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.
NOTE: Il est préférable de laisser l’emballage d’expédition en
place sous le dispositif de commutation jusqu’à ce qu’il atteigne
son emplacement final. L’équipement devrait être installé à son
emplacement final avant que ne soient installés les disjoncteur.
Lifting
The 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 equipments 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.
NOTE: Il faut que l’angle entre les câbles et le haut de
l’équipement soit d’au moins 45 degrés. Si cela est impossible à
cause d’une insuffisance d’espace de dégagement, il faut utiliser
des barres d’extension. Il se peut aussi que des câbles de levage
ayant une capacité de poids supérieure soient nécessaires
dépendant de l’angle 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).
