Handling
Notice:
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.
Indoor enclosure lifting
The indoor switchgear sections are best handled by
lifting with a crane as shown in Fig. 04. 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.
Warning:
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.
Connect a cable from the crane to the four lifting
plates located on the top-front and rear of the
switchgear (Figure 04).
