Take up the slack in the lifting device very carefully and manually
stabilize the switchgear to prevent it from rotating.
WARNING: Do not stand under switchgear while it is being
moved. Serious injury may occur if the cables or lifting device fail.
AVERTISSEMENT: Ne vous tenez pas sous le dispositif de
commutation lorsqu’il est bougé. Des blessures graves peuvent
survenir si les câbles ou l’appareil de levage tombent en panne.
CAUTION: Gently lower the switchgear section onto the level site
location. If the switchgear is roughly handled or jarred, it is
possible to damage or misalign internal components.
ATTENTION: Abaisser doucement la section du dispositif de
commutation sur l’endroit d’installation nivelé. Une détérioration
ou un désenlignement des composantes internes sont possibles
si le dispositif de commutation est manipulé grossièrement ou
soumis à des vibrations.
Methods of lifting outdoor switchgear sections are much the same as
for indoor equipment except the lifting plates are provided at the base
of the structure. See Fig. 2-4.
If lifting outdoor switchgear sections, side support timbers must be
placed along the sides to prevent any damage that could be caused
by the lifting cables. In addition, a spreader bar must be inserted
between each lift cable, both front and rear, above the switchgear
equipment as shown in Fig. 2-5. Proceed to lift and place the outdoor
switchgear utilizing all the precautions and requirements that apply
to lifting the indoor switchgear.
The lifting plates, Fig. 2-4, should be removed after the equipment is
permanently anchored so passageways at the ends of the equipment
will not be obstructed.
Rollers
If crane facilities are not available, the equipment may be moved into
position by means of construction rollers placed under the shipping
skids. The switchgear may be raised enough for the placement of
rollers by means of a fork lift or jack.
There should never be less than four rollers under the equipment
unless the line-up is less than five feet long. Use one roller for each 18
inches of equipment length.
Forklifts
When using a forklift to raise the line-up to position rollers
underneath, proceed as follows:
1. Expand forklift tines to their maximum (widest) extension.
2. Carefully insert tines of forklift below one side of the
switchgear line-up at the approximate center of the panel as
shown in Fig. 2-6.
NOTE: Do not attempt to lift or move the equipment with a forklift
positioned in the front or rear of the equipment.
NOTE: Ne pas essayer de lever ou bouger cette pièce
d’équipement à l’aide d’un chariot élévateur placé à l’avant ou à
l’amère de celle-ci.
3. Raise equipment and position one roller under the skids close to
the raised end of the line-up.
4. Carefully lower the gear until it rests on the roller as shown in
Fig. 2-7.
5. Repeat the lifting process at the other end and place the
appropriate number of rollers under the skids spacing them
evenly across the width of the line-up.
