4. HANDLING AND TRANSPORT

Individually packaged motors should never be lifted by the shaft or by the packaging. They must be lifted only by
means of the eyebolts, when supplied. Use always suitable lifting devices to lift the motor. Eyebolts on the frame
are designed for lifting the machine weight only as indicated on the motor nameplate. Motors supplied on pallets
must be lifted by the pallet base with lifting devices fully supporting the motor weight.
The package should never be dropped. Handle it carefully to avoid bearing damage.
Eyebolts provided on the frame are designed for lifting the machine only. Do not use these eyebolts for
lifting the motor with coupled equipment such as bases, pulleys, pumps, reducers, etc.
Never use damaged, bent or cracked eyebolts. Always check the eyebolt condition before lifting the motor.
Eyebolts mounted on components, such as on end shields, forced ventilation kits, etc. must be used for lifting
these components only. Do not use them for lifting the complete machine set.
Handle the motor carefully without sudden impacts to avoid bearing damage and prevent excessive mechanical
stresses on the eyebolts resulting in its rupture.
To move or transport motors with cylindrical roller bearings or angular contact ball bearings, use always
the shaft locking device provided with the motor.
All HGF motors, regardless of bearing type, must be transported with shaft locking device fitted.

4.1. LIFTING

Before lifting the motor ensure that all eyebolts are tightened properly and the eyebolt shoulders are in
contact with the base to be lifted, as shown in Figure 4.1. Figure 4.2 shows an incorrect tightening of the
eyebolt.
Ensure that lifting machine has the required lifting capacity for the weight indicated on the motor nameplate.

The center-of-gravity may change depending on motor design and accessories. During the lifting
procedures the maximum allowed angle of inclination should never be exceeded as specified below.

4.1.1. Horizontal motors with one eyebolt

For horizontal motors fitted with only one eyebolt, the maximum allowed angle-of-inclination during the lifting
process should not exceed 30º in relation to the vertical axis, as shown in Figure 4.3.
