2.2 Handling
Note: It is preferable to leave the shipping skids in
place under the switchgear until it reaches its final
location. The equipment should be installed in its
final location prior to installing the circuit breakers.
Remarque: Il est préférable de conserver les
cales d'expédition à leur place sous l'appareillage
électrique jusqu'à ce que celui-ci ait atteint sa
destination finale. Installez l'équipement dans
son emplacement final avant d'installer
les disjoncteurs.
Indoor enclosure lifting
The indoor switchgear sections are best handled by
lifting with a crane as shown in Fig. 2.3. Removable
lifting plates are provided, as standard equipment,
on the top of each switchgear section. To preserve
the external appearance of the equipment, it is
suggested that the lifting plates be left in place
except where adjacent equipment must be bolted
together, i.e. shipping splits, etc.
Utilize four equal length cables and an overhead
crane, each with a minimum load rating of twice the
weight of the switchgear. Estimated weights for
shipping splits appear on the Front View drawings.
Example: Switchgear section weight = 5,000
pounds. The crane and the four lift cables must
have a minimum load lifting capacity of
10,000 pounds.
Note: The angle between the cables and the
top of the equipment must be at least 45
degrees. If this is not possible because of
lack of headspace, spreader bars must be
used. Also, lift cables with greater load
capability may be necessary, depending
upon the angle between the cables and
the crane hook.
Remarque: L'angle entre les câbles et le haut
de l'équipement doit être d'au moins 45
degrés. Si l'espace est insuffisant pour cela,
vous devez utiliser des barres d'écartement.
Il est également possible que vous ayez à
utiliser des câbles de levage présentant une
capacité de charge supérieure, en fonction
de l'angle existant entre les câbles et le
crochet de la grue.
Connect a cable from the crane to the four lifting
plates located on the top-front and rear of the
switchgear (Fig. 2.3).
