3.10 Motor swing base (option: MS)
A motor swing base is a steel structure for pre-assembled drive packages in a horizontal position. It
serves for jointly mounting gear unit, (hydro) coupling, motor, and, where applicable, also a
mechanical brake, and it comes with the necessary protective devices (e.g. hood). The steel structure
is supported by the drive shaft and a torque arm.

Installation and assembly
WARNING
Hazards from rotating parts
There are moving parts (e.g. shafts) on the individual components of the drive package. These can
rotate quickly and lead to injuries (e.g. crushing, strangling, etc.).
• Do not operate the drive without covers or hoods.
• Secure the drive against inadvertent switching on during installation work.
• Pay attention to the additional information contained in the operating and assembly instructions for
third-party components.
• Pay attention to the job-specific information on brake and coupling components contained in the
dimension sheet or the order confirmation.
NOTICE!
Risk of gear unit damage from faulty installation
Impermissible tension, distortion and poor stability can damage the gear unit and attached
components.
• Use the right lashing points.
• Install the drive package on a horizontal and level surface.
• Ensure that foundation and torque arm are dimensioned adequately.
• Do not exceed the maximum permissible distortion of 0.1 mm at a distance of 1 m.
• Check and correct the alignment of mounted components (Pay attention to the manufacturers’
documentation).
• Ensure a non-distorted alignment to the shaft of the connected machine.
Impermissible distortion and poor stability of the gear unit significantly affect the wear pattern of gear
wheels, the load on the bearings, and consequently the service life of the gear unit.
