices. You will find the weight of the motor on the rating plate.
● Only lift and transport the motors in a position appropriate to their design.
● Vertical-design motors must always be transported in the vertical position if the rotor is
not fixed. If transport in a horizontal position should prove to be necessary in special cases,
then fix the rotor before bringing the motor the horizontal position. If necessary, vertical
motors with suitable bearings are supplied by the manufacturing plant in the horizontal
position.
Note
Place the machine in a secure and raised position
In order to obtain easy and safe access to the underside of the machine, place it in a secure
and raised position.
DANGER
Standing under suspended loads
If the lifting gear or load handling attachments were to fail, the machine could fall. This can
result in death, serious injury or material damage.
Never remain under or in the immediate vicinity of the machine when it is raised.
