RECEIVING, HANDLING AND STORAGE
3.1
RECEIVING
All motors were tested and are in perfect operating
conditions. The machined surfaces are protected against
corrosion. The package must be inspected upon receipt
for occasional damages during transportation.
ATTENTION
Any damage must be photographed,
documented and reported immediately to the
carrier, the insurer and WEG. The non-
communication of this damage will void the
warranty.
ATTENTION
Parts supplied in additional packages must be
checked upon receipt.
When lifting the package (or container), the proper
hoisting points, the weight indicated on the package or
on the nameplate and the operating capacity and
conditions of the hoisting equipment must be observed;
Motors packed in wooden crates must always be lifted
by their own lifting lugs or by a proper forklift; they must
never be lifted by the package;
The package can never be overturned. Place it on the
floor carefully (without impact) in order to avoid damage
to the bearing;
Do not remove the grease for protection against
corrosion from the shaft end, or the closing plugs
present in the terminal box holes. These protections
must remain in place until the moment of the final
assembly.
A complete visual inspection of the motor must be
carried out after removing the package;
The shaft locking system must be removed just before
the installation and stored to be used in future
transportation of the motor.
3.2
HANDLING
ATTENTION
In order to move or transport the motor, the
shaft must be locked with the locking
device supplied with the motor.
Lifting equipment and devices must be able
to withstand the motor weight.
Failure to comply with these
recommendations may cause damage to the
equipment, personal injuries or both.
NOTES
Observe the indicated weight. Do not lift
the motor causing jolts or put it down
abruptly on the floor, because this may
cause damage to the bearings;
In order to lift the motor, use only the lifting
lugs provided for that purpose. If
necessary, use a crossbeam to protect
parts of the motor.
The lifting lugs on the heat exchanger, end
shields, bearings, radiator, terminal box,
etc. are designed to handle these
components only separately;
Never use the shaft to lift the motor;
The frame lifting lugs are intended to lift
only the motor. Never use them to lift the
motor-driven machine set.
