Entellisys Low Voltage Switchgear
Chapter 2. Receiving, Handling, and Storage
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 shipping 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).
