Cooling
NOTICE
Dust deposits prevent heat radiation
Dust deposits prevent heat radiation and cause a high housing temperature.
Keep the gearbox free from dirt, dust, etc.
The gearbox does not normally require additional cooling. The generously dimensioned
housing surface is sufficient for dissipating heat losses where there is free convection. If the
housing temperature exceeds a value of +80 °C, please contact Technical Support.
11.3.6
Fastening for suspended transport
WARNING
Inadequately fastened gearboxes or geared motors can break loose
Use only the transport eye or eyebolt of the gearbox to transport the gearbox or geared
motor. Because they are designed only for the weight of the gearbox or geared motor, it is
not permissible to add additional loads.
Do not rig eyebolts to the front threads at the shaft ends for transportation purposes.
Do not use the integrally cast lifting eyes on the motor for transport because of the risk of
breaking.
If necessary, use additional, suitable lifting accessories for transport or during installation.
When attaching by a number of chains and ropes just two strands must be sufficient to bear
the entire load. Secure lifting accessories against slipping.
