Transport and storage
• The lift machines leave the factory in perfect condition after being tested.
• Make a visual check for any external damage immediately upon their arrival on site. If any damage is found
to have occurred in transit, make a notice of claim in the presence of the carrier. If appropriate, do not put
these machines into operation.
• Observe the relevant safety regulations and take the centre of gravity into account when handling the lift
machines.
• Check that the eyebolts are tightly fitted before using them.
• Do not expose the motor to any shocks or impact.
Storage
• Store the motors only in closed, dry, dust-free, well-ventilated and vibration-free rooms (storage tempera-
ture: -20°C to 60°C). Do not store lift machines in the open air. Bright parts are not sufficiently preserved to
withstand extended periods of exposure.
• Avoid excessive storage periods (recommendation: max. one year).
• After prolonged storage (>3 months), rotate the motor in both directions at a low speed (< 20 min
-1
) to allow
the grease to distribute evenly in the bearings.
• Measure the insulation resistance before initial operation of the machine. If the value has dropped below
1 k
W
per volt of rated voltage, the winding needs to be dried (insulation meter voltage: 1,000 VDC).
• This can be done, for instance, with hot air, in a drying oven, or
by applying a DC voltage to the motor connections. Make sure
that the voltage selected does not exceed the values shown in
the figure "Drying the winding". Let the temperature rise to
about 70 – 80°C and maintain it for several hours.
Unpacking
• Dispose of the packaging material in an environmentally friendly manner or reuse it.
• Any special transport aids or shipping braces are left with the customer.
WARNING
The eyebolts are designed for the specified machine weight, i.e. additional loads must not be
applied. Danger of breakage!
