3.11 Motor swing base (Option: MS)
A motor swing base is a steel structure for pre-assembled drive packages in a horizontal position. This
is used to mount the gear unit, (hydro) coupling, motor, and where applicable, a mechanical brake. It
also comes with the necessary protective devices (e.g. cover cap, Option H). The steel structure is
supported by the drive shaft and a torque arm.

Installation and assembly
Impermissible tension, distortion and poor stability can damage the gear unit and attached
components. They significantly affect the wear pattern of gear wheels, the load on the bearings, and
consequently the service life of the gear unit.
Components between the motor and the gear unit, e.g. turbo couplings or brakes are pre-adjusted
prior to delivery. Check and adjust the alignment and settings of these components according to the
corresponding manufacturer’s documentation prior to commissioning the gear unit. Incorrect alignment
will result in premature failure of the attached components and the gear unit.
Install the drive package on a horizontal and level surface. Ensure that foundation and torque arm are
dimensioned adequately. The maximum permissible distortion is 0.1 mm at a distance of 1 m.
Ensure a non-distorted alignment to the shaft of the connected machine.
Pay attention to the job-specific information of brake and coupling components contained in the
dimension sheet or the order confirmation, as well as all notes on installation and assembly contained
in the separate operating and installation instructions of all installed components.
